A55 weird monit on a lock screen

[Arminox]

Hi, 

I have a question, after last update sometimes my a55 says that it cannot control usb device while screen is locked.
It states that on a locked screen right under touch id.

The problem is that right at the moment when that pops up, no usb device is connected.

What can cause this?

Hello @Arminox and may I extend a Warm Welcome to the Samsung Community Forum 👍 

This sounds like maybe a glitch. 🤔

And if necessary > Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

If i can be of any further help please don't hesitate to ask  😎

Seems to be a bug in the update, I have the same. Unlock phone to use usb device. Since september update.

I managed to get to the core of the "problem" using chatgpt *rofl*.

It is just another layer of protection.

After 1 hour of phone being locked, phone itself block any usb communication.

Settings - Safety and privacy - (Scroll a bit down) More safety settings - Block USB connection after lock( Im using polish GUI so translations may be a bit off)

So its not a bug, its a new feature which is on by default I guess

But that still doesn't explain why it is displaying this message on the lock screen when no usb device is attached.

From my point of view that is still a bug.

If a device is attached it should be displayed, Not without a reason.

My 2 cents.

No no no, device just states, that it is no go for any usb device to be connected. Message might be a bit misleading but it just informs user, that any device connected from now on wont be able to make connection if device will not be unlocked

[RobertA55]

The device should show the owner information like it was before.

So yes it's a bug.

October update fixed the bug.
