Quick Solutions to Infinix Hot2 & Hot Note Top Problems

I've been able to deduce lots of problem and solutions from the Infinix hot2 and Infinix hot note complain thread and I discovered that the listed questions are more paramount to a newly or existing Infinix hot 2 users. 
It's important to note that Android One interface is different from normal android interface therefore you do not expect the same functionality like coming with a default music player, video play, file manager etc.

It's also important to note that if you don't set up your gmail on Infinix hot2, you'll only do less from that device, therefore it is compulsory you set it up.
