I am unable to use any Famous Apps like - Gmail, Whatsapp, PayTM, Calendar, Antivirus apps, ram cleaner and many more apps Except few apps such as android chrome.
As soon as I am opening these apps then I am getting error "Unfortunately Whatsapp has stopped" OR "Unfortunately Gmail has stopped".
I am getting this problem from yesterday.
What I have tried:-
1) Factory reset
2) clear cache of gmail/play store/Google services.
3) Using updated version of play store/Google service/gmail/whatsapp/PayTM etc apps.
But unable to get solution till now. Anyone help me in this serious matter ?
