o I was on nougat beta2 A2017G (full stock, locked bootloader).

o did backup of gpt, boot and recovery with axon7tool (https://xdaforums.com/axon-7/development/axon7tool-flash-backup-boot-recovery-t3514254)

o flashed the signed twrp (twrp-3.0.2-2-signed.img) with axon7tool, because this one started with locked bootloader.

o booted in recovery (twrp) and flashed TWRP_UnlockBootloaderPackage_by_DrakenFX.zip (https://www.androidfilehost.com/?fid=24723757092307343)

o booted to bootloader (fastboot) and did unlock

o booted to recovery formated data, cache, system and flashed lineage

When I read the audio was distorted, I wasn't actually expecting it to be as bad as it was!

Not knocking LoS or AOKP, both are really amazing builds, but I have come to realize that I will have to wait until that is fixed.

The speakers are the #1 thing I got this phone for, so I'll have to lose root on Android N until a compatible TWRP or a custom ROM stock ROM (or the audio gets fixed on these ROMs).

Not a very helpful post, but just an observation form a self-proclaimed audiophile that couldn't live with the speakers.

FWIW: I did try V4a and ARISE, but you had to lower the volume too low.
[ZTE Axon 7 Questions & Answers] borijess:
I am rooted and installed viperarise but app not working. It's still distorted. I am on 14.1.
[ZTE Axon 7 Questions & Answers] strifej:
I'm using the root from the lineage extras. Has anyone tried supersu? and how would one go about switching to supersu?

I used the lineage one because others have said the supersu wasn't working, but lineage did.

---------- Post added at 12:27 PM ---------- Previous post was at 12:26 PM ----------

When you check viper4 status, does it say Processing: Yes when you're playing from the speakers? Mine doesn't.. prob. why we still get distortion. But I haven't found it to be too big a problem.
[ZTE Axon 7 Questions & Answers] jawz101:
I don't know why you'd use a different su. Especially a closed source one
[ZTE Axon 7 Questions & Answers] tele_jas:
I had to restart a few times before it kicked in... Start playing music, then open the V4a app and turn on the master power.

This doesn't fix the distortion, but you can adjust the gain down (pretty far), which basically just lowers the over-all phone volume and doesn't allow it to distort. If you use your phone to listen to music, this "helps", but is less than half the volume of the Stock ROM.
[ZTE Axon 7 Questions & Answers] sgarrand:
Not specifically Lineage related but has anyone ever figured out how to disable a sim slot on Lineage?

I use T-Mobile Digits to act as wifi calling in the basement at work. If I don't disable the sim, the app won't work. In stock MiFavor there were toggles. I don't remember seeing that in the CyanogenMod days either. Can't find an app to do it and the hidden phone menus have some similar settings (turn off radio) but Digits still sees the sim.

Once we get wifi calling this will be moot but it could be a month or more. Thanks.

Edit: Even airplane mode does not work. Dang it. :)
[ZTE Axon 7 Questions & Answers] xtermmin:
I asked a similar question back when CM13 was released. Can't find the link now, but paraphrasing: prior to Marshmallow, the part of the modem code that this function was in was open source, so ROMs like CM and LOS (as well as OEM ROMs) could access and use the function. After the move to Marshmallow, that code was moved into a closed-sourced binary, so CM/LOS no longer have access to it.
[ZTE Axon 7 Questions & Answers] adriangb:
So it seems that [MENTION=4911249]Unjustified Dev[/MENTION] has said audio volume o speakers will never be fixed. Thoughts? Is anyone going to stock N just because of this?
[ZTE Axon 7 Questions & Answers] sgarrand:
Not sure if he said/meant never. Someone said they hoped audio would be fixed on Monday and he said that it won't be fixed. He didn't specify if it can't be or won't ever be. ZTE has been cooperative and they could help out, they just have not yet.
[ZTE Axon 7 Questions & Answers] iNaruX:
People are blowing Audio out of proportion. Headphones are on par with the normal setting on stock ROM.

If and only if ZTE cooperate further, we will get better audio. It's not up to UD, he did his part. You could try and pressure ZTE / negotiate with them.
[ZTE Axon 7 Questions & Answers] jawz101:
Go to settings > sound > phone ringtone

Pick Twirl Away, for example

Set your ringtone volume to 100%

Do your speakers sound like they'll explode?

We're not talking about headphones. There are various audio streams that are configured with volume gains and steps independent of one another. It's done in xml files and .conf files. We don't know the proper settings.

People have been bolting on these sound add-ons to lower them with 3rd party workarounds but that shouldn't be necessary. Besides, I'm not even sure that would adjust the ringer stream max volume or number of steps or the notification stream or when your in call and turn on speakerphone.

Headphones are fine, Bluetooth audio volumes are fine too. It's the speaker audio streams which are not calibrated.

Now, people are also muddying the conversation of sound by going on about wanting Dolby ATMOS and hifi DAC junk. That's out of scope but when we talk about distortion and crackling there's a speaker volume problem.
[ZTE Axon 7 Questions & Answers] iNaruX:
I never even set the volume to 100% on stock.

I am just happy that I don't get the crippled European volume anymore. Finally the loudness is acceptable.

I do notice crackling when I play anything from speaker above,say,80% volume.

Still, it's nothing to keep you from flashing LOS, the pros outweigh the cons imo. The temporary fix is easy: Keep your volume down.

I am pretty sure UD is trying his very best :)
[ZTE Axon 7 Questions & Answers] adriangb:
Thanks, I just wanted clarification. I've used LOS since it was first released, I know what the deal is, and I wasn't doubting U-dev, just asking for clarification since it sounded like he said it would never happen, independently of time or ZTE cooperation
[ZTE Axon 7 Questions & Answers] jawz101:
I don't know the answer to that. Perhaps he's referring to everyone asking about getting the DAC/hifi audio/Dolby ATMOS proprietary stuff people want to magically have in an open sourced ROM. I'm pretty sure ZTE and LineageOS would be sued if they start handing out code for that stuff.

Dolby is its own company which makes audio processing technologies and ZTE bought license to use it in their ROM.

Actually, I wouldn't be surprised if all of the Dolby sound mods were ever issued takedown notices as it's basically pirated software. Heck, they may not even actually work the same as they do in the stock build if their are bits of code not known about to turn on. Sure, our phone originally had it but

1- that was a product exclusively of the stock ROM

2 - it's being packaged by xda users to work on other phones.

Bottom line, if you bought the phone for sound you better stick to stock. Regular speaker volume and stuff, however, shouldn't be left where your speakers could explode when you get a phone call. That code is tunable and open source Android stuff.

I just know enough to say that. Not necessarily do it, though :/

Sorry if this has been brought up before but is anyone else having storage issues on Lineage? My internal storage shows -34.52GB out of 14.84GB, -35.41 of which is under "others". I have a 16GB microsd card installed and the storage numbers seem fine on file explorer tho. The whole ROM works great and I'm able to install apps no problem but I'd just like to know if this a bug with the ROM or if I fked up somewhere.

Edit: Found a temp fix on the official Lineage thread on page 103, post #1029 by TheHaloMilitia. Simply remove the sd card, reboot, reinsert sd card.
[ZTE Axon 7 Questions & Answers] MaxRink:
is F2FS back in LOS or is it still not supported?
[ZTE Axon 7 Questions & Answers] jawz101:
It's a known issue. Well, there are several people in the other thread who have reported it. Mine's been fine, though I did not to install the Google storage manager using aroma opengapps package and uninstall the stock one. I don't know if that makes a difference.
[ZTE Axon 7 Questions & Answers] jawz101:
I didn't know. I think it is but I'd wait to try when the 1st official release shows up on https://download.lineageos.org/.

Is Substratum working? For me for each downloaded theme gives error: The overlay compiler was not found on your system! Substratum tried to inject it but failed twice.

I have root working properly (I tried with SuperSu and with Lineage ARM SU 64 bit also with the same result).

I am on Lineage-14.1-20170203-UNOFFICIAL-axon7

A2017G version
[ZTE Axon 7 Questions & Answers] jawz101:
I'd look at the Google Community in the OP. Your mileage may vary because you're fighting Nougat, not LineageOS, and definitely not this particular phone.

I was trying to do this https://www.xda-developers.com/how-to-add-more-steps-to-your-volume-slider-root/

Has anyone had issues with adaway? I get a copying of hosts failed message. I'm using the lineage root adon & my other root apps work, so I'm not sure what's wrong.

Edit: I installed SuperSU on top of the LineageOS root, seems to have done the trick.
[ZTE Axon 7 Questions & Answers] nupi:
Works for me with lineage su, I presume you did disable emmcpp?
[ZTE Axon 7 Questions & Answers] Harmtan2:
I did, but I did have to reflash, so maybe I need to do it again. Although, SuperSU on top of it did the trick.
[ZTE Axon 7 Questions & Answers] nupi:
No I don't think it goes back to being locked by itself... Strange that lineage su didn't work.
[ZTE Axon 7 Questions & Answers] iNaruX:
Strange..wanted to go from unofficial Feb.03 straight to official and it doesn't let met. Says it cannot be installed on top of existing data in TWRP.

But you should be able to switch from and to official seamlessly? Do I first need to flash more recent unofficial builds before I can hop on to official?
[ZTE Axon 7 Questions & Answers] spacemanvt:
I believe you have to flash the experimental build then flash the official.
[ZTE Axon 7 Questions & Answers] AxonVeezy:
Sorry for the dumb question. Long time reader of XDA, new to axon and first post here!

Anyway I just made the switch to Lineage after being disappointed in the stock N update. Immediately I notice a significant difference in smoothness.

I do however have one question... please excuse my ignorance. I've searched and read this forum before posting this but if I missed something please accept my apology in advance..

Anyway I unlocked and flashed TWRP using the EDL method and then simply flashed Lineage (unofficial, then official experimental then nightly). I didn't bother flashing the universal boot loader or modem. Should I? I assumed that was only if you were coming from B29 (I have us version). Not having any issues that I can tell at this point.

Anyway great ROM and thanks in advance!
[ZTE Axon 7 Questions & Answers] yamils:
if your phone boots up and everything work OK, then no, you dont need to flash the fix.
[ZTE Axon 7 Questions & Answers] AxonVeezy:
Ya that was my initial thought, but figured I should ask.

You need to flash the experimental build and then flash the official.

2. Experimental

3. Nightly

[ZTE Axon 7 Questions & Answers] sourbear:
A couple of issues I've run into since I'm running the Official nightly now...

First: I used Open GApps (arm64) (7.1) Aroma for February 10. I've noticed in the installed Play Store settings that there isn't the option to turn off Auto-update of apps. The only options in Auto-update are to 'auto-update any time' or 'auto-update over Wi-Fi only'. The option to NOT auto-update is gone. Is this a Google change? An Open GApps change? A LOS change? Is this permanent or is this something I can fix?

Second: The LOS on-screen nav bar/buttons (back/home/apps) make Snapchat's chat/camera/stores buttons inaccessible because the LOS nav bar/buttons overlays over the Snapchat buttons. And because I'm using an Axon 7 that doesn't have hardware nav buttons, I have to use the LOS on-screen nav bar/buttons. I sent [MENTION=4911249]Unjustified Dev[/MENTION] a message about this issue because I don't know where to officially file a bug report specifically for LOS and the Axon 7.

UPDATE: First issue has been figured out thanks to someone in the Open GApps section... It is an individual app setting now, so open the page in play store for one of your installed apps, then press the overflow menu (three dots).

Second issue has also been alleviated a few posts after this one, by using LOS' expanded desktop settings. Still not idea - because I don't have hardware buttons so when Snapchat is open and the LOS nav-bar goes away, to be able to get back home, I have to have a way to get the LOS nav-bar back on screen and to do this, I have to pull down the notification shade, nav bar shows back up, then press home - but it works.
[ZTE Axon 7 Questions & Answers] lafester:
Just go into expanded desktop and enable for the apps you want.
[ZTE Axon 7 Questions & Answers] sourbear:
Well that certainly helped me with the Snapchat issue. Thank you! Still learning LOS so didn't know about the expanded desktop settings.
[ZTE Axon 7 Questions & Answers] AxonVeezy:
Anyone else having an issue as it relates to the signal bars? Mine drops to 0 all the time, but it still seems to be working. On stock in the same locations I always had at least 2 / 3 bars, but with Lineage I notice the signal bars jump around a lot. It's hard to tell if I've actually lost a signal or not.
[ZTE Axon 7 Questions & Answers] jawz101:
Is that for the US version or G version? I'm trying to keep a running list of versions as they come out. Where'd you get that link?
[ZTE Axon 7 Questions & Answers] jawz101:
on that 2nd issue I'd check the OP for the link to the LineageOS JIRA issue tracker. It sounds like a general LineageOS issue that could be most effective there as the JIRA issue tracker has the attention of the whole LineageOS team.
[ZTE Axon 7 Questions & Answers] dbloms:
I found it here https://xdaforums.com/showpost.php?p=68873485&postcount=3

So I think it is for G version.
[ZTE Axon 7 Questions & Answers] sourbear:
Yes. My cellular signal icon constantly does this. Haven't had any issues with my Wi-Fi signal icon. This was also an issue on ZTE's stock ROM until they did an update and made changes to how the icon showed signal. The signal itself wasn't improved in that update, just how the icon showed the signal. Bars aren't a true representation of signal strength. dBm is where it's at and I've noticed my dBm on ZTE's stock ROM would be anywhere from -99 to -108 when at home. On LOS, it's anywhere from -114 to -119 at home. This tells me cellular signal strength is worse on LOS than on ZTE's stock ROM.
[ZTE Axon 7 Questions & Answers] Slick52:
Has anyone gotten Google Assistant working on LOS? Even Google on Tap would be nice, but holding down the home button only ever displays the app switcher. I've tried different launchers and on screen nav buttons with no success.
[ZTE Axon 7 Questions & Answers] jawz101:
This may be obvious but did you have to go to settings > apps > hit the little cog wheel in the upper right corner of the screen > Assist and Voice Input and select Google App as your assist service?

I try the Google App occasionally but end up uninstalling it because it's the primary Google app that wants you to turn on all of Google's data gathering and that particular assistant permission says it says wants to observe what's on your screen to perform contextual searches on any app. Kinda bugs me.
[ZTE Axon 7 Questions & Answers] bluestudy:
If I had to guess, it's probably long press home activity. It's been set to recents by default on every ROM that I've installed.
[ZTE Axon 7 Questions & Answers] Slick52:
I did check that and the Google app was already set. But, then I looked under the button settings and found that I could change the long press home button setting to Search Assistant and that at least launched Now on Tap for me. So now I just need to try to enable Google Assistant. Thanks, you got me thinking in the right direction.
[ZTE Axon 7 Questions & Answers] jawz101:
I think they changed things up in nougat and put it configurable there. Like, not LOS but Android made that change. Heck, MiFavor probably hides that screen because they did hide some standard Android screens in Marshmallow.

Can someone please give step by step instructions how to go from LOS to stock Nougat.

I have TWRP 3.0.4 and LOS is working ok. I really miss speaker quality so I decided to go back to stock

Tried to flash Draken's systemstock Nougat ZIP and suck on boot.

My understanding is that only thing needed to go from LOS to stock Nougat is to flash that ZIP...

It is US version of the phone.

Nooby question that probably isn't LOS-specific: it seems that if I don't mess with my A7 (running LOS) for a while, it falls into such a deep sleep that push requests (gmail), and pull requests (RSS Reader, other apps) don't update until I unlock (wake) my device. When I do so, my push requests come in, and when I check my apps that pull, I'll see that they haven't attempted pulling in hours. Haven't had this issue on other phones running CM/their stock ROMs, and auto-sync is turned on for gmail. Is there something I have to do to get them to wake up my device for an update?
