[FYT Android Head Units] eduarcor75:
Currently I am trying to make my recently bought unit Junsun V3 Plus UIS7870 2K 9.5" to work properly. You can follow the process here.

This thread is just related with themes launchers, in order to be able to understand how themes launchers work, and what can be done in our units related to them.

One of my biggest concerns about the Android Head Units is the UI (or Theme launcher, I guess). The current theme launcher in my device is not doing what it promised in the images, which is having a widget in the home screen (kind of like picture in picture?) so the Carlink application can be opened there in the home screen so you have your Carplay or Android Auto working in the main screen, but still controlling the rest of the unit, like radio, etc...

It comes with the widget pointing to the app google maps. you can change to others, but the list of apps available is not including Carlink. Important question:

0) Is it possible to put Carlink in that list in some kind of configuration file, or something?

For more context, as I comment in my mentioned main thread, my girlfriend's unit configuration is one of my favorites because of the layout (not talking about visually wise, which I think is more than correct) is this one:

This one comes with the widget pointing to google maps, but then you can add Carlink (or is call TLink here, I think), and it works like a charm.

The unit is a Junsun X7 4G. It does not look to be a FYT. There are other brands than Junsun comercializing an exactly the same product, like AWESAFE. So I guess is another branding standard stock unit, with no customization at all.

In this unit, I think there is kind of an store for themes launchers, in which you could buy them... not sure how it works. I never tried.

Just searching in Aliexpress, I just found a unit like FYT which is using the same as my girlfriend's unit theme launcher but in a regular FTY???:

So, based on all that I said before, I have some questions regarding themes launchers, etc. I will number them to be able to reply easily to anyone who could help me with my doubts:

1) Is possible to create themes launchers for our FYT units? Is there any framework available to use?

2) I see Mario Dantas have a lot of themes launchers to download (and probably there are other resources), but I guess is just for UIS7862. Is there any possibility to uses UIS7862 themes launchers in UIS7870? Can you link some other resources to download themes?

3) Even if a theme launcher is for UIS78620, could be ported to UIS7870?

4) It looks like a theme launcher could be very heavy embedded on a firmware, and It looks like some themes launchers can be installed in different firmwares, but I don't understand the dependencies between the theme launcher and firmware itself. Can anyone explain the boundaries of them, and how one needs the other, and why some can be installed in different firmwares and why some can't?

5) Any resource to download this exact theme launcher of Junsun X7?

6) Is Vincent Vega firmware (I Just love the theme launcher, which seems to be like/similar to Teyes?) be able to be used in FYT UIS7870 and not just in Mekede and Teyes? If not, can the theme launcher be extracted to use in generic firmwares?

Probably are pretty lame questions, and I apologize in advance if they are trivial.

Hope everyone can help me with the questions, and let me thank you for your patience and help in advance.
