"Authentication is required. You need to sign in to your Google Account"
I have done following things to solve it but failed:
1. Removing all accounts and re-add them
2. Factory reset
3. Try opening my google account to see if it is blocked?
4. remove and reinsert SIM
Issues are persistent in every Google services namely Google Play, GMAIL, chrome etc.
I am on unrooted Stock ROM and pretty much stuck here.
