Is there an Android app that prevents butt dialing and does not require many permissions?

When I hang up my phone, occasionally I slide my thumb over a contact and make an unwanted call. That is very annoying – for me and the person I called.
I want an app that slows the process down.

I found some apps called Call Confirm that seem to do what I want, but the permissions seem excessive.
Do you know of one that works and can be trusted?
