No option to recover password in Lenovo Tab S8 (S8-50) So I locked myself out of my tab and I can only open it by entering the password (which I forgot). There is no forgot password option where you can enter your google account to get pass the lock screen. The phone has a google account. Is there any way to bring up that menu? I thought all android devices had the Forgot Password? option
I had similar problem too. My solution was to connect it to the computer and did factory reset. If you have root than follow instruction on this link:  https://www.youtube.com/watch?v=tVJ7T2oC_Zs
ON SOME DEVICES IT WORKS EVEN WITHOUT ROOT ACCESS

Good luck! - Nik
