Weak/No network signals

[FahadHabib1]

Hi

I am using Sony XZ3 for around 15 months on O2 UK. 

For last 4-5 months I am struggling to get good network reception. Changed sim card as well but no luck. I put my sim in my old HTC phone and not had any issues for 2 weeks. What is possibly wrong with the phone or network? 

Screen shots attached via Net Monitor Lite app. Why it shows WCDMA connection on LTE or GSM sim? 

Thanks

Same issue on XZ3. Only around 40 minutes of network per day for the last 2 months. A Samsung a30s works relatively fine with 100dbms and Sony goes straight to "no service". In areas of 88dbms it doesn't come back. Tried that SIM on XZ3 phone with no luck. Tried Safe Mode, no luck.  I'm on latest 52.1.A.2.1. Same situation. Tried staying on 2G or only 3G and no luck. I believe this got bad with Android 10 since 52.1.A.0.618.

I remember they used to update baseband kernels on Z series some years ago. Please give us a better baseband. Was there a baseband change from .618 to .672?

Please help. Phone is useless. Thanks!
