    Hello. A few hours ago my phone (samsung s7) started to display some green dots on black background (only on black, no other colors) and green lines in gallery and camera (on black spots). It might be a bug or something...the phone was kept on my desk, near me, no damages, those green things just random popped up and i do not know what to do...the screen is not damaged and the phone is just 2-3 months old.

    Also those green lines are appearing only on the half left side of the phone and also those now appear on facebook, when watching photos there are some black edges above and below the photos, and the green vertical lines appear on them.
    Large number of green dots appear in camera too.

    Some help? What might be the problem? Sorry for bad english, im not a native.

    Photos here:

    Welcome to Android Central! Does it persist after a reboot? When it happens, take a screenshot and see if those lines appear in the screenshot image. (View the image on a different device, since it'll be hard to tell on your phone if the screen problems are still present.)

    If the lines don't appear in the screenshot image, then try Safe Mode: https://support.t-mobile.com/docs/DOC-30229. If the problem persists, then it could be a problem with the firmware or the hardware (i.e., the screen). In that case, I'd bring the phone back to the store and ask for an exchange. If it's too late for that, then contact Samsung for warranty repair/replacement.

    Added a few photos..

    The problem still persists after a few reboots. The dots and lines can't be seen in screenshots so i used another phone to catch a shot with em.

    I would contact Samsung looks like it could be the digatizer not working properly. You could try a factory reboot but I honestly dont think that would even help this. I know if that was my device I would contact them ASAP.

    That is what i will do!
    The only one thing that annoys me is that this happened suddenly, if it was done by an accident it would be different but i didn't do anything to the phone...i will get it to them.

    It could be just something became unseated from the board, it happens. I remember my first S3 had a bad charging port, second S3 had for 3 years with no issue.
