Android is the new Windows. To fix this I find I have to factory reset a lot of phones. Sometimes you find a phone they used clean master or an antivirus so you uninstall those before you try again. If they balk at that then you move to a factory reset.
It's a shame this OS is following the same trajectory as Windows as to problems like this.
the notification says "LG back up update available.App must be updated before use" but the app is already up to date and i cnt access that function.http://s7.postimg.org/6j6mixqx7/Screenshot_2016_03_19_21_13_46_1.pnghttp://s27.postimg.org/bpc2f0vtf/Screenshot_2016_03_19_21_13_25_1.png
