[Moto Maxx Android Development] ChazzMatt:
Thanks for the mention. I was using this phone as daily driver from late 2014 to late 2017. Between me and my wife, I owned three Quarks one point. It was the BEST phone of 2014 (OLED display, Qi wireless charging, 3900 mAh battery, 3GB RAM, etc) and had great specs even into 2016. Only with 2017 Snapdragon 835 did I feel the need to change phones, and by that time stuff like IP68 and fingerprint sensors had come along as de facto features on premium phones.

Even after I switched to LG V30 in December 2017, my wife was still using her Moto Quark a few more weeks into 2018. So, I've been here through it all... from KitKat to Nougat. But I have no experience with Quark Oreo. I'll have to let others chime in on that. I will relate my experience with updating to newer OS ROMs on Quark the past few years...

I know I was always the laggard for latest custom ROM, as over the years I changed my mind and decided I needed stability (and my wife sure did).

In 2015, I QUICKLY jumped to CM 12.1 (Lollipop), but stayed on that for a year, well after Marshmallow ROMs were out. :rolleyes: But CM12.1 was ROCK stable.

In 2016, I then switched to RR Marshmallow (and loved it) about the time [MENTION=5747496]bhb27[/MENTION] was releasing his first RR Nougat ROM. ;) But I KNEW RR Marshmallow was very stable!

I finally went to RR Nougat many months later, sometime in 2017.

Yes, I KEPT UP with all the ROM threads -- and still do. I knew which were the best (from user feedback and dev responses), I participated, gave answers to help others. But I stayed behind the bleeding edge, because I rely on my phone in my job almost like a laptop.

- How stable/smooth are these ROMs? Good for daily driver phone yet, or should I hold off flashing for a few weeks/months?

Neither [MENTION=5747496]bhb27[/MENTION] nor [MENTION=6069596]calsurferpunk[/MENTION] would release these Oreo ROMs unless they felt they were inherently stable. My goodness, [MENTION=5747496]bhb27[/MENTION] been under enough pressure from everyone like little kids at Christmas to release Oreo! He could have just thrown something out there MONTHS ago -- and I'm sure he had tons of earlier test versions he could have simply labelled "alpha" and thrown to the wolves. So, knowing [MENTION=5747496]bhb27[/MENTION] and [MENTION=6069596]calsurferpunk[/MENTION] these cannot be bad ROMs. They both do quality work.

Will these be even better a month or two from now? :cool: Yes. Also,

[MENTION=5747496]bhb27[/MENTION] is one person, and he doesn't use GAPPS (or didn't) personally. Most other people do. [MENTION=6069596]calsurferpunk[/MENTION] will improve even more.

Different people use their phones in different ways. Even over in the LG V30 forum where I am now very active (I wrote the

LG V30/V30+/V30S bootloader unlock, TWRP, and root guide

) people will come in with very strange use scenarios that surprise me.

So, for the first month or two, [MENTION=5747496]bhb27[/MENTION] and [MENTION=6069596]calsurferpunk[/MENTION] will be fixing bugs other people find that they couldn't, just by themselves. And that's OK.

- Are there any issues with these ROMs that still have to be worked out? (Bluetooth, camera, calls, data connection, etc.)

In this thread -- unofficial LOS Oreo ROM -- [MENTION=6069596]calsurferpunk[/MENTION] just fixed a bluetooth issue. [MENTION=5747496]bhb27[/MENTION] is busy night and day working on stuff. So, if you are not completely comfortable don't feel compelled to jump in right now. Do feel compelled to donate them some money! ;)

I am actually praising [MENTION=5747496]bhb27[/MENTION] and used both his RR Marshmallow and RR Nougat ROMs with much satisfaction. I just didn't install immediately upon release. I let others report bugs and let him fix them. THEN, I installed... :) I also greatly respect [MENTION=6069596]calsurferpunk[/MENTION].

- Is VoLTE a thing? Not necessary for me, but don't know the ins and outs of VoLTE and how to use it...

No. On the Quarks (XT1225, XT1254, XT1250), VoLTE is only on Verizon network for XT1254/XT1250 on stock Verizon XT1254 firmware (with most "recent" being Marshmallow in December 2016) or the one ROM based on stock Verizon Marshmallow firmware (again, most "recent" is taken from December 2016 firmware). Even then, again that Verizon VoLTE ONLY works on Verizon network. It's a Verizon-only feature, which I do not understand. Motorola could have given ALL Quarks VoLTE for many, many carriers -- but chose not to do that.

We only have Nougat and Oreo ROMs (after Marshmallow) for Quark thanks to [MENTION=5747496]bhb27[/MENTION] kernel work -- but no Nougat or Oreo Quark ROMs have VoLTE. Do you want current security updates, custom features -- or VoLTE? Many choose custom ROMs like this, even on Verizon! The features and updates are just to good to pass up.

However, you bring up an interesting point...

END OF CDMA

Verizon is shutting off CDMA at end of 2019

. Verizon will become LTE-only network, which means you will need a phone with VoLTE on Verizon, by end of next year.

People NOT on Verizon don't care. But for people on Verizon using the XT1254/XT12150, you've got less than 1.5 years to get another phone. Or go back to stock Verizon Marshmallow for VoLTE?

I do not mean to hijack this ROM thread, but for people looking for another phone, the LG V30/V30+/V30S is fantastic. For Verizon users you don't even need a "Verizon" branded model, you can convert any North America model (like the

Sprint LS998 V30+, mint $320 -- with 128GB internal storage and 4GB RAM. I bought two of those.

) to use for Verizon. Many people have done that.

Bootloader unlock, TWRP and root and [URL="https://xdaforums.com/lg-v30/development"]

custom ROMs available

[/URL]. Just do NOT NOT buy T-mobile H932. All V30/V30+/V30S -- EXCEPT for T-mobile H932 -- can be bootloader unlocked and rooted. See here for

one smart blonde female Verizon user on V30 custom ROM

.

The LG V30 is the one phone with all the specs of the Quark + more. I didn't lose anything. OLED 1440p, Qi wireless charging, 4GB/6GB RAM, 64GB/128GB/256GB internal memory + microSD card, headset jack, quad DAC, IP68, fingerprint sensor, dual rear cameras with OIS. Bootloader unlock, TWRP, root, custom ROMs.

But you've still got plenty of time to switch! (end of 2019) Just want to let you be informed.

I'll let other actual Quark, Oreo ROM users answer the other questions.
