My Droid 4 has a very annoying problem. Every now and then the physical keyboard will stop working. I don't know if I might be clicking something, or if it's a hardware issue. I'm not very phone tech savy, so maybe I am accidentally changing the input method. I have no idea for the life of me how to fix it however. It will be like this for about a week, then it will switch back and I can use the keyboard again.. only to switch back a few days later. The Problem: The keyboard does not type anything when I push the buttons. But if I type the letter "M" Google maps will pop up, if I type "G" Gmail will pop up, etc etc. Does anyone know the solution to this? Thank you in advance for your time!!
