I bought an Android phone in used from a friend. It is working fine but don't know there is something wrong. Some games run with lagging and sometimes it doesn't load at all. I wanted to know is there any way to know whether the phone has ever been rooted in past or not? I mean if it ever got rooted in past and then un-rooted. Is there any way to know that?
I am asking this because previously i had another Android phone, and i rooted it and had some problems with phone. When viber was running and call came, the phone got stuck (held) and i had to restart it else there was no solution. Later i un-root it.
That is why i am asking this.
My current phone is Huawei G610-u20.
