Hello, everyone.
Last time I tried to port KDEConnect to Ubuntu-touch, I did found some codes of mobile friendly qml app for linux phones. But due to I could not found how to build it, it failed.
But now I have found the build guide from its wiki
Seems it just need add a cmake flag and everything will go fine.

cmake -DSMSAPP_ENABLED=True .

Seems it is a good news.
However, I don't know how to type these into clickable. Obvisely we need more work than just simple type these word in.

@dobey I don't agree with " China has an exhaustive set of regulations for smart phone interfaces, that must be met to be sold on devices." China goverment didn't not has such law or regulations of that. Maybe you mean Huawei's regulations.Yes, Huawei don't allow we unlock our phone's bootloader and flash to Ubuntu-touch. Beside, Huawei has its own mobile system according to the news.
But, WeChat,Alipay,some school application,DingDing(a application used for discuss about work),all map apps and so much application only has IOS and Android version. Also all of them don't have a web version.(maybe maps application has one, but it didn't work very well)n They are so important for every day life that nowadays most Chinese people think if a mobile phone can not install thers apps, it is as same as a Nokia 3110. Just like a phone in your hand without Telegram, Twitter,line,facebook.
In my opinion,LACK OF IMPORTANT APPLICATION IS THE BIGGEST PROBLEM TO SPREAD UBUNTU-TOUCH IN CHINA, NOT THESE REGULATIONS.

In my opinion, for users who have never used the Ubuntu Touch system before. It is hard to know how to use Ubuntu Touch because all operation are hidden. And It would be great to set a ‘Simple to get started’ at the first time of system start. And add some guides in 'UBports' app for some addition guides.

These picture is the Meizu Flyme User help app.(It is Chinese because my main language is Chinese, I added some translation for it.)
I think Ubuntu touch should also have a app like this.

This picture shows a search input on the top.
The character “新手指引,老死机带你玩转Flyme” on the top means "A guide for these are new". Click it will show some tips of Flyme.
Blow it are some tips(also some ads, :<);
And then is Normal question(常见问题), click will show next picture
Some useful translation:
搜索问题=Search question
提交 Bug=log a bug
功能建议=feature request
全部专题=All topic(just a blog of flyme)
魅友知道=Meizu's fan Q&A(someone can ask a question, and other answer this question)

And this picture is the "Normal question"(常见问题), a Q&A by Meizu offical. It shows a list of what sort of question,such as use of communication apps (通讯), network(网络),setting(设置)
These really help when searching for a solution of a question. Rather than put all Q&A together.
some useful translation:
通讯=Communication apps
网络=Network
设置=Settings
桌面与主题=Desktop setting and themes
系统程序=Core apps
多媒体=Media
系统工具=as same as core apps, I don't know why meizu set two instead of one.
帐号与安全=Online account and security
手机管家=phone Guardian
相机与图库=camera and gallery
电量管理=buttery manager
实验室=some test feature in flyme

@CiberSheep
It seems is much harder than I think of the porting job on halium.

But for unlock bootloader, I think if a user want to flash ubuntu-touch into their phone, they should already know these risks.
Rather than let user searching for how to unlock it, we can give them a easy way.
And of crouse installer should warn them before do the install job.

As the title said. I think we should add a start animation for apps. For example the app icon push out from bottom side(Like what Android 5.0 did, maybe left is better for Ubuntu-touch as our lanuncher is there)
Animations can make the start process more smooth and let users feel the system more faster(For not feeling the waiting time)
