This is the first ROM that I have seen that when I look at it I think "This is a custom ROM". Most of the others seem to focus on just adding lots of settings. I am pleased that there is at least one ROM that is customising the GUI.
Unfortunately, it is unusable for me
On first boot it is all in Chinese!
What do each of the buttons say?
I first pressed the green button which took me to what might be a login screen, all in Chinese too.
I then managed to go back and press the white text at the bottom right. This might a "Skip" link because it took me to the homescreen where it was in English.
However, lots of it is still in Chinese.
e.g. there seems to be a Chinese Market as well as Play.
"Ovoice" (voice control?) has all the descriptions in Chinese.
Some of the themes have English names but a lot still have Chinese characters.
There is a "ColorOS" app that I am not sure what it does because it is all in Chinese.
I'm not sure now how to connect to my Google account.
I flashed the miui gapps that were mentioned in one of the other earlier posts but it is missing several Google apps.
I haven't had it long enough to see if the lack of KitKat (and thus lack of deep sleep) impacts the battery.
And lastly I can't get network data.
All in all, I was very impressed but disappointed that I couldn't use it day to day for the reasons above.
