This One Phone Setting Stops Strangers Reading Your Messages Over Your Shoulder
Your lock screen is showing more than you realise, and the fix is two taps away.
Put your phone face-up on a table and a message arrives. There it is, the full preview, glowing for anyone nearby to read. Your lock screen might be quietly broadcasting your private life to the whole room.
Buried in your notification settings is an option to hide message previews when the phone is locked. Flip it on and you still see that something arrived, but the actual words stay hidden until you unlock the device.
It is a small change with a surprisingly big payoff. Nosy colleagues, curious strangers on the train, and shoulder surfers all get nothing but a neutral banner. Your conversations stay yours until you decide to open them.
You lose almost nothing in convenience. A quick glance still tells you a message landed, and unlocking is a fingerprint or a glance away. But the details stop leaking to everyone who happens to walk past your desk.
