Smartphone repair

Hello everyone. I’m worried about my aging yet still beloved phone and I wonder if anyone knows a relatively skilled smartphone repair guy in Bangkok that actually helps me with my phone.

I had my phone at a random shop yesterday and tried to explain the issue which I’m pretty sure which part exactly is causing it. I was assured they know how to change that part and they would have access to spare parts. We discussed the price and the time I could pick it up.
I returned, the phone looked alright and they promised it’s working now (which I couldn’t verify at the spot). Turned out they did fuck all, probably made the problem even worse.

I love my phone and I don’t want to replace it just yet so maybe someone knows a place I can visit.

The phone is a Pocophone F2 Pro, in some counties sold as Redmi K30 Pro.
