[Q] Proximity sensor not working properly - Xperia Arc Q&A, Help & Troubleshooting

HI,
I guess others have had this problem but i cant really find the answer.
I have a problem with proximity sensor that i have to press the phone at the top left side in order to switch it off after its on. It works fine like that when i test it at service tests but when i don't press the phone at the top left side it does not turn off most of the time. Yesterday i also had problems that the screen was off for few minutes at high light no matter what i did. since i finished what i had with phone i did not remove the battery to see if the problem will repeat, all i did after the screen was on, was a reboot but i did not have the chance to test it again at direct sunlight again.
I don't have something on top of it, all i have is the screen protector that came with the phone.
it is with unlocked bootloader, stock rooted rom, supercharged and with removed bloatware software's. this is all i can remember to tell for my phone, i have never tried other custom rooms since i did not have the time because of school.
The phone is new, not even 2 months old, hope i don't have to send it to repair.

Tilt 2 partially dead after succesful stock ROM update

Ok, I was having some software issues with my Tilt 2 (TP2) and I talked to Tech @ AT&T, cause I wanted to get it exchanged. So they had me go and check to see if my ROM was outdated, which it was. I bileive it was on 1.59-ish, and now its on the most current one direct from HTC's Support site. My main problem right now is that the phone is 99% unuseable at the moment. AT&T has already agreed to send a replacement after talking with them a few hours ago, but its going to take about a week to get here, and it'll most likely have the same ROM and the same problems, so here I am posting to let people know whats going on, and see if anyone else knows what causes this/has this issue.
Right now the phone is completely stock, only installed app is MS My Phone so I could sync my contacts. I can let the phone sit till the screen shuts off from idle, but if I need to turn on the screen once it turns off, it requires the battery to be taken out. Right now my phone is sitting in front of my keyboard, with its screen black and off, while the keyboard is lit up. Something to note - the keys on the bottom of the screen are NOT lit up. Pushing buttons on the keyboard does nothing. Caps Lock and FN do NOT light up their coresponding indicator lights. If I am lucky, I can get the phone to come out of this state by having someone call me, but aside from that, taking out the battery has been the only way to reset it. Only way to keep the screen from freezing is to constantly use the phone. Using the phone is slow as balls. I thought TF3D was slow, Sense is just as bad. It worked perfectly fine at first, right after it was updated, it was nice and fast, but now that its been used for a few hours, its sluggish.
Anyone ever had this issue with this ROM?
And does anyone know how to possibly fix this issue, or at least get it so the screen will show that its on? I can deal with it being slow, so long as I can use the screen
Thanks guys

You already ruled out a software issue by flashing another stock ROM. This is something hardware related. Sense on the AT&T ROM is dreadfully slow. Use a custom ROM if you want the features of Sense, but in a faster iteration.

[Q] Galaxy Note 2 Black screen after cyanogenmod

Hi,
I installed the cyanogenmod 11 nightly like a week ago on my galaxy note 2 and all was running perfectly until this morning.
When I woke up this morning the phone screen was black. The phone is actually working, I can hear emails notifications, phone ringing etc.
The buttons light up when i press them. When I connect it to the PC I can browse the phone contents etc. All seems to function except the screen.
The battery is charged. I tried to remove the battery for a long time and try again but still nothing.
I can't get into recovery or download mode as the screen is blank (sometimes there is a like a weird area at the top where there are like different colored pixels present). I know people will say the screen might be damaged but last night before I went to bed it was all fine, the phone was placed on the table, and this morning when I picked it up screen is blank.
I want to flash back the stock firmware. However I can't get into download mode in order to use Odin. Is there any other way to get into download mode or hardware reset the phone?
Any suggestions are welcomed.
EDIT: The touch screen also seems to work when I touch it as I can for example call numbers for which I had speeddial scortcuts but it is still completely blank.
I think this is hardware issue. You must replace the screen

Yeah I think so too. I've sent it to Samsung.
It was rooted and had cyanogenmode so probably I have no warranty
However I managed to install stock ROM so hopefully they won't (can't) notice.

HTC desire 816 anoying turning off PLEASE HELP!!

Hi i have this supper anoying problem after 5.0.2 update! So basicaly What it does is when ever i will pick up the phone it would turn off like the screen would dim (not rebbot or shut down) and after a little tapping on a screen it would turn on again and sometimes when it does that it would glitch a little. While typing this it happened twice its sooooo anoying idk what to do now if i wont find any solutions i will just buy samsung galaxy or something like that. Also my carrier is Virgin Mobile thanks
Same problem, same phone.
Definitely annoying! Seems random but especially while rotating for me. I have not been able to dig up any solutions thus far.
Check out your proximity sensor settings in the HTC testing app, or try Gravity screen. Mine did the same thing a couple times, also clean off your screen at the very top left, if you look real good you can see the sensor just under the front camera hole in the glass, also sometimes a screen saver will mess with this sensor. One more thing is the stock lock screen can cause an issue similar to what you are talking about, hope one of these help yo out, cane0716
Sent from my 710C using XDA Free mobile app
hi
thanks for information i already gave that phone to my friend and i think he fixed it by actually having different lock screen i currently have samsung galaxy s5 its wayyyy better lol
Phone turns off during use and will not complete boot unless plugged to charger even when the battery is almost full.
This error started last night after I did factory reset because of observed phone lag. I did mistakenly "wiped internal storage" but got the alert of "no OS during reboot", so I restored from my backup from SD.
the phone started properly but went off during initial setup and will go back off each time I tried turning it back on. I thought it was battery so I plugged it to power.
it did boot but will go back off once I have few touches on the screen.
I had to leave it plugged to setup my accounts else it will go off.
I'm using its Wi-Fi to send this message via my PC because any 2 - 3 touches will switch the phone off.
once it does that, it won’t even boot to bootloader before it goes off again unless plugged to power.
what I do to solve this please??

[noob inside] - Screen unlocking problem, faulty device or android bug ?

Hey there guys , I've been searching through the forum topics about my issue but so far I've found nothing close to my scenario.
A few months ago I bought my first HTC phone (M8). Its a great device for sure , despite the fact that I had to return it back twice.
First time it was a faulty microphone , so they sent me back a brand new device. Great isn't it ?
However recently I've noticed a few .... let me call them 'glitches' .
Let me give you some details on what I've experienced with the device:
Despite the issues that i'm going through ... the phone works great, but...
Sometimes the screen wont turn on when I'm receiving incoming calls (same goes for the alarm clock) but the phone is able to recognize touches - i've managed to pick up the call when I swiped the screen in the area where the "green" answer button appears .
The above issue doesnt happen so often but the thing that bothers me is the unlocking issue.
At first I thought that it was stuck or faulty power button.
When the phone is idle for some time and I pick it up and press the unlock button ... nothing seems to happen I've tried pressing it hard ... i've tried pressing it gently ... i've tried pressing it multiple times until the screen wakes up .
Same goes for motion launch unlocking .
When I use motion launch to unlock it the phone only gives me a vibration feedback ... and thats it until I try harder to bring the screen back to ''life'' .
(I can also press my security pattern buttons while the screen is dead and feel the phone vibrating , BUT NOT ALWAYS , sometimes is just .. dead )
I already sent the phone back describing the same problems and they just flashed the firmware , which did not fix any of the issues.
Stock Rom android 5.0.1 , not rooted
Soo what do you guys think? What can I do next .. is it android bug or a faulty unit ?
is it possible to be a sensor problem (proximity , accelerometer)
Already tried factory reset and dalvik cache wipe.
Any advice would be useful.
Thanks for taking your time .
Cheerz
I have the same issue. There are times it takes me hitting the power button 20 times for it to finally light up but I can press buttons with it black. The weird thing is it does it on every single ROM but I havent noticed it on Stock...maybe I'm not using stock enough to see. I'll probably throw stock on there today and take it into sprint and let them replace it.
I have the same problem whether it's on stock or custom ROM (KK or L). I am pretty sure this is a hardware problem. Unfortunately, my m8 is out of warranty so HTC won't fix it for free. I read it some where that it could be a faulty proximity switch so shining a light beam to the top part of the phone may wake up the screen. I haven't tried it yet because every time it happens, I don't have a flash light handy. It is an annoying problem to say the least.
When this happens, I pushed the power button, the volume up button, and swiping the screens. Eventually the screen would wake up and every thing works fine... until the next time.
Its a ****ing pain in the ass.
however none of the sensor reading apps report a faulty/stuck sensor.
the wors thing... I've already sent my phone for repair, describing the problems in details. .. and it took them a whole f*cking month to bring it back to me with no results.
I don't think they will replace it because its a problem that takes time to be experienced...and no one is going to wait for it to happen. ...
Any other ideas?
Should I wait for android 6.0 or should I try a custom rom too see if these problems presist.
Fml I love the phone but this is frustrating.
I have the same problem I think. I just bought an M8 on Ebay. I am S-off, unlocked and rooted, using the Viper Rom currently. I have also tried AICP, the stock Tmobile Rom and a few others. Same issue.
If I double tap, I feel the screen vibrate, but nothing comes on. Then, I keep pushing power button a few times. Sometimes it comes on and sometimes I am too impatient to wait, so I just hold power and volume up.
I also know that the phone internals come on, because after that vibration, I swipe up and push the screen a few times. Then, when I am fiddling with the power button and it does come on, I do see that there is an app already on the screen.
I think this is a rare issue, as I haven't even been able to find many posts regarding this. I may have to get a new one if this keeps going on so bad.

I am experiencing the exact same issue with my M8. I have seen a lot of people stating it may be a hardware fault related to heat and internals but something about how it reacts seems software related.
I really hope someone who has fixed or uncovered the reason comes forward. At this rate I may be switching back to a S4 LTE-A.

I think it IS hardware related. I was able to return that one and got another M8. No problems at all.

Phone working but screen black

Hello everyone,
I have since the first time an LG G3 (D855) that I root and that works very well.
Recently I bought a new one from a friend for my girlfriend.
He never root it, he reset it and sent it to me by mail.
At the reception, I turn on the phone and there, I have the LED lights, sound start but nothing on the screen.
It reacts when I put the finger on the screen so the touch sensor works.
I try a restart and battery removal but nothing better.
The screen has no shock but I told myself that perhaps during the trip he took a bad cut.
I hope it's just a miswired table, so I dismounted to check, but still nothing.
ThenI try something, I disconnect my phone too and I swapped motherboards.
And then the screen with my card in it work.
While my screen with the motherboards of the phone I just bought stay blank.
So the screen is not broken, perhaps it was a install problem.
So I use LG Flash Tool to reinstall the original rom (following a tutorial )
Everything goes well and ends without worries.
But that didnt change anything, the screen is still black.
Do you have an idea ?
Thank you in advance for your assistance and sorry for my bad english
I just realized that if I strongly illuminates the screen I can see that it works.
It' like brightness was at zero.
It's not a screen problem because when I plug it to the other motherboard brightness is ok.
Someone had this issue?
Same problem here
So I'm having the same problem at the moment, but this is the 2nd time that this has happened to me. Last time. I fixed it by changing charger. It worked for like 2-3 month and then I switched again and the problem came back. I suggest you try a few charges. It took around a week before it got fixed.
Hope it'll work for you.
BTW it was a Nokia charger

Exactly the same problem on my LG G2.
It often go to black screen, but it's not totally OFF. Touch work, and the screen the same, i noticed using a torch that the brightness when to something like zero, but if i increase the level, it stay dark. Only press power button sometimes come back, but few second later... Dark screen again.
It happens everywhere during boot, in home, in lockscreen, in TWRP.
I tried:
- Change rom
- Flash stock firmware...
- Totally switched off for 2 months
- Detach and reattach the screen
- Test proximity sensor in hidden menu
Nothing worked.
If anyone has an idea...
