Your environment

• Ethereum app v1.18.1
• Device: Nano S Plus

Steps to reproduce

Enough to power on the device, start ethereum app, leave it aside for few minutes.

Expected behaviour

Screen saver should go on and device get locked, but usable after unlocking with pin code

Actual behaviour

Screen will turn black and device becomes unresponsive, despite connected to power

Logs

I dont have logs, dont know how to create them

hello @dnld23 thank you for your feedback

Do you encounter the problem every time? Because it hasn't been reported to us, and I performed the same test without any issues on my end.

Hello,

I narrowed it down today to following (I tried to disable screen saver):

When my setting is: PIN Lock 10 minutes, Screen Saver 2 minutes, issue happens always (probably after 2 minutes). Ethereum app needs to be running. If Ethereum app is not running, screen saver comes on and device locks later as it supposed to

When i changed setting to: PIN Lock 10 minutes, Screen saver: Never, issue doesnt happen. After 10 minutes, device is locked and PIN screen shows up. No issue here, works as its supposed to.
