[Q] Extremely weird screen behaviour.

Hello all! Ive just recently got my Xperia arc, and flashed a nightly build of CM7 on it, number 20. Everything seemed to run smoothly, but just now screen started to behave very weird, it almost seem to have osme kind of "ghostly" second touch.
The upper part of the screen is almost impossible to use, when I try select an app to move it on the screen, by holding finger down, it just flickers for a second and gets deselected. If I manage to select it and drag+hold, it starts spazing out all over the screen, with screens switching between eachother by it self.
The problem is especially noticeable in games, where you usually have a joystick controller in bottom left corner. When using it, I usually trigger the buttons above it in the upper left corner which I am no where near at with my finger.
Is this a ROM issue, or hardware issue? Ive been using the rom for couple of days with no strange to it, and now this happens. Any ideas what the source can be?

ROM failure.

Sorry for bump, but apparently the problem remained. I changed to XDA rom, which too is based on CM7 thou and after a day I stumbled upon same problem of ghotsly second touch on screen.
I cant hold to move apps, cant precisely press a button in game on left side of screen, it then triggers some other button nearby. I do get haptic feedback from long press on a homescreen, but the "add new" menu popups only every few tries Any ideas of what may be causing this? I would really like to avoid the hassle of resetting the phone and sending it back for repairs :/

try stock one or miui.

It sounds a bit like your screen had a bad encounter with water...
Could this be the case?

No, this phone is only few days old.
I think I am noticing a pattern.. screen behaves this way only late evenings, till next morning. I never noticed the issue during the day, but then it was there again for no reason after I left phone for couple of hours (it's past midnight here at the moment). Now when I think back, same was previous two evening, issue only noticeable during late evenings. Could my phone be possessed lol?
It's quite weird issue too. Upper half of the screen seems to have a ghost touch as I said. When trying to add a widget to upper screen, I only get a haptic feedback from long press. When playing games, all buttons on left side (landscape mode) get activated as soon I press one of them. Most weird of all, is that screens works perfectly in app drawer and settings, but not in app/homescreen. I will test how it is again tomorrow and report. If it works just fine again as if nothing happened I will be really puzzled.
Currently on CM7 Xda version, same was for official version. I am considering updating to MIUI, just gotta figure this radio difference stuff, but am becoming sceptic to whether this issue really lies with ROM and not app/settings.

Yep, issue is gone like nothing happened at the morning, this is is haunted ._.

I've figured the cause, it only happens when the phone is plugged in and charging. Beats me why thou, what remains to see now is if it is tied to the kernel or not. Posting it here in case others with similar problem stumble upon the thread.

Are you using the stock charger, i used to face bit similar problem when i used to connect my old HTC USB charger... later i discover the HTC charger was giving only 500mA , where as sony one is rated at 700mA.

Thanks for the tip! Turns out it didn't like my 1000mA charger I am using for all my usb stuff, but the stock on works perfect (it's 850mA).

Button Problems and First Root Ever

Hi, Everyone! This is my first post on here but I have spent the better part of the last week reading all the different threads. Yesterday my Samsung Epic 4G decided to go a little insane on me. It was working eprfectly fine (especially for a 2 year old phone) when all of a sudden my power button seemed to start cyling and the power off screen kept popping up and the volume keys did the same. I turned the phone off and even tried taking the battery out and giving it a rest but the problem persisted.
Another issue was that some of the numbers no longer worked correctly. The even numbers both on the touch screen and keypad would dial
"2468" instead of the corresponding number; very weird! The phone had never been rooted or modded at all. Well I was able to get into the phone after figuring out a way to input my passcode with the faulty numbers and I performed a hard reset. The phone is back to completely stock but the power button and camera button do nothing. The volume up button works well but the volume down (besides lowring the volume) button causes google search to pop up and then a bunch of letters and numbers to be typed in both the google search bar and in the message of box of the last person I texted. I can still use the phone by opening the key pad to wake the screen up and I can text and call fine as long as I don't touch the Volume Down button. Also, battery life is ridicolously low. I am up for upgrade but don;t really feel like upgrading to the S3 just yet. Sorry for the long post. I know it is against forum policy but I wanted to get the whole story out there. So here is what I am looking to do:
I want to root the phone and install one of the roms to maybe eek out a couple more weeks out of it. Again it works ok now, just the sliding out of the keypad and lack of power button sucks. The phone boots up if I take the battery out and put it back in wihtout touching the power button.
I have read up on Odin and that looks somewhat straightforward. Just trying to see what you think is my best course of action. Again, I do not have a power button working or camera button and a faulty Volume Down Button. Maybe I can do the whole slip in the battery while holding "1" to get it into download mode? This will be my first time rooting a phone so any help is great and appreciated. Thanks and again, sorry for the really long post!

I forgot to mention that the phone is currently running on Gingerbread 2.3.6. This may or may not make it more difficult to root.

Did the phone get wet at all? Use it in the rain?

was thinking this as well

It actually got wet about 1.5 years. I threw it in rice for about a week and never had any issues. The phone has never frozen or had issues the past year and a half. Yesterday it was in the kitchen charging (with a samsung charger but not one for this phone specifically) and it started doing the whole power button/power off screen flashing. I was able to get it in download mode earlier today but i don't know about recovery mode since the power button is dead. Maybe I should root it to see if its a hardware issue?
Edit: I forgot to mention that the phone gets really really hot while charging as well in the area above the battery. Hopefully nothing short-circuited.

It could take a while before the corrosin gets bad enough to affect your phone. I dropped a phone in the toilet once, and it was over 2 years before it crapped out. Took it apart and it looked like an old Chevy wheel well inside.

That is a good point. I never thought of that. It was also in the kitchen which was humid and hot as ever yesterday. Do you think any kind of root or rom could help me squeeze a little bit of life out of my old phone.

Doubtful. If you're hardware's screwed, so are you.

So I left the phone alone for a couple days with the battery out. I go to turn it on today and it worked perfectly. Then after about 5 minutes the power button stopped working again, but everything else is ok. No random letters and numbers and the volume buttons work as well. Now, I'm kind of lost as to what to do. I do have a parts phone, same one as this. Maybe I need to replace the power button? It clicks and everything and even worked for a couple minutes but now is non-functional again.

R800x bricked, please help

It seems I bricked my Xperia Play. It was working fine one day when it shut down due to low battery and wouldn't boot back up. I'm out of warranty, so tinkering around in the hardware is doable, I just don't have the tools at the moment. Anyways, with the battery in when I hold down the power button it vibrates roughly every two and a half seconds, but the screen stays off and the notification light stays off. Yesterday I was trying to make it boot, and I believe when it was connected to a PC, Windows defects it then it disappears when I hold down the power button, as well as the notification led blinks red/orange a couple times. Unfortunately I had to cut my troubleshooting time short(Rush concert ftw), so I was unable to do much research. However, I did a little and all the things that I found said that it was infact a hardware issue that requires manufacturer fix. Seeing how that's not possible I came Here hoping that one of the geniuses at XDA could help me. Help?
For the record its not my phone anymore, I gave it to my sister and she had about a day of use before it broke, and before they I let my friend borrow it so I don't know what she did with it, but she's fairly trustable, so I don't think it was something she did.
For those wondering my current phone is a broken Galaxy Nexus. Don't worry, I'm ordering a replacement tomorrow,

[Q] Rebooting and Power Issue

My phone seems to have some kind of issue. Starting this morning, my phone rebooted twice without me doing much of anything to it - I clicked the power button to check the time, and doing so caused the phone to reboot. I waited for it to reboot, and when I clicked the power button again, it rebooted once more.
Now, whenever I click the power button, the phone won't wake. I can wake the phone and use it normally by pressing the volume keys, but I can't put the phone back to sleep. My phone is still randomly turning off and rebooting as well. Right now, it's off and I can't turn it back on because the power button isn't responding. I have to plug it into the computer/wall to actually turn it on. Does anyone know what's going on?
At first I thought it was a faulty power button, but I've no idea what to think now. I'm running Calks E4GT 3.
For the time being, I'm using Smart Screen Off, which is working great. I can live with this, but my phone is still likely going to reset, and I have no idea why.

I'm no expert but when that happened to my phone I had it replaced. Turned out to be a faulty power button...

I was thinking about it, but I'm certain it's out of warranty. My contract expires this November, so I'm really hoping that's not the case.

It's your phone a year old or older?
Do you still have the original battery?

It is. I've had my phone since November 2011. I do still have the original battery, though the battery is pretty much shot. It had overheated (it was charging underneath some comforters), but a few days later the battery came back on, and I've been using it ever since. I'll get a new battery, but do you think that's what the problem is?

You can definitely try changing the battery, but also if you have insurance on your phone you should be able to call sprint and have them exchange it. I did it not too long ago and I had my phone since day one. I'm positive that my warranty was expired but I still had insurance on it. They sent me another one 2 days later.

I would definitely say yes, you need a new battery!
Amazon is your best bet. Anker makes a good battery.

How much did that cost you? I might have insurance on it, but I have no idea. I remember replacing one of my previous phones and it costing $50.

To be honest they didn't even charge me..lol. All I did was call sprint, told them that my power button wasn't working,they asked if it had any water damage. I told them it didn't and she asked if I had insurance,told her I did and she simply said no problem, asked for my address and said you'll have another device in 2 to 3 days. Received it in 2 days returned the other one no questions no fee..

I'm most definitely sure it's your power button going broke.
Battery issues usually make your phone flicker like auto brightness is adjusting before shutting off. And so on.
A battery issue wouldn't make your phone reboot by itself when touching the power button.
My friend use to have power button issues like what the OP stated. I told her, her case is causing it(she had one of those cases that block the power button and volume button with rubber) we took the case off left the phone alone for a day and the power button worked correctly. I since have cut out the rubber to her case.
Sorry about the long post
I've known 6 ppl with the E4gT in the past 3 months that have Power button issues. I usually can spot them now.

Seems a lot of people are having power and battery related issues. I've had my e4gt for around a year and my battery is going out. Had 2 ordered today so hopefully no more problems. Lay your battery down flat on the table if it's bulged or misshapen then it's bad. They're only like 10 bucks on ebay.

Sounds like what Im experiencing is the power button issue as welll; phone wakes up on and off by itself, power button doesnt always wake up or put the phone to sleep (or brings up power menu), and random reboots. So assuming this is the case for me too, and with insurance, will I have any issues trying to get it fixed if my phone is rooted? Or just make sure I have unrooted my phone and made stock before I take it to Sprint and Ill have nothing to worry about it then?

It is always best to go back to stock. They will likely charge you $50 for it though so it is actually cheaper to go to http://mobiletechvideos.mybigcommerce.com/samsung-epic-4g-touch-power-button-repair/. No need to go back to stock with them and they do great work.

I believe my power button is going out too. It does the rebooting cycle like others have mentioned and simply rubbing my finger across the button (without pushing it) will cause the phone to turn on and off.
I currently don't have insurance on my phone. Sprint sent out an email a couple of weeks ago about Insurance Open Enrollment. Anyone know if I can enroll now and turn around and take my phone in for repair (unrooted of course)?
Thanks

There was a thread on the power button issue on the Sprint.com forums, and a poster claimed he didnt pay anything for the repair and didnt have insurance (I guess because its apparently a known/common issue now). I figured with the open enrollment it might be worth $8 just to make sure Im covered, although apparently you have to wait 3 days after you signup (Jesus waited 3 days, so I guess I can too huh?). If its a known issue with the phone that is apparently at least somewhat common, I see no reason Id have to pay $50 to have it fixed.

****. This just started happening to me this morning. Phone was working just fine. I am just running stock rooted and now seems like everytime i try to turn off the screen the phone reboots. I have never dropped this phone. I dont have any insurance policy from sprint. Do you think there is anything they will do with this phone?

My reboots started happening earlier this week. I'm running the JB GB08 rooted leaked release. I called Sprint this morning and added the insurance coverage since open enrollment runs through the end of March. I plan on taking the phone into Sprint over the weekend after I reinstall the office ICS release build.

Soft-Bricked? Maybe?

Hi all,
I'm having trouble with my Telus Samsung Galaxy S2x. I was coming home from work on Wednesday and was listening to music at the time. I turned on my phone, went to text messages, the phone makes a really harsh and nasty noise (the music cutting out) and the phone shuts off. I instantly took out the battery and turned the phone back on again. It got to the boot screen and then rebooted itself and started to vibrate in 2 second intervals on a black screen.
I did some research and it seems like it could be a power button issue? The phone thinks you're turning it off and on again in an infinite loop. At first, I thought it was a battery problem (it still can be without testing a new battery) but I took out the battery and tried turning it on with just the power from the wall, and the same thing happened again. I have however, been able to get into Recovery/Download mode for about 2-3 seconds before it reboots and vibrates. There has also been times where I got as far as into the OS on the lock screen before it rebooted. For the most part it's usually gives up on the boot screen. I should probably note that I'm not a Telus customer, I bought the phone through a friend that worked there and used it on Wind.
My phone is rooted and I have Slimbean 3.0 installed on it - if that helps at all. I was wondering if anyone else had the same problem as I do and what they did to fix it. I'm not too too concerned about the phone (in terms of getting it refurbished). It's the data on the phone that I need to recover if getting it refurbished is my last option. That being said, I am running out of options and any help is greatly appreciated!
Thanks guys!

It is indeed a sticky power button issue. You can get it replaced or u can try to unstick it urself. Don't know where or how much. Try a needle to clean around the outside of the button. Try to rub alcohol to dissolve residue. Try to leave the phone off and water protected while in the freezer for 20-30 minutes and hope for shrinkage that'll loosen the power button. Weird but I heard it worked for someone.
