Review: Samsung M570 Restore
The Restore has a 2.4-inch display with 240 x 320 pixels. That makes it as average as a display can get in terms of both size and resolution for a non-touch device. You're going to notice pixelation of text, graphics and icons here and there, but it's nothing terrible or distracting. Colors look good, and I never had any trouble reading text on the display...unless I was outside. The sun obliterates the Restore's display. I even had trouble reading the screen in a bright room.
The Restore performed better than average when compared to other Sprint phones. It nearly always displayed a full signal and only rarely dipped down to one or two bars. I never had trouble making or receiving phone calls, and the Restore didn't drop any calls, either. In travels around the metro NYC area, the Restore held up quite well.
Unfortunately signal performance didn't equate to crystal clear phone calls. Many of the calls made with the Restore had a "digital" sound to them. There was mild hiss and noise audible every so often, and I had a nasty echo at one point that forced me to hang up and re-dial the call. Those with whom I spoke on the phone reported sound issues, as well. These problems became amplified with the speakerphone. I would not conduct a business meeting with the Restore, that's for sure. Too much noise, not enough volume. Earpiece volume was not quite good enough. The ringers and other alert tones were acceptable, though I'd prefer if they could be louder. Set to their highest levels, it would be possible to miss a call or a text message in a noisy environment.
The Restore's battery easily made it through three days. I was very pleased with the battery performance. My guess is if you really step up text messaging to hundreds sent per day (as opposed to the several dozen that I sent/received), you'd eat into the battery life some, mostly because the display will be on that much longer. Bluetooth use appeared to have no effect on battery life at all. You could easily make it through a weekend on a single charge.
