New Display - Fingerprint calibration issue - Xiaomi Mi 10 Ultra Questions & Answers

Hi,
I broke the screen of my beloved Mi 10 Ultra, bought a new one from china, waited a couple of weeks, got the new display, gave it to a local repair shop to change it. Got the phone back.
I knew that the under-display fingerprint sensor must be calibrated, so I went to Settings - My Device - All specs, clicked a couple of times, got into the CIT menu, found the "fod fingerprint calibration" tool under "additional tools".
When trying to calibrate (I saw a couple of forum threads about this calibration in general) I get the error messages:
1. 1513 High brightness incorrect - I think that's a general one that indicates I am not doing it correctly. Many people in the threads I read have the same issue and have explained ways to avoid it.
2. 1001 Out of memory - whenever I do everything right, just like explained, I get this message.
Is the partition where this info is stored out of memory? What is the problem, what should I do?
I have an unlocked bootloader, the latest version of a xiaomi.eu ROM (12.5.8 stable), non-rooted phone.

Maybe we bought from same seller because it happend the same thing to me, my only hope is to buy a fingerprint calibrator in aliexpress.
Annyway it is my first time with a screen not calibrated. i Asked other stores and they say it comes ready to use, so i am not sure.

There are many guides on youtube and threads on forums about calibrating and you don't need the tool.
P.S. I got mine from "ShenZhen KingCrop LTD Store"

Yes.. same seller.
I did triy Several times with a rubber with the same dimensions of the tools sold on ali.
Have you managed to solve it annyway? I Will try to find a store that has the calibrator. Otherwise i Will think about buying the tool

I think its a software and not a hardware problem. Many managed to calibrate without any special tools. I am still unsure how to proceed. Will write here if I have more info or if I managed to calibrate.

[Q] Display issue: bottom third ghosted with repeating lines

Received the phone yesterday afternoon and everything was great for the first three hours. After updating to the latest version and reinstalling apps from Play, the screen flickered and started ghosting a line of pixels stretched vertically over the bottom third of the screen (images and video below). It doesn't appears to be a hardware issue as the ghosting moves with animations, but it does appear during boot as well. I've factory reset without any difference, and have flashed the current firmware images (cm-11.0-XNPH33R-bacon-signed-fastboot) without any luck.
Booting
Notification drawer
App drawer
Video
Any ideas?
EDIT: I didn't have my brightness all the way up; the issue persists during transistions.
Sorry about that, you can try RMA. If it's also in Fastboot mode, you have two options: a) Write OnePlusOne and ask for repair(tooks long!!) b) Buy another phone.
You should try a custom kernel. As the stock kernel for 33r doesn't have the display commits that custom kernels have. I recommend Franco kernel. If the problem persists, then I'm afraid you'll have to RMA.
It is surely hardware.

mine too.....
Got mine 5 days ago and was in the middle of a game last night and the exact same thing is happening..... I put in a request for an RMA already but the whole process takes about a month from what i have read.... Didn't see a similar issue in a search of their forums but it is interesting that our phones came from the same batch likely and have the same issue....grrr

So I am debating filing a paypal claim. Reading the reports of the RMA process on their forum I am wondering if I will get a functioning device within the paypal buyer's protection timeframe. After several emails and pointless software fix attempts back and forth I finally got their support person to say they would forward me to an RMA specialist... but who knows how long that will take and given time frames I think it is very likely the 45 days will run out on 10/5/14 before I receive a replacement device. Any luck on your end?

Bad display issue with horizontal lines

Good day my friends,
my OPO from the very first batch in early june 2014 works perfectly. My second One, bought in september 2015, worked also very well. Until yesterday when I noticed that the display is completely full of horizontal lines, all aligned with the same space and the same size.
I thought it could be a problem with CM13 and updated to the latest release, but the issue persisted. I updated to the latest firmware because it made a lot weird stuff in the past - nothing changed. I read about some DPI problems when setting up a custom DPI in settings, you should set the same DPI in your build-prop. Did it and nothing changed. Finally I switched back to the CM12.1 release candidate from november 2015 and .... the lines were gone. I was very happy, but confused because it seems I was the only one having this problem.
2 hours later I was randomly checking my phone... and the lines were back. They started to get visible alongside the upper edge, in the statusbar region. After some time the whole screen is full with lines. After some time with display off there is a big shift and you can see everything double (unfortunately no image of this). I got the doubt it may not be software related and made a screenshot and sent it to my other OPO. And yes, there weren't any lines. So I think it is indeed hardware related, but I was not able to find something similar. Many results for this big line at the bottom which occured in late 2014, but nothing similar to my problem.
Before asking for a RMA I'd like to post this here, maybe someone knows what is wrong. I really hope it is not hardware-related and I can refuse to use the (not well working) RMA and support of OnePlus.
And NO, my device didn't fall down or something else. To be honest it isn't really in use, I just use it an hour a day
I made some images for you to see my problem. Maybe you saw something similar on the internet. Thank you in advance.

After some further investigation I found an angry comment which states "horrible horizontal lines". Moreover it seems to be clearly a hardware defect when a LCD panel shows lines..
Go for RMA, faulty connector pins. Maybe from the factory, maybe from yours. Higher air moisture can produce chalk on the pins too, even while they plugged in
hello fiz:ik,
can you please tell me that how this issue was resolved? as i am having exactly same issue with my OP3T.

U11+ Backlight bleed.

As title says, the backlight started shining through on my U11+.

It happend today, i was on my phone. i put i down to go get something to eat and when i came back the bleed came. it's around the entire screen.
i haven't contacted HTC yet because i wanted to ask you guys and get your opinions first.
i haven't dropped it, i haven't thrown it after somebody. i've been looking after it.
Sorry for the unacceptable quality on the picture, it's taken with my work phone.
That's not good. RMA it if you can.
Did you get yours repaired? My u11 plus just did the same thing today. I am wondering if too much squeezing the edge sense warpped the screen.

It happened to me too: I was watching a film, checked phone and it presented the same symptom, but in always on display. Rebooted and same problem. After a little time (just 10 minutes or down there).
I am using edge function and it is no longer happened .

I think the last time it happened to me was in January.
It's a bit bizzar that it comes and goes like that, I still haven't figured it out what's causing it.
But it doesn't seem to be a problem any more so I'm not worried.

FRP locked SM-G930w8 ( disabled OEM unlock on custom ROM )

Hello all,
From what I can tell XDADevelopers is the best place to ask stupid questions - because I'm noticing with how much time I've spent on here trying to solve this problem that everyone here seems to be particularly helpful! However, I have spent way too much time trying to solve this myself, so this is my last ditch effort before I go and buy myself a new phone, haha. If anyone can get this phone working again for me I will PayPal, send some BTC, or eTransfer ( if you're in Canada ) for your time!
So here goes:
I installed an 8.0 Oreo Superman ROM ( I don't remember the exact one I flashed - IIRC it was this one but I'm not entirely sure, but it was working really well and I was extremely satisfied with how everything was working ). Now I did this a while ago and I've been extraordinarily busy lately so it's been a while, so forgive the lack of detail. I was trying to install some sort of application/feature through Magisk Manager and it wasn't working as expected so I did what in hindsight what I know now to be an incredibly stupid idea - which was to disable OEM Unlock and disable developer options and reboot hoping it would get whatever I was attempting to install working. Instead I was greeted immediately to the following bootloop upon starting the phone again:

( here's a direct link just in case since the thread preview isn't showing the image for whatever reason: https://i.gyazo.com/1a8af44f100198c70ef9ebfc98fea374.jpg )
I'm unable to boot into TWRP and Odin/PC does not recognize the phone at all. I've tried on multiple computers, different cables, etc. My other Samsung S7 has no trouble being recognized by my PC & Odin as well as Samsung Kies, so I know it's not a driver issue. I only have the IMEI engraved on the back of the phone since I have long lost the box that had the SN on it, which might allow me to reset it through Kies as far as I understand. I am starting to think this is well beyond my capabilities to fix, or the phone could potentially be completely bricked. But again, that's why I'm here asking for advice.
I have tried my best to solve this on my own but I simply don't have time to keep working on this - so like I said, I'd be willing to pay to have someone attempt to come up with a fix for this issue or at least tell me I need to go and buy a new phone - though, ideally I'd prefer the former, haha. If the phone is toast, I was thinking of getting a lightly used Xiaomi Mi Mix 2 off Kijiji or Ebay or something - but if anyone has any recommendations for an alternative I am open to that as well, but I like the bezel-less design and the fingerprint reader, but ideally I'd like an OLED and wireless charging.
Anyways, hopefully someone on here has a solution or at least tell me with 100% confidence that I can safely toss this phone and I will keep my fingers crossed....
Thanks guys - any help would be greatly appreciated.

Question Corrupted firmware software

Purchased a sm-s908u 1tb model from Facebook marketplace earlier and on getting it home noticed it was very sluggish
Factory reset and hardware reset and noticed that non of the Samsung one ui settings were available in settings.
Then realised that there was no one ui elements at all! Seems to be badly running a vanilla android!
What are my options?
My first thought was to download firmware from samknows and hope that it fixes this very odd issue!
The phones still under warranty so I could always go down that route.

What phone is that supposed to be? Looks like a clone
It's not supposed to have rounded corners, you've been scammed
Nah its legit, the IMEI codes on the phone match with the box
I'm sorry it's fake it's not even the proper settings menu or anything

Scammer know how to do that. It’s all stolen, or faked. You have been scammed. Unless you can return it, your money is gone. if you try to use the warrant, you will be told the same thing.
another way I know it’s fake is a lot of these screens are clearly fake, not something Samsung would create, very ugly too. Look at the updator. Obviously fake. The toast in the second update picture has a grammer mistake too. And so does everyhtig in the updator. Read it again. And Google the real Samsung update screen. And real Samsung start up screen.
Can you get into recovery? What does it look like? If it really is legitimate, you might be able to load an official firmware, but who knows. What provider are you using? Are you using an e-sim? Says you are using slot 2.
The screen on a real S22U will be edge to edge, so I am afraid the others may be right.
100% fake.
Sorry mate
Don't order things like that from Facebook marketplace bro, that looks so fake
The welcome screen looks like Note 4 or 5. I'm sorry this happened. I don't know why people buy cell phones off Market
"The current version is the latest, not found the new version!" is the kind of broken English you would find in a fake phone.
And the SM-S908U only has one physical SIM, the other is eSIM.
Facebook is not your friend. Bad people reside there.
hello friend odin recognizes your cell phone if it is not false
Dial these two codes and see what happens
