Hi guys, my UMi Plus is on Android 7 and the rear camera is slow to load and when it does is has a blue, black or red screen with flickering lines. I have performed a factory re-set and still the same. I see that other users have similar issues and it's recomended to flash the rom. I am a little reluctant to do this and am worried bout doing something wrong. Is there a YouTube video available as a step-by-step guide for those who need a bit more help with this procedure?
