Performance is slow

[Notme112]

Hey there,
I'm really happy to found this app, its that what I want to code but yours is so good that I don't need anythto do it anymore. My question is, how can I improve the performace of the app? In my case, it is really slow (uot to 5 seconds for screenshots). Is there a way to improve or is it because of my system / device?

Edit: The Screenshot is captured nearly without any delay, but the buttons reappears only after this time
