Had troublesome sp for a while. Did a software repair 3 months ago, much better, with the odd glitch. Last few days phone has been VERY slow and keeps going to blackout randomly. It's just used 35% battery in an hour which is unusual ( I don't do big things with it, just interent and email) I don't want to do another software update, it's only been 3 months.
I used to get it back to speed by Manually clearing all caches and stopping running apps. Now I have the avg cleaner which is meant to do that for me, but wondering if it is? 😕 it's unusable at present
