Comparing specs of upcoming Linux phones

– 3840 × 2160 – 16∶9 (Ratio: 1.778) - consumer media and display industries,
– 4096 × 2160 – 256∶135 (≈19∶10) - digital cinema production.

Yes, but back to main camera, here is link to, for example, ultra-sharp 4K (2880×2160@24fps) AR0521: CMOS Image Sensor, 5.1 MP, 1/2.5" supports 1440p30 mode for 16:9 video (HDR included) with recording resolutions of 2160p (24 fps) / 1440p (30 fps) / 1080p (60 fps / 30 fps) / 720p (120 fps / 60fps) / WVGA / VGA, so i think that 2880×2160p24 is max. that we can expect from any 4K wide angle camera within smartphone to be processed (having only 30fps option operational/available on Samsung 13 Mpx Standard or 5Mpx S5K3L6 Wide Angle lens variants):

My main point/guess here is that encoding maximum for S5K3L6XX (ISOCELL 3LXX, 13MP with 4208 x 3120 usable pixels) is 1080p@30fps and 720p@30fps, but without having 720p@60fps support at all?

P.S. @amosbatto, if Replicant have relevant 60fps and 120fps support sources, I apologize! Thanks anyway!

In case anyone is shopping for a Linux phone, I have created a table comparing the 12 models that can be bought with Linux preinstalled:

I didn’t bother to include phones like the Fairphone 2 and Nexus 5 in the table, because they require that the user install Linux, but the table would be much larger if it covered all the phones on which Ubuntu Touch, Sailfish OS and postmarketOS can be installed.

I also clarified the situation with RAM speeds on the PinePhone. The A64 supports a max of 3GB DDR3-1333 at 666.5MHz, but the max LPDDR3 clock is unspecified and the PinePhone distros are using RAM speeds between 552 and 624 MHz. In other words, the Librem 5 is using LPDDR4-3200, whereas the PinePhone is using between LPDDR3-1104 and LPDDR3-1248, so don’t just look at the 30% difference in CPU speeds to estimate the speed of the two phones.


I have to assume that Replicant has access to Samsung’s datasheet for the S5K3L6XX, since the data that Replicant posted about the S5K3L6XX is very specific, and they couldn’t have gotten that info through testing (since there is not yet support for the MIPI CSI-2 interface in the mainline i.MX 8M driver).


Good work on the spreadsheet. :boom:

Thank you for the great table!

I wish it had LibreOffice format and not proprietary Microsoft format.


The problem is that free accounts in don’t allow uploading .ods files (but do allow .xlsx files). However, I have uploaded the file to one of my VPS’s, so you can download it now in an OpenDocument format:

(Technically, XLXS is an open format if you don’t mind MS corrupting the standardization process and using binary blobs. :slight_smile: )


I noticed that too - but then if we want people to adopt Linux phones then we want to reach people for whom LibreOffice formats would not work out-of-the-box.

On that score, perhaps there should be an HTML version available on the web.

Yes, it has a documented standard.

I suspect what goes wrong though is that the standard is so complex that in many little corner cases the standard is open to interpretation and effectively in those scenarios Microsoft’s implementation defines the standard, not the standards document itself.


One of the noteworthy things that really stood out from the spreadsheet is the sheer number of Linux distributions using Phosh. Even if the Librem 5 crashes and burns, which I don’t believe it will do, Purism will have made a huge and lasting impact on the ecosystem and community with Phosh. Kudos!


…and Phoc and libhandy…


You are, of course, correct. Phosh is the “shiny thing”… and I was dazzled.

Librem 5 GPU can be clocked 800MHz at 0.9V and 1000MHz at 1.0V. We don’t have DVFS for GPU implemented yet, so right now it’s limited to 800MHz.


I’m betting that feedbackd also becomes a thing in other distros or hardware from other companies in the future too. Something as simple as a blinking indicator light can have a lot of appeal.

Maybe you could add manufactured units numbers to this table… Well… estimates…

UBports said in one of its monthly reports that there were 4000 to 4500 units shipped of the PinePhone CE: Ubports. In her CCC presentation last year, Nicole Faerber said that Purism’s goal was to produce 10k units of the Librem 5. We don’t have any other information about production numbers of the two phones.

Then I would say:
Estimated manufactured units:
Librem 5: tens (or hundreds? doesn’t seem so many)
Pinephone: at least 4000 (or thousands)

Any proper guess is better than nothing.

I can’t understand this secrecy. Maybe they need to hide some numbers of what they are going to produce so they could negociate better, but why do they need to hide the numbers of what they have produced so far??? That’s so lame…

Isn’t the manufactured units number going to be perpetually out of date?

Specs are fixed - until the next model comes out. This topic is attempting to compare specs.

Could well be around 10000 by now.
What we don’t know is, how many Purism will put on stock and whether they made some deals with companies who take hundreds or thousands.

I would like to see what have been build so far, not pre-orders/goals.

Yes, you are right. But I see no harm in adding built unit numbers to this fairly complete comparation. I think that every interested user would like to know them and they could very well learn them here alongside other info. The numbers can be updated from time to time… A timestamp can be specified.

If the numbers are lower than some customer thinks it ought to be (if, for instance, production is slow in the beginning and the gets faster over time, as has been stated) someone WILL start announcing that Purism won’t be able to meet their shipping deadline and go all over the internet telling people to cancel their order because they’ve only produced X phones when it should be Y phones, which would require Purism explaining their manufacturing process and going into a whole bunch of details they shouldn’t have to which will open the door for MORE speculation and the cycle would continue.

It ultimately boils down to impatience. The phones will come, and there’s no evidence to the contrary because a lack of evidence is not itself evidence. Sometimes, you’re just gonna have to wait.


There are now twelve phones in the comparison too. That’s a lot of work for someone chasing down sales numbers that companies don’t necessarily publish.
