Faulty magnet sensor - G 2014 Q&A, Help & Troubleshooting

Hi,
I have a second-hand Moto G XT1068 which is unusable because the magnet sensor thinks a flip case is closed on it and keeps the screen off. I can access the bootloader (unlocked) and recovery (TWRP) but Android (Stock, factory reset) is unusable.
I can't get the hardware repaired right now, do you have any ideas for a workaround that would disable the sensor? I thought of modifying a stock ROM to disable the sensor and flashing it, but there may be an easier / less drastic way.
Hope this isn't a stupid question, I am new to Android phones!

Update: I have managed to enable USB debugging (not easy without the screen) so now I have shell access. What process watches the magnet sensor to lock the screen? I could temporarily get access by killing that process, while I install a permanent fix like MotoMagnetOff.

Touchscreen Problems

I just upgraded my Rom for the x time, this time my touch screen will no longer work in landscape. I downgraded to a ROM that used to work, and on that ROM my touchscreen also does not work in landscape mode. Is this a software thing or a result of throwing the phone against the wall to many times? i guess it's time for an 8525....
Any ideas how to get the touchscreen working again?
e.
same problem for me !
It's not switching to lanscape? While opening keys? Or just turning off?
If it's able to be switched with software way (Settings -> Screen -> Landscape), then this is a hardware problem.
Wizars has a magnetic sensor to detect keys sliding, try to check it (use an external magnet).
If screen turning off after sliding the keys, the flat cable is damaged.

[Q] only digitizer works after 2 foot drop onto carpet.

Hello XDA,
So a Moto X 2014 was dropped from the height of a couch to a carpeted floor earlier today (my friends moto ). He picked it up, inspected it and then resumed using it after seeing no evidence of damage(no cracked screen). Next he turned the screen off. After a bit, when he went to turn the screen back on, it would not. The haptic feedback still works when hitting the home key and other parts. I can even drag up to get to google now, then start typing into the search bar. All of this is done by feel, without the screen being on at all. Also of course "ok google" works too. The phone also gives sound feedback. So now you guys get the picture here, only the screen does not work, and the digitizer does. I have two questions here:
1. How?
Why on earth would the phone still work until the screen was turned off?
2. Is there any way to fix this?
My hypothesis was that the display connector somehow became ajar due to the drop, which would require a teardown, which we will not do. Would a battery disconnect help at all. I think we may be willing to risk peeling off the back to disconnect the battery.
The phone is most likely going to to be returned, however if there is something we can do which might work possibly via software on the computer that would be great.
Thank you XDA so much for your help!

Enter boot loader. Turn off your phone and then press enter and volume down. After that with the volume down go to "factory" and press volume up to select it. Your phone will restart with out radio signal and a Commserver app on your status bar, there you can select the first option and check all the system hardware. Hope it helps.
Regards
I can't access the bootloader because the screen will not turn on. I would not know what I was selecting. That is the source of the problem. Thanks though.
Is there a way to do a factory reset over usb with adb? Also I cannot find the required drivers.... anyone out there?

Yeap. But first download minimal adb and Fastboot drivers then search for the firmware of your phone
The command is
Fastboot flash system system. img
I think you need to unlock your bootloader in order to flash even stock system files
Since you dropped it it is rarely possible that software is "broken" better to do is sending to motorola asking for warranty (if no signs of drop are visible) an hope.

Stuck on "Cover View" after screen replacement

Hi folks,
I recently ordered what appeared to be original huawei p9 replacement screen together with metal frame and replaced broken screen. Phone now boots normally, I can also boot to fastboot and recovery, but unfortunately phone doesn't have ADB debugging and OEM unlock turned on.
When phone boots normally, I can get only to the lock screen of "Smart view" or "cover view", so I cant unlock phone or anything else. I tried also with mouse via OTG, no luck...
Anyone have some other idea that I can try? If i could enter settings to turn off cover screen all would be good
Cover is usually detected by magnet.
Could you try to play with some magnet or cover from another phone to get it unlocked for once.
Maybe, making an incoming call could help to unlock.
Once you get in (?), go to Settings, Smart Assistance and permanently switch off Smart Cover - it's by default on, most people don't have the cover and IMO it helps draining the battery

I tried the magnet, no luck. Also incoming call is impossible since I get no SIM pin input prompt at startup... Any other ideas?

You can move SIM to another phone and disable PIN, then put it back to Huawei.
Not sure would it help, you may have hardware problem with the replacement parts or work
To clarify this issue - the problem was in charging board, so changing it solved the problem. Other solution (if everything else works) is to remove charging board, boot the phone and disable smart cover in settings & then inserting charging board back.

Black screen and only Clock, date and weather

Hello,
My Huawei P20 Pro got stucked in a mode where displays black screen and only for about 40% of the screen, in the right it displays clock, date and weather. I can be called, the phone is charging but that's all. I had about ~70% battery when this happened. Reboot doesn't resolve the issue.
Any idea?
Thank you!

This sounds as if your P20 Pro is stuck in the mode for a closed flip case with a window (see https://i.ytimg.com/vi/G7sU3yGpRF8/maxresdefault.jpg).
That mode is normally triggered by a magnet located in the lid of the flip cover. Do you maybe happen to have a magnet too close to your P20 Pro?
Thanks
That was the issue. I just took off the case (which is not with flip) but it has a magnet for car. Thank you for your reply.

Go to settings -> Smart assistance and turn off Smart cover
hi, I have this issue. no flip case... n I can't into settings to turn off Smart Cover any ideas?
Anyone managed to fix this? I have the same issue. Tried everything, safe mode, recovery, restarting... I do not want to lose my data, is there a way that I can login and back up my data and then factory reset it? I cannot login because the screen is irresponsive and cant insert the pin for the screenlock, otherwise the screen itself works.
Dissconnect the Charging board

remove gently the back glass without damaging the finger print sensor flex and disconnect the main flex cable which goes from the second board to the main board, and start the phone without connecting the man flex, you will be able to go to settings and turn the slim cover option off
i have done almost everything talked about above on this phone for a week now but the black screen with date and battery percentage cant go off and the phone cant open anything else. its where it stops. what do i do . guys i need help i feel frustrated
Did anyone resolve this issue?I have same problem.however my screen did come back for 10-15 sec back and i manage to do hard reset but now i am stuck on black screen
Maybe too late, I was changing my battery already, then same thing happened to my p20 pro. I tried to use magnets to try unlock to no avail. Anyway read that the hall sensor is just at the upper left of the fingerptint sensor. After replacing the battery, turned it on, smart lock still active. Flipped it backwards, unscrewed the bottom right screws and gave it a few tap or knocks by hand an voila, screen is back to normal. I cant pinpoint the problem was, but thats how i fixed mine

Xperia z3c proximity sensor issue

I got a Sony Xperia z3c d5833. Yesterday I installed an app named pocket lock. The main feature of this app is to lock the screen when you cover the proximity and light sensor. Now the problem is just when I Uninstalled this app, the proximity sensor permanently switched ON automatically. And I can't view my screen during calls. I replaced the proximity sensor kit and also re-installed the firmware and went into stock mm6.0.1 from kit kat 4.4.4. Also installed the lollipop 5.1.1
But invain and the problem is still there. My proximity sensor kit which I replaced with another Xperia z3c is working fine in that phone.
I need help....
There is a problem with the display glass on the Z3C separating from the sensor, with an always ON sensor the result. Google and you'll find it.
You can test it in the service menu. It will show as ON, and go OFF if you lightly press on the top left corner of the display.
So you might have a hardware problem. Sometimes just glue the display corner down works.
There are also a few fixes that disable the sensor. You really do not need it. It is a battery saving feature.

All was going fine and fantastic until I installed this fckn app pocket lock ? there's no need to change the proximity sensor kit now because I already have changed it and the most interesting thing is that the faulty proximity sensor kit doing fine in another Xperia z3c. To assure myself that new kit should work fine in my phone I flashed it thrice with three different ROMS but nothing worked. Now I'm wondering how a software can damaged a phones motherboard. It means there's only two things left for me to change, Bootloader and motherboard. D5833's bootloader isn't allowed to be unlocked so therfore I can't upgrade the bootloader, now the only thing left is motherboard of my phone. .
