Hi, I've searched this forum and the Internet in general about proximity sensor problems but it seems like basically every problem that someone else had was fixed by removing tempered glass/screen protectors/cases/covers. I'm having a proximity sensor issue and I'm not using any screen protector or case.
This has happened twice now. Once when I was listening to visual voicemail, once when I was making a call. The screen goes dark and will not respond to any wake commands. Every now and then it will turn on for half a second when I hit the power button but then turns back off again. The first time when I was listening to visual voicemail, I had to hard restart the phone by holding volume up and power. The second time during the call, I managed to hang up the call in the half second the screen came back on, which ended the problem.
Right after that, I tested the proximity sensor using the SMMI test (calculator .12345+=). The test makes you put your hand near the sensor, then away, then near again. During the test, the phone immediately sensed my hand near the sensor except that my hand was nowhere near the sensor and there was nothing else near the sensor either.
I did a reboot and ran the test again. This time, the test finished correctly. The phone did not detect my hand until I actually put it near the sensor.
I'm running stock everything except I do have root(ZE551ML). I'm leaning towards this being a hardware problem and I've only had the phone for a week so I'm well within my replace period with Amazon. Is there a solution to this I'm missing or should I just replace? I'm a firm believer in troubleshooting first. Plus, setting up the phone the way I like again will be a huge PITA.
Thanks.
I would replace. It does sound like a hardware issue, and your better off getting a replacement instead of a possible pain for the life of your phone.
I get the same, and the flickering screen happened once to me after I I have just put a tempered glas protector on it ... removed it and so far no problems, but who knows.
I think the SMMI test works correctly the first time you start it, and incorrectly the 2nd, 3rd etc ... dont think it is a hardware error ...
Hi all, i have a zen2 with this same problem, i think doing sensor calibration can resolve the issue... but i can´t found how to do, by code, or by app...
Any body know how to do calibration of sensor aproximty?
Thanks in advanced!
Ps. I dont have screen os glass protector...
i don't having tempered glass or any screen protector. my proximity sensor is not working. Even i checked .12345+= but it gives error in proximity sensor. what to do? plz anyone?
same problem
Hi to everyone,
I have the same problem with the proximity sensor.
After a device reboot, the simmi test work correctly, but after some hours the test fails.
Someone know as I can calibrate the sensor ??
Thanks
I just fixed mine, cause I was having that issue for a LONG time now.
I actually just stuck a piece of paper in front of the light sensor part of the sensor window on the screen. It's the right side of the sensor window.
To be more clear, a while back my screen broke, so I ordered a screen online and changed it. Ever since then my prox. sensor didn't work, so I couldn't use the keypad during calls (the screen would go black).
My screen still isn't attached properly, so it's just being held in by the floppy protective case I have on it right now. This allowed me to pull the screen away from the phone a bit and slide a piece of paper behind it right in front of the light sensor. As soon as I blocked the light sensor then the proximity sensor started reading properly.
I got the idea because I was trying to clean the screen, thinking that it might just be dust blocking it or something. That didn't help, so I tried cleaning the sensor, but had the calibration test running at the time, and it instantly worked!
So I kept playing around with it and noticed that every time I blocked the right side of the sensor, it worked, but as soon as I removed the brush I was using to clean, it stopped working.
I stuck a piece of paper in, and BOOM, worked just fine.
People might want to build on this and maybe try sticking a piece of tape over the right part of the sensor. I haven't tried it, and since I finally have it working now, I really don't want to play with it too much and mess it up.
Hope this helps anyone else having this issue.
Hi all,
I am using zenfone 2 laser z550kl. Screen blackout during call and did not come up till the call is cut. I changed only the cover of proximity sensor and phone is working fine. Change the small rubber covering of sensor and it will work.
Hope this will help all if still using asus phone.
I just replaced the screen on my HTC One M8. The top 1/4 of the screen became unresponsive. I followed a youtube video, disassembled, replaced the screen and then reassembled. Everything went great. new screen works perfectly. Later o noticed that one of the corners was "popped up" I can press it down and it seats for a moment and then pops up again. The screen is lifted just a tiny amount, but it's enough to bleed light out through the sides. Any fix for this? Can i use a small amount of super glue to secure it? The bottom of the screen has a black HTC bar. I feel like gluing it should be OK as you wont see it under the black bar. Any advice or links to other fixes are appreciated.
My HTC One (M8) started to have flickering screen issues a few days back, sometimes the screen wouldn't turn on, occasionally it would turn on, but it was barely noticeable, because the backlight didn't turn on. I realized that slightly bending (no extreme force, of course) would influence the behavior: Top left, bottom right as pressure points makes the screen work, top right, bottom left makes it stop working. Similarly applying pressure on the sides (the middle of the lower half, roughly) makes the screen not work. It looks like it might just be a loose connection somewhere? Anybody have a tip for what to do about it?
And now the screen doesn't turn on at all anymore. I guess that was expected. I googled around a bit and it seems like the company doing repairs for HTC in Austria is shady and known for blaming things on mechanical or water damage (the phone fell down, but that was about six month ago, and except for a few scratches on the metal nothing happened).
Does anyone have an idea if this might just be a loose contact somewhere that I could fix by myself?
Hi all-
My MZF went for a swim a couple weeks back. Put it in a bag with some DO NOT EAT desiccant packets for a few days, actually got it to turn back on, except the Power Button didn't work and the camera crashed every time I tried to open it.
I replaced the camera module and volume rocker/power strip with OEM used parts from eBay. Phone came back on, power button and camera worked, and everything actually seemed good until I plugged the phone in to charge.
I came back a little while later and the screen is black. Phone still vibrated on fingerprint touch, and when trying to power up/down with the power button. Did not come back on reboot, and every so often can see a very brief flash on the screen. No sound either. Thinking I somehow fried the display when I plugged it back in. Thinking about getting a replacement, but all the used ones on eBay are scratchy and/or burned in, and all the "new" "OEM" ones just seem shady.
Anybody ever done anything like this? Looking for any insight!
get a scratched screen and lay a glass screen protector on it this will hide some imperfections and prevent more. i replaced my screen once already and it waqs a pain but my moto branded part works great it came from a bad imei number
Found a decent OEM screen on eBay, didn't appear to be in too bad of shape. Definitely going to put a screen protector on it to help with any scratches. Sitting in my PO box right now, and and gonna try installing it this evening!
I am debating replacing mine. The screen scratched at the FFC and made any front pictures blurry. Did some rigging as a temp fix, but the camera sensor is now not covered by the plastic. If I do replace of, I'll do a tear down video. The screen isn't too hard to remove. Of almost came of when I ripped the protector off.
Hi,
Unfortunately for me i dropped my phone and cracked my tempered glass in several places. gladly the screen underneath was perfectly fine after drop however, it has developed a fault as the screen won't turn on at all. I tried turning it off and restarting and although i can hear the boot up logo sound i see no picture at all. i can receive calls but cannot answer due to screen not displaying.
The screen had four main pressure cracks.... one is top left, one on the ear speaker, one bottom middle and one bottom left of phone. hopefully you can see it in picture.
Can you give advice on what to try or do to resolve this? will i need a new screen or disassemble to see what the issue is?
I've only had the phone for 2/3 months at most
Thanks in advance
looks like i will answer my own question....
i bought a replacement lcd & digitiser, one complete unit and swapped the necessary components over to new screen. all is working and good. not sure if the screen is repairable but there are other parts inside this screen worth selling on. it still has a non cracked immaculate screen along with the charging port and other stuff inside old screen.
at a cost of £70, i consider this an expensive fix
Thanks for the input kakawak
cheers
