I can't update & can't sign in
I have Panasonic Eluga Ray 700. In our homw, we have 3 phones of the same variant. We couln't update & also log in with each accounts. I tried with microsoft account and also with google. There is no error code displays. But it just failes and stays in the old stage. More than 2 years I have been writing and trying. No hope. I feel, no body could help yet. I have to leave from swiftkey. But I love the app keyboard. That's why trying again and again. Is there any new ways?
