My phone has recently started to randomly detect taps in a specific segment of the screen, the placement is just right to trigger ads if im not careful My normal tolerance for ads is basically 0, so I expect a change on what gets shown to me until I replace my phone, which will be interesting, because ads I get shown are targeted to me pretty accurately From the location and other problems, I'm guessing the battery has swollen, so it will have to be pretty soon
