Why is there no ART mode in the system after Sony Z1 liter 4 4?

Sony has blocked ART mode for several reasons.

1. In ART mode, the space occupied by the program will increase sharply after installation.

2. At present, the Android application has not been optimized for the ART virtual machine, and the compatibility is not good.

3. The power consumption speed will be faster in ART mode.

I guess the Sony Z1 doesn't use the ART mode.

It's true that there is no such thing anymore, and the memory card cannot be read.

Downstairs is right, if you're not a third party, or if you're not a development version, then you can't use this feature.

It's an environment of pure art.

There will be after obtaining administrator privileges.

1 It's not that there is nothing, it's that you don't open it.

Re-upgraded, the upgrade was unsuccessful.

You may not be able to brush the official package.,But you can brush third-party packages.,For example, MIUI and Le Frog and other ROMs,You can brush the system they adapt to.,Just replace the recovery on it.,The specific process is very long.,I won't play it.,There are all on the general flashing forum.,If you really can't do it, you'll go down by yourself to brush the elf.,The whole process is fool-like flashing.。

1,Mobile phone root,You can use z4root,kingroot,Or make Huihong use the flashing tool on the mobile phone (Master Zhuo,One-click to get root,) The cracking rate is very low,But v880 comes with a system of Bi Zheng Tong can be rooted,A60 is to use the flash elf,A66T is to use Master Zhuo,These are all rooted on the computer side;

2,Computer,It is to install the flashing tool,(Bell pepper,360 one-click root,One-click root,Mushroom cloud,Mung bean flashing tool, etc.,You can use xiazaiba's flashing tool,This is dedicated to nature with a dedicated one,For example, millet special hall book root flashing machine; )

3. After root, you must install superuser, which is used for permission management.

Press the steps inside. Closed luck Kai will be able to call the root.

No, due to the constraints of mobile phone hardware, such as CPU, many mobile phones can only support Android at present, and it is difficult to adapt.

How can there be that the system pushed Android half a year ago.
