[Q] Strange screen behavior

Sometimes the screen of my Galaxy Nexus freaks out; it behaves as if I'm touching the screen repeatedly while I'm not. It does not happen a lot, but I think it mostly occurs after pulling down the notification menu and touching a notification message there.
I have tried to reproduce this behavior (camera ready so I can video the screen of my GN), so far no luck. Anybody else experienced this?

Of course, as soon as I'm in bed and have put my camera away I experienced the issue again.
Will try again this evening.

That really sounds like a faulty screen I'm sorry to say. I had a similar issue with my HD2 two years ago, had to send it for replacement.

Hmmm I hope not. Since it's very hard to reproduce I doubt I can prove it in order to get a replacement.

It happens to me only when I'm charging the device. Do you use custom ROM? I'm suspecting that right now.

Nope, stock rom. I haven't even rooted it yet.

Finally caught it on video! It's not very focused but it clearly shows my problem.

I don't think its a hardware problem because I'm mostly experiencing this problem at home. Today at work I used the phone the whole day without encountering this behavior. I'm 15 minutes home and the problem pops up again. Difference? At home the phone is connected to my WiFi. Any thoughts?

Does it happen when you're not holding the phone? I've had anomalies happen before when the phone is on table and not in my hand before. Or could be faulty driver for touchscreen chip.

No, it does not happen spontaneously. I happens when I'm using the phone.

I've read some threads for other devices concerning exact the same issue. There were opinions that it could be due to the static charge that gathers on the sensor.
Possible solution could be:
1) discharge the phone
2) remove the battery and wait for about 10-12 hours.
Try it may be it ill help you.

The phone has a stock image. Also it's not rooted and I haven't touched the bootloader either.

Back button defective?

Hi all,
Not sure if anyone is having the same issue I'm having. When I hit the back capacitive button once, 30% of the time it'll register 2 backs with 2 vibrations. It gets kinda annoying cause sometimes it'll get you out of an app if you it back twice. I called Samsung tech support and they told me it's a software issue and they can fix it out I pay$49.99. Their tech will remote access my phone and fix it on the spot. I just don't understand why I have to pay since my phone is still under warranty. I had this issue since my phone was brand new and stock but didn't complain cause I didn't think it would bother me but now it's getting annoying. Anyone had this same issue, and knows how to fix it?
Thanks in advance!

[Q] Phone will shut off own it's own

Hi I have a galaxy s3 running the liquid smooth rom, and I think I have a power switch problem. Yesterday I woke up and pressed the power button and the phone just powered off. Now my phone will shutoff as soon as it boots up. It will only take 10 seconds for the phone to turn off. When I take the battery out and put it back in, the phone will boot on it's own. I took the phone apart and removed the power button to see if that was the problem and that didn't solve it. so I believe it's the actual power switch on the motherboard. Anybody know a fix or if I am giving the wrong diagnose.

Are you rooted? Try to flash a ROM to see if it may be a software problem. Unless the power button is stuck on the pressed position, which shouldn't be true since you checked it. Let me know how it goes!

Sounds like you're on the right track. Not sure of a fix though, sorry. Warranty? Insurance?

lol no warranty or insurance. I think I'm going to have to find someone who is skilled enough to put a new switch on the motherboard. If I do fix, I'll people know. I see people have had this same problem and thinks its the Sudden Death Syndrome and it's not. Maybe I'll make a video or something if it goes well

I'm pretty sure the sudden death only affected the international models on esrly firmware builds.
Looking forward to hearing if you get it fixed! Good luck!

1st possibility: power button got stuck
2nd possibility: sudden death syndrome (but I think it can be lesser possibility 'cause SDS was fixed from Android 4.1.2 version and only international Galaxy S3 models has SDS possibility,so if you use international model you're on the wrong forum, if not I doubt that it can be SDS )

[Q] Odd brick situation Tmobile SGH-T999 (Cant find exact answer)

Hey everybody,
I rooted my phone a couple weeks ago and one day it just pooped out. I researched a bunch on google etc and found some things to try but so far no solutions.
Model: SGH-T999 T-mobile s3 (Used CF-Auto-Root and Odin for rooting)
Problem: After the phone pooped out, I was unable to enter recovery mode. I could enter dl mode however it crashes at variable intervals. So I bought a jig figuring maybe that would help but it still crashes in dl about 5 seconds later. Any suggestions?
Everything that I have found on the internet has been were people can usually get it into dl mode and keep it there or they cant get there at all even with a jig. Any help would be appreciated. Thanks!

If you were running stock it's probably a hardware problem. If not what Rom are you on? What/when/how was your most recent flashes?
Have you tried kAsp3rd's brick fix in dev section?

I just tried the kasperd brick fix and it didnt work. It still crashes at variable times and I cannot get it into download mode long enough to do anything. I tried a jig and it also still crashes. Any help would be great. Thanks!

Does it turn off? Reboot? Freeze?

It starts and then crashes. After awhile it might make it to the animation with the blue wave forming around the words samsung, but usually it crashes on the Samsung Galaxy SIII logo in the beginning. Also when I put it into download mode it crashes anywhere from 1-5 seconds after. When I try to get into recovery mode it crashes almost right away when the blue words are at the top left of the screen.
Also when I put the battery in it tries to boot on its own without me pressing power button, and sometimes it tries to reboot after it crashes and turns off without me pressing anything. Also after it crashes I usually cannot just press the power button to try and power it up again so I have to take the battery out and put it back in.
When I was doing the Kasperd brick fix I used the T999 debrick image. How do I know if I have a different variant of the T999. I saw that some people had T999v and T999N. What are those?

Look under the battery for your model. Sounds like a power button issue. All I can say is try fiddling with it a bit. May have to open to see if it is physically always in contact, or it could be a deeper issue on the board. Hard to say.

Ok I just see T999 on the label.
How can it be a hardware issue when I never dropped the phone or anything. I was just thinking it was because I rooted the phone because it happened about a week after I rooted it. It was working one minute and then a couple hours later when I took it out of my pocket it was off and I tried turning it on and all that stuff started happening. I will definitely check the power button though. Thanks for the help.
Also another piece of info to add. When I plug it in to charge both the battery charging symbol and red light will sometimes turn on and then it crashes/goes black similar to what happens when trying to power up the phone. Not sure if that helps at all. Thanks!
If my phone was hard bricked I wouldnt be able to turn it on at all correct? Im trying to figure out if I will need to get this thing jtagged or something in order to get it working again.

Physical damage is not a prerequisite of hardware failure. Ever have a hard drive go bad? Did you drop it first?

True, however I just find it odd that I rooted the phone and a week later it happened. That is why I am leading towards an issue involving that and not hardware damage.

If it was a problem with rooting, it would have gone south right away. Many people are having these button issues recently. And you don't have to drop it, like aerowinder said, but you do use the button right? Moving parts wear out. Hardware fails. That's really all there is to it. While I could be wrong in my diagnosis, I don't think that will prove to be the case here.

It does most certainly sound like a hardware issue in the power button. I read another thread very similar to this same thing on the T999.

Any suggestions on what to do from here? I dont think the phone is under warranty anymore.
I took the back casing off to see if the button is getting stuck or anything, but all the mechanics look normal.

I would recommend searching around for others who have had the same issue and seeing what their resolutions were. I've not seen many on here but google turned up quite a few.

Thanks guys! I found a good thread on here about the S3 sudden death thread. Im going to read up on that and see what I can do. It was just tough to find since I was thinking it was bricked but the descriptions for this power button sudden death thing sound spot on. Hopefully I will be able to get everything back in working order.

[Q] My Nexus 7 doesn't turn on or charge

Hello guys.
I wanna start saying that i found a couple of threads about this issue but none of them was about the 2013 version of this tablet.
Two days ago I was on a plane to London, i turned off my Nexus 7 2013 (the device has at max 3 months and i bought it brand new) that was fully charged.
During the flight I didn't turn it on...when I was at home, approximately 3 hours after, I tried to turn it on without success...tried to recharge it but no response from it...no blinking or steady white light.
Till now I still can't figure out what happened to it considering I just turned it off normally.
I tried all the steps provided by several google official support pages without luck. I also opened the back cover too see if some connectors were not properly attached; no problems there.
I am really starting to think that something broke.
My question would be: I bought it directly from Amazon and I was wondering if it's a problem that I rooted it and I installed a custom rom on it. Is it possible that sending it back will result in having it back myself without any kind of repair attempt?
Thanks to everyone will give this some time

Have you happened to try booting it into fastboot regardless of it not actually starting up? It's a long shot but you could try it.
Also if Amazon can't turn it on either it shouldn't be a problem.

By fastboot you mean the procedure where you have to press volume down + power button?
Anyways i kinda tried everything, it just doesn't respond.
Altough what I noticed just yesterday was that if I plug it to the charger it gets warm on the back, upper part meaning that the power still goes through...
But thinking that this is something related to the battery doesn't feel right...it was fully charged when I turned it off the last time.
I think i should give it back with RMA...It feels like the only choice i have.
