    I just bought a new Oppo f1s and after a day I noticed that sometimes when I open my phone the lockscreen becomes so glitchy with gray and black static screen. I have to open and close the phone (sleep mode) a couple of times (around 3 to 4 times) before it goes back to normal.

    It usually happens when there are some notifications like text messages or FB notifications.

    I also noticed that it happens when my battery is around 30 or 20 percent

    This glitch already happend twice, yesterday and today.

    Is this a system/hardware/software error or a factory defect?

    Please help

    Whatever it is, back up your important data now, while you still can.
