Sony Xperia – apps / brower problems

Hi
I bought a Sony Xperia phone a couple of weeks ago via Amazon and last night it started playing up – I kept getting messages saying “X has stopped” working etc. I did the switch off / switch on , took the battery out, even left it charging over night but it is still happening today e.g. the brower will work and then a message will appear “X has stopped working”. Ive done a system reset (not a factory one as I dont want to delete all the data), but is there anything i can do or is the problem just going to keep happening ?
Thanks
Answer #1
you should include complete detail about yours Sony Xperia type, and os version.. Try do..
full backup your contact, msg, and try use Helium for Apps backup (it more user friendly than Titanium backup)

check update for your os, if available, do upgrade to latest.
if you using Adobe Flash Player (outdate) uninstall it and try test your browser again. outdated Adobe Flash Player can cause this
