After the recent Pie updates, can't help but noticed that my calls are frequently being dropped. This is most apparent whilst traveling in my car 😑
Didn't face such an issue back in Oreo thus am very certain it's due to Pie as never added new Apps or anything else etc. Anyone else facing this issue? 🤔
Hello. Did you solve this problem, please?
After doing a full factory reset, issue seems to have disappeared for now 🤔
Didn't the factory reset take you back to Google 8 Oreo?
No, a factory reset does not change the firmware. If you are on Android 9 then it stays on Android 9.
After Android 9 reinstall... same problem. 
Is the total reinstallation of the software sufficient, or should I still try to restore the factory settings? That's probably unnecessary.
Is it okay that I have reinstated my backup data after I reinstall?
Not sure what you meant by reinstall but if it's just installation over existing O/S then it's akin to upgrading. Factory reset does not just reinstall but does a complete clean wipe without any previous settings being retained. Hope that helps 😊
Didn't try that 🤷
After clean Android 9 instalation using SONY Companion (Software Repair) - dropped calls during first 24 hours
After Factory Reset (without data recovery) - It seemsed to be ok for one week. Yesterday I couldn't make a call. After restart yes.
