That’s an interesting idea—if Proton were to expand into a full mobile operating system, it could really shake things up, especially for users who prioritize privacy and independence from big tech ecosystems. The main challenge would likely be securing hardware partnerships and strong app support, since that’s where most alternative systems struggle to compete with Google and Apple.

That’s an interesting idea—if Proton ever moves into a full mobile OS, it could definitely shake things up, especially for users who care about privacy and independence from big tech ecosystems. The challenge would be getting hardware partners and app support, since that’s where most alternatives struggle against Google and Apple.
It reminds me how communities around different platforms grow when people start exploring alternatives—same way I came across https://clashofclanmod.com/
while looking into new setups and tools. If Proton plays it right, they could build a strong niche over time.

Cooperation with grapheneOS

That would be a great idea A privacy-focused Proton OS could really attract users tired of tracking on Android and iOS.

Starting with Linux-based systems and smaller brands sounds like a smart move.

People want more control and simplicity now — same reason platforms like Null’s Brawl (https://null-brawl.io/) are popular for a smoother experience.

That would be a game changer. I suggest to go into the LINUX space. We only have Ubuntu touch and Sailfish. I am buying a Jolla Phone in order to leave the Android cosmos. If you would create this, that would be awesome!

Proton’s mobile operating system (OS) focuses on privacy and secure performance, giving users control over their data without unnecessary tracking or bloatware. Just as a well-designed OS prioritises transparency and efficiency, understanding the David Lloyd membership cost helps you make an informed decision before joining a fitness club. Knowing exact membership tiers, pricing structures, and what each plan includes ensures you choose a plan that fits your health goals and budget. Clear pricing information removes guesswork, boosts confidence in your commitment, and lets you focus on your fitness journey with the same clarity and assurance that a trusted mobile OS brings to your digital experience. https://davidlloydmembershipprice.co.uk/david-lloyd-leeds-membership-prices/

We need to find a way to extend Proton's protection to the entire computing environment. For example, Proton Mail is secure on phones, but using an Android keyboard breaks the chain of end-to-end encryption protection...

We need this on a fairphone

If Proton did this, it would be pretty epic.

The need for privacy is now more than ever, especially when oversaturation of the market from tech giants is pushing out competitors.

Everyone should check out GrapheneOS. I'd rather see Proton spend resources on their own suite and leave the privacy hardened OS work to the Graphene team.

Dear Proton team, you have the vision and the talents, please give us back our freedom !

Now isn't the time. It will be an exorbitantly expensive undertaking. Wait a few more years and save up for it. We get one shot. So many have failed before.

We need something like this. There's billions of smartphones, to say that there's only a market for two OS'es is ridiculous, especially as governments are cracking more and more down on the monopolistic tendencies that have given them their edge over the smaller competition. Combine that with an every increasing desire for privacy, and the market begins to become more and more realistic.
A privacy focused mobile OS that's not just made by a small company or group (like most alternative OS'es at the moment) but by a bigger player like Proton, would also make it much more attractive for app developers to make compatible apps, as they know that it isn't just some little niche thing, it will have proper potential that can realistically be built upon.

Alternatively you can try releasing your own smarthphone with degoogled Android or a private Android fork like Graphene OS

I know this cannot be done soon or easily and many have failed trying this like Microsoft, Samsung, Palm, Ubuntu, Mozilla, etc. But I certainly support the idea and hope it can be achieved one day.

While this would be cool, it would probably consume a lot of their time and effort, and would mean that other projects get much less attention. I would be 100% down to see this though, if they can pull it off

It's something like Harmony‌‌OS.?

I was going to post the same.

My thought is build a secure de-googled android os (or a brand new one) with proton apps natively built in. This may require a few more mobile apps to be created. (Proton Web browser, Proton Messaging client with e2e encryption, etc.)

IMPOSSIBRUUUUUUUUUU - YES please!

It would be nice for there to be more Mobile OS developers, but I don't think Proton should be one of them. They should stick to one area (which right now is email/drive-related stuff) and excel at that.
