Samsung Galaxy charging bug

I am enjoying my Galaxy Note 9, but unfortunately there is a bug with wireless charging. Apparently it happens with a number of Samsung phones: we pop them on the wireless chargers at airports etc, and suddenly they stop charging. We get a message stating "Wireless charging has paused", no other explanation, no way to turn wireless charging back on, and no magic black lightning bolt inside the battery icon at the top of the screen.

Even more worrying is that often the battery seems to discharge more quickly than usual when on the charge pad. I was overseas and watched my battery discharging at what appeared to be break-neck speed while supposedly on charge (I know, first world problems, but I was jet-lagged :-D).

A quick search on the internet found me a solution by Hisona (8 December 2018). All we have to do is to reboot the phone via a battery pull. Of course, doing that when we can't get the battery out appears to be of a problem, but the same effect is created by doing the following:
  • Press and hold the volume down button. Keep holding it down, don’t release it, then
  • While holding down the volume down button, press and hold the power key, then
  • Hold both keys down for over 10 seconds, then
  • The phone should reboot.
We will know the phone has rebooted because the battery image will appear in the middle of the black screen with the amount of charge remaining, and if we put the phone on a charging pad, we will see the black lightning bolt.

I had 'the bug' twice while I was overseas. Both times Hisona's fix worked for me (8 December 2018). However, if this doesn't work, there are some more hardcore fixes available here.

Issue 175, November 2009

Hi guys,

In a post-recession world, how can we take better care of our customers? Check out Eco-Economy below.

I have some stats from Trendwatching that indicate we will be Online 24/7 by 2014. 


Don't forget, if you want to be taken off my mailing list, click here to send me a reply e-mail and I will remove your name.



Eco-Economy



Some coming trends to think about as the world climbs out of the current recession may make the difference between businesses that take off and those that crawl.

A few interesting pieces of news came across my desk this week, which got me thinking about about the new links between ecology and economics:

  • Apple has apparently refused to repair PCs which belong to customers who smoke, advising that nicotine is on the Occupational Safety and Health Administration's (OSHA) list of hazardous substances and Apple would not require an employee to repair anything deemed hazardous to their health. A US Consumerist website claims to have received reports from two Mac users stating that US Apple repair centres have declined to fix 'Applecare'-warrantied PCs, claiming that the warranties have been voided due to second-hand smoke contamination under OSHA regulations (while it is entirely logical that nicotine and other toxic cigarette residues would seep into computers over time, providing a health risk for Mac techies when fixing them is a bit of a stretch). See http://apcmag.com/apple-wont-work-on-macs-owned-by-smokers.htm
  • Bundanoon in NSW, taking inspiration from the Tasmanian town of Coles Bay which went 'Plastic Bag Free' in 2003, is Australia's first bottled-water free town. To put to rest repeated consent applications from the Norlex conglomerate, which wanted to drill for bottled water, the townsfolk responded by banning bottled water completely (http://www.bundanoon.nsw.au/bundy-on-tap.html), and installing filtered drinking fountains.
  • And speaking of plastic bags, New Zealanders use 1 billion plastic shopping bags per year (a mind boggling over-consumption for a mere 4 million people), but China - with a population of two billion - knocks us into a cocked hat for green practices. They have reduced their use of plastic bags 66% in the first year of legislating against single-use plastic bags by an amazing 40 billion bags, from kick-off in June 2008 through to June 2009 (http://www.chinaretail.org/shownews.asp?id=766). Collingwood is Nelson's only plastic bag free town; although Wanaka and Kaikoura have now followed suit. However, the worst on the planet are the Americans, who throw away almost 100 billion plastic bags every year, only recycling between 1 and 3 percent. Hong Kong, Kenya, Tanzania, Bangladesh, Germany and the Netherlands are all plastic bag free. Denmark, Belgium, Switzerland and Ireland have a plastics tax.
  • Soda stream is being advertised on TV again - probably for the first time since the 70s, by my recollection - with the pull strategy of the young Australian boy on the ad saying that they were not contributing to landfills by using soda stream, and that soda stream is an "Active Green" company as it consumes CO2. Quite a different marketing ploy to the 1970s and early 80s (http://www.sodastream.com.au/earthfriendly).

So what do all these things have in common? That in our post-recession, hyped-up global-warming world, the human race is starting to think about becoming a whole lot less wasteful, and I suspect in the medium term we will be a lot more careful of what knock-on effects we create. Mr FastFoodChain and Ms Supermarket need to take into account that a few greener practices will get customers onside; being clever about not creating the waste in the first place, so we don't have to deal with it later, will stand businesses in good stead.

Time and time again it has been proved that the only way to change our profligate habits has been legislation. However, while New Zealand's Waste Minimisation Bill was a total fizzer, there is nothing to stop each and every one of us from doing our bit, personally and in our own businesses.

Individually we can all make changes in how we do things; which will in turn keep our costs down. We can pass on savings directly to our customers, or pass those savings on to causes that we - and our customers - are passionate about, such as those reported this week by Trendwatch in Holland - http://trendwatching.com/briefing/#embedded.

Something for us all to think about.

 



Online 24/7



I was just reading on Trendwatching's website some projections of our mobile data use (at http://trendwatching.com/briefing/). We are apparently going to be quite "well connected" by 2013 or 2014:

  • Globally, mobile data traffic will double every year through 2013, increasing 66-fold between 2008 and 2013. Mobile data traffic will grow at a CAGR of 131% between 2008 and 2013, reaching over 2 exabytes per month by 2013 (Cisco, 2009)
  • The number of Orange 3G mobile broadband customers had increased to 21.7 million at 30 June 2009, compared with 13.4 million in June 2008, an increase of 62% in one year
  • The overall number of individual mobile users in Western Europe is set to grow to 344 million at year-end 2014. By 2014, a third of Western European consumers will own internet-enabled phones compared with 18% in 2009. Mobile Internet adoption is set to grow to 39% in Western Europe in 2014 from 13% in 2008 (Forrester Research, August 2009)
  • 6.5 billion tweets sent from Twitter thus far

Makes you wonder where you can cash in, and what trends you need to be up with, doesn't it...



Detecting Wireless Freeloaders



If you have a wireless network that suddenly starts slowing down, you may have someone else freeloading downloads on your account. And when you suddenly want to find out who else may be tapping into your network, most of us are a bit stuck.

However, there is an easy way to see which IP addresses are connecting to your router - and that is to query your router.

What you want is your router's status page. Anyone with network access to the router can see the status page simply by typing the router's LAN address into their browser's address bar (eg D-link at http://192.168.0.1/). Some routers may require a bit more navigation to get to the page that displays who's connected, but it is usually fairly easy.

Hey presto! There's the information you're looking for.

On home wireless networks, just compare the number of PCs the router says are connected to the number you should have. If you should have two and there are three connections, you know there's a problem and you need greater security. You might find there is a car parked on the street with someone in it. You could try turning your router off & see if they drive away. Then get some advice on how to better secure your internet connection (or do it yourself by reading the following article at http://windowssecrets.com/2009/10/08/07-Take-steps-to-secure-your-home-networks-router).

For larger setups, turn on all the machines you want connected to the LAN, note their IP addresses, and scan the router's list for "alien" IPs.

Bookmark your router's home page (IE - Add to favourites). Then you can check for anyone who shouldn't be on your router with a single click.

Newsletter Issue 67, September 2003


Sam Young Newsletter

Issue 67, September 2003
Hi guys,
In this issue we have part two in our Wired vs Wireless articles (continued from issues 65), in Wireless Technology.
Want an easy way to count actual data rows in Excel? Then check out the tips on Using DCOUNTA in Excel
Don't forget, if you want to be taken off my mailing list, click here to send me a reply e-mail and I will remove your name.

Wireless Technology

In the first August issue (issue 65), we looked at what kind of network you might be thinking of using. This time we are looking at what kind of gadgets you might want to use on the network you are going to invest in.
So Just How Mobile Did You Want To Be? 
The mobile Internet is supposedly finally reaching all of us. There are fancy new gadgets such as camera phones and walkie-talkie handsets that let you watch movie trailers, send kids pics to Nana's cell phone and let you fritter away any time you have left playing ant-size PacMan. 
You can get PDAs with built-in phones (a bit clunky but they work) for a couple of K. And don't forget the Tablet PC - mobile, go anywhere PC power.

The Limitations
OK. So what are the limitations on being mobile? Battery power for one. You don't get that much battery life time with these toys. For now you need regular recharging. Granted, if you saw issue 65, you would know that there is a great new up & coming battery, but it will take another year or so to get commercial. 
The other limitation is the folding stuff. Mobile phones have lots of technology, but are there enough tricks and gadgets to make you want to pay extra to get it?
Tablet PCs offer all the features of standard laptops, plus a radio-wave-transmitting pen that can be used to take notes or draw right on screen. They're becoming more and more accepted. 
And there are some interesting trends happening overseas. In the US, by November, carriers have to let customers take their cellphone numbers with them when they switch providers. So Telcos are falling over each other to offer distinctive add-on services to encourage people to either stay loyal (or to switch to them).
But despite lots of encouragement, the only non-voice phone use that has really caught on of late is texting, with 22 percent of mobile phone users sending wireless text messages.
And I don't think providers got the mix right yet on truly useful mobile tools - not those that people will pay lots extra for data services for anyway. For me? I'm waiting to be able to enter a barcode into my "Pocket Google" phone/PDA so I can really comparison shop. And I'd love a talking calendar that let me voice-select everything - including days, times and contacts to record my appointments on; and email a confirmation to the people I have made the appointment with!

What Toys You Can Get Right Now
Smart phones
  • Sanyo SCP-8100: You can get a faint glimpse of the Internet of the future over the Sanyo SCP-8100 mobile phone. It features a mid-sized handset with full-colour screen and built-in camera. Thanks to the extra memory and processing power in the Sanyo 8100, navigation is much faster than it was on wireless Web cellphones two years ago, but not as fast as your dial-up Internet on your desktop computer. Its a little like on-demand radio, with a fuzzy image or two thrown in
  • Sony Ericsson P800: This phone comes complete with a digital camera, a video player, an MP# player, 3D games and an organiser with a colour touch screen. It has polymorphic sound, Java, Bluetooth & MMS (multimedia messaging). This wee toy was featured in the latest James Bond incarnation "Die Another Day".
Wireless PDAs - You will need to pay to connect your PDA with mobile network by what? The expectation is that PDA prices will drop 16% this year and the market will grow 11%. 
The Palm OS is still the most common operating system, but Windows CE and Symbian OS are both gaining ground. So take your pick!
  • HP iPaq H1940: Super-compact, sharp screen, Bluetooth; removable battery & relatively inexpensive with a Secure Digital slot that supports SDIO cards
  • Palm Zire 71: Runs Palm OS 5.2.1, high-res screen, fast processor, built-in camera, MP3 support, expansion slot, Secure Digital (SD) expansion slot, slick design; but no Bluetooth. 
  • Palm Tungsten T2: Compact design, 32MB of RAM, excellent screen, integrated Bluetooth, Palm OS. Can add storage space or devices via the unit's SDIO-compliant SD/MMC slot, has MP3 support & video support. But you really need a Bluetooth cell to use this machine to the full - use a Bluetooth-enabled wireless phone as your modem for Internet access...
Tablet connectivity: get USB 2.0 jacks and, if you want to hook your tablet up to your TV, S-Video. You will also want Ethernet wired network jack for business networking and possibly FireWire, (aka IEEE 1394) to transfer digital video from camcorders to the tablet for editing
  • Compaq Presario X1000 is heavy - 3 kgs - but it's a very full- featured machine (would serve as a desktop replacement). It has a 15 & 1/2 inch screen and a built-in Secure Digital/ Multimedia memory card slot, just perfect for popping a card out of a digital camera and into the laptop to transfer pictures
  • Fujitsu LifeBook S2000 was one of the smallest fully featured units - just under 1.7kgs without the DVD/CD-RW drive, and 2 kgs with the drive installed. It packs pretty much everything you need in a laptop into a very compact space. The keyboard might feel a bit tight at first, but after a bit of persevering, it turns out to be fine to work on
  • The Apple PowerBook uses space very wisely, having almost a full-sized keyboard layout. Bluetooth is standard, so you have short distance wireless for transferring information to printers and mobile phones (around 3 metres or under). The PowerBook has a 12-inch screen which is about as small as you would want to go but it provides terrific resolution - and if you don't need to scroll through lots of spreadsheets or docs, it will do nicely.

Using DCOUNTA in Excel

Excel's DCOUNTA function finds and counts the number of records that meet specific criteria, such as how many employees were hired before January 1st 2000, or how many customers live in one city. 
For example, to find out how many people in an employee spreadsheet live in Christchurch, follow these steps: 
  1. Insert two blank rows above the range, and copy and paste the column headings into the first blank row
  2. In the second blank row, enter Christchurch in the cell under the City field. 3. In another cell outside the criteria range, enter =DCOUNTA( 
  3. Type the range or named range. For example, if the range is named Employees, enter that name as the first argument to the formula: =DCOUNTA(Employees, 
  4. Type the field name that you want counted. For example, if you want to count the number of records that have an entry in the Last_name field and whose City field contains the text "Christchurch," enter: =DCOUNTA(Employees,"Last Name", 
  5. To complete the formula, enter the criteria range, which in this example is A1:L2, and press [Enter]: =DCOUNTA(Employees,"Last Name",A1:L2) The total number of employees living in Christchurch will be displayed. 
Now that the criteria range has been set, you can use DCOUNTA for other ad hoc reporting functions; just enter different criteria. 

Templates Anyone?

Finding a template "to do that thing that you want to do" can save you lots of time; print a calendar, write a newsletter, put together a budget. So if you are trying to do something that others must have already done, spending a few minutes searching for that magic template could save you frustration and time. 
As well as freebees that you can probably find on the net, there are a number of people who sell Office templates. Check the ones out below first: 

TLAs for SMEs

Here are this newsletter's TLAs for you;
  • RDBMS, Relational database management system. A program that lets you create, update, and administer relational databases. Most commercial RDBMS's use SQL for database access
  • SQL, Structured Query Language. A standard interactive and programming language for getting information from and updating a database. SQL was invented after the development of the relational database model and is was not developed for that use, but fits in very neatly with it
  • OSI, Open Systems Interconnection. A standard description or "reference model" for how messages should be transmitted between any two points in a telecommunication network
Please feel free to email me with any TLAs that you want to get the bottom (meaning!) of.

Newsletter Issue 65, July 2003


Sam Young Newsletter

Issue 65, July 2003
Hi guys,
There's a brand new battery in town. Check it out in Never Mind the Flatulence Tax below.
Wanting some clarification on  Wireless vs Wired Networks? Then read on.
Don't forget, if you want to be taken off my mailing list, click here to send me a reply e-mail and I will remove your name.

Never Mind the Flatulence Tax

There has been a lot said in the media recently about the flatulence tax. In fact, it completely beggars the imagination what an awful thing this is going to be... despite the fact that - as I understand it - the sums we are talking about are paltry (costing only a couple of hundred dollars a year per farm).
But in some reading I have been doing lately, there is a major spin off to the production of all that flatulence that farmers could capitalise on, if they could stop carping long enough to carpe diem.
Toshiba have just unveiled a new battery, the DMFC or Direct Methanol Fuel Cell. It uses Methanol from the battery and oxygen in the air to directly power portable PCs, PDAs etc.
While the length of time the batteries run isn't staggering, it's still pretty good, one battery running an XP Laptop for 10 hours. Toshiba are aiming to get power outputs up to 24 hours from one battery.
The great thing? Methanol in this form is pretty stable, easily available (think of all those cows!), will be refillable, will end up the size of a sugar cube and is a "greener" technology than the old lithium-ion batteries.
How refillable? Go to your local Shell station and "fill 'er up". And, currently in Japan the first wireless fuel cell vending machine has hit the streets, so this technology looks as if it will be a go.
Sounds great. So it will probably be years away, right? Wrong. End of 2004.
But I think we can safely say that it will be pricey for now. So all you farmers out there had best start hanging on to your flatulence. You will be able to sell it before long...

Wireless vs Wired Networks

We have all heard the hype. Replace our normal phones with internet capable "Smart" phones, go wireless, replace your laptop with a PDA, buy a tablet PC and get a fixed point network. There is so much going on that it's pretty confusing. So what should you be thinking about, and why? 
How Mobile Do You Need To Be? 
First things first. Do you truly need to be mobile? Think long and hard about what your real needs are. If you just miss appointments, perhaps you only need get a Personal Digital Assistant (PDA) or electronic diary that you can dock with Outlook on your PC to synchronise your calendar easily. If you need to work on the train or at airports, perhaps you should get a laptop. Then again, you may need to update your stock system from anywhere in New Zealand and so need a tablet PC that uploads every change via a Tablet PC.
Then to Networks… 
So how do you connect to your data? Choices - you can go wired network or wireless. 
The wired network is that one using the phone cable that you plug in, or the network connections that you may have at the office. Not terribly mobile, but pretty low cost. If you aren't travelling much, or will always be travelling to places where there are good phone connections, then a wired network should be fine for you.
A wireless network is just that - wireless. There are two main types of wireless data network; fixed point, which uses transmitter and receiver "stations" for coverage within defined areas; and mobile data, which is the data side of a cellular phone network. Read on to find out more about wireless.
So Which Wireless Network? 
Fixed Point: If your business means you need to send huge files between offices, buildings or cities, then, a fixed point wireless LAN or WAN is probably right for you. This is because you will need high data speeds. A service provider like Walker Wireless will come and set up 'hot spots' in your premises. This enables your people, while they're inside your coverage area, to access email and the web - or even access their network connection. As WiFi nodes multiply, fixed point wireless is likely to get more and more common. 
Mobile Data: If you need more mobility than than just around your workplace (in the car, on a building site etc), then "mobile data devices" connected to a mobile data network is probably better for you. There are only two mobile providers in NZ as yet - Vodafone (GPRS) and Telecom (JetStream). Though a JV of TelstraClear & Siemens looks like in getting into the market soon.
Both will cost you a reasonable chunk of change to operate, but Vodaphone's GPRS is great if you are sending smaller data loads and if you want to send & receive overseas; Telecom's JetStream is faster nationally for bigger loads (files over 1Mg). 
Next time we will look at some of the wireless gadgets that you can buy.

Daily Dilbert 

For those of you who love Dilbert, you can sign up for the "pay" Daily Dilbert at a massive cost of $10 per annum.
Just be aware that although the PR for pay Daily Dilbert promises you great wallpaper and screen savers, there is only ONE wallpaper and no screen savers that actually have Dilbert in them.
Go to http://www.dilbert.com/ to check it all out.

TLAs for SMEs

Here are this newsletter's TLAs for you;
  • WiFi, Wireless Fidelity. High-frequency wireless local area network (WLAN) technology, rapidly gaining acceptance as a wired LAN alternative (and home network). Wi-Fi is specified in the IEEEs 802.11, 802.11b, 802.11a, and 802.11g specifications using Ethernet protocol and CSMA/CA for path sharing
  • IEEE, Institute of Electrical and Electronics Engineers
  • CSMA/CA, Carrier Sense Multiple Access with Collision Avoidance. Network contention protocol that listens to a network in order to avoid collisions. High contributor to network traffic because, before any data is transmitted, it has to signal the network to check for collision scenarios & tell other devices not to broadcast.

Please feel free to email me with any TLAs that you want to get the bottom (meaning!) of.
