I have chinese phone phillips s562z using android 6.0.
Whatsapp notification not showing up when phone is lock or when i clear the memory.
I have try everything, from set notification, turn off battery optimation, set permission, turn off doze mode, reinstall whapsapp, install PNF no root, etc. Nothing works.
When i clear memory , i see there is no whatsapp active service in the developer option>running service. But when i'm not clear memory, whatsapp notification working only when phone is not lock/idle.
I found something, whatsapp notification come out when i open google playstore, and click share button.
Any idea how that happens?
