Screen died I think.

I have an old s2 sgh-I727r and the screen toned out and it won't come back on. It still works but no screen. I can feel it vibrate and turn on, also works fine on mhl if you use the screen for touch and watch the screen on the tv. Has anyone seen a oled just crap out like this? If I replace the screen is there a chance it could be something else. The screen is a $112. So want to make sure it is the screen.

Bad Proximity Sensor?

Is anyone else having an issues when on a call to someone you take it away from your ear and look at your phone and the screen doesn't come back on. I have to hit the power button to make the screen wake up. I'm all stock (4.4.2) with unlocked bootloader. I m trying to see if this is a hardware problem where I need to RMA or software problem.

Mine works perfectly well. Are you sure you don't have anything that might be affecting the proximity sensor, like smudges or a screen protector?

No, I don't have any screen protector not any smudges. I saw similar issues on other phones and someone said to clear data and cache on the phone app so I don't know if that will work or not.

What time out do you have your screen set to? Sounds like it's simply locking after the designated time.
I've noticed the screen turning on and off occasionally when talking. Almost like the sensor isn't sure if I'm holding it to my head or not but then I do hold it away from my face.

I have the same issue...
I can't hang a call because the screen simply don't turn on when I remove my phone from the ear.
In add at this issue, seems like the proximity sensor turn off the backlight screen only.
When I finish a call, I found the clock screen opened, in my case the settings screen of advanced clock widget...
It's really annoying...

Do you guys have a screen protector applied by any chance? Everyone had this issue with the nexus 4 because the sensor is really sensitive and picks the protector up, not letting it turn the screen on. Try removing a section of the protector where the sensor sits, this will fix your issue.

Surprisingly, I don't have this problem
Team Nexus 5 sucks. Underpowered battery for a 5inch 1080p screen that is non-removable. Weak generic antenna that drops signal. Worst speaker of any device on the market. Cheap plastic build.

I have it on 15 seconds. Shouldn't that feature be bypassed when a call is in progress so that the proximity sensor is usable. This is the first phone that I've had that has done this to me. On all others the proximity sensor stays live even after the predetermined sleep time.

After 15 seconds you're screen is simply turning off as you have set. Mine does so after 1 minute, which is my screen time out setting.

During a call shouldn't the screen timeout be bypassed then go back to the default setting once the call has ended? That makes much more sense to me.

This seems to be the built in functionality of the phone and not a bug. I can't really say if one way is better then the other but I just turn the screen off during calls now.

This is the bug...
really annoying

same problem

I have a similar problem with mine - the screen is gets really dull intermitently. When the screen is dull, I have to set brightness to the max to see anything. So I now have brightness set to max all the time which drains battery - I also notice the phone getting warm towards the bottom as well.

And now my device refuses to start at all . Today I will send it to repair and we how things will go

Back-light initial turns on but then turn completely off

Hey,
My backlight does not want to stay on after I hit power button. It stays on for a random period of time, between 1 to 5 seconds, then completely turns off.
The screen is still on and can only be seen 'easily' in a dark room. Yes, I did turn up the brightness and also turn off auto brightness.
My assumption this is a hardware issue because I open the phone a day or so before the issue occurred for an unrelated issue with the power sticking. Not sure how to fix it in either hardware replacement and/or software.
I install CPU-Z app and it seems that my Proximity & light sensors are working correctly. Attempt to force the backlight always on with "Backlight switch" app but no avail.

Might have to call Google for help. Sounds like a hardware problem

If there is no warranty left on the phone, the cheapest fix may be to order a replacement display assembly from Aliexpress. The third party screens aren't as good as the oem LG screens but they are far cheaper.

If you go the route of replacing the LCD yourself, the website Ifixit should have a guide for you

Display gap

I believe the quality control for these devices to be very low. Anyone who received a deffective device? I realized mine was deffective on the 40th day, T-Mobile replaced it with a refurbished one and it was deffective as well, so I called the executive office and they gave me $300 credit to my account. There was a signifficant gap between the lcd and the metal frame at the lower right corner, I could see metal parts through it if looking from very close.

My screen went out last week had the phone for 3 months.

How exactly the screen went out ?
More info will be appreciated cuz I aint got a single problem.

Started flickering purple and just turned off.. Still had leds and sounds so the phone was on with no display. Sometimes I'd get it to reset and the edge would just have a purple line stay on for bout 5 seconds and turn right back off.. I sent it to Samsung for warranty.

Mine did that too last week. Only had the phone for 2 months. When the battery dropped below 38% the screen would start to flicker. After the flickering it would soon go to black screen. Sound would still work. Just no screen. Got a new phone out of warranty from t-mobile. Received it but now I noticed a dead pixel on display. Have to go back to t-mobile to see if I can get yet another replacement phone.

There is no reason these phones should be defected at all.
