I have a Samsung Galaxy S8+, purchased this month (June). I do not have any problem with Instagram videos or other pics, or videos and pics from other sources. Also, it does not have any problems when I type unlock pw. It goes right to home screen. I do not use face recognition, but definitely have not had your first two problems. If your porblems were happening with my phone, I would take it to your carrier store. Mine is Sprint and they have always been very helpful with phone problems. But, so far I have none and love this phone. My previous phone was an LG G4.
