I noticed that if I disable the vibration from the quick menu that appears when using the volume buttons and then re-enable it, the vibration starts working again. Unfortunately, this procedure doesn’t solve the problem permanently, as it will reoccur later. I need to figure out if it’s the “Do Not Disturb” function that’s triggering the issue.
No vibration for incoming calls
On my NP2 the vibration for calls generally only works when I select one of the pre-installed ringtones like “ripple” or “radiate”. Quite annoying.
not the the incoming call vibration, but the entire haptic feedback is dialed down on my phone 2. I liked strong feedback that i got from realme and oneplus phones and it would have been better if nothing had given us an option to control the intensity
JoelV bro first check setting then type your question here?

Satish Kumar The Nothing Phone (2) has no intensity slider for vibration, never had one.
Coldpaw people have a habit of spreading fake information. Nvm
Satish Kumar Phone 2 doesn’t have that feature “bro”.
JoelV Okay.

Hey Guys! I don’t know if you have already solved this problem or not, but I encountered the same problem and it happened when I copied data from my previous Android phone to my Phone 2A.
What I did was search up the option “Default Caller ID and spam app” in the settings and changed it to my default caller app.
Previously my phone vibrated for calls only when the option “Notification Vibration” was enabled. SO I think the issue was that the phone didnot register the caller app as a caller app and considered incoming calls as notifications instead.
I hope this helps
HarshaVLPR Sounds logical for me, but I had no chance to give it a try, maybe it’ll help other Community members
