Pop-up confirmation window is unresponsive

[Kot-Begemot]

I have an Xperia X Compact (model F5321 running Android 7.1.1). A few months ago it started exhibiting a very unnoying problem. When I use an app and want to do something within this app that requires a confirmation, the confirmation pop-up window that appears is unresponsive, so I cannot either confirm or cancel this action. Examples:

• When I try to make a WhatsApp audio call, a window asking "Start voice call?" appears. However, it does not react to my touching "call" or "cancel", so I cannot make a WhatsApp call.
• When I go to Contacts and try to delete a contact, a window saying "Contact will be deleted" appears. However, it does not react to my touching "delete" or "cancel", so I cannot delete a contact. 

I have searched the Internet, but could find a solution to this issue. Any ideas will be appreciated!

Happy New Year!
