[SOLVED] Phone keeps vibrating



Hi there,
The issue is already solved, but I thought I’d drop this here since it took me a bit to figure out what was going on.
I noticed the phone was giving of a double vibration quite often and seemingly without reason. Tried a few things suggested from random android forums, but eventually found out that the vibrations were caused by the snyc frequency which is set by default to 2 min. Once I changed that the phone was behaving again.
Hope this helps anyone who runs into the same.


Hi @Carlos on which device did you face this issue.


Hi Manoj,
OnePlus 5t


Hi @Carlos
I have the same issue on my Redmi 3S.
Can you explain me the step to fix the issue please ?
Where am I supposed to find the sync frequency ? Is it account related ?

Thank you for your time,



@Carlos are you referring to the sync settings here …Settings icon >> User & Accounts >> username e account >> Account settings>> settings ( gear icon)


Hi @tomekl and @Manoj
As Manoj indicated, thats the setting, it took me a while to find it the first time
Settings > Users & Accounts > username /e/ account > Account settings > settings ( gear icon)
There i changed all the sync settings to once a day (aka 1440 minutes)


I had the same problem with my 5t.
It was the task synchronisation, that make the phone vibrate every 2 minutes.



Does anyone know why the phone vibrates at sync?
My Xiaomi Mi A1 started to do this yesterday.

Edit: I could solve the issue by going to Settings > Users & Accounts > username (webDAV)
(I’m using my own webDAV server, not the one from /e/.)
When i synced manually the phone did vibrate.
Then i unchecked calendar, contacts and so on. I did one manual sync and then i switched them back on and synced again manually.
The phone did not vibrate, so the problem is solved for me.
