Restored phone to original factory settings on 22nd November 14.Today I downloaded WhatsApp from the Play Store(and it installed correctly).
After entering the phone number, WhatsApp has been stuck at the Initializing screen. I tried clearing the Application data. Reinstalled the app but to no avail. It's been stuck at the initializing screen for 2 hours now. Installing via the APK didn't help too.
I'm using a Samsung Galaxy S3 and have 4170 contacts (could that be the why the reason why sync is taking so much time?).
