Slow phone

[Nik87]

Phone is very slow, always have a android notification, says that I need to finish setting up my data on my Xperia click on it and nothing happens. Is there something that I can do to fix this? Phone just seems like there is something wrong with it

Just do the usual things you can do.

- restart (better?)

- startup in safe mode (same problems? If no then a self installed app is causing problems))

- goto bottom of page and tick xperia support to find if there's something helpfull

- open the support app and find out

Success finding out and do come back if you cannot resolve the problems.
