Different Android manufacturers have their own firmwares with unique designs and features. In some firmwares, the contact picture appears very small in case of incoming calls. So the user might want a larger contact picture while receiving the calls. This can be achieved using the app Ultimate Call Screen HD.
Ultimate Call Screen HD makes the calling experience a bit more enjoyable. The user will get a full screen contact picture not only while receiving the calls but also while dialing the contacts. This app adds some additional features to the old fashioned calling style.
