Hi all, just a little wrap up, I managed to put FlymeOS 6.2 on the phone finally.
I wanted to try the last Ubuntu build but unfortunately I couldn't get it to work, not sure why.
Someday I will get back to it but as of now i need android and wa basically.
I'm a bit unsatisfied with this phone, it's always warm and that does not help the battery which dries out fast. I wondered if that could possibly depend on un-optimized drivers on Ubuntu, it doesn't, the exact same thing happens on android, it's a hardware problem i think. Also the display is very good, big and bright but it's consuming a lot, that doesn't help the battery either.
In the end I will have to try it out and see if it lasts enough for my habits.. my hard earned money saving could last little time, sigh
Another time, thank you all for all your advices and help, without it i would still be trying (and swearing).
See you soon,
Sandro
