[Q] Mi3 W Accelerometer Bug - Mi 3 Q&A, Help & Troubleshooting

Hi.
I've bought Mi 3W 16GB 2 days ago, flashed russian miui rom (5.4.17), translated by miui.su. Everything was fine, but today the accelerometer sensor gone mad. The phone rotates screen at 180 degrees even if i don't rotate it. And screen rotate freezes in that position, i can't do anything, only return back to the main screen helps. I have to turn off screen rotation to use the phone. I've tried to flash latest sMiui, latest miui.su stable release and even AOSP 5.1.1 by Ivan - it didn't helped. I've tried to calibrate accelerometer in service menu, but every time i try it says only "calibration failed".How can i fix it ?

[Q] Display problem: turns off randomly, or to highest brightness by itself.

Hi again. I'm having a very weird issue, and I thought it was related to my camera problem [now partially solved] because this started happening after the camera incident. The screen will suddenly and randomly turn off, or switch to the highest brightness. To fix it, I have to lock the screen, then unlock it.
I searched and this thread showed up. It's exactly my problem, but I can't do what he did, since I'm not in Brazil. I'm running Kang's CM7.
Is the latest fix important? I haven't installed it because I'd have to wipe everything [again] and I'll need a whole weekend to get my stuff together once more, but if this is key to fix the screen, I'll do it.
I have the same problem, I havent found a solution. Have you found a solution?
Same for me
Same problem for me... the screen suddenly set to highest brightness (only sometimes) and after a few seconds, the screen turn off itself. Sometimes turn on itself in 10-20 seconds but already times, I need lock it (with power butom) and unlock again.
I was testing with a bounch of ROMs (CM7, GB, ICS, etc), but problem always is present. I was cleaned the usb port pins (see that solution from other post) and nothing happen.
...sorry for my english
You can try to reflash the stock rom from www.samfirmware.com based on your region..

Mi5 lcd problem - it goes dark

Dear all,
I've bought recently Mi5 and received it couple days ago, unfortunately I have a serious problem with the lcd. It's really bizarre malfunction, I don't have problem with backlight or touchscreen and I can use the phone normally but the moment it goes to sleep or I press the power button lcd goes dark and it won't turn on. Button back-light shines but the lcd is essentially dead and I can't do anything. The only way to wake it up is reset. If I set the sleep option to "never" I can use the phone normally until the battery drains but it's really awkward and inconvenient. I've been trying to update the rom, wipe all data etc but it didn't help. I even flashed the newest rom V8.5.3.0.NAAMIED via miflash unluckily the problem still remains.
Any ideas?

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!
