I mean, this one is on me. I bought Poco X3 Pro knowing damn well it's plagued with issues. But €188 for phone with Snapdragon 860, 120Hz screen, big battery, stereo speakers, headphone jack and IR blaster 1 and a half years ago? Hell, that sounds too good.
And yes, before you ask, I have tried turning it off an on. Also resetting both from settings and recovery.
I once had an Asus Android tablet. Absolutely loved that thing, until it needed to go in for warranty repair. Asus, for me, remains the absolute worst company to deal with for warranties.
Not only did they NOT fix any problems, but it would come back with more issues than when I sent it in. At one point, they didn't even bother to snap the screen in place, so I could see into the tablet (you aren't supposed to!).
They screwed me around over and over until the warranty period expired, then they ghosted me. Unbelievably bad service.
Last Asus laptop I sent off for warranty screen replacement came back with a lower resolution screen off a lower end version of the same model. By the time they returned it the warranty expired and they wouldn't fix their fuck up. I'll never spend money on their products again.
If that happened in Europe, that's illegal. The warranty period is suspended while your product is away for warranty repairs. Little side note, that only applies to the legal 2 year warranty protection, which is between the buyer and the seller (which is often not the manufacturer).
I had the second gen nexus 7 that seemed to pick up what was a common issue with the power button (something essentially came unglued or something inside and it'd stop working). I sent it off for repair and they wouldn't fix it because it was 'water damaged' (it wasn't) and they wanted something ridiculous like £75 for basically popping off the back cover and stopping all work.
Robbing bastards Asus will never get another penny out of me.
I recently took my Pixel 6a in for screen repair; somehow, water got under the glass and caused the whole thing to glitch out in a way that looked like I spilled black ink all over. Really bizarre. Anyway, I picked up the phone and visually inspected it - all was good, so I took it home. They said they tested it, I took their word for it.
Turns out they destroyed the NFC antenna, disabling Google Pay for me. It took me almost and month and several emails to corporate, but they ended up fixing their mistake.
Point is, this very well may be the fault of the repair people. I'd reach out to them first.
As a repair tech, this can happen really easily. There are sometimes like 2 dozen cables that need to be disconnected and perfectly reconnected for every function to work. Additionally if they don't have a proper testing software it's fairly labour intensive to test and it can eat deeply in your margins. Some cheap businesses won't bother testing beyond turning it on and just letting the customer figure it out and deal with it then.
For example at my work we barely test sub 100$ computers. The amount of time to , refurbish, wipe the drive, put it into stock, keep track of it in accounting and shipping it already makes it barely profitable, having to throw in another and hour to half an hour of additional testing can easily make the computer a loss for the company assuming it sells at all.
I absolutely understand; I used to be a repair tech for Sprint. That said, screen repair for the Pixel 6a doesn't even require the back to be removed, so I think it was more an education issue than anything else. I don't think it was malicious at all, but shortly after I noticed the NFC issues, the back fell off and I saw they'd cracked it pretty severely and stuck it back on with double-stick tape. It was less the crime and more the cover-up that pissed me off.
If it was a motherboard replacement, it's entirely possible they missed connecting the cable for the camera entirely or just didn't get it fully connected and is loose.
It's possible (the partially connected bit) since I previously got an image from it. Kinda. The camera app still didn't work, but CIT test menu gave me image with only small hint of color.
Edit: On the other hand, all 5 cameras don't work, which is suspicious. Maybe some calibration?
I really preferred it on the right, too. It was the default on my Galaxy. But I have a Pixel for work and it doesn't seem to let you choose which side the back button is on. I can't stand to have an inconsistency.
The camera module might have gotten detached, but of course we can't be sure with just what you showed here.
Not asked, but honestly I've owned a Poco X3 NFC for 3 years now and I had to send it recently to repair due to a shorted fingerprint sensor. But until then I had no issues.
this is why Apple is worth the money. they once broke my display cable while doing a battery replacement and gave me a new phone on the spot for free. the quality of service is unmatched.
