I have android pie 9.0 -.352 and this version have next bugs:
1) xa2 ultra cannot connection (by cable type-c) with my dsx-416bt in Android mode, only mtp mode .on 8.0 it works fine.
2) notification menu have ugly black space on top, why Sony can't adapt such trifles?
3) camera quality in 9.0 is lower than 8.0
4) the worst sound quality among smartphones Sony that I heard. I have Sony wt19i, c3, xa ultra, l2, xa1 ultra and all that smartphones have good sound quality with surround sound and EQ working properly, they have tuning for headphones (if check sth30 you have surround sound ) on xa 2 u sound very bad it haven't surround, haven't general picture, all frequencies who in wood who on firewood. Sony I will be fan your smartphones all the time but you spat in my face. I will not buy the next smartphone from this company
