Was the same for me, my screen is broken, and a fev little peaces missing from the lover-left corner, so a drop of water get in there. It looked the same, i just removed the battery, waited for a day, and plug it in. But it still was not ok,
so i checked adb logcat, and the rom was booted up, then i just keep on pressing the pwr button, to turn on-and off the screen, after like 10 try i got it working.
Dunno if i was lucky, or something, but definetley was from water!

This phones been on n off so many times already lol she spoke to a guy at orange and he said it needs a new carcus lol and if that I was to take it a shop would cost about 400 quid lol **** that was my response lol. Its just annoying coz can tell phone is working just can't see the screen arrrggghhh lol I wondered if reflashing it would work but she wouldn't let me root it so don't know how hard that would be lol

try to boot up the phone, connect it to pc, and type 'adb logcat' ( with droid sdk + usb drivers installed )
then you can see if the system is working, properly. imho its a hardware error, like the gpu, or between the gpu and the screen, so send it back if you have varranty, if not then its suxx
but a lot turn on-off solved it for me

I had exactly the same problem - and the solution was turning off / on like a hundred times. After a while it suddendly worked again! :victory:
That's actually not really satisfying, but the main thing is: my sensation got back to life!

i727 skyrocket stuck in continous reboot loop and doesnt get past start screen

I I have a Samsung Galaxy S2 Skyrocket i727 (with stock firmware and ROM), i dont have a SD card and not too many apps installed either, maybe 10-15 apps at most. Today while the phone was in my pocket it just went into this continous reboot cycle, it reboots, gets to the AT&T splash screen and then reboots again and then this goes on forever.
I googled the hell out of this issue but cant seem to find a solid solution and hence hoping u guys can help.
I cannot get into recovery mode cause it never gets past the splash screen
I cannot seems to perform a hard reset (power button + volume key) , it just reboots again.
I tried plugging the phone and connecting via USB but it doesnt help either, it reboots before the computer can detect the phone.
Hope u guys can help ? life without android is no fun...

I had this same issue with my LG Phoenix, I tried the needle around the power button, and that popped it back to normal. Apparently I held the button down to a side and it got stuck even though the actual button part was in it's "normal," position.
However it did reboot several more times after I got it unstuck. I did remove the back & battery, & unplugged it. Let it sit for a few minutes, after that I put the USB cable back in, then pressed the power button, put the battery back in and pressed the button again, and it went through the normal reboot process.

Just wanted to give you guys an update that i started cleaning the part around the edges as some folks suggested and that failed. then tried smacking around and blowing air into and that failed. Then took the entire phone apart and cleaned it several times using different techniques and sad to say that it all failed and i m SOL.
Bummer but it is what it is and i was quiet happy with that phone.

Where does one find a power button for the skyrocket (the one attached to the motherboard)? The closest thing I could find was this:
http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-ii-skyrocket-power-button-repair/
It is a repair service though and I live in Canada, I would prefer if I could just order that part. I have been to few repair shops that cant do anything because this power button is hard to find. I opened up the motherboard and the power button clicks fine, so I think it probably has to be replaced.

Freezing the phone
I had the same issue, came here and read all the things about the stuck power button and needing to replace whatever is beneath it. My friend works in aerospace and had told me about one of the things they need to worry about is temperature causing wire shrinkage due to temperature. For whatever reason, I decided to use that logic and throw my phone in the freezer wrapped in a dry rag. 30min later and the phone finally worked after 8 hours of the boot loop/no boot. That was around November and I haven't had an issue with it since (until today, but it is a different issue).

I have just fixed mine!!!!
There is a little battery on the circuit board when you take apart the phone. It looks like a small watch battery. Top side is and bottom side are opposite polarities.
I had the exact same symptom. Sometimes just pressing the power button momentarily would bring up the power down menu, then I knew to press it a bunch of times because it was stick. If I didn't eventually it would turn off and vibrate constantly. It kept getting worse.
I measured with an ohm meter and the button itself seems fine so I figured maybe the digital logic relating to the button itself is faulty. So I shorted the little battery on the board (do this only for a brief period, no more than 1s) and put it back together.
Its behaving perfectly normally. I was also getting weird artifacts during video playback before, kind of like what failing solder would do on a bga gpu. It fixed that too.
So I think its similar to that problem some laptops have, where it wont turn on until you remove the battery, hold the power button down a couple times, and then plug it in. It seems a complete circuit discharge fixed this problem at least for me.
If people are interested I can try to find a picture
removed link
In that picture its the silver shiny metal circle. To short it you connect the bottom soldered part to the metal plate on top of the battery. This comlpetely drains all circuits.
So I think a lot of these problems are caused by a phantom charge. In any sense, Im very very happy
Also this could explain why the fridge method worked. Cooling the battery can significantly drop its charge, however I would advise against the cooling method if possible.
EDIT: blah cant post links... if anyone needs the image pm me your email

You'd need to find a friend or local electronics repair shop, but I ordered some here:
http://www.etradesupply.com/oem-samsung-galaxy-s-ii-skyrocket-sgh-i727-power-button.html.
The buttons are $0.99 USD if you buy 2 or more ($1.05 CAD), but 5-7 day business shipping is like $16.99. Still cheaper than a replacement phone, and it's an easy fix for an electronics person or electronics/tv/computer repair shop... At the rate these power buttons have had reported failures, and for the price, I'd get a couple of them in case the replacement fails in the future...
If my wife keeps squeezing the power button on her phone when some crappy app she has wigs out, I'll be needing my second button sooner rather than later...

why when one person says it something everyone band wagons on that idea. i actually had the same issue my skyrocket couldn't go pass the "samsung" screen. all i did was flash a new rom or i just restored an old backup

Then it was user error or a bad flash. And that's software, not hardware.
Skyrocket power buttons are known to fail. I believe Samsung has even acknowledged this.
When your phone randomly goes into a 1-second vibration cycle, sometimes showing the reboot menu beforehand without pressing the button, more than likely it's the power button that has either failed or is sticking.
With my wife's phone, the button was not sticking, and usually lightly tapping the phone at the right angle on your lap or the counter would break the vibration cycle and let it boot up, until the next random power button press and vib cycle would happen.
Button replaced, same exact ROM, and problem gone. :thumbup:

I have a repair shop and i fix these issues with no problem. the only issue im located in Puerto Rico. when the power button gets stuck is because of heavy use, a fall or something that makes a lot of pressure to it and the copper contacts inside the button stay making contact. this is know to happen to i727-i717-i997-i897 and some other galaxy s1 s2 models.
i attached the picture of the power button.

dead backlight and possible backup solution

hello GS3'ers my brother has some gs3 problems
his gs3's back light appears to have died out. he can still use the phone just can't see what is going on, the sounds still work and everything. has anyone come across this before? i told him to hold a flashlight to the screen so he's able to backup his pictures and what not but the screen is really black. which is his main concern right now, because he wants save his things and then return the phone if he has to.
any help is much appreciated, thanks!

My understanding of the GS3 is that since it is an AMOLED screen, it does not have a backlight. Each individual pixel emits light. My guess would be an app is causing the problem, possibly one that alters screen brightness. I would start by pulling the battery and restart the phone. If you see a boot animation, your screen's not dead.
Sent from my SCH-I535 using xda premium

that makes sense because the flashlight thing didn't work. he restarts his phone and even the boot logo is happening during a pitch black screen but the sound could be heard. it's gotta be something more serious

Nexus 5 screen died today + dangerously hot lower screen

Went to unlock my phone this morning off the charger and the screen is totally dead. Couldn't unlock or do anything to it or even see what was going on, called Google and ordered a replacement ASAP.
Went through the not fun task of doing a nandroid backup without seeing what was on the screen and doing some trickery with screenshots then backing up my entire SD card.
However, here's the strange and potentially dangerous thing that I noticed later when I got home this evening. I went to look at the phone and go to a fastboot flash with the factory images and went to touch the bottom of the screen. When I went to do so, to the little bit of the left of the LED light was a SUPER hot portion of the phone. I almost burnt my finger it was so hot.
Not sure what to do about the issue, I feel like if I just call the support line they won't actually take in my concern legitimately. Any suggestions?

thats something quite strange
let us know what google says about RMA and this issue

Agree, maybe it's just your phone, maybe it's all the batch. Which batch/model do you have?

On my Transformer Infinity, sometimes the screen won't turn on at all. On a few occasions, if I press Power enough times, I get a glimpse of a message saying the Launcher process has stopped, but then my touchscreen doesn't register any input. The tablet is also sometimes running quite hot at those times. The only way I know to recover from this is press the Power button long enough to force a reboot, then everything is normal. Could this be what's happening? Do you know if the phone is still running under the black screen? Have you tried forcing a reboot, and did it work?
As for the hot phone, I've noticed my N5 does get a bit warm when I'm using it intensively (4G, WiFi, Bluetooth, GPS and screen on all at the same time and in use) but not enough to burn me. Could be hard to tell which component is heating up like that since I think it could be the screen backlight, SoC or battery... Do let us know if you find out more.

I had called them and reported the screen totally dead with lines streaking vertically and got a new replacement ordered. It wasn't until late last night when I got back and had the screen on in this dead mode that the bottom was extremely hot. I'll have to call them back and let them know

Yeah, no its definitely dead. There were streaked lines across it, rebooted it multiple times. I ended up going into the bootloader and recovery via adb/fastboot and all that jazz. It eventually just would not work now.
In regards to the hot part I definitely think it was the lower part of the screen. It was quite literally half an inch away from the LED to the left. Was super super hot then once I shut the defective screen off (I could tell by the backlit light or whatever) it wasn't hot anymore after a minute or so.

Is it black/white? 16 or 32? When did you get it?

32gb black version. I ordered it immediately when they announced it that day.

mine gets really warm when i'm doing a TWRP backup then it goes into bootloop after and wont cool down. i have to force it to power off from recovery and let it cool, but i've always seen it happen. i wonder if yours was attempting to boot over and over for hours and cooked itself.....? i have a launch day black 32gb too, running Cataclysm with Franco at the moment but it was doing it on rooted stock with stock kernel

I had to send my 19 day old 32Gb Red Nexus 5 in to LG for the same reason. I was using the phone and all of the sudden had vertical lines and the bottom of the screen got burn your fingers hot. Waiting to see what LG does with my phone. The only thin I can figure is the synaptics chip which controls the screen is bad. Its the only thing in that area that could get that hot. I also noticed when I first got my phone the glass in the same area looked like it had a slight wave in it. Didn't think anything of it at the time. I'll let you know how it goes.

Is RMA/replacement applicable for Rooted and unlocked devices?

I don't believe its an issue with developer phones as long as the issue wasn't caused by something you did like brick it by flashing a wrong radio or something like that. It has to be a manufacture defect to get it fixed for free.

Update or bad screen?

Hey people
Got my smart watch about 4 days ago and it was all good until tonight and now for some reason i can't see the clock anymore unless i press the power button :S i could have sworn it had a low light mode and the clock was visable ok but since tonight i can't see the time unless there's a light pointing straight at the watch. I hooked it upto the service centre thing and updated it through that but hasn't helped.
am I going mad here and just seeing things? :S
EDIT: i also noticed when i turn it off i get some weird colours appearing in the clockface some pinks/purples. i don't understand it was ok a couple of hours ago and it's been on my wrist the whole time :S

Did you try to reset the watch? Also our you have any custom clocks installed, remove them. As after reset, Sony smartwatch app will reinstall them on the watch, once the watch and the phone are connected.
On your watch, go to settings and tap reset watch.

Just to make it clear, you are not talking about the low power mode right? No backlight, but can be still seen by people in ambient light??? Maybe you should take a picture of the watch so we can clearly see what is going on.

At night my sw2 turns of the screen completely. But when I MOVE the watch it turns on the clock on the display. I think it has an accelerometer that turns off the screen when no movement is detected.

The same for me. I think that isn't a bug, but accelerometer

It is normal.
It is a feature to save battery when it isn't worn.

I am more curious as to the "watch (display) turns on from moving it". Does the SW2 have an accelerometer? My watch display doesn't kick on when I move it. Or was this a feature of the earlier SmartWatches?

I believe SW2 does have an accelerometer. Put your watch on a table, leave it untouched for while, screen completely turns off. Not even the low power watch mode is displayed. But once you move it, low power watch comes back on (without the backlight). I observed it many times when it was charging and when left at the bed side table.
But it is not utilized for backlight function. That is a missing feature people are asking for. But I don't really need it. Just like a regular watch, I press a button to turn the light on when I can't see it in the dark.

Wow... I didn't even notice the screen going completely black after sitting for a while. I am still on watch honeymoon, and either the watch is on my wrist or turned off and on the dresser. But sure enough, it does go into a deeper "sleep" mode and wakes up when I pick it up. Nice!
I do see that having it wake to the backlit mode would be nice but it would seem to kill the battery since when worn it would be in more constant movement. Unless they tuned the accelerometer to only wake when a more significant motion happens.

Yeah the previous iteration of smartwatch from Sony did not have always on watchface and it was a necessity. And to see the time you had to turn on the display. One way was to double tap on the watch screen to wake it up. Another way was to light up the screen by lifting your arm and turning the watch towards you. But the second way never really worked reliably.
But I don't think SW2 needs that. As we already have always on watch with great readability even in places where there little light.

So there is nothing on the screen not even the low power mode on the watch. I don't know what to tell you boss as you have already done a reset. Maybe one thing to check is to use SUS to reflash the firmware using your pc, if you haven't done it already.
