Display

The Umi Affect is listed as coming with a 5.5-inch "LTPS two.5D Arc screen" with a resolution of 1920 x 1080. Umi hasn't specified the verbal type of technology used (LTPS, or low-temperature polycrystalline silicon, is a type of TFT design), but it's clearly an LTPS-TFT IPS-type LCD with a pixel density of 441 PPI.

On paper this is a really compelling display, because you don't oftentimes come across 1080p resolutions at this cost point. The resolution is certainly fantastic, providing precipitous imagery and text, and I was pleasantly surprised past the excellent viewing angles exhibited by this display. These ii aspects to displays are often compromised in upkeep devices, but non here.

The Umi Touch's display packs average brightness and blackness levels, which result in a contrast ratio just above 1000:one, which is what I'd expect from a upkeep handset. The 2015 Moto Yard's display can go a bit brighter than the Impact, but the thin glass panel and great viewing angles withal makes this device viewable outdoors.

I wasn't as impressed with the Umi Affect's color performance. For some reason, Umi has targeted the ancient NTSC colour standard hither, rather than sRGB, which is the merely color contour that Android supports. And you're not even getting the full NTSC color space, with Umi challenge 95% coverage here.

Across the board, the Umi Bear on's display is inaccurate even for budget handset standards. The brandish is far likewise cool, and poor accuracy makes some images look very unnatural when viewing them on this display. You do go decent saturation which can make images 'pop', but not in the same way every bit a Samsung Galaxy device: images are oversaturated and just don't look quite correct, especially when a scene is dominated by grays.

The Touch does come with a "MiraVision" display tuning engine, but literally no settings I adapted actually improved the color operation. Trying to brand the screen warmer and closer to the correct 6504K value significantly affected colors and fabricated the display wait absolutely terrible. It'due south clear that Umi needed to identify a much greater focus on color accurateness and they need to target sRGB over NTSC.

I also experienced some issues with the Umi Touch's touchscreen failing to answer fairly to taps, swipes and gestures. About of the fourth dimension the touchscreen is fine, merely on occasion it completely fails to register a tap, or responds very slowly to a gesture. This could exist a functioning issue (more on that later), though I suspect there are some underlying problems with the touchscreen as well.

With that said, Umi has been addressing some of these issues since I showtime received the unit of measurement more than a month ago, and the touchscreen performance has improved greatly. Withal, information technology'southward unfortunately however an outcome that affects the usability of this device.
