Hi,
I cant open my FB app in phone: it just shut down hemself! Comes also sms, that login was done. My action: I push on app, phone's desktop goes black and after a few seconds it shut down and I'm on beginning again. If I have some FB notisfications, I see them (you know - numbers in red sircle).
What I have done so far: have changed password, have done phone's factory reset, uninstalled and reinstalled app, nothing good so far

Phone: Android 4.1.2 and up to date
Any suggestions?
