[Q] cannot answer call via screen
Hi , I am confused ,I can configure my s4 mini to answer incoming calls by pressing the "home" button ,and I can configure the phone to answer via "answer" voice command , all of the screen buttons appear to function ok , and calls can be shut down via the red "phone disconnect" symbol on the screen ,but for some reason I cannot answer a call (the way I want to ) by touching the "green" connect symbol on the screen ,it wont respond to touching in any form apart from the onscreen tremor you see when you tap the screen it simply wont work .
The phone is rooted and I have disabled just about everything related to data transfer , wifi,and internet , as well as uninstalling , disabling or hidind all other apps . the phone is to be used for text and talk only ,for my other half ,who has learning difficulties , its the cheapest way for her to get unlimited text and talk .
any help would be apreciated , thanks . graham
