I use the stock xperia keyboard on my Sony Xperia U. But I have many glitches, when I start typing, sometimes the phone doesn't write the letter that I tapped! And when typing I usually get normal vibration on key presses, but when I have a problem, the key I tap doesnt type and I feel no vibration! ! Help me get my keyboard normal again please!!
Yes I am also facing similar issue. Sometimes the letters do not get typed even after pressing them. In fact recently, the letters and numbers especially on the left hand side (for eg. a, s, q, w, 1, 2 etc.) reflected this problem more. This issue was also faced when I was playing a game, the part of the screen which I mentioned above was unresponsive somtimes. So I thought that it might be my screen that is not responding to the touch. Please confirm me if you are also facing issue only with the keyboard or during some other operations as well.
saurabh i'm facing the exact issue but i doubt this is an hardware issue.
i think it's because of low availability of RAM
restart your phone>>> 'Force Close' some apps and try again..
If the tips above from other users won't help you can try to perform an update of your phone's software. 
You can easily perform it with our program Sony PC Companion, available for download from the link below.
