ZenFone 4 is a very good phone and a welcome return to the British market

camera employs 3-axis electronic image stabilization
aberrations aside you can get seriously detailed night photos
tend to appear a bit weak or washed-out with less than perfect lighting
floating bar more distracting than anything else
daylight shots lacked detail and some also had a bit of purple fringing
we rarely saw apps getting closed
the volume buttons to be placed a little too high
as there is no way to tweak the output
the display lacks the wow factor of an 18:9 aspect ration
sometimes not reliable
over-sharpening and resulting artifacts marring the photo
real-world speeds are much lower
of over-processing with a bizarre ghost-like effect
No color shift was detected
frequency is too low
users with sensitive eyes may experience strain or headaches
sharpness drops considerably on the left side of the picture
display panels
drives or memory sticks with similar specifications
like Asus is some phone-making newbie
Slow response times can lead to afterimages and can cause moving objects to
the phone will fall out and land on the ground
does occasionally struggle to lock on at this kind of range
ZenFone 4 Pro does not support HD Voice
smartphones will blurry the sides of a face as they have trouble determining the foreground from the background
Glass is slippery and fragile
ASUS is only using one speaker here
this 14 second movie is 75Mb in size
resulting image does suffer from a lot of barrel distortion
Battery life is very sensitive to changes in screen brightness
it does not support wireless charging
but not good enough to actually want to use for extended periods
images losing a lot of detail over the main one
too expensive
Auto white balance and exposure are a bit hit and miss
have fast charging
this setting cannot be enforced by the benchmark app
device may be too hot or have other apps running in the background
