screen turns on randomly

Hi all. My screen turns on randomly when Im not touchin it. Is this normal? Havent seen a single evo thread with this discussion.
Seems like a battery drainer, although I will admit Ive only noticed it when its chillin on the charger.

actually i think i've seen it discussed before. I'm pretty familiar with my screen waking up when on the charger and it hits somewhere around 70-80% for some reason. It may be the kernel. I'm not sure if it's doing it with the new kernel i recently switched to, I'll have to pay attention while its charging again tomorrow or something.

As long as it only does it on the charger I guess its not a huge deal. Just worries me because my old windows phones screen would always turn on when a program wanted to update anything.

My phone used to not do this, or it took me half a year to notice, but my screen turns on randomly as well. Both when on the charger and when not plugged in. Very odd. As long as you have it set to turn back off it will probably not drain your battery too bad, unless you have it to turn off after 10 minutes or something.
This is kind of annoying - I was about to start a thread but found this one instead.

are you running a different kernel?

I have stock... yeah I know, I'm not fun.

I've noticed this happen to my phone a few times as well, only while charging though. It has always done it. Before I rooted, and I've seen it happen after rooting. I don't know what causes it, but I haven't noticed any adverse side effects from it. I would also like to know what causes it though.
I watched a story on the news a few months back, about people installing spyware on their significan other's phones, to record everything and watch whats going on through the camera! They said to beware if your screen turns on by itself from time to time! << haha, just tryin to scare ya! doubt it's anything to that nature. Just a quirk of sorts I think.

Random switch offs.

I've had 2 replacement phones in my 1st month of having a Gnex.
Just then I had a random turn off. Normal or not?? No rooting, no unlocking fully stock 4.0.2. Wtf?? I just thought yay!, everything is going to OK then bang. Not cool. Might be normal but I doubt it...
Thanks guys.

This happened to me last night.
I wasn't using the phone, it was just on the table charging.
Not sure what's up.

Do we have faulty units?

I guess it depends on how often it is happening.
I've had my phone for two months now and I believe this is the second time it happened.
As long as it doesn't happen too often and not during a ROM flash, I can live with it.

Yeah, that's the problem though isn't it. Random. It could be when your flashing a rom, or in a phone call. That'd be ****.
I dunno, why do these things happen?
Don't Google test things? Its not real stable is it. There should never be any problems if its a full release.

Do you notice if the phone is hot when this happens?

Nah not at all. Its happened twice since in had it. Once when the battery was at like 6% on its first run down of the battery when I got it. Then on it's first charge. It was at about 80% and I was just swiping left and right and I think bringing the notification drawer down (which doesn't work sometimes, I have another thread on that) and it just turned off. I pressed the power button a few times and it finally turned on with a 10% ish battery drop. That's it though, not again yet. May of been a battery conditioning thing.

[Q] CPU overheat and crash, help?

My wife's Epic 4G was working fine yesterday but today it crashed and overheated pretty severely. When it was still plugged in and crashing it showed the battery charging and then it turned yellow and show a yellow warning triangle with a thermometer beside it, is the phone going to stop working on us?
I would appreciate a quick response so I can take it to Sprint and see what they can do about it.
I just factory reset it to insure that it wasn't a rogue application or what not and the phone is still running slow, not as bad as when it was crashing, but it still works so I don't know what's going on with it.
Also the phone is stock and has always been stock without root or any other type of hacking, etc.
It just stooped working perfectly one minute.
She showed me that the screen was blinking rapidly in an up and down bar fashion on the home screen and during applications.

First of all how old is the phone. My phone runs games hot all the time and never crashes (well sometimes, but usually when im not even doing anything with it).
I would think that the video is going out on it and it is rebooting. Depending on the age I think your phone is dead dude.
Cheers

Not a year yet, it'll be a year old in June or July. I'm hoping it was just a virus or something because its working now. Should I exchange it anyway?
Nabbu eats your face.

Try flashing it back to stock or wipe the data if it isn't already rooted. I've never heard of anything of this sort... need some screenshots or something.

I already factory reset it and it's running right now as if it were just fine but what I'm wondering is if it's going to happen again and not work afterwards.
I'm thinking about taking it in to Sprint and exchanging it but I'm afraid there might be fees for exchanging or what not. The phone has been dropped multiple times but it never had any issues before.
The drop distance has been less then 2 feet every time.
No water damage to the phone itself but the Sprint tech said the battery's "water damage" indicator was activated and showing water damage.
The phone HAS been in the bathroom during multiple showers which might be the cause for the battery's damage indicator to go off but the phone, like I said, has never had any issues.
She downloads pretty much everything from the Market so I was suspecting viruses or malware and now it's "clean" it's running fine.
Any suggestions for where I should go from here?

The phone should be fine. This has happened to me a few times.... if your phone gets extremely hot it will refuse to charge as a safety feature and show that yellow triangle thing... open the back of the phone take the battery out and let it cool down.

Happened to me my battery got near 118*F so I took it out and let it cool on some aluminum and put it back in was fine
BTW you can't take a screenie because phone shuts it self off
Sent from my SPH-D700 using xda premium

I'm guessing that the overheating problem had to do with a buggy app that was running on the phone and took lots of data or cpu time. This has also been know to happen when running wifi hotspot apps.
Regardless, like everyone else said the phone went into thermal protection mode. The battery got hot and it wouldn't charge the battery until it cooled down.

Could be the screen being on and maybe running a governor such as "performance"? Also, I've left my phone under a pillow charging, woke up it was 110F and I haven't had this problem it mustve been really hot

THIS! ^^^ Without looking at your phone, I'm guessing this was the culprit. She had a buggy/defunct app that was probably frozen in the background while still sucking CPU/RAM. I've had a few of those instances and it DEFINITELY increases the temperature of the phone.
Only other thing I can think of is if she runs her phone at the brightest setting and has a long timeout on the screen timeout. Either way, I think it's nothing a little spring cleaning of the apps and tweaking couldn't take care of. Good luck buddy

[Q] Epic overheating abnormally.

Ok so my sister's epic is overheating most of times (This is why I stick with HTC instead). Even when you connect the charger and its not being used. Bought it from a seller on craigs and the phone is in immaculate condition just it seems that the Epics are known for having that overheating problem. Wanted to know if rooting would fix this issue or should I just take it straight to Sprint(even though the morons that work there, reset the phone and reinstall the stock software) And rooting would only void the warranty. Oh and the battery dies pretty fast. And the other issue is the Wi-Fi and 4G switches turn on by themselves? Sound normal to yall?

What does your sister typically use it for? I've been using mine as a primary source of internet for the last 2 years and it's been known to overheat while downloading for long periods of time (which is almost always). I download roughly ~80-120gb a month. I've never really worried about it overheating though because it just seems to sort itself out and when I check it a few hours later, it's warm/cold.
If the battery is dying a lot though, you might as well take it in to Sprint and have them run diagnostics on it just to make sure there's nothing physically wrong with it before you root it and void the warranty. Maybe you can get a free battery or something out of it just in case.

To get the 4g and wifi to stay off, disable the Sprint Connections Optimizer in Settings>wireless and Networks.
Every phone I've ever had gets hot on the charger, so please give us more details.
What is fast battery drain? Again, usage details needed.
I walk on toilet paper cuz I'm the s###!

Epics are not "known for having an overheating issue". I know that doesn't help your issue but I'm just saying because that's a completely false statement.

Thats HTC for you... it was a thunderbolt.... what on earth made you think it wouldnt get hot? ROFL!
Some low MA chargers under 700MA charge output make my phone hot, i use an aftermarket 900MA 5v charger.

Yeah, if I run my Nav program while plugged into a car charger, I have a tendency to overheat. Twice, the phone shut itself off and you get this weird icon with a battery next to a red thermometer.

Yes this is off topic, blah, blah, blah, but do you find that your battery percentage DROPS while plugged into the car charger? In both the vehicles I have regular access to this occurs. It doesn't matter whether or it it is going through a 140 watt inverter and a 750 or 1000 Ma charger or a 1000 mA USB port on my Bluetooth FM transmitter. It. Just. Drops. I can only get it to charge with the screen off and the phone in deep sleep. It's been driving me ****ing crazy ever since I got this refurb about a year ago and I think it even happened with my original Epic. I've just resigned myself to carrying 3 batteries with my every day 5 batteries for long trips. I don't get it. It's quite depressing though, plus my Epic will rape itself if I have navigation and TuneIn on. It might only last 10 minutes before freezing and rebooting at 120°. God forbid I add 4G to the mix. Am I the only one this happens to? I'm still pissed just thinking about it. Am I the ONLY one this happens to?

never happened to me it discharges sometimes but i turn off 3g and itll cool down, sure it gets hot, are you using SAMSUNG car chargers? they can help. and is your battery dead or eol? a dead battery can ruin chargers.

Yeah I will take it to Sprint sometime this week for sure. My sister uses the phone for simple web surfing and email checks. But mostly for call/texts. I think the issue is the battery most likely since it takes a lifetime for it to charge completely. My Evo 3D charges full in around 45 mins or less even when running at around 10% battery. And it never gets hot when connected to the charger. The other issue is the phone automatically turning the Wi-Fi or 4G switches by itself. Ive turned it off once or twice and 2 mins later its turn on by itself. Phone has been acting nuts. I've owned 3 Epic touches and 1 4G and they overheated when in use but never when connected to the charger. All my babies are rooted btw.

Well man I've owned 4 Galaxy phones all together and they all get horny hot from using them for simple stuff like talking on the phone and web surfing. That's why I'm sticking with HTC. Never have I had my Evo 3D get super hot with simple use unless I'm watching a movie or using the Wi-Fi tether. Maybe its the Samsung phones they sell in America lol we get the cheap crap.

Overheating has nothing to do with Epic or any other model. It just means she has so many things running at the same time. My friend has an HTC with the same problem.

My NS4G stays around 80*F its hotter than my Epic but I guess its normal for that even that its the same CPU.
But my NS4G doesn't get around 100*F while charging in my car though.
My Epic when staying asleep at my house it gets down to 55*F to 60*F. NS4G gets down to 77.

I don't make it a habit of checking my phones temp but I'm sure mines pretty low while sleeping also.. just sayin.. but when you're in a car, especially one that's been sitting in the sun all day, it is perfectly normal for your phone to get a little warm while its in the car also... charging or not for that matter. And then if you dnt have a working a/c... wow don't even get me started there.... lol but really all kidding aside, its normal for these phones to get 100 and even a little over that.. it all depends on how much is going on in the bacground while you are plugged in.... that said, everybody knows that every phone is different

[Q] Random power off issue

my epic 4g touch was on the cyanogenmod 10.1 wild for the night rom v. jan23v2. every time, if my phone were off a charger for 5-10 minutes the screen would flash to different brightness levels then turn off. it would do this every time since that rom. in order to fix the issue, i tried using sfhub's el29 root to go back to stock to try flashing the same updated rom. i was on el29 rooted and the issue still occured. i would have to plug it in for it to turn on again. is this a battery issue or is it something else? my battery is over a year old. any help would be appreciated. if you need more info, just ask

Amazon will have OEM batteries. Be careful though, some will label them like OEM but they are fake. You will probably be able to get a new one from Sprint or Samsung, though.

I've had good luck with cheap eBay ones for $3-$5. (~$10 for 2 + external charger, shipped from China)
Originally bought a cheap 1800mAh for my Epic, but kept it around and am using in my E4GT (when the orinal battery "puffed" and wouldn't hold much of a charge) Recently added a "2200mAh" one and external charger. It's a tiny bit thicker than my 1800, but still fits under the stock cover. I havent noticed the "2200" giving any better battery life than the "1800" - both work well and I've had no problems.

This issue is happening to me too but seems to occur when I'm downloading something like an MMS or app, or even an image intensive webpage. The screen flashes to different brightness levels and then the battery would suddenly "drain" to zero, where the software tells me it's at zero, but with a little extra charge and a reboot, the power level will be where it was before shutting down.
And none of this occurs while plugged in so I'm reasonably sure it's an old battery, I'd just like some confirmation. What gave it away though? The flashing screen thing had preceded a loss of signal so at first (and for about a week or so) I thought that was what it was until I found this thread.

Thanks.
When I went to get a new battery, the guy pulled the battery out and spun it on the counter. If it spins, it's expanded, and indicative of being on its last leg or already dead. Of course, you could also palpate the battery and you will feel the bulge but the spin test is simpler, definitive, and more entertaining. Just posting in case someone else runs into this problem or a similar battery problem and come across this thread - try the battery spin test.
