These has happened to my ZE620KL after updating to the latest firmware (WW-16.0615.1907.105):
1) fast charging not working
- I am using original cable and charger. also tried different cable and different (qc3.0) charger.
- tried to charge in all mode (standard, idle (airplane mode), safe mode, idle & safe mode, turned off).
- no fast charging in all conditions above.

2) USB OTG not detected.
- tried different USB OTG Drives (some type-C and type-A with adapter, all of them are FAT partitions). none worked.

3) Unable to connect to pc for file transfer (only charge).
- tried using both original cable and other data cable for connecting to PC. also tried different laptops. none worked.

3) phone-unlocking by fingeprint lagged a bit. it was instantaneous before upgrade.

Please help. thanks.
