Hello,
I’ve got the same device, and I m about to run 4.1 of the OS version. (android 13) 
I still have issues with sounds codecs every update out of 2 Sony Xa2: videos in slow motion that breaks video playing. 
What’s the best version OS for this phone ? I don’t believe Iode 5 will suit my phone model, and I’ve also no need to buy a new phone. 
Thx
