Review: LG Optimus F7 for U.S. Cellular
The F7's display measures 4.7 inches across the diagonal and it has 1280 x 720 pixels. LG mostly uses in-plane switching LCD screens, and the F7 is no exception. The screen looks great. It is bright, sharp, and individual pixels are nearly impossible to see. Viewing angles are excellent, and there's no color change or brightness drop off when it is tilted. It is viewable outdoors, but you have to crank the brightness up a bit in order to see it.
U.S. Cellular does not provide its own network in the New York City area where we tested it. Instead, the F7 was roaming on Sprint's network during my tests. In that regard, it performed on par with other devices that use the Sprint network. It showed the same signal strength that a Sprint device would for a given location, such as my office, where it had two bars. The F7 was able to make calls on the first dial, and it did not drop or miss any calls due to signal problems. In even the weakest coverage areas, the F7 was able to connect calls with no problem. Data over Sprint's 3G network was slow, but it worked consistently. Unfortunately, we were not able to test the 4G LTE capability.
The F7 is an excellent voice phone. Calls were both crystal clear and loud as heck. The earpiece produced warm tones and voices had a natural sound to them. There was no interference or other noise coming through the phone. Outbound call quality was also quite good. Those with whom I spoke through the F7 said I sounded loud and clear. The earpiece speaker is quite loud when set all the way up. I was able to hear calls clearly over traffic when walking down the street and over the raucous laughter of a crowd enjoying happy hour. Calls sent to the speakerphone weren't quite as clean, and I heard an occasional scratch. But the volume of the speakerphone was good. It could easily be used in a noisy office or house for calls. Ringers and alert tones were also plenty loud. The vibrate alert was excellent.

The F7's 2,540mAh battery gave the phone more than enough juice to get through the day. The device had no trouble at all lasting from breakfast to bedtime, and often had plenty of power to spare. That's about all you can ask from a smartphone these days, especially one with a large HD screen. It is worth noting that we were not able to test the F7 under LTE coverage, though. You'll need to charge it each night, but otherwise shouldn't have to worry about it when out and about.
