Mine seems pretty good but keep in mind that whatsapp/facebook/viber calls all these are VOIP , those are definitely going to be the clearest in terms of voice quality.
So the Internet signal is probably okay. Maybe the phone fault?

Which telco you're using?
Celcom. Never had problem serious like this before.

Mine is normal lo. It's clear and no signal loss. Maybe your location got bad signal or your telco prob or sim card problem.
Is there chances that the phone is faulty? Just ported from iPhone 6.never had any problem before.
