Kyocera Rio E3100 is a feature phone that comes with a 2.8 inches resistive touch screen. The display requires a little bit more pressure in order for your touch to be registered, but, overall, it is responsive. As for graphics, they look colorful, but not as smooth as we would have liked because of the only 240 x 320 pixels support.
Its communication capabilities include a decent call quality, text, multimedia messaging and mobile email. Writing a text, however, can be quite a pain with this device. In the landscape mode, you have a virtual QWERTY keyboard that is cramped and has small keys. The people with larger thumbs should definitely look at another phone. In the portrait mode, you have a half represented QWERTY keyboard; you basically have two or three letters per key. This device is best used for its voice capabilities and not messages.
Rio has basic features, like: alarm clock, vibrate mode, conference call capability, calendar, stop watch, calculator, 500 contact phone book, world clock, speakerphone and memo pad. The higher end features consist in Bluetooth, GPS (Cricket Navigation), wireless web browser and 2.5G speeds.
As for fun, you have a pretty basic music player, a 3.5 mm head set jack, two games and a 3 megapixels camera that has editing options. The picture quality is mediocre: the colors look relatively natural, but the images look blurry most of the time. Rio has a few applications preinstalled: Google Search, MyBackup and shortcuts to Facebook, Hotmail, weather and sport headlines.
This phone is actually pretty basic and we would not recommend it to you, if you prefer text messaging to voice calling.
