Hi
Is there is function any of single tap mode to answer and reject calls?
Due to lack of many physical buttons, most Andorid smart phones on the use of on screen buttons to perform actions in your app. Some of these actions require a minimal amounts of interactions, others require some additional steps. If there are certain things on your phone that you little easier to do, such as interacting with alarms and phone calls, then you should try activating single tap mode. https://panseva.com
Hi Ashish. Which Asus phone are you using? Check Call settings and Accessibility in Settings if there's an option for that. You can use 3rd party phone apps for that in case your phone doesn't have that option.
