![](https://cdn.nothing.community/2025-07-01/1751373606-22676-bannerlarge.png "banner") **The Glyph Matrix SDK is here!** And as you may have heard during our launch, we are once again publishing a Developer Kit to help our community build their own functions for Phone (3)'s new interface. We're grateful to @"Fr4nKB"#45598 @"RapidZapper"#3132 @"SebiAi"#28468 @"AndreaFanelli"#21677 and @"Rahul"#16057 for building the very first community Glyph Toys using an early version of the SDK. Their inputs helped us to refine our documentation and identify how to make building for Phone (3) as easy as possible. **Leveller** and **Magic 8 Ball** are great examples of what can be achieved - simple toys and tools that are utilised without turning on Phone (3)'s main display. **Head on over to [GitHub](https://github.com/Nothing-Developer-Programme/GlyphMatrix-Developer-Kit "GitHub - Glyph Developer Kit")** where you’ll find the repository and support documentation to get started right away (no API keys required this time!) *Looking for help testing your creation?* Share a post here on **[nothing.community](https://nothing.community/)** to showcase your work using the #co-creation tag, we'd love to see what you're working on. As always, we encourage collaboration between our members - let's create some awesome stuff together! 💡 ##### [Start Building](https://github.com/Nothing-Developer-Programme/GlyphMatrix-Developer-Kit "GitHub")

Vishwam Sorry, I think we’re not understanding each other, but I’m going to ask you some questions and then I’ll be able to answer you better.

Is your app made in Flutter or Kotlin?

What do you want to add? New features with the new API, or upgrade your old API to the new one.

Vishwam

Joseph_Developer My app is made in Kotlin and add new features with the new api for my existing app. First of all is this possible? Because right now my app is compatible with phone 1, phone 2, 2a series and 3a series so want to add phone 3 as well. So is it possible without disturbing existing features?

Joseph_Developer

Vishwam Interesting, in that case if you updated the API you would affect all the other devices, because as phone 3 only has a matrix Glyph and the others have normal Glyph this would be chaos.

What you can do is add the new API separately without affecting or touching the old API, so you have the functions of the other phones and the new phone separate.

Vishwam

Joseph_Developer Ok that way I can add all the device right without affecting other devices? Like 2 apis in a manifest files and 2 API files in libs folder? That would workout right? So for that I have to first apply for the new API right?

Joseph_Developer

Vishwam Yes it would work, but to keep your code and architecture clean I recommend that they be in 2 separate folders, one for the new one and one for the old one.

Vishwam

Joseph_Developer Ok thank you so much. Applying for the API for this glyph matrix and thinking about the features to add. Because the features I have for other phones can’t be added in this so need new bunch of features for this

Joseph_Developer

Vishwam Ok, I’m glad, I wish you success in your duties, see you!

Vishwam

Joseph_Developer Thank you so much. One last doubt, I was going through their .aar file and documentation. So in that file they added 23111 which is for 3a if I am not wrong and GlyphManager and GlyphMatrixManager as well. Then also will I need separate API for matrix? And shall I keep the old ketchum file in that?

Joseph_Developer

Vishwam Yes, keep it, but remember to keep everything clean and organized so that dependencies don’t conflict.

Vishwam

Joseph_Developer Thank you but I think you missed my second doubt of having separate API for matrix. The one they gave won’t work right and I will need separate for this? I mean keep both API

Joseph_Developer

Vishwam mmmm… I think so, you should maintain the APIs, right now I don’t have the API, I’ll have to test it.

Vishwam

Joseph_Developer Hey, thank you so much. Then I think before applying for another API I have to add features now and release this in closed beta and ask some phone 3 users to test it. I think that’s the best option

Joseph_Developer

Vishwam If you want, I can help you test it, since I’m going to buy the Nothing Phone 3, I just have to wait for it to arrive in my region of North America.

Vishwam

Joseph_Developer Thank you so much. Can you DM me so we can start. I am going to start making it soon and we don’t have to find or search for both

PAWL2a

how can someone learn to develop apps and anything like this. I’d like to give it a go, but i have ZERO knowledge.

Joseph_Developer

PAWL2a Hey, you can read the official documentation of the technologies, so you can learn

But it requires too much time dedication

Rob ⚡️ this is great but I imagine we need an actual device to test and build these? In the launch video there was a Matrix Simulator - will this be made available as it would be a great way to validate and test work without a phone.

PS: While it’s great work by all involved - feel like need to really polish up the SDK and tooling for developers to get the maximum traction on this.

So_rohantic

Rob ⚡️ a level tool and a compass WHILE also flaunting the design of the phone on site? As an architect I can tell thats so good XD

Joseph_Developer

Vishwam Ok! And how do you do that?
