Totally agree with your tips, FixerMike77! The airplane mode trick has saved me so many times when I want to peek at messages without letting the sender know 
. One more thing I found handy (and didn’t even know about until recently) is using monitoring apps like Eyezy (https://www.eyezy.com/) if you’re managing another device and need to check messages discreetly. It’s pretty user-friendly, even lets you monitor social media, and great if you travel a lot and need flexibility. Thanks for sharing those tricks—super helpful!
