I have been using purity rom with elemental kernel for a long time now and never had any GPS issues until now. Started about a week ago, I would use my Google maps but would lose my GPS signal and the turn by turn never picks up signal again. It just becomes useless. I don't get what would make it do that. I've tried to clear data in the maps app and also I've downloaded android tweaker to update my GPS settings but nothing has helped. Any idea?
