Screen opening apps i haven't chosen or locking up
When i turn on the tablet there is a portion of the screen that acts like it has a stylus or finger pressing repeatedly in that area. if there is any link, app, video playing near that section it will open, without my choosing, or in the case of videos will keep the progression button on the same spot causing the video to get stuck in a certain area, sometimes i turn the screen on and it immediately turns back off. Is there a fix for this, what can i do to correct the issue?
