My US version has none of those issues...in fact it works great all the time! YMMVUS model updates are running months behind. I'm starting to think that this phone has serious bugs and Sony would rather that this model fade from memory ASAP. Everyone complains that YouTube pauses and unpauses itself. Many phones rebooted constantly after enabling fingerprints with the original firmware. I don't think it ends there.
I'm getting weird touchscreen and fingerprint reader behavior in several apps. OsmAnd~ causes the phone to constantly unlock itself. The phone unlocks itself when the fingerprint reader is bumped at least twice a day. The lock screen is constantly getting stuck on despite all my efforts to adjust settings to keep it off. Video playback causes random screen touches. The quick settings tiles sometimes don't work or self-trigger if they're opened while the phone is locked. The screen wake, notification sound, LED flash, and the actual notification are so out of sync that I don't know what's going on. There's also the mystery of SA 5G being disabled for all US bands on the US model.
Overall the phone is a mess.
