So I'm having this issue where after a while of using my phone, for an indeterminate amount of time, it will start freaking out on me. It will lag, Google play may not work properly, and most of all, the action memo from the air command simply stops working. Selecting the action memo command will bring up an action memo minutes after I click it. Sometimes it'll never pop up. The tale tell sign that my phone is corrupted is when I go to the application manager and all applications, I see 4 different action memo programs. 3 with the action memo icon of the pen with a squiggly line, and one that has an icon that says "Memo" with a yellow background. This problem is persisting through a factory reset and the device is completely clean with no apps, which means the ROM is corrupted. I have done nothing in terms of rooting the device or anything. I've kept everything stock and have only installed a few apps and games that I like and rearranged the screens to my liking. I have no idea what to do from here. This is the second Note 3 I've gotten from Samsung, but it seems I'm the only one with this issue. What do I do? Please, someone please tell me I didn't waste hundreds of dollars.
