Nexus 4 is my favorite. I wanted to buy it at first, but I won't buy one thing. Its back cover is glass, which will break when it falls, so I can't buy it.
Compared with MX2, M2 has the following points:
MX2 works more carefully.
MX2 is 2G RAM, which is faster.
MX2 has a more beautiful appearance, narrow border, full fit and screen.
In terms of photography effect, MX2 is better than M2 on the rear camera; On the front camera, M2 is stronger than MX2, the former is 2 million, and the latter is 30. See if you have a selfie control.
If the battery capacity is 2000 mA, it is detachable, Meizu 1800 mA, and it is not detachable. Saving electricity is almost the same, depending on how you use it.
CPU, Mi 2 is from Qualcomm, but this is unstable,1.5g; ; Meizu 2 uses Samsung's MX5S, 1.6G, which is optimized and customized for MX2 and stable.
I recommend you to buy Meizu MX2, which looks really beautiful, does not play futures, and has a good reputation. In addition, I like the way it unlocks and closes the screen best. The screen locking and unlocking of MX2 can be completed through the virtual HOME button, which liberates the power button of the entity and prolongs the life indefinitely.
Of course, the shortcomings of MX2 cannot be ignored:
The front camera is only 300 thousand
The back cover is made of smooth plastic, which is not as good as one X.
Both batteries are not detachable.
All things considered, I recommend you to choose MX2!
I hope I can help you!
