Hello,
I just buy a m3s, and firmware is 5.1.5.1G.
No update available OTA

Should it be good to update to latest version Flyme 5.1.12.0G or an other one ?
Some screen are in chinese in my phone (such as flyme account for example).
And I don't find root access ...

And 2nd question : is the firmware on flymeos.com an international version or not ?

Thanks a lot for your help
