A few weeks ago I published a gadget diary post sharing my experiences with trying to get Qi wireless charging working with my Verizon Samsung Galaxy S3. Long story short, I ordered a wireless charging patch (receiver) and a Nokia DT-900 Wireless Charging pad and it didn’t work. One of our frequent readers (Haesslich) left a comment suggesting that the Nokia DT-910 Wireless Charging Stand might be a better choice… I took that advice, sent the DT-900 back to Amazon and ordered a DT-910. I’ve had a lot better luck with that one except for a couple new problems…

The charging stand itself is great. Instead of laying the phone flat, it keeps the phone standing upright. There’s a tiny white LED on the base, that is a little bright, but I just covered it with a piece of tape. There’s even a built in NFC tag that you can program to do certain tasks whenever you place the phone on the stand.
I bought the DT-910 to use on the night stand next to my bed. It along with the WakeVoice Android app I had found earlier, it completed my ultimate alarm clock setup. Or so I thought… Unfortunately, around 1am in the morning, I discovered a fatal flaw… Once the phone was fully charged, the display would come on and a beep-boop chime would signal that charging was completed. The sound wasn’t enough to really wake me up, but the light from the display did. After a several seconds, the display would automatically turn off, but then minutes later, I would hear the chime and the display would pop back on. This happened again and again and again until I removed the phone from the charger stand. Talk about annoying.
With the help of a couple apps, I was able to solve the beep-booping chime problem. But after hours of scouring forums trying to find a way to keep the display from turning on, I came up empty handed. I became more than a little obsessed with trying to find a solution for the screen issue. That is until Haesslich posted another comment talking about the fact that Android version 4.2.2 had some fixes for wireless charging algorithms. Our resident Android guru Ian Lim had been trying to get me to at least root my SGS3 for months, so I decided it was time.
After a lot more research, I found that rooting from a Mac is less than easy unless you have Windows installed on it too. I didn’t want to install Windows on my Macbook Air, so I ended up making a trip to Walmart last weekend to buy their cheapest laptop currently in stock at my local store – an Acer Aspire One for $268. I got it home and after a little trial and error, I had my Verizon Samsung Galaxy S3 rooted. Then it was a matter of wading through thread after thread on XDA and other Android forums for advice on which ROM to try first. I knew I wanted the ROM based on Android v4.2.2, and I settled on one called Carbon. More research was required to actually figure out how to flash the new ROM on my phone, but I finally was able to get it done last night… just in time for bed… and guess what? It worked!!!!!! No beep boop chime and no glaring display popping on and off! Problem solved at last! Thanks Haesslich! :)
I may try another ROM based on v4.2.2, now that I know how to flash, so recommendations are gladly accepted. But as is, I’m very happy that I can now use my SGS3 on the Nokia DT-910 wireless charger next to my bed and not have it wake me up in the middle of the night any longer.
Update 04/29/13 – I celebrated too soon, the nightly display turn ons started again a day or so later. It was suggested that I try Samsung’s official inductive charging back, which I’ve ordered from Amazon…
Update 05/04/13 – I received the Samsung charging back and last night I did not notice the display popping on in the middle of the night. It will take a few nights before I trust that it’s really working… But so far so good. Thanks Coco!
Update 05/06/13 – After 3 nights of not seeing the display turn on, I think the issue is resolved by using the Samsung OEM wireless cover. I’m not sure if it’s a combination of that cover and the v4.2.2 custom ROM (CarbonROM) that I’m using though. I like the ROM, so I don’t really want to go back to the stock ROM to test…
Update 05/16/13 – I just wanted to circle back and let everyone know that charging using the OEM wireless cover, the Nokia DT-910 wireless charging stand and the CarbonROM custom ROM is working flawlessly. I also have some info from someone affiliated with the Qi people…
Taylor: I also wanted to flag your most recent piece on Qi: Julie’s Gadget Diary – 2nd look at Qi wireless charging. The original wireless charging patch you bought (mentioned in the previous article) was actually not Qi certified, which is why it was not working. The WPC is taking action against such uncertified Qi products.
Julie: Thanks for that info about that wireless patch… After buying Samsung’s Wireless charging back, I’ve not had any more troubles. Are there any patches that are certified?
Taylor: Sure thing! Glad you haven’t been having anymore issues. Only replacement backdoors are certified. Patches are problematic because they tend to provide insufficient magnetic shielding.
