bazza, 02 Mar 2015But the specs are worse than the z2 ?????????Of course look at the price wah u expect
OMG , this is the ultimate mid range mobile .
superb premium look , ,almost similar to Z3
1. 64bit processor
2. 13mp & 5mp
3. 2GB RAM
4. Waterproof that too without USB FLAPS
5. Stereo speakers
6. 2400mah with Sony's 2days battery life ( don't think about doubting Sony's claim , they already proved it with the 2days battery life of Z3 )
even if I had to choose between Z3 & M4 , I would choose M4 aqua because snapdragon 615 is more than sufficient for every day use, high use , and all that awesome specs I can get at half the price of Z3.
what more do you want??? this is the best . 2days battery life is the best ,even if I get 1.5day , Its awesome.
SONY YOU NAILED IT . 2015 is gonna be yours.
5 inch.i am going to buy it... When it might become cheaper...i love the phone design and shutter button.
Only cons is Sony should have added bravia engine or x reality.plus maybe triluminous display.
Hey..i wanna buy new phone is it good..i was thinking to get e7..but my frnd told me that m4 aqua is good..wht abt gaming experience video quality..nw am using xperia m..plz guide me is it gud to get this phone
So sad that this device comes without bravia and triluminious display
Someone please help, is it 5 in screen or 5.2 in. And is it 145mm tall or 140?
This is a great effort by sony.hope it had x reality or bravia engine.
It would have been a big hit if it had triluminous display..

kinny, 02 Mar 2015what this meaN sony bravia engine? Or xreality FOR WAHT USEWith the Mobile BRAVIA® Engine, the contrast in
images and video is enhanced by making the darkest
parts slightly darker, which results in a perceived higher
contrast that brings out details in the picture. This
contrast enhancement is adapted to each individual
image to avoid further reduction of brightness on
images that are already dark, and to strengthen the
contrast enhancement on vivid and bright images. As
seen in the illustration below, this will give your images
and videos more dynamics and better perceived details.

the Mobile BRAVIA® Engine.
Colour Management gives deep and vivid colours
Colour saturation is also increased for specified colour
ranges when you are running the Mobile BRAVIA®
Engine, which will make the colours deeper and more
vivid. In general, the human eye prefers deeper colours
on photo and video. This is especially true for natural
scenes. As you can see in the illustration below, the
enhancement level and the enhanced colour ranges are
calibrated to suit human eyes when running Mobile
BRAVIA® Engine. This makes sure that colours on
photo and video are represented in a way that is
pleasant for the eye.

the Mobile BRAVIA® Engine.
Noise reduction for clear video viewing
Another use case where Mobile BRAVIA® Engine
comes in useful is when you are streaming low-quality
video from online sources, as the compression
algorithms usually used by common web services such
as YouTube, often cause distortions and many
artefacts in the image. For videos stored locally on
your smartphone, there might also be a risk of noise
depending on the video quality of your clip. The noise
artefacts that most commonly occur when using such
compression algorithms are Block Noise , and Mosquito
Now by using Mobile BRAVIA® Engine, all of these
disturbances are greatly reduced as it reduces
temporal and spatial noise caused by these artefacts in
low-resolution video. Spatial noise reduction means
that image noise reduction is applied to each individual
frame, and temporal noise reduction means that noise
between frames is reduced. The Mobile BRAVIA®
Engine combines these two methods to get an
improved user experience when watching videos.

done by the Mobile BRAVIA® Engine.
Sharpness filter increases detail level
As a final step in the Mobile BRAVIA® Engine, a
sharpness filter is applied to increase the overall detail
level in the image. This is done by enhancing the
edges, as seen below, and the enhancement is
calibrated to increase contrast between different
image areas, but still avoid an increase of the amount
of noise present in the image.
Illustration showing the effect of the Mobile BRAVIA®
Engine sharpness filter.
As you can see, the effects of the Mobile BRAVIA®
Engine enhance the image viewing experience
drastically. And the best thing is that you basically only
have to pick up a fairly modern Sony Xperia™
smartphone to enjoy it, as this Sony imaging
technology is included in most Xperia™ smartphones.
