I have been using my FP3 since December, but over the last month or so I have been experiencing quite random behaviours almost daily. For instance, when I am using Whatsapp or Twitter, and spend a bit either texting or scrolling down the screen, the screen would start not reacting and doing things on its own, such as: open chats/tweets, scrolling up/down, calling contacts, opening other apps (clock and alarm most frequently), disabling the wifi and setting the airplane mode… all on its own, flickering and without me interacting at all with the phone. To stop it I just block the phone and when unblocking it it would work well again although reacting quite slowly, but I’m having this issue multiple times a day now.
I have no idea what might be the reason for this, and I would like to know if there is any procedure to try to fix it or if I should contact Support.
I have the same problem. I bought my FF3 in januari but it only started a few weeks ago. It happened like 3-10 times a day, making is really irritating to use the phone. I did a full factory reset 1 week ago, since then it happened only once, on the same day I resetted.
