Application always not responding

[MoNaz]

Just bought my sony XA1 two weeks ago and I've got some problems with it. 

My application always no responding when i use it. Moreover, when i use 'Live' on instagram it just live for 2 secs and then not responding. I have done factory reset and uninstall the app. But this problem keeps running.
