Lately my LG Optimus on the Straight Talk network has been doing all sorts of weird things. (Ex. flashing, closing a text message when i open it, contacts not receiving text messages i send, noises and flashing screen during calls, phone cutting off for no apparent reason whatsoever etc.) I have also seen, twice, apps on my home screen, different apps both times, one was 'DU Booster' with the android icon and the other was a Straight Talk icon that said 'Data Settings'. Both times I immediately long pressed and hit Uninstall and each time it stated that neither app was in my apps. Then when I was about to go to my settings/apps to check it out, they both just disappeared. Can anybody help me with this? And if so, besides just getting my device back to normal, can I trace this somehow to the person that's doing it, if it is someone remotely viewing my phones details.
