Whenever I text (in an app like Facebook or just MMS) and I hit the keyboard a little too hard or press the X key a few times to remove mis-spelled words, my screen size will expand and I can't continue typing. The text becomes extremely LARGE. I have to get out of that app or MMS and try again. For some apps, what I typed is lost and for some apps, the data is retained. Does anyone have this problem too? What can I do to prevent this? I have to type very gently to prevent it.
