I receive text message, I'll see it once I press the home button, but never got the alert tone with vibration. This is intermittent, and happens with both iPhone and android senders.
Thanks for the update @Mmdrivard,
We can run a few tests together to narrow it down:
Let us know!
Once again on your Notifications, are they active for: Lock Screen, Notification Center as well as Banners?
Is your Do Not Disturb on?
Also is this happening for both SMS and iMessages?
Keep us posted!
Thanks for letting us know.
Can you please also confirm if the Do Not Disturb Settings is ON or OFF?
Also, can you reset the network settings and let us know if that changes anything: Settings - General - Reset - Reset Network Settings.
