See if the bathroom is any different!
Something I noticed on the new plane last week, the gap between seats seemed wider than previous planes, allowing for "shoulder surfing". My iPhone 14 Max Pro could easily fit between seats in front of me, 3" wide plus the case. On a 700 the next day it wouldn't come close to fitting. Haven't flown an old 800/8 since to compare.
At first I didn't realize what the spring-loaded thing below was, but after the flight I realized it's to hold a phone upright in portrait mode.
