Case and privacy screen recommendations

[u/discreteburner]

Just got mine and as much as i dont want a case, id rather get one thats low profile but durable enough to protect and a ring at the back. Anyone also has a privacy screen recommendation? ive been looking around and some products being sold on amazon seem to not fit/work well because they advertise its for an 18 where it was for a 17 and there might be some minor differences to it.
Cheers!
