When FRep2 does not replay touches but shows ‘Finished’ in Precision mode, please refer followings.
In FRep2 app, open 
Navigation menu and choose 
Calibrate Input and follow the shown instructions. It will register and analyse the touch signals to switch the replay type for the touch input device.
If Calibrate Input is not in navigation menu, it has been already done, so see next section. If you want Calibrate Input again, you can open it from Options.
In FRep2 app, open Navigation menu and choose 
Options – Precision Mode Settings, to change Use hover signals. After the selected option matches the type of touch input device, the replaying touches will work.
* ‘Auto’ will choose the type from the result of Calibrate Input.
(Confirmed on Xperia Ace II, Android 11. Use hover signals: Off)
FRep2 crashes on replaying records or sequences.
From the reports on some specific environments with Android 8 and 8.1, the notification popup (Toast) fails to be processed by Android OS (ref. StackOverflow). Try setting Notify Replay Process: Do not notify in Options – Notification Settings.
