I tried searching for this subject but found nothing. Here's what happens... sometimes my phone gets very laggy especially the unlock screen and the internet is unable to load any pages. It gets to the point sometimes where i cant unlock my phone and im forced to turn it off and on again. But when im able to, shutting the wifi off and on again fixes it. when i uncheck the wifi box it'll say "unable to stop wifi" under it. any ideas or suggestions?
