Hey Samsung, fix your stupid screen lock for the galaxy watch 4. You have sensors that detect when the watch is on, I go to unlock the watch and guess what? It locks itself right back up. Then I have to unlock it again, sometimes I have to put my pin in like 5 times. Your stupid tech needs to be fixed right now. Stop making new phones and wearables and fix the stuff you have NOW!
surprisingly the I have not had locking issues even when the watch was flopping around my wrist ... I even tested the watch locking while the watch was lifted from my wrist ~1 in apart.
as long as the sensor detects the wrist within somewhere between 1-2inche distance it'll stay unlocked.
so then OP is possibly wearing a long sleeve that gets in the way of the sensor and the wrist OR has a tattoo that messes with the sensor (on Reddit it's easy to find people with tattoo note that watch isn't detecting the wrist) OR OP really does have an issue.
