I have an issue.
On the S25+ device, push notifications appear at 5-10 minute intervals on the lock screen, or the push notifications do not ring, and when the lock screen is unlocked, push notifications come all at once. I wonder if this is a known issue in the S25 series and if there is a solution.
I suspect it is a problem with the user device settings (battery saving mode, notification settings), or a Doze issue.
