Hello all!

Due to the recent statements by Google (as well as their track record the last few years) I've decided I do not want to use Android as a phone operating system anymore. But Apple is just as bad, if not worse. So I've decided to build my own custom device.

I am working on building a phone using a single board computer, right now I'm using the raspberry pi 5. This is still a proof of concept, but I want to share my ideas with others, so like minded individuals can start messing around with this idea in their own homes to further this goal.

You can view more images of the device here, as well as the step by step instructions here (these are still very rough and incomplete) https://github.com/muhammadmanwar/cheaphone OR https://codeberg.org/muhammadmanwar/cheaphone

Right now it just runs raspberry pi OS, with a different desktop look and feel. Everything that normally works in a pi 5 works on this device, additionally I am experimenting with a Mobile Broadband modem, to allow the device to text and call, as well as access internet, like a normal phone off wifi

The total cost is around 200 dollars, not including the 3d printer to make the custom case.

This project is barely off the ground, and I've got a lot to learn before I can stop relying strictly on the raspberry pi 5, my end goal is to custom design SBCs, and release those designs for free alongside the plans for the device, so that interested parties can select their own System on a Chip to use for the device. I need to get into designing boards, I'm interested in trying Stephen Hawes' Lumen PnP (https://www.youtube.com/watch?v=JlkTcxh-9gA) for that phase.

But that's for the future, for now, I'm hoping to get more people interested in the prototype so that I'm not the only one noodling around on this idea. I'd love some feedback, and if anyone was willing to put one together for testing, I would appreciate it greatly!

This is a sexy device. But can I ask you to make a repo on codeberg ? Github has been taking down repos that might be a threat to Big-Tech monopoly

[–] digitalRights4All@lemmy.zip 43 points 1 month ago (1 children)

Thanks for the suggestion, I mirrored the repo here: https://codeberg.org/muhammadmanwar/cheaphone

I may end up switching entirely to code berg, but I'll see how bothersome it is to push changes to both before I fully migrate. Thanks again!

[–] Ghoelian@piefed.social 15 points 1 month ago

I'm not sure if you can do it the other way around, but you can set up a push mirror on codeberg so you only have to push to one forge.

What I wouldn't give (or pay) for a 1. sleek, modern smartphone 2. running a pure Linux distro 3. that's feature complete enough to daily drive

All of the current options available fall down in one of the three areas. Usually 2. and 3... mostly 3.

[–] leavemealone@sh.itjust.works 24 points 4 weeks ago (4 children)

Considering their recent hardware reveals, I want a valve steamphone with a fully open system and modularity a la fair phone (or like their new VR headset) One model every 4/5 years would be perfectly ok for me.

[–] kuhli@lemmy.dbzer0.com 11 points 4 weeks ago (1 children)

A valve / framework / fairphone teamup would be a dream. It'll never happen but I'd pay unreasonable amounts of money to see it

So what features do you really, really need?

[–] Routhinator@startrek.website 4 points 4 weeks ago (2 children)

Working hardware drivers. Stable phone and SMs applications.

Have yet to see either on any Linux Distro for Fairphone

Just reading the reviews and it sounds like it's got problems. GPS doesn't work, mobile data is sketchy. That's what I'm talking about. I'm fine to tinker and massage most of my devices into a working state, but not my phone. I can't be messing around with terminal commands trying to get my gps working when I'm out on a trail for example. Can you imagine if there were an emergency and I first had to try and figure out why telephony was suddenly down before I could call emergency services? My phone is the 1 device that HAS to work flawlessly every time.

[–] tomenzgg@midwest.social 3 points 4 weeks ago* (last edited 4 weeks ago) (2 children)

Which reviews had you read? Earlier reviews of the previous model aren't going to be as accurate as a lot of updates have led to improvements. You're not wrong that things aren't fully out of the woods (as is inevitably the nature of things, at this point in time) but most people who drive it daily have said that things just generally work, usually, these days. Their Matrix/Telegram channel may offer a more accurate depiction of the current state of things.

Now, Android/iOS level performance may be what's necessary to make the cut for you (that sounds sarcastic, for some reason, but I genuinely mean that as neutrally as possible) but I figured I'd mention since people will often mention the Liberux NEXX (a device which doesn't even exist, yet) without even mentioning this one and it's by far closer to an actual possibility of being daily driven out of everything else out there.

EDIT: for example, here's a review from a few months ago: https://clehaxze.tw/gemlog/2025/07-20-flx1-actually-usable-linux-phone.gmi. Again, I don't want to make it sound like bugs don't crop up occasionally (I don't we can expect otherwise this early in the game) but I do think this one's potentially actually feasible at being a daily driver far closer to what you're looking for comparatively to anything else out there, at the moment.

I don't care about this at all. This is a niche interest.

I just want a phone that isn't backed by assholes that want to sell my data.

[–] Valmond@lemmy.world 4 points 4 weeks ago (2 children)

Phones nowadays are so powerful I'd switch out my home PC if I could.

[–] Scoopta@programming.dev 3 points 4 weeks ago (1 children)

Powerful yes, powerful enough to replace a PC, I suppose only if you don't do that much heavy compute

[–] Valmond@lemmy.world 3 points 4 weeks ago (9 children)

My phone has 8 cores and 16+16 GB RAM.

It'll be okay for me.

Lika a Nokia N900 with a modern prozessor, camera, some GBs of RAM and a 5G modem. And of course Open Source drivers for the Hardware. This would be my dream phone (As the N900 was, back, when its Hardware was recent)

Wow! That does seem really similar to what I'm doing. And they seem further along than I am. I'll have to look into this project some more. Thank you!

This is a very helpful suggestion, thank you! I have been having some issues figuring out spacing, the battery sticks out like a sore thumb right now, so if this can save me some space I may end up moving in this direction for further prototyping. Thanks!

[–] rontosaurus@lemmy.world 10 points 1 month ago

Happy to see this out there, love the idea. Watching the repo may mess around with this at some point when I have more time.

This is a really cool idea. Any work in the direction of more linux phone technology is always good. There are some linux phones out there already, and these devices have had some problems which is why there hasn't been more adoption. If there is a way to do this with RISC and have decent battery life, that would be really exciting. Have you tried installing Phosh on it?

The newest, and most exciting, option right now is flx1s (https://furilabs.com/flx1s-update-2/).

One of the biggest problems is that, to my knowledge, there is no standard linux mobile App standard or, if there is, it's not often used. There is a group working on this issue right now (https://www.fierce-network.com/wireless/mobile-linux-standards-group-formed).

For example, if I am using mobian or something similar and download thunar using sudo apt install thunar, then if I run thunar, it will run, but certain menus won't display easily. In phosh, any sub-menu boxes will also pop up as a smaller pop-up box and to close it, you have to scroll through Apps to find the pop-up box and then close it. Generally I may be able to see the file structure on the left in Thunar but have a hard time seeing what's on the right.

There are also things that can happen in which default panels (like the side panel) take up so much room that you can't see what's going on. For instance, if you try running gimp in phosh, you can barely see the image panel by default.

There are some Apps designated as mobile-friendly but even these sometimes don't display correctly. Perhaps there should be a way to make it harder for Apps to be installed that don't meet mobile standards and have weird menu glitches, such as making it harder to download Apps from repositories that are not mobile.

I'd really like to be able to run something like "flatpak-mobile install librewolf" and just get something that at least had a file with it to tell phosh how to display menus in the best way, if not a slightly altered librewolf.

Many people who used phosh would say "well just use waydroid" but the problem is that with play integrity api, many of those Apps won't work.

In order for banking Apps and other Apps to run on linux and people to develop software, there really needs to be more adoption of mobile linux.

And yes, battery life was atrociously bad and completely unusable on the linux mobile devices I tested, which were a few years ago. It also got way too hot when just not doing anything, which was terrible. (In other words, if I took the device with me to Starbucks and got a coffee, it might get way too hot in my pocket; if I took it out and used the Internet for 20 minutes, the battery could die, and even if it didn't, if I were waiting for a call during that time there was a good chance I wouldn't get it. After getting back home, it would be totally dead and need a full recharge.)

Right now also, the main competitor to linux phones is Graphene OS with FOSS Apps and Graphene OS has better security features if someone is worried about their phone being stolen or seized. Data security is important to me and Graphene OS has a rate-limiting throttle to the password entry that even cellebrite can't easily bypass and a function to auto-reboot. If the political situation in my country deteriorated even more, and arbitrary arrests started to happen more often, I would much rather be arrested with a Graphene phone than a typical linux mobile phone. Mobile linux for certain distros such as Mobian still offers robust encryption in before first unlock (bfu) if the password can withstand brute force attempts, but since there's no hardware rate-limiter, the password has to be much more complex. Also, most people who use their phone frequently are not in BFU mode.

Graphene OS also requires a Pixel which does not have hardware switches and so a person must trust that there's no exploit allowing certain components to be turned on or off which can be concerning when there is no way to definitively measure what the cellular modem is transmitting. Call me paranoid, but given what I know about how easy it is for someone smart to exploit computers, I actually don't want a cell phone microphone to have power when I am talking about sensitive things or inputting passwords into computer systems and I do not want a camera that is built into the lcd part of the glass screen and can't be easily covered because of the need to swipe up nor turned off without a switch, even if the cell phone has an incredible operating system that is very secure. Graphene, unlike most mobile linux distributions, is mostly very usable with no battery life issues, no weird display problems where Apps don't display correctly and menus don't work correctly, and no random reliability problems, mostly. I understand not wanting to rely on anything involving Android, however, given Google's recent aggressive anti-privacy stances.

I'm excited about FuriPhone (https://furilabs.com/) and Purism's Librem 5v2.

The thing that I believe would help Mobile Linux most right now is people having conferences and getting to know each other and discussing standards, specifically on user experience, linux mobile app standards, battery life, and reliability.

There are so many smart people in mobile linux and eventually it will get great but right now there are major problems with the user experience because of how Apps are displayed and battery life as well as things like reliability.

So any way to gather people to discuss the mobile linux user experience and to come up with standards to reduce these issues would help, or even to help list all the different problems so that they can just be enumerated and acknowledged and worked on would help.

Another way that would help is to have a mobile linux security group or conference to discuss things like standards for making mobile linux more secure from brute-force attacks if stolen or seized after being unlocked.

This seems like a very ambitious project and a great learning experience for someone working on their own. For a similarly ambitious project, check out the Liberux NEXX. The project didn't reach its crowdfunding goal, but they did make some progress before rolling up the rugs.

I don't know if they're looking for contributors or if you're in a place to contribute, but most of the project is open source. You could probably get in touch with them and ask for any advice, successes and failures, and even if they have parts (such as their dev-board) that they can give you access to.

[–] just_another_person@lemmy.world 6 points 1 month ago

Not trying to dump on your efforts or anything here, but you'd be better off first defining a scope of what you're trying to do, and then work off an existing hardware or software platform.

You can get phone dev kits for cheaper than $200 if you just want to build something that works without Android, but if you intend to take that further and design some of the software experience, you'd be better off just working or contributing to something that already exists.

A single person can't even begin to touch on the fundamentals of what it takes to run a phone experience in that that we currently understand and use them. Touch UX, software<>hardware integration, peripherals like cameras...it's A LOT. Doing it well as a single developer is just not going to happen.

If your goal is simply to not have to buy another shit Google-infested phone, you can get a cheap that runs other things right now.

[–] buddascrayon@lemmy.world 5 points 4 weeks ago (6 children)

If you're really going to do this you need a RISC-V processor SOC. If you look around online there's a few places where you can obtain these.

When planning to go into mass production?

[–] rarsamx@lemmy.ca 14 points 4 weeks ago* (last edited 4 weeks ago) (1 children)

Why does it need to go on mass production? OP explained they want to get to a point where they share their design.

I keep repeating the same about Linux and other free software projects. The main goal is freedom, not market share.

OPs project seems to follow the same goals. And I find it awesome.

[–] Bazell@lemmy.zip 4 points 4 weeks ago

I meant the ability to order such a device. I just structured my opinion wrong. Because of sharing the device blueprints and software doesn't mean that anyone will be able to create it by himself.

[–] ravachol@lemmy.world 3 points 1 month ago (1 children)

I'm interested in this. Especially at that price point. I didn't see any photos of device though.

[–] digitalRights4All@lemmy.zip 2 points 4 weeks ago

I'm not sure how to add more images to the post, sorry. But I uploaded images to a repo, in the pictures directory. There are also step by step instructions to make one yourself! https://github.com/muhammadmanwar/cheaphone OR https://codeberg.org/muhammadmanwar/cheaphone
