Camera focus working ONLY after a factory reset/firmware repair!

Hi guys,
First of all, sorry for my really bad use of the English language;
Second: I recently switched from a Nexus 6P to an E6553 (because...reasons), and I'm really feeling home with my new smartphone.
The only thing is driving me crazy is...the camera focus.
What's the problem? Simple: it doesn't work, I'm sure it's a software problem and I'll let you know why I think this.
Just after the Setup Wizard, the camera works, and works really really well (it shots awesome pics!). Focuses even little objects such as insects, without the littlest issue. An example is the first attachment: I shot that pic just after a factory reset.
But the problem comes when I restore my apps, my photos and then reboot the phone. Then, the focus literally DIES. No way to get it working, it just stucks. End.
The only way to get it working is...formatting the phone another time and then never reboot it again!
I tried a factory reset from setting, a software repair via Xperia Companion, I even tried to refash the stock ROM through Flashtool (which...simply stucks at "Writing data", and the only thing I can do is repairing the software with XC).
Nothing to do: the camera works flawlessly after a reset/repair/flash, but after a reboot it becomes unusable.
And focus isn't the only problem (as it was a little one ????) : opening the Video Mode in camera makes the device freeze, meanwhile using third party apps for the camera makes me see an huge amount of glitches. The strange thing is that everything works without issues until a reboot, so it's certainly a software bug, but I don't know related to what. And no, it's not an app or something I installed: focus doesn't works even when booting in Safe Mode or creating a new user from settings.
And no again, bootloader is not unlocked, it isn't even unlockable, so no DRM Keys fault.
What you suggest me to do? I really love that phone, but using it with this camera is just impossible.
Uh, last details: I'm on the latest firmware, 32.1.A.1.185, Customised IT (Italy). I tried to flash another firmware (CE1) but as I said before, it stucks on "Writing data".
Thanks in advance.

Today I'm going to send it in warranty for replace the camera. It will be back in a couple days, I'll let you know if the bug is solved.

I have focus problem too.
E6533, .185
unlocked bootloader--->flashed rootable kernel--->TWRP--->root--->flashed drm
After all those steps bootloader is now locked. Everything works fine except rear camera focus.

I managed to fix it! The bug doesn't appears if I skip the setup wizard and I log in my Google account in a second time. All is working well, and I performed a reset 3 days ago.
Yay!

I skipped the setup wizard (initial configuration) at the startup after the factory reset, then I added my Google Account opening Play Store.

Thank you for your solution. But it did not work for me. Maybe because my situation is different from yours. I unlocked the bootloader.

Fingerprint unlock issue... (Solved)

Hi all,
I had the VIE-L09C432B161 Firmware on my phone, everything was fine and the fingerprintreader worked perfect.
Because of a broken display it was repaired and as special "service" they flashed the B180 Version.
So far so good, but now I can`t unlock the screen or wake up the phone with the fingerprintreader.
Is there an issue with Fingerprint unlock/wake issue with B180?
Also when I try to download the B161 oder B173 from the Firmware Threads, I get errors.
It seems the URl has changed or Huawei removed the firmwares from there page.
Thanks!

The B180 works fine with fingerprint. U should send the phone back to service center because i think when they removed the back cover to fix your display didnt atach the flexcabel of the fingerprint sensor to the motherboard.

Thanks.
But I was not clear enough in my first post.
I can register Fingerprint and the Fingerprint reader also deny to register the same Fingerprint again and tell`s me that.
So the Fingerprintreader is working but not the screen unlock feature.

Ok, have u try factory reset the phone?
Sent from my VIE-L29 using XDA Labs

This was a really good hint!
I did`t execute the factory reset, however this remembered me that I removed some games and bloatware from the phone in the beginning.
Accidently I removed also an app called Tastatur-Sperre (Keyboard-Lock). The good thing is: it was in the recycler.
So reinstalled, reboot and TATA. It works again!
Puhhh, really without that I probably missed this change I made.
Lesson learned: Even if you have experience with rooting, removing bloatware and installing custom roms.
Don`t do it if you are sick! And I am sick....

Fingerprint Sensor Replaced, how to re-calibrate?

My p10 was just got back from warranty claim for broken screen. When i turn it on, there was this menu asking to recalibrate fingerprint sensor because the sensor was just replaced (not inputting new fingerprint). It was unclear how i should do it at first, however after few attempts it was supposedly asking me to rotate the phone while the finger resting on top of the sensor.
Too bad, i think my first few failed attempts may have miscalibrated the whole sensor.
Anyone knows how to get back into that menu?

I replaced a broken display on a P10 VTR-L29 and the fingerprint button is not working, everything else is. At first I though the display is faulty, but now I have doubts since the fingerprint option on the menu is just not there. I re-flashed the same version of the firmware (B369) via TWRP and the problem persists. I may have to try a factory reset.

So this is how it ends when noobs messing with phones they don´t understand.
-You can unlock bootloader by paying some bucks to DC phoenix.
When you have no fgingerprint sensor options enabled it points that:
- the fingerprint sensor is broken
- the fingerprint sensor is not conected right

Hi alll
I had the same problem after replacing my screen.
I used Quick tuneup, and since the fingerprint sensor work correctly.

Sorry bro, my fault, i thought you are the one who asked before you.
You didnt say anything about your problem just asked if there is a solution and that you cannot unlock bootloader. With this info no one is able to help you. But anyway:
1. method:
-Remove existing fingerprints
-do a factory reset
-add a new fingerprint (when finger not scaned properly try to push a little bit harder on the sensor and rotate the finger)
-After the new fingeprint is scaned it should work well
2. method:
-after you recieve OTA notification (every month) go to settings/system updates/ there are three dots in upper right corner and select "get the whole latest package". This will download the whole firmware and perform a factory reset low level and this should work (if simple factry reset didnt work for you).
if this methods don´t work i will suggest you to go to phone service.

Oreo Beta - Rollback

Hello,
Try somebody to rollback on 7.1.1? I have request that few days ago but nothing happen.

i read that there is an option from the beta menu...don't know for sure i am still using 7.1.1 but can you/did you check in the system menu or developers etc?

i cant even get into the "boot menu" using volume up +power button. very odd

Starting from yesterday Rollback from Oreo beta to Nougat is working, i got OTA and i'm back to Nougat.

i had to rollback to android 7 via OTA because the camera only worked once and then never again (black screen).
even a factory reset on android 8 didn't help (camera was again able to take only one picture and then black screen again).
of course i immediately reported the problem via feedback function.
wondering why noone in here noticed and reported that so far...
for me, a phone is useless without camera working.
anyways.. now after rollback i am stuck with september 1st security update (rom version 3.08B).
before i entered the ad8 beta, i could receive october security patch on ad7 (rom version 3.09A).
anyone else also stuck and not receiving october-patch when back on android 7?

ok.. that's surprising since even a hard-reset did not solve-it for me.
i used the ported google camera-app with hdr+.
and after taking one initial picture, neither the nokia cam, nor the google cam was working anymore.
nokia cam reports that it can't connect to the camera hardware even after deleting google-camera app.
is noone using the google camera and experiencing the same problem?

After your post google camera uninstalled from my Nokia

because it might not have happened to anyone else. I don't have any issues so far on beta. NIL I have installed the google camera and that app works heaps better than the nokia stock.
edit. No errors of any sort, black screens or hang. Just buttery smooth. Just wondering if the model variant is the cause. I have the 1012

Does the rollback formats/resets the phone?

It does and iirc that warning was given.

I am sick of asking nokia and sarvikas on twitter and elsewhere maybe XDA can help in this matter. As there is no official PC suite of sorts for nokia android What is the best option available to create a local backup including( or mainly ) app data. I need something that can restore it after the roll back as it will be wiped out for some reason. MIUI didn't do that.

MIUI 12 Fingerprint Unlock defective

After upgrading to MIUI 12 Global OTA yesterday, fingerprint unlock stopped working. When I select fingerprint unlock in settings to switch it on and enter my PIN, phone goes dark and restarts (MIUI splash screen). Any suggestions? Phone is stock and not rooted.
Additional info: from CIT menu I ran the fingerprint sensor test. Result shows: all success. Next test (Fod fingerprint input test) gives following message: Your phone has password can not enroll fingerprint information
Not sure I understand the result of this test. Phone of course has a password (required to set fingerprint unlock).

You've got the same problem as me after update to miui12. Have you ever replaced the lcd on your phone? Because I did it.

I installed MIUI 12 through OTA global version. I am not rooted and therefore not easy to reinstall. I might try factory reset, although that also involves some extra work...

I suspect it's because replaced LCD, right now I'm using non original LCD. Is your replacement screen original or not?

See, the cause of fingerprint bug on miui 12 I guess is replaced Lcd. Let's see if anyone fixes this bug

hi guys i have the same issue, please teach me to fix this please i badly need your help

I have the same problem, also changed the screen. I hope some one find a solution for this.. Now i went back to miui11

Eu também estou com esse problema, alguém tem que saber a solução.

I have the same problem. I updated from a fresh MIUI 11.06 (i wanted to remove orangefox cfw to do OTA update) to MIUI 12 via ota update. I didn't register fingerprint in fresh 11.06
OTA went perfectly but when I tried to register fingerprint it crashed and rebooted.
My screen was also replaced a couple of months ago, if the service center uses an original screen? I don't know. I should ask. They provide 2 year warranty on installed screen so maybe they should replace it with REAL one!!

Yah, could be your phone screen not original. Did your phone screen support 5 or 10 multitouch?
and if you already replace your screen on service center and try the fingerprint please update to this thread, I want to know the reason of this bug.

I asked the repair centre if they installed an original oem screen or not. Still waiting for reply.
10 point touch does work though.

Same problem
I'm having the same issue with my Redmi K20 Pro. My display was also replaced to a not original one and fingerprint was working fine at MIUI 11.
After updating via OTA to MIUI 12, it crashed every time I tried to unlock, restarting the device with an infite loop. After that, I made a factory reset, then configuration reset and reinstalled the OTA package but it still won't work.
Hope we can find a solution to this problem!
