Somehow my A2109 thinks it has a mouse attached, and there is an annoying circle pointer on the screen which behaves like a mouse and not like my finger. Also, since it thinks it has a mouse, I can't use the onscreen keyboard without pointing at each key with the "mouse." I've toggled every setting imaginable to try to get rid of it to no avail - there is still a setting in the language input for mouse/trackpad pointer speed (but no option for disabling it). In desperation, I did a factory reset, but sure enough, when it rebooted and asked me to choose my language, there was that damn circle taunting me. Is there some way I can either disable this mouse function or start over from the ground up and reinstall the ROM? My technical skill, while not very great, was enough to follow the directions on this forum to root the device oh so long ago (all of those instructions are now fuzzy). So, feel free to suggest something of similar difficulty if you think it would work. I hope you are all well and, unlike me, experiencing few technical catastrophes in your own lives!
