Bad phone :(

1)  What a worst phone I bought pity me seriously the worst I ever used one bug goes off and other comes back. Recently can't give permission to the app when go to sd card permission through the app it shows nothing in recents idk why. 

2) YouTube videos sometimes slow down idk but it happens and its random.

3) Sd card checking for errors it always keep on checking for error in sd card and I can't use app in the meantime plus sometimes it keeps on checking for errors I have to restart the phone.

4) Screen flickering issue is still there I guess.

Other bugs you know it better.
