I've been using titanium back up on my phones for quite some time. Upon getting the v10 in November I installed it on and all was good. Out of no where (and weeks after me disabling anything new on the phone) the second screen stopped working at the end of December. I tried unfreezing everything but to no avail. I eventually had to factory reset to get it up to come back. Since then I have tried to reinstall it twice more and the same thing happens even when I have unfrozen everything. I was also very careful the second two times to not touch any LG apps. It seems it's somehow corrupting a file, but it's very strange as to how or why it seems to be permanently effected until factory reset. I refuse to even download the app again as long as I have my V10 cause setting up my phone over and over is a pain in the ***, but I'm curious if anyone has had a similar problem or knows why this is happening?
