Don't forget to back up your data before you proceed.<BR /><BR />Open PC companion -&gt; Support zone -&gt; Phone/tablet software update -&gt; Repair my phone/tablet (blue link style). Follow the steps given, do not connect your phone until prompted to press volume down while plugging USB cable.<BR /><BR /><A href="http://www.sonymobile.com/gb/tools/pc-companion/" target="_blank" rel="nofollow noopener noreferrer">http://www.sonymobile.com/gb/tools/pc-companion/</A></P> Wed, 10 Jun 2015 08:12:01 GMT https://community.sony.com.mk/t5/xperia-archive/xperia-e-4-respond-slow/m-p/3358404#M470320 Qatrium 2015-06-10T08:12:01Z
