I just bought a HTC sensation xe. I noticed the vibrate function wasn't working after turning the brand new phone on.
I decided to scroll the net looking for answers, and I came across this post. I've been a HTC and android user since the original HTC G1 and was getting frustrated because I couldn't understand why the vibration was not working. I looked at all the settings within the phone.
I then decided to drop my phone at least 10 times onto the carpet, and hey presto the vibration started to work. Sad but true. Thanks for updating your post, you saved me sending my phone back!
It looks like the vibration mechanism just needed a jolt! |
