Hey Guys, I noticed last week while in Sunny Florida that my Jet Black 7+ in an APPLE Silicone case when outside taking photos the screen dims to very dark . Restart the phone and its OK for a few then back to dim then ok again keeps toggling back and fourth.. The phone was not sitting in the direct sun either.. Is this a common issue? Are the JET BLACK or Matt black more prone to this because of the color? My Wife has a RED 7+ with with a clear silicone case and it didn't happen to hers. Thanks for any help.
