The UMI Zero is the world's thinnest dual-SIM
phone, slimmer even than the iPhone 6
One issue for some users will be the lack of a
notifi cation LED when you receive new texts and
emails, although since our review a fi rmware update
has corrected this issue (see Software).Screen
For the display UMI has taken one of Samsung's
Super AMOLED panels. Super AMOLED is just like
standard AMOLED, but thinner and more energy-
e cient. AMOLED doesn't require a backlight
and produces very good contrast, but can display
oversaturated colours – fortunately, though, we quite
like this vibrance.
The display is 5in with a full-HD resolution of
1920x1080 pixels, equating to a very high pixel
density of 441ppi. Text is sharp, images are clear and
video looks great.Hardware and performance
UMI's Zero is an octa-core smartphone, running
the 2GHz MediaTek MTK6592 Turbo processor
with ARM Mali-450MP4 graphics and 2GB of RAM.
In comparison to Samsung's Exynos 5410, which
combines four ARM Cortex A-15s and four A7s
and can only ever run four of its eight cores at once,
this MediaTek chip has eight Cortex A8s that can
all run simultaneously.
