Bhaiyyaji is now unpadh/Gawar?

I think he was shown talking fluent English in many episodes before and now in today's episode he doesn't know to reboot his mobile and behaving like he never knew English😆.

Forget previous episodes, in the very same one he fluently not just pronounced 'personal' but spelt as well!
Chalo ek min ke liye let's beleive reboot is a technology thingy... But how difficult was it for him to grasp but pronounce it? 😛 😆
