[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.

[Q] Note 2 just wont turn on

I recently bought a new note 2, and everything was good and I love it!
But yesterday I was on the phone to a friend and initially I tried putting him on speaker phone, but the screen wouldn't turn on, only the soft touch keys at the bottom lit up. I thought nothing of it and continued my phone call.
It wasn't until he hung up I noticed i still coudn't the damn thing on. So i removed the battery and re inserted it. Here's where things get interesting though, now whenever i try to power it up, i get a little red light in my proximity sensor (i think) that flashes for about half a second.
I've tried soft rest, which does the same thing ( makes the proximity sensor light up for half a second)
Hard reset which does the same thing.
I haven't rooted the phone or anything. Luckily its still under manufacture warranty and I'll get samsung to have a look at it, but any thoughts on what it could be?

Well, I can tell the that the red light is normal, I get that too and its just because its booting up, when you turn your phone on, what happens exactly?

Thanks for the reply. When I press the power button, around a second later the red light blips for half a second and turns off, but the OS doesn't boot up and nothing happens.

Maybe you too.... Sorry that sucks.
This PSA was sent Flow style from my Note 2 N-7100

Now i am really getting worriyng about this, does note2 has started SDS ?
atleast 3-4 cases are reported with same symptoms.
Anyway can you tell
You were on which ROM when this happened?
Are you getting to reboot in recovery/download mod?

@dingokevin I had a read over the thread you linked, and I fear the worst has happened to my note 2. This seems like a serious issue and even a flaw with the motherboard perhaps? Thank the lord it is still under warranty. R.I.P old friend.
@dr.ketan Im not sure what SDS stands for... Yeah I was running stock touchwiz 4.1.1 I think. No modifications and no root what so ever, and nope :/ I tried holding down volume down key + home button + power but no cigar, just the proximity light flashes briefly.

SDS - sudden death syndrome
And if you are unable to get into download/recovery mode then nothing can be done except send it to service station. it highly suggests sudden death which is very known issue for SGS3.
Replying to your query at other thread, you will get motherboard replacement if it is under warranty.

Ahh thats probably whats happened then. Thanks guys, I'll send it off to samsung and have a word or two with them to see why this is happening to many people!

If possible share outcome here too.

I was just reading up on some possible causes here on XDA with peoples S3's and someone suggested corrupted NAND memory.. I think this maybe the case because before the phone call I had installed Gangster Rio (which i honestly did purchase off the play store, hand on heart) and after playing it for a while decided to un install it and get a refund. Could me doing this have caused the NAND memory to corrupt? The game is a pretty large file...

I highly doubt it was screen damage, imho. I only received the phone last friday and have been cradling it like a fragile little baby, Its never been out of my sight lool.
Maybe i just got really unlucky and ended up with a faulty device.

If screen fault then in such case usually you can hear boot up sound. It seems your case very well fits to sds category only.

Hi Guys,
Got up this morning having left my Note 2 turned on and on charge overnight to discover this same fault -
slow flashing Red light and phone totally dead.
Unable to do anything to rectify the situation.
Still under warranty of course, phone only released in October 2012.
Is this a fault with the phone which necessitates replacement or just a battery problem?
Would be grateful for any advice / guidance / help.
Thanks,
Mike Longley.

It seems also like SDS send it to Repair AFAIK is a chip problem, not battery so you can't do anything to repair it. If it is under warranty and with counter at 0 send it. They must repair it.

[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!

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!
Sent from my SGH-T999 using xda premium

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?

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.

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.

Mirrored and upside down screen device after factory reset

I have an HTC One V that mirrored and flipped everything after I did a factory reset. So when it boots, it boots flipped and mirrored. Also the bootloader is flipped and mirrored. Before the factory reset everything was working fine...
The touchscreen remains normal. So it's almost impossible to tap the right buttons. Anyone that has a solution or at least a cause?

Well it's not mine. A friends kid got it from his mom. Don't know if it was dropped, but it was a used phone. The guy told me it was fine when he got it, but after a factory reset it flipped the screen. Don't know about the colors, haven't seen this HTC without this problem, so I only know it showing these problems. A few pictures of a normal one for reference perhaps? He didn't mention it was dropped.
It's not really important anymore, as the kid gave it back to his mother and he was promised a new one. A bit annoying, because he manages to break a phone a month and I get to try to fix them...

well the kid probably dropped it and it just took a bit for the display to go defective..

If it was really just after a factory reset you can try to RUU it but it doesn't seem that way. If he dropped it I don't think it's just a display damage it's more likely something on the motherboard. Or maybe the connector unplugged a little

In my opinion not old enough to have a mobile phone. But maybe I'm the one who is getting too old.

guys, I dropped my HTC one v today. though it was working well untill I did restart it for some other reason. . n den it started showing the same characteristics as mentioned in above posts. display flipped and mirror imaged. touchscreen working as if display is not reversed. so operating that cell is difficult. . ofcrs colour s also got messed up. exactly nsame issue as mentioned jn above post.. could anybody bfind solution for this ..?

You are not alone I have my secondary device (HTC One V) and thats too up side down and mirrored. I hope you have some solution for me. I have tried resetting and even I have change my ROM and recovery but not luck. So I believe that it must be some hardware problem. My phone was once damaged very badly and the screen glass is broken already.

If it's a hardware problem and everything is displayed upside down (the bootloader and splash screen also), you can't fix it completely by modifying software. But you can tell your display driver in the kernel to display everything upside down.
This doesn't fix the problem, it's just a workaround and your bootloader, recovery and splash screen will still be displayed upside down.
