So I got a LG Fusic. For some reason it kept vibrating every 2-5 minutes even though I had no new alerts/messages nor had any missed/incoming calls.
I found that I had to turn-off message reminders to get it to stop. A known bug in the phone for years now. I find LG cell phones to be low quality in general now.
- Menu (press MENU)
- Settings (press #)
- Messaging (press 6)
- Message Reminder (press 2)
- Set to off
You can still get notification when a voicemail/text message/etc. arrives, but you won't get reminders of unread ones. Better than the thing vibrating all the time and killing the battery.
