i was recently trying to fix the charging port so I opened it up by taking out the 4 screws. I fixed the charger by gluing it back in place and ten put it back the ay I took it apart, quite simple, however wen I turned it on I noticed the screen now ad a peculiar rein tint to it tat wouldn't go away. it is really bothersome so if someone could tell me how to fix it, much appreciated.
