The Motorola Droid is not vibrating on incoming SMS. When you enable silent mode on the phone there is only a green light that indicates that you have received an SMS. Even if vibration is enabled.
I know this issue has been posted before on this forum among other android forums because I did a bunch of searching before posting this problem. No one out there seems to be coming up with anything short of going into the messaging options and enabling vibration.
On the Motorola Droid you can goto Messaging -> Settings -> Ensure Nofications is checked and Vibrate is checked. This setting should mean that when you receive an SMS you should receive an audible as well as haptic feedback when the phone is set to vibrate. The problem is at least on my phone is that I only get vibration on incoming calls and I receive a blinking green light when I get an SMS/gchat/MMS. I don't even get vibration on SMS/gchat/MMS when the phone is not on vibrate only and is set to ring even though that is what the vibration option says that it should do (vibrate as well as ring).
When I originally discovered this problem I figured that it was just a software problem and nothing that I could do about it until one day at work. I work with several Motorola Droid owners and when I approached them about this issue I got replies like, "what problem?" Specifically, I approached 2 other people who have the Droid. One who got theirs at launch with me and the other who just got theirs a week ago. The latter is having the same problem that I have. No vibration on SMS. The one who got theirs at launch vibrates like a champ when he receives texts. It rings + vibrates when the ringer is on and when its on vibrate it vibrates on txts. I went through his entire phone to verify all settings were the same and they were. He had nothing configured differnt from my phone. How can this be?
I know it's not a hardware problem because the vibration works on phone calls, but how can one person's work and another not if they are running all of the same applications and have their options set the same. I started to switch out my phone for a replacement, but I wanted to get some feedback. I looked through the notes for the Dec. 11th update and this isn't listed as a problem being fixed. Whether it does or not we will just have to see.
I came across a temporary fix that I have been running for several hours now called Missed Call. It allows me to customize the SMS nofications and get the vibrate + ring when the ringer is on and the vibration only when the phone is on vibrate. The only problem is WHY DO I NEED TO RUN A 3RD PARTY APPLICATION TO DO WHAT THE PHONE IS SUPPOSED TO BE DOING ALREADY!!! This application runs at about 4mb of RAM which I know isn't a lot, but still. This functionality is built into the phone.
What do you guys think? Anyone seen any other ways to fix this issue? Also, don't forget to vote in the poll at the top!
