Review: Samsung Impression
Screen
The Impression has an OLED screen with 240 x 400 pixels. This should be enough to get your juices flowing, but quite honestly, I didn't care for the display at all. It is suitably bright and colorful, no doubt. But the (what I thought was) low resolution for the size of the screen led to it constantly looking out-of-focus. (Yes, I removed the sticker protecting the display). Text, icons and such all has a slight haze to it. There's no other way to describe it. Everything was perfectly visible in bright sunlight, though.
Signal
The Impression did quite a good job at connecting to AT&T's network. Over the Easter holiday weekend, I took it to the local vault (ShopRite) repeatedly (because I am absent-minded and needed to make multiple trips), and it held onto a signal in there, and was able to make and receive calls with no problem. Other areas in Northern New Jersey where I brought the Impression didn't appear to tax it, and it had at least two bars of signal strength in most locations. Compared side-by-side to other AT&T phones, it matched them nearly identically in ability to remain connected to the network.
Sound
The Impression will ring loudly enough so that you're not going to miss calls in most instances. It isn't ear-drum-piercingly loud, but it is loud enough. The vibration alert can be set to varying different patterns, and you can have the phone vibrate before the audible ringer starts. The vibrate is also nice and strong. I didn't miss any calls through lack of hearing the Impression or feeling it. Call quality wasn't bad. Voices in the earpiece were clear enough, though there was a hint of hiss. I would have preferred it if I could make the earpiece volume louder. I had trouble hearing several callers whilst walking around the local mall.
Battery
We've had the Impression less than a week, so we don't have a definitive report for this section. In our time with the phone, it performed adequately in the battery life department. I killed a full charge between 7PM on Friday and about 11PM on Saturday. That was with heavy voice and Internet use. I charged it overnight Saturday into Sunday, and it still has half a charge on Monday, but I used it less on Sunday. We'll add more here as we test the phone further.
