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.<BR />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? <SPAN class="lia-unicode-emoji" title=":confused_face:"><span class="lia-unicode-emoji" title=":confused_face:">😕</span></SPAN> it's unusable at present Tue, 02 Dec 2014 21:57:31 GMT https://community.sony.rs/t5/xperia-archive/phone-suddenly-sloooow/m-p/3342575#M461006 lyllola 2014-12-02T21:57:31Z https://community.sony.rs/t5/xperia-archive/phone-suddenly-sloooow/m-p/3342576#M461007 The problem might be the avg app, I had a lot of issues with that app, uninstall it nd check again Tue, 02 Dec 2014 22:16:54 GMT https://community.sony.rs/t5/xperia-archive/phone-suddenly-sloooow/m-p/3342576#M461007 Uliwooly 2014-12-02T22:16:54Z https://community.sony.rs/t5/xperia-archive/phone-suddenly-sloooow/m-p/3342577#M461008 You can also boot on safe mode<BR /><BR /><A href="http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008#U348008" target="_blank">http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008#U348008</A> Tue, 02 Dec 2014 22:17:49 GMT https://community.sony.rs/t5/xperia-archive/phone-suddenly-sloooow/m-p/3342577#M461008 Uliwooly 2014-12-02T22:17:49Z
