I have an old Xperia Z4 I bought in Japan I stopped using because the native OS is too slow.
>>109026138Japanese Xperia are different from international models and usually less moddable. RIP.
>>109026138If it used to be ok but the OS ended becoming too slow, then do a factory reset and it'll work like new.We all wish we could install lighter Linux distros on Android devices. :(
