so new phone, everything seemed like it was downloading fine and putting apps on there like this crappy dragon game and sky sports, then as i tried another app you can see it starts to download, it then gets up to around 90% or fully downloads it then it just goes off like i cancelled it or says installing which will last for ages. I will then get bored of waiting and go on an app or something and then when i look back at it, no message to say installing so i think great its done.... but nowhere to be found and needs downloading again. sorry for the bad language but its pissing me off big time. need advise pls help.
