LG G2 clock keeps running behind. For example yesterday the time on my phone was 33 minutes behind the actual time. This has happened to me several times. I tried turning my phone off and back on to reset it but that didn't work. I finally got the time fixed by going into the clock settings. But what is making my clock off? And is there a way to fix this so I stop having this problem?This is what I typically use to tell time so it being behind is not good.
