The only sad true here is that in 3 years since Xperia 10 II entered into OpenDevice program the hardware support is still not complete. Probably because people here are more concerned to close loops than deliver a usable product. 
- XA2 users still should go through a complex procedure for activating A-GPS
- X10 III users complaining that the battery is draining out too quickly
- X10 II - I am taking care of them because I am one of them…
Would you help me in doing something useful or do you prefer plays with loops? The choice is your.
I barely have an idea of what I am dealing with because before 26th May 2023, I have never get into a smartphone but I was just one of billion that were using a on-the-shelf technology. Despite this, I managed to summirise a post-installation procedure that shrink the worktime from a week or two in one day.
At the moment there are at least 4 changes proposal that are waiting for someone that takes care of them:
- an easy deploy of the A-GPS config for X10 II and III (here)
- energy saver at 50%, 100% battery threshold and histeresys at 87% is too much, 85% at least (here)
- device lock adding 5/10/30/60 seconds, also (here)
- fingerprint reader and bluethoot awakening or a fingerprint restart icon/link in lockscreen (here)
Possilbly also these two:
- add an option for disabling the Android Support autostart and kept it sleeping/ready to start (here)
- add an option in the native broswer to let it keeping alive a backgroud tab that is doing some taks like playing music (here).
The first four are simple tasks that require few hours/days of a SFOS hacker and greatly smooth the user experience of everyone intersted in adopting SFOS with X serie.
It is your choice, it always been since 2004 four years before Android debuted.
