My son has a Bionic that has had problems since the recent update.
First, it used to say "Droid" when he got text messages and now there is nothing.
Second, he uses speech to text when texting sometimes. Now it doesn't recognize him talking.
These first two things are about 50/50 chance they will work. When one works, you know the other will work. If he pulls the battery, they will start to work for a while, but will go out at some point later.
Third, the vibration doesn't work when you touch the screen. Used to vibrate for a second when you touch an icon on the screen or swiping to unlock or texting ( using the on screen keyboard ). This has not worked since the update.
Vibrate is turned "on always ".
