... Tells me Amazon to my Handy.Es ran daily faithful and liquid until last week, then it crashed and lettering apparently ran high only until "Xperia". Panic! Nothing helped, remove the battery, remove cards - the same.
The not entirely wrong much maligned software "PC Companion" Sony did not recognize the phone, the PC anyway (as a memory).
BUT: Miraculously features of PC Companion on a repair function! This has - as with a software update - after some being downloaded and updating the operating system loaded onto the otherwise unrecognized phone.
After inserting the card and signing up for Google this the rest of the software and also the address data restored, scary and disturbing but useful.
Function now even more fluid than before, probably stayed with the radical cure of some garbage on the track, the phone memory is in any case considerably less strain (All Apps, where this is possible, were already back on the internal memory shifted).
I must continue and hopefully enjoy for a while a cell phone me so that fits in my purse.
And Android 4.0.4 should for a while for those Apps sufficient that one uses on a cell phone, this screen size (Pebble running smoothly).
