there is no unlock or lock sound like the desktop version. Maybe you are going to add this sound in the next version?

Hey @Panagos. Thanks for getting in touch with us and for the feedback.
We don't currently have plans to add sound cues to 1Password 4 for Android. However, I'll go ahead and forward this to our developers for their consideration.
Thanks and let us know if you have any other questions!
