Ok so basically I love the g2, but here is my problem, bare with me on this haha, BTW its completely stock n everything as its my 1st Android phone so didn't want to mess with it. So basically I broke my phone screen in January, bought new screen, followed a YouTube tutorial, replaced LCD+touchscreen, no issues super happy, had the odd issue where if I woke screen, would only be on for a second n then go back to sleep, but then upgraded to KitKat through computer software update, still nothing wrong, upgrade fixed the issue with the knock to wake, and then my worst day, smashed the screen again! On good Friday, ok I thought I'll just replace screen again, so I did, but when I put new screen on and tested it, all was well, until I made a phone call, the instant moment I press green call button, screen goes blank and won't come on no matter what, power button don't bring it back on or end the call, but I can hear the other person and they can hear me, had to turn phone completely n back on to be able to use it again, so I though hmmm dodgey screen, but just to be sure it wasn't the phone I put damaged screen back on, and the issue didn't appear, stayed lit up while in my hand, went off next to my ear, back on whole in hand, so I took it to local phone repair shop because I couldn't be bothered going through the hasstle getting refunds etc, they replaced screen, I went and tested it before paying them, guess what, same problem, so what exactly is going on? Has KitKat made the phone not work with a new screen other than the one I upgraded it with? I'm seriously confused and need some bodies help urgently my model is an unlocked lg g2 d802 16gb now I turned it on last week before I took it to be repaired, and it says I have software updates but I didn't bother installing them, is there a chance these could be related to my issue and possibly fix them? Its driving me nuts tbh

Hey Chris. It seems like your proximity sensor is messed up. I think the new screen you got yourself is worse quality or your damaged the proximity sensor when installing the screen.
Edit:
Please go into your phone app (where you call people) and type the following
3845#*802#
Then go into: HW Device Test and then ALC proximity test. Try testing your proximity sensor with your hand. It should change from far to near when your hand is about 2 inches from your phone. The proximity sensor is located next to the camera.

Ok thank you I will try that, I also thought a damaged sensor but when I put damaged screen back on after having the issue with my new screen it worked just fine, no blank screen when making a call, I retested it before I left it at phone repair shop, still was fine, then picked it up with a new screen and issue came back, I don't get why its been like this, I'm thinking bad quality screen and maybe try scratching the sensor area of the new screen to allow more light in? It may be to dark for it, what exactly do I do if it works fine when using that code, try another screen?
Chris
I doubt it will work when you use that method. It's just to make sure that it's the proximity sensor that's the problem and not some loose connection. And yes, a new screen would be your best bet.

Ok I won't try that method then lol, what if it doesn't work when I use that code, as I said I didn't have the issue with the damaged screen which I tested after having the issue with the replacement screen I'd purchased, so how do I know its not just the screen not allowing the sensor to see? Is there anyway I can reset the sensor to relearn maybe?
Chris
If you follow my steps, nothing bad will happen. It's just a way of troubleshooting the proximity sensor. I still think you should do it.
Sent from my LG-D802 using XDA Premium 4 mobile app
Ok I've spoken to phone repair shop and they agree it worth a try to see if its the screen or not, I'll let you know on Saturday after I've been and tested it
Chris
I just had this exact same issue.Turns out the inside of the screen was just dirty. I opened it up and took a q-tip to the inside of the screen and it worked perfectly after that. Also check the readings of the light sensor, as it is right next to the proximity sensor, if the screen is the problem it will likely have low readings as well.
Great I'm glad somebody else has encountered this issue, its been driving me nuts lol ok so I dial in the code that's been mentioned and what are the labels in the menu for the proximity and light sensors? I'm thinking its just a crap screen as the broken 1 worked fine after I put it back on after testing new screen, and I reckon the screen the repair shop has used is also ****e quality, but I just want to cancel it all out as I don't have the phone to hand to inspect as they still have it lol is there a picture somebody can post up to show what to not cover when replacing the screen and applying adhesive tape etc? Just so I can show them to make sure they have done it all properly.
Chris
Ok so just to update the problem, I went to the phone shop today, did the test, it was showing near all the time, but the light sensor reading was quite high, 166 or something, but I then tried squeezing the screen, index finger on back and thumb on front, gently squeezed it, and proximity sensor started showing far, and near as I moved my hand over it, but after few seconds, went back to showing near constantly, so I think its the screen not been seated, told the shop to take screen off, give it a good clean and reseat it. This sound good to you guys?
Chris
Anyone?
Bump! I'm only wanting a little extra advice so I don't end up paying more money out for another screen when it could possibly be proximity sensor? I think it was just the screen not seated properly, anybody have an idea or something else to either assure my choice or point me in another direction?

Good evening... Well recently, i bought a Screen Protector from ShieldZone for my hermes. Well I applied it to the screen and so forth to the rest of my device, then i realized the touch screen doesnt work. I take out the battery for a few minutes, and it starts to work, but after a few seconds, it stops working again. Any suggestions?
This happened when i put my first screen protector on too.. What happened is you put the sticker on to tight; there is an equal pressure over the entire screen , so the processor cannot distinguish your pen touch from the rest of the matrix. All you have to do is take the protector off and reapply it with less force and it should work. (It took a few tries on mine to get it right, did the same thing on my wife's Treo 750.)
well,sounds strange,did you align the screen properly??
Im using a not so costly screen-protector on my hermes without a problem.
Probably u may remove the shieldscreen and make sure dat its not a hardware issue,good luck
yeah i took off the screen protector and still i have the same problem. Anyway i can change the pressure settings?
well,Im not sure about pressure settings but you may try re-aligning the screen (in settings) ,it shud help mostly,hope u have warranty which is not void...
I had the phone unlocked, and I put in the latest Cingular OS, even though i am on the TMOBILE Service.
I have the wierdest thing happen this morning!!! I woke up and turned on my phone, and there is a little smudge in the center of it. Almost like there was a air pocket between the protector and the screen, so i took the protector off, and it was still there!!!!!!!!!!!! So, i pressed down on the little spot and it moves around just like an air bubble would. I turned on my phone to see fi there would be any problems and for some ODD reason, everytime i tap the screen it smushes in that spot. It looks like when you press on the lcd screen of your computer and the pixles kinda move around a little!
Was wondering, I have a Cingular 8525 and would this warrant a repair? Meaning, Could I call them up and tell them what happned and they would send me a replacement?
This is really getting frustrating... I had this phone for only 8 days and its already giving me a headache.
my first for ages.
I recently purchased a wizard which looks to be virtually brand new.
now the other day I updated it the the o2 uk latest rom as it was running a really old rom.
and it has been running perfectly, i have not looked into running any other rom or performance upgrades etc.
now I was using the device in landscape and after closing the unit my screen went bright white and my pride and joy is now not usable.
I can still acept calls, the touch screen still works but the screen is pure white.
Ive contact a few places and they all say the screen has died and needs replacing
Does this sound right.
its a £80 fix if this is right. im so gutted.
any advice is great before i pack it up and send it off.
anyone please....
Can you put it into bootloader mode? If not i would say you have a loose connection on the screen to the mainboard i had the same problem with my old phone the screen disconnected for the main board so no display! If you cant get it replaced take it apart and carefully check the connections if still doesnt work i would try another screen or buy one.
even when i reset it, it stays whits so cant see anyhting on screen,
ive had someone take it apart and re-seat the cables and still just a white screen
so im off to purchase another one in hope this is all thats gone
as your phone is booting up press and hold the camera button, is the screen still white?
cant tell now. ive sent if off for repair.
Im gutted.

I had a similar issue, the keyboard sliding in and out must have worn out the switch that detects when it is open/closed. I had had my wizard a year and the screen started flickering, i dealt with it for a while, then the scree was stuck blank white unless if i pressed on the area of the phone that had the contact.
I had to send it back and got a refurb.
sounds like thats what happened to you too. Hopefully when you get it back it will be good as new
ive sent mine for a screen replacement tho not a repair.
now im worrying that its gonna come back in the same state.
Gulp
got my wizard back after having the screen replaced.
2 days later when ever i touch the bottom of the screen with pen, finger or even breath on it.
the screen goes off and the phone locks up and dies.
I have to take battery out and restart it and it then works great till i touch the bottom again.
Sound like a dodgy screen or something else.
Seems like a flexi strip(The one conecying the display to the mother board) sometimes if the strip develops a tear or is not properly connected this issue usually happens.
the shop doing the repair have said there is the following issues
1- padding issue on the screen (either too much or not enough)
2- Problems with the main board. (something on there is failling, hardware wise)
How the hell could this be happening on a device that was working perfectly
apart from the screen had died.
have they done more damage attempting the repair... I think so .!
I had the white screen 6 months ago. Luckily still under warranty period so got it repaired. It was the flexo-cable. since the fix no problem so far despites using the phone (also in landscape mode) daily.
when i got it back after the screen was replaced my xda worked great but as stated as soon as some preasure was applied to the bottom of the screen it would just die there and then.
I would have to take the battery out and then it would power on as normal
but again if i put presure on the bottom of the screen.. bang DEAD !
so sent it back to them and they told me what I stated above !
now waiting 2wks to hear what they are gonna do about it
not a happy bunny
still nothing back from the company thats doing the repair.
i dont know why they do this.
Im now thinking of getting my Xda back, selling it either on here or ebay and purchasing a new one.
Should i quit now or wait out for the miracle that they fix it completly.
Anyone in the uk reconmend a good repair company please im pulling my hair out.

I have a serious problem. I noticed a bug in the Desire alphas where sometimes when the backlight went off during a call it would not come back on when the i took the phone away from my face. It always came back on eventually.
Ok now yesterday I flash alpha 8 and it worked fine. Now all of a sudden I reboot my phone bc the battery dies and the backlight won't come on at all! I know the phone is on because the haptic feedback and cap buttons are on and if I leave it on I can tell it's getting notifications.
How am I supposed to fix this?! I can't even see anything to get into recovery! My phone is unusable.
Find out every step to do a backup in recovery... see if that works

Load into bootloader
Press power button once and wait about 20 seconds
press volume down once then hit power button once
Wait about a minute and move the trackball down slowly 3 time and press it
Scroll it down once and press it four times

Unless your screen is broken you can always boot into recovery.
Take out the battery, then put it back in.
Hold the trackball down as you power on, this will boot you into fast boot.
Select bootloader, then select recovery. and bam your in recovery and can reflash.
I can get my phone into recovery. When I adb in i can push the phone into recovery, then when i hit adb devices it shows my phone and says recovery.
the problem is the backlight is not on even when i am in recovery. i would say the screen broke, but it seemed like a software problem, because it was just slow to come back on. It still always came back on. then I left it in my car chargine and it never came on again. The phone seems to be working fine though.
Kind of off topic, but did your call screen do this before flashing to Desire at all? Did you recently install a screen protector? I had problems with the PhantomSkinz screen protector making the proximity sensor less sensitive and behaved exactly how you're describing...as soon as I took it off it started working again. I'm now using a dcmugen88 screen protector and it works great.
interesting. i have one of those bodyglove or whatever protectors. best buy glued it onto my lcd. i suppose it could have started around that time. but would the proximity sensor still be deactivating the lcd even when its booting up or in recovery?
Oh, I must have overlooked that. The screen protector wouldn't cause any issues on startup or in recovery... guess it must be the rom then.
well, figured it out.
warning to n1 users: watch that lcd screen under the glass. its not nearly as sturdy as the glass cover.
the lcd/digitizer screen under my glass got cracked and stopped working. no drop, no warning, no funny colors. htc does not cover this in the warranty no matter how good the actual phones condition is.
i almost didnt get another n1, a phone thats inherantly weak (i found dozens of similar reports over the web) is not exactly a good case for a system with no insurance, no store to walk into, and very unhelpful support. they try to be very nice, but the rep i talked to couldnt even tell me whats covered and not. he just said let us charge 500 bucks to your card and we will ship a replacement, then decide if we think you have to buy it once we get your old phone. i demanded to talk to someone who did know. his manager denied hearing about lcd screen problems... after the original rep said he and htc knew this was a common problem. google didnt even return my email when i first contacted them saying my backlight was broken.
so again, be careful and get a good case.

Hey everyone,
I got my Galaxy S4 (i337m) about a month ago, and loved it from the get go. Long story short, I recently dropped my Galaxy S4 on the floor, from desk high. (I know, it's my own damn fault) It was in a small protective case (cheap case from rocketfish) that only covered the back and a bit of the front). The case took most of the shock, almost shattering (my fault for buying cheap cases) and I made sure right away if everything was ok with my Galaxy S4. No scratches, screen is great, and a few calls and text messages confirmed that everything seemed fine.. except for one thing, the air gestures are not working anymore.
I tried everything, from a hard reset to disabling/enabling the options in the air gesture menu. When I test out the quick glance in the demo menu, it just automatically turns on without me waving my hand; while the other air gestures, nothing happens. I would think there would also be a problem with the proximity sensor because now my phone just goes black right after I call someone and stays black when I move away from it. Direct call from a contact page is also not working. The light sensor is still working however, because depending on the lighting my screen changes automatically.
I would like to add that I am out of my return period. I would like to add that this is a minor problem... I barely use the air gesture function and the proximity sensor during calls is not that much of an annoyance. But, being the techno geek that I am, it would be nice to figure out how to fix it.
Thanks in advance!
If anyone can help, I will be much obliged. If not, I'll just go on the same way I've been going
Although I would never advocate it myself as long as there is no physical damage to the phone that could not be attributed to normal use (this means that nothing on the outside of the phone can be cracked or even seriously scratched and both LDI's on the battery and phone must be white) you may be able to simply call warranty and have it replaced with a 'refurbished' device (i337).
Sent from my SAMSUNG-SGH-I337 using xda premium
I don't even think warranty departments have even had enough time to refurbish returns or defective devices to Samsung standards.
You should get a brand spanken new GS4 from them.

Hope that help
Hi all,
I recently replaced my screen with one off ebay. So far, so good. Screen looks great and I'm happy to have my phone back after a month with a cheap zte blade. However I make my first call, screen stays on as usual, put the phone up to my ear, screen turns off, I go to put it on speaker and the screen stays off. Ok, I guess there's some dust in the proximity sensor. I make another call, and the screen stays on until I put it up to my ear, so it seems it's working again. Once more, I go to end the call but the screen stays off again. Weird, I thought it was working. So I download sensors test app. When I open the app, it shows the sensor reading far. When I put my hand up to the sensor, it reads near. When I take my hand away, it remains reading near. If I turn my phone in the side it goes back to reading far. Put my hand up to it and it reads near again, and sticks when I take my hand away. If I switch apps and come back it reads far again.
I was on 7.1.1 beta, so I downloaded Feb 7.1.1 and the problem is still there. I have limited monthly data so was hoping somebody may have some ideas before I download another factory image. I have already tried proximity sensor fix app.
Thanks

My phone does that. I thought it was normal behavior. You can download an app that keeps the screen on for whatever apps you choose. The one I use is called Screen Manager Pro but there are others that do the same thing.
No screen protector right? Have a look at thread and see if it may pertain to you. Particularly the part about the missing grommet over the proximity sensor.

OK, I am missing the grommet and unfortunately threw away the old screen already

I'm not sure how you can make one. It seems the guy in that thread didn't have much luck. See if an official repair center is near you and if they are maybe they would sell you a grommet? Or repair it for you worst case. I bet they are aware of how critical that piece is.

Well, the bad news is, I live in a very small rural area so no repair centre nearby. However, the good news is, since I live in a very small rural area, I went to the rubbish dump and asked about the collection from my street. The bags from my house were right near the entrance with no other trash on top of them! I retrieved the old screen, went home and cleaned up and installed the grommet and I am back in business!
I never thought I would be so happy to trawl through a garbage dump but here we are. Thanks for pointing out what the problem was!

You retrieved the grommet from your city dump. That is pretty legendary!
