Exclamation XT1955-4 display/ screen - turns black/shuts down/turns off randomly

I bought an MOTOROLA G7 Power, 64GB, 4GB RAM, Dual SIM, Black ( SKU: SMTMOTOG7POWBK ) from Europe, Romania - Product/Variant: ocean XT1955-4 64GB PVT1 on 17.11.2019 and today, after all this time, the display of my phone turns black/shuts down (but I don't think it turns off - see the explication below) SOMETIMES randomly when:
  • - I watch videos on Instagram, Tiktok, Facebook (not on Youtube)
  • - I see Insta Reels, Insta Stories
  • - I use Google Maps for navigating
  • - I get called on my phone number

The reason why I say that the phone doesn't turn off when I do the things about is because after it's on again, it has all the apps and tabs running. Also, I had a timer running and that timer was still counting even if the phone had the black screen.
The only thing that I've done different before the smartphone started to crash is to apply a magnetic car support on its back. Now, even if it has that magnet on the back, even if it doesn't, the phone still has problems. I've also throwed the phone on my bed a few times, took the phone to the shower with me and steam got on it (no water).

As a fix, I've tried to updated the phone firmware till the new Android 10 version QPO30.52-29), but that didn't fixed the problem.

How can I solve this MOTOROLA G7 Power XT1955-4 black screen/crash/shut down display? I don't want to change the phone because it still works OK and I wanna keep it.

Thank you!

If device is under warranty, you should apply for it.

as you supposed, strong magnet could make such problems,
and also make sensor faulty (sensor for phone case, to shut display when covered).

there may be many more hardware faults, but this one is most probable.

updating firmware doesnt help in such cases.

so, you can not solve that problem.

if phone is not under warranty, you should visit some professional
or authorized service repair center.
