Casio Exilim C721 Review

Verizon Wireless Casio Exilim 7.5

Posted: , by



The call quality of the Casio Exilim C721 was equivalent to the Boulder.  Voices in the earpiece sounded clear, but a bit hollow, and there was some distortion if the volume was turned up past level 4.  People that we called on a landline also said our voice sounded hollow and lacked depth.  This is most likely caused by the thin plastic membrane that protects the speaker and microphone from water.  The reception was a bit disappointing.  Even though the phone was used in high-coverage areas, there were times when the signal bars would drop and nothing would be shown for EV and 1x, even though our other Verizon test phones showed 2-3 bars in the same location.  We could still place and receive calls, but it is cause for concern for people who travel or live in areas with spotty coverage.

The 920mAh battery was able to provide up to 4 hours of continuous talk time on a full charge, which is slightly better than the 3.8 hour rating.


Even though the Casio Exilim C721 is a nice device overall, we have mixed feelings about it.  The camera’s image quality is better than most phones, such as the Chocolate 3, Alias 2 and FlipShot, but still doesn’t produce as good of an image as the enV Touch.  This is a bit of a disappointment since the Exilim has a 5MP camera, and the enV Touch is 3.2MP.  The reception was also under par when compared to most other Verizon phones, but call quality was average.  At this point, we would only recommend the Casio Exilim C721 to people who need a 5MP cameraphone with 3x optical zoom and absolutely require it to withstand water, sand, and being dropped, such as people on a construction site or hard work environment.  But if you want a device that will take better looking images (in our opinion), has more overall features, and don’t need the Military specs, the enV Touch is a better choice.

I don't get why the devcie only allows for 500 contacts yet 999 speed dials... not everyone sets a speed dial for 2 numbers per contact..... i would hope that future software updates allow more.

I am on my third sample of this phone and about to return it. I bought it because I thought the camera would be very good but I am extremely disappointed with it. 1. The 1st sample had defective audio on the phone receiver - very weak and distorted. Also the included software for downloading images from internal memory wouldn't install on a garden variety XP machine and Casio support was unhelpful. Finally, the auto flash didn't work correctly - the flash LED's stay lit between shots in medium to low light rather than flashing at the instant a photo is taken unless the flash is turned off entirely, as described in the review but not like any other auto flash I've used and saps battery very quickly. 2. 2nd sample had acceptable audio but a defective usb connection (actually an internal usb modem). Same flash problem. 3. 3rd sample had same flash problem, but audio and usb worked acceptably. 4. Picture quality on all 3 units not as good overall as my 1.3 MP LG phone, although it does have more resolution and somewhat better quality in bright light. There is no way to access photos in the internal memory except by use of the included Digital Photo Album software which didn't work since I couldn't install it. In any case, it is apparently not possible to access it by directly by Windows Explorer, Photoshop, or any other common photo software as is possible with most digital cameras. I didn't try its optional SD card which might be accessible without use of the DPA software. Just not ready for prime time in my estimation.
