[Google Pixel 2 XL Questions & Answers] toknitup420:
Of course it will. It's the whole seemless update thing that they love. Remember pixel is not a true dev phone like the old nexus devices. They're now going for a more consumer friendly model. Seemless updates is just a great selling point. Most consumers have no idea what it means. But the word "seemless" sells itself.
[Google Pixel 2 XL Questions & Answers] cb474:
What are the phones that devs prefer these days?

Also, is everyone else (Samsung, etc.) going for the dual partition setup?

And why can't they just change the partitions on the phone? I guess I'm so used to partitioning my Linux systems any way I want and having a lot of options that it seems odd that the partitions must be left alone.
[Google Pixel 2 XL Questions & Answers] Treshy:
the best dev phone is still the google phone, the pixel.

eventually all android owns will shift to the dual partition model.

what's your problem with dual partitions exactly, because it offers lots and lots of benfits.
[Google Pixel 2 XL Questions & Answers] zelendel:
No its not. The dual partition setup makes developing for the device a nightmare. To the point that devs have started adding the dual partition setup to the list of things to avoid when getting a device. Add in the closed sourced system files Google uses on the pixels and you get a none dev friendly device.

No not all OEMs will shift to it. You can just look at how many device have it, even though it has been around for over a year. Just like adaptive storage.

To answer the question, many devs have moved over to OEM like one plus
[Google Pixel 2 XL Questions & Answers] BoboBrazil:
Hopefully it doesn't have it. If so I might stick with OnePlus(which imo has taken over the Nexus mantle for dev friendly affordable phones). I only used root for adblock and youtube background play, but without those a phone isn't a phone to me lol
[Google Pixel 2 XL Questions & Answers] cb474:
Yeah, I didn't realize this happened with the Pixel. Pretty disappointing. I does look like the four month old OnePlus 5 has a lot more development for it than the one year old Pixel phones. And it has official Lineage OS support. I'm still amazed that there is no official Lineage OS release for last years Pixel. What a sad change of fates for what was the former venerable Nexus line of phones. I wonder if the new Essential phone has a dual partition scheme. They claim they are going to be dev friendly, although they still haven't released their kernel source.

By the way, are there any other phones, other than the Pixels, that use dual partitions?

I still don't really understand why the paritition scheme can't just be rewritten by the devs for cutom ROMs. It's such a common place thing to do on desktops.
[Google Pixel 2 XL Questions & Answers] zelendel:
The essential phones were a bust. A sprint exclusive killed it. They inky sold like 5000 units total.

I have the one plus 3 right now and to be honest. I am not tempted to upgrade. It is still very powerful with a few years of development left.

The only ones that I know of for sure that use it are the pixel line and the new android one reboot. I can't say for sure on all the others but those are the only ones I know for sure.

To be honest I am not sure what the details are of the issue. None of my devices ever used it. So I only know what the devs talk about it in chats.
[Google Pixel 2 XL Questions & Answers] cb474:
Thanks for the thoughts.

It was actually reported a week or so ago that, at that point in time, Essential had only sold 5000 units through Sprint. No one knows what the sales have been directly from Essential. I suspect far more people bought directly from Essential (based on what I see people posting and that people who like phones like this tend to be T-Mobile customers). So maybe there's hope for Essential. Even though I have been disappointed by them in many ways and ended up passing on the phone, as much as I like the screen design. Or maybe the second Essential phone will do better and they'll become a company like OnePlus with some interest from devs.

Looking around, it also seems like there's a lot of development for the LG phones, I guess they allow unlocked bootloaders? It seems like every LG G* and V* phone has an official version of Lineage and a lot of ROMs in their XDA forums. I've never been an LG fan, but maybe they are a better way to go these days, if not OnePlus. I would have considered the OnePlus 5 but I don't really want a phone that big and I'm disappointed they dropped OIS for a dual camera gimmick. It seems like the 3 and 3T are the nicest of the OnePlus phones so far.
