The codename is a single word unique to a particular device model. Phones can get released under more than one name (example: Xiaomi Mi 9 Lite on the global market, Xiaomi Mi CC9 in China), and so codenames exist to prevent confusion (for both the Mi 9 Lite and the CC9 the codename will be the same - pyxis - since they’re the same device)

This is a table with all the devices from the Note 13 series and their codenames (middle column)

From what I could gather there really are no official ROMs for any model from the series, but there are plenty of unofficial ones. Unofficial ROMs can be dangerous to run so you really don’t want to install one on your daily driver.

Your only option in that case imo is to buy a phone with better custom ROM support. Xiaomi phones have always been excellent for custom ROMs since they give you very good hardware for a very low price (if you buy them second hand that is).

The only drawback is that unlocking the bootloader (which is a necessary step on almost all phones in order to be able to install a custom ROM) on a Xiaomi device is very annoying and tedious, requiring you to go through Xiaomi’s janky servers, outdated tools, and the infamous 7-day (at least) waiting period.

As a point of reference, I currently run a Xiaomi Mi 10T Pro. I bought it used for ~500 PLN ($120 more or less). Compared to the Note 13 Pro 5G it’s certainly weaker. (which I assume is what you have since there doesn’t seem to be a non-Pro 5G model nevermind I’m blind and stupid, but I’ll leave the comparison as is)

Abridged specs for the Mi 10T Pro are as follows:

• 144 Hz IPS LCD screen
• Chunkier in all dimensions than the Note 13 Pro
• Heavier too
• No SD slot (same as Note 13 Pro)
• 128 or 256 GB of storage, depending on model
• No headphone jack
• Triple rear camera array (wide-angle, ultrawide, macro)
• Main camera is optically stabilised
• Main camera’s raw resolution is a little over 27 MP (the advertised 108 MP is achieved by proprietary Xiaomi software)
• 5000 mAh battery, 33W charge rate
• 563k AnTuTu benchmark score (good CPU)

And the Redmi Note 13 Pro 5G for comparison:

• 120 Hz AMOLED screen
• No SD slot
• 128 to 512 GB of storage, depending on model
• Headphone jack present
• Triple rear camera array (wide-angle, ultrawide, macro)
• Main camera is optically stabilised
• Main camera has a software-assisted resolution of 200 MP - I assume the raw resolution is 50 MP at most (which is extremely good)
• 5100 mAh battery, 67W charge rate
• 523k AnTuTu benchmark score (gsmarena doesn’t list the score for AnTuTu v8, which was used for the Mi 10T Pro - this phone was tested on v9, so the score comparison isn’t perfectly accurate)

So the Mi 10T Pro is visibly worse, but not by all that much (unless you love headphone jacks), and yet in part because it’s an older model (released 2020 as opposed to 2024), it’s supported officially by LineageOS, and that’s the OS I’m currently running on my own Mi 10T Pro.

With that in mind, installing a custom ROM is a very technical process, so it might seem really daunting at first (and that’s because it kinda is), but after your first flash things get way easier. I definitely do not regret switching to custom ROMs and if anything I kinda can’t live without one now, seeing all the bloat and adware on modern OSes.

Currently they’re not close at all to being daily drivers (can speak from experience as I’ve flashed Ubuntu Touch onto a phone a few days ago), but their development has sped up a lot lately, so here’s to hoping for the best!

A bit late to the party here, but today I flashed Ubuntu Touch onto a Xiaomi Poco X3, and it’s… well, it’s rough.

All the base functionality seems to be there, calls should work (not sure because I didn’t test them extensively), sms works, location/gps works, nfc is supported, camera is… passable, battery life is certainly, and noticeably worse but that’s a given - when on standby, the battery goes down roughly 8% every 5 hours, so approx. 27% per day on standby.

While I’m really glad to see how much Linux phone development sped up, they are still nowhere near daily driver status - even the phones built with Linux support in mind are not faring well from what I’ve seen. Even then, I’m keeping this Poco X3 because Android’s days seem to be numbered.

Wow, what a sight! Surprised there was a Lineage ROM for this. What model is this?

Sweet! I better get to work while it’s still possible.
