proximity switch only working after a reboot - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hey Guys (and Girls?)
Again a problem with my z3 compact. The proximity switch sensor only seems to be working for a short while after a reboot. I do the prox. test in the service menu and it stays on OFF, no matter what I do. I then reboot the z3 compact and do the service test again and bingo it works and the screen goes black during phonecalls (now it stays on all the time).
I did this experiment now 3 times so it's definitely a software issue and I just installed a fresh stock Lollipop 5.1.1 a few days ago! Never had this problem with my z3 compact.
Any ideas??

[Q] Issue with Proximity Sensor on CM10

Hi,
I have a problem with the proximity sensor on my Xperia T. I flashed the new CM10 nightly ROM today. When I want to finish a phone call, it happens very often that the screen remains black. If the other phone hangs up, screen returns after 2-3 seconds. The proximity sensor is working perfectly if I test it at the beginning of a phone call (when it rings on the other phone). It's also working with the stock firmware from Sony, so I don't think that's a hardware failure.

Broken screen - but not cracked - warranty

Hello guys,
i have a problem with my S5 Mini G800F, 2 or 3 weeks ago its started to get something like deep sleep but in fact notification LED was working all the time, after reboot it was working again. Couple days ago screen was black even after reboot (no samsung logo visable, only blue-cyan booting LED), then i realized that when i push screen with finger near the front camera, screen start working, but of course only with that finger pressed
There's my question, warranty services will fix that? Even if is a new rom on it? (Official 5.1.1) I hope not becouse its not soft side problem. I think that connection between motherboard and screen just disconnect and thats why it's stop working.
Thanks for help! :highfive:

Display issue

Hey guys,
My phone barely turned one year a week ago and now I'm having some issues!
The display seems to lose it's sensivity after a 5-30minutes use. Completely random. I can turn on/off the screen, I can use the fingerprint sensor (and it works) but it "feel my touches". It just doesnt respond to my touches.
The only thing I can do is to force reboot, pressing the on/off button for 5-10seconds.
I switched from xiaomi.eu to global stable and it does the same thing. Now I'm going to switch to the latest LineageOS maybe it works.
I couldn't find my problem on Google, all other display issues seems to be different from mine.
Thanks guys! Awaiting tips!

display not show, just backlight and touch

hello, i hope this forum is still exist
i need a sugestion, i've replace my broken digitizer on z3 compact.. first try before re-assembly the phone and trying the screen is all good.. display clear, responsive touch and bright backlight
the problem is i forgot to unplug battery when i remove the flex of lcd
just info, the V fuse for backlight has been jumpered because before my screen has broken it doesnt show anything without torch because the backlight is off.. it was about 3 months ago
when i was finished the re-assembly, it just showing the backlight without any display on it.. i try mirroring with scrcpy to my laptop (my phone was switched on the debug & always trust my laptop) and trying the touch it seems normally but still no image at my phone
i have a same problem with Z5 big before about 1 months ago, but z5 big has V and L/I fuse which for backlight and display.. i've jumper that two fuses.. but i didnt find L/l fuse on z3 compact
what can i do for turning on the display again? i have 2 z3 compact with same problem one for me and one for sell
sorry for bad english, thank you in advance
anyone
