yes, I have this issue too. Tried resetting the Camera app (delete cache etc.), but to no avail. It happens less often now that I've formatted SD as internal storage, but still happens regularly, also during photo browsing. Was going to do a full reset while moving over to unofficial

When i plug in the phone while off it always turns it on automatically.

Flash stack from Orden thread that should be the China stack. The bootloader I use and everyone uses is from an early Oreo firmware ZTE gave me which has fastboot and it's mismatching with the current tz rpm...so offline charging is broken until you flash that.

I thought the fix for offline charging will break fastboot functionality again.

Would you mind providing the proper TrustZone RPM?

Getting ready to upgrade to 15.1 from a very old 14.x.

First post makes reference to flashing a new bootstack - https://androidfilehost.com/?fid=11410932744536985259 .

This file contains a fastboot.img image. Does this fastboot retain the unlocked message seen at boot (with shortcuts to recovery, bootloader mode), edl mode, etc?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Thenetstriker:
I've switched to LineageOS on my Axon 7 in december because of some weired issues I had with the stock Android version. Most of the problems I had are gone, but one very annoying problem still exists. Sometimes the phone just get's extremely warm during standby and drains almost the whole battey in one hour. The only way to stop it is to shutdown the phone, wait until it is cooled down, start it again and charge the battery back up.

I already replaced the battery a few week ago with a new one. The new battery now keeps it's charge longer and I hoped this would also solve this overheating problem. But it seams that not the battery is the cause of this problems. Does anyone have the same problem and how can I find out what is causing this?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] littlenoodles:
I had the overheating problem on the official LOS. Wouldn't happen all the time, and If I caught it - and did a 'clear all' on the multitasking list, it would cool back down and resume normal battery operation. Recently switched to unofficial, and it seems much better. Making it through a whole day on a single charge again. By the way, how hard was the battery replacement?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] gpz1100:
RE Battery replacement

I haven't done it myself yet, but am tempted to. The most difficult part seems to be getting the speaker grills off without damage. Some suggest heating it up to loosen the tape. I have some heavy duty gorilla tape (this stuff sticks tight). Going to try applying a piece the whole length of the grill, let it set for a bit then lift up.

The other challenging part is not to damage the ribbon under the battery. Again, heating the battery with a heat gun or hair drier should do the trick. I'd make sure the battery is fully depleted first, just in case.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Thenetstriker:
I just updated to the latest nightly build of LOS Android 8.1. But I don't think this will fix the problem. Also the battery drain on my device does not stop until I restart the phone.

The battery replacement was not too complicated, but as gpz1100 already wrote you have to remove the speaker grills with a heat gun. Sadly I overdid it on one of the grills and it melted on the top. But I found replacement grills on AliExpress.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Infy_AsiX:
complaints about rogue apps keeping wake lock and using high processor isn't related to the ROM. Such claims without logs or checking for faults is useless
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] les_paulde:
UD, I just migrated to unofficial and wanted to send a BIG thanks as this ROM simply kicks ass! Battery life more than doubled and performance seems equal, so I'm as happy as could be. Good luck these final moments before your new life and thanks again for all the hard work!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] HunterBlade:
Thanks for your work! Looking forward to the day when our device finally gets a vendor where everything works (VoLTE, WFC, etc.) and we don't have that annoying corrupted device message on Pie GSIs anymore.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] runninghamster:
Opening the phone in reality is quite easy, as long as you don't rush through it like I did lol. The speaker grills can be taken off without too much damage, but heat certainly helps a lot. Try not to heat the top grill too much because of the camera, but the bottom one you can heat a bit more. Try to work with something sharp, starting from the middle top of the grill or the corner of it (starting from the corner will leave some scratches).

The hardest part will be to separate the two halves of the phone, try to take your time with this and not just apply brute force and wedge your tool into the side like I did. Don't worry about the fingerprint ribbon, it's quite long and if you're careful it shouldn't be a problem whatsoever.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Choose an username...:
If anyone is using the latest Unofficial vendor on GSI's (or maybe on LOS too), did anyone notice some flakey cell data on it? I'm almost sure it's behaving really badly right now, as in pretty much same reception as always but disconnecting suddenly (e.g. 4G+, full bars or almost full, suddenly shows an X and stops working. also happened with HSPA+ and even G/E)

I just want to confirm this is something new.

Also [MENTION=4911249]Unjustified Dev[/MENTION] awesome work on it... You fixed idle CPU usage? It's as good as stock Oreo now, from what I could compare.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] krsmas:
Hey! A little confused about the whole unofficial build thing.

I'm wondering what the advantages and disadvantages are of using it, and if the installation procedure is identical. I'm also wondering if I can still receive OTA updates.

I've been on LOS for a few days now and for the most part I'm liking it but I do have a few issues:

* No offline charging

* Battery life has decreased from stock Nougat

* Message about the unlocked bootloader when turning on phone

* No Google Pay (relock bootloader?)

I'm trying to remedy these problems because otherwise the experience has been perfect. Can I simply relock the bootloader? Can offline charging be patched in somehow? Should I be using the kernel I have now?

Sorry for all the questions. I'm having trouble answering everything by searching online. Thanks for the help!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
Advantages and disadvantages have been discussed. Biggest disadvantage is that all of the advantages aren't going to be pushed into official builds, so once the dev stops working on the unofficial builds, that will be the last security update for you. Unless you move to official builds and lose all of the advantages.

Offline charging is a bootstack issue. If you want a bootstack with offline charging, you will lose fastboot. There are no bootstacks available that have everything working.

Battery life on Oreo is going to be less than Nougat no matter what option you choose. ZTE left us with crap, and the devs have done the best they can with it. As stated, the unofficial build has solved many issues, but, it will never be as good as Nougat.

The unlocked bootloader message will always be there. It's a message shown on many other devices. Only way to remove it is to be on stock, with it locked. There are some flashables going around to remove it, which i feel are unsafe. There are also a couple of bootstacks going around which have replaced the splash with another image. If using LOS, Oki's B12 bootstack works for doing this.

To use Google pay, you only need root with Magisk and hide Google Pay with Magisk Hide.

If you want more battery, I suggest Schwifty v4. You may notice the UI be a little slower, but it is great for battery. If you can't stand the slowness, then try v5. Just don't forget to flash back to LOS kernel before swapping to v5.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] krsmas:
Thanks for clearing that up. I'll give the unofficial build a try seeing as I'm I can just switch back if I ever feel like the need. I was talking about UnjustifiedDev's build in particular, and he seems like a very active and reliable developer.

Now, is disabling fastboot a viable option? Seems kinda dangerous to me. I'd still have access to recovery, correct? I definitely don't want to run risk of bricking my phone.

It really stinks that ZTE didn't quite deliver:( I'm absolutely grateful for all the hard work that's being done by the devs. I'll definitely throw a few bucks their way if there's a way to do so (I just read that UD has a baby on the way)! Battery life is my main concern and from what I read UD's build seems to greatly improve that aspect.

I would definitely prefer the splash. I'll check out Oki's work. Thanks!

Good to hear about Pay. I haven't rooted yet so I'll get right on that!

Not worried about the UI much but am I able to tinker around for more performance? I emulate and play a few games from time to time so I'd prefer to retain my performance when I need it. Basically I'd like v4 but also the performance when I absolutely need it. I remember using setCPU a long time ago and the elementalx kernel and I was able to mess around quite a bit.

Thanks again. I haven't done any of this stuff since the Galaxy S3 days when I was rockin' Paranoid Android and AOKP. I'm a bit rusty:^)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] krsmas:
EDIT: Post wasn't factual and was corrected below.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
The info about not getting root with Verequies B20 is incorrect. I personally use that bootstack, for quite some time and do not have those issues. With that said, it is a B20 bootstack and not recommended for use with LOS, which may be where those issues came from.. if you read it somewhere.

Just wanted to note that Schwifty v4 has more tweaks to choose from, if you're into further tuning your kernel. You won't find as many options in v5. With v5 you will get some insane standby time, depending on what ROM or vendor you're on... I think it's partial to LOS based ROMs and vendors. But, YMMV.

Happy testing.

[MENTION=4911249]Unjustified Dev[/MENTION] is there any chance to fix dual SIM support in the unofficial build? Is there anything we can do to help?

@krsmas What is this flash issue? Flash occurs too early or too late to illuminate subject?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Choose an username...:
If you relock the bootloader while not being in completely stock firmware, you'll be having an expensive paperweight. keep that in mind.

that said, you can bring it back, but it's better if you don't get there in the first place

Ofdline charging and the 5 sec screen can be fixed by the bootstack

---------- Post added at 08:05 PM ---------- Previous post was at 07:33 PM ----------

It'd be better if you didn't present your findings as facts, because they sure do sound like that. This post will stay here as-is and people might believe stuff is like that...

First and foremost, the flash is broken on GCams, but not on every camera. Try others, I've read reports that it works on the Nokia camera. Sometimes works on Whatsapp, and I think Open Camera also does the job (don't take my word for this last one though)

Offline charging is enabled by some bootstacks while they break fastboot too, but you don't lose root by flashing Verequies's bootstack! Or safetynet pass... The unlocked bootloader has nothing to do with safetynet, and neither does the bootstack, as you can usually fix cts mismatch by flashing MagiskHide Props Config and setting your props to the 8.0 axon7 props. Also having no fastboot is pretty much not a problem as you also have twrp most of the times, and you always have EDL/DFU available.

Even if you don't fix the safetynet fail, you can still download Netflix from apkmirror and be done with it, so it doesn't "render Netflix unusable".

To remove the splash you can use Oki's B12 bootstack or Verequies's B20 Splash No Message bootstack. I think both have fastboot, but they don't have offline charging. Now, this is just common sense, you lose the ability to enter the modes via a simple UI, but you already have key combinations for EDL, FTM and recovery. you don't really need fastboot for anything as EDL Tool already has the capability of flashing recovery, and then you can flash images via TWRP. Or you could EDL flash a bootstack with the 5 sec screen if you really needed it.

And for more battery life you can flash other kernels, not on stock+ or mifavor because nobody bothered to make kernels for them. only custom ROMs. There's Schwifty and Hellsgate.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] NotRankin:
Hi, really appreciate the work put into this. However, I do have a question, as this issue has persisted through Official/Unofficial builds, as well as AOKP, and (afaik) the kernal LOS uses and Schwifty v5. Issue is, my phone when rebooted will sometimes do either; sit on the penguin forever, or start the boot animation and sit on it forever. I can force shut off the device and try again, and it eventually (usually the 2nd or 3rd try) will boot normally. Not sure if I screwed something up on the install process? Using A2017x_LineageOS15.1_UniversalBootstack_v2_by_DrakenFX.zip as well as well as A2017U_OreoModem.zip. I've been digging through the thread and I can't find out what's going on, if anyone else is having this issue, or I'm searching with bad keywords. Thanks.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] NotRankin:
I did before, but I believe I swapped to something else (AOKP or clean flash into another unofficial) soon after so I never actually noticed if it worked. Trying it now.

Unfortunately, it didn't work (I think). Worked for 6 normal reboots, but when updating Youtube Vanced via Magisk and rebooting, the phone sat on the boot animation for 15 minutes before I forced it off. Reboot after worked.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Infy_AsiX:
I highly recommend Crimson kernel for the EAS performance. The kernel source since going Treble if I recall correctly has lowered performance. With EAS you only need to adjust the topapp boost value to scale how much performance you need. With current HMP kernels I can't manage to tune any for gaming performance.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] emanresu2:
What's the current state of the latest unofficial build? As in, are there are any major bugs or lost features in moving to it from stock? The most concerning things I've read about in the past were speaker issues, GPS issues, Daydream support, and dual-SIM support. Is all that mostly cleared up now? Thanks in advance.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
Well, it should get rid of the penguin. If it comes back, there is something more dire messed up with your setup. At which time you should consider wiping it all and starting fresh, or maybe use an EDL package to get back whatever is messed up, which will be basically wiping and starting over anyways.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] NotRankin:
When you say it should get rid of the penguin, do you mean never show it at all, ever? I know for a fact when I tried the code you gave the first time several weeks ago, it never disappeared, and when I used EDL mode to get back to stock (was tired of the issues, but then I discovered the magisk issues on 7.1.1+. The EDL package/guide I followed: https://xdaforums.com/axon-7/development/edl-emergency-dl-mode-twrp-unlock-t3553514) a week ago, and restarted, it's still there, even now after entering it in TWRP Terminal. Would entering it in terminal in TWRP be causing issues? Thinking it might work over adb? Wondering if it has to due with the issue I'm having of TWRP rolling back to other versions randomly..
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
Yeah it should have gone away permanently.

I'm gonna suggest you follow Okis guide here:

https://xdaforums.com/axon-7/development/unofficial-lineageos-15-1-zte-axon-7-t3800214/post77731728

Make sure to follow all of the steps carefully. Only thing i would change is where he has you format to f2fs, do so, but then format back to ext4.

Afterwards, then flash the latest LOS rom of your choice. When you flash LOS it replaces your TWRP I think, this might be what you're experiencing. Just make sure to flash your preferred TWRP after you follow Okis guide and after you flash LOS.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] NotRankin:
Holy ****, thank you. Penguin is gone (glorious gold splashscreen on boot instead, had to remember the button combo for recovery) and phone is booting much, much faster. Here's to the bootloops stopping too, thank you so much!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
No problem bro, all thanks goes to Oki for providing us that great starting point. The golden Axon splash is his custom B12 bootstack. It's a good one to keep if you want it, i believe most everything is functioning fine with it. Just gotta use key combos, as you already discovered, and no offline charging. Which, i don't even know which bootstacks offer that anymore since treble. Anyways enjoy.

^^Without offline charging, what happens if the battery runs down completely?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Predatorhaze:

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] gpz1100:
Help me understand. I thought offline charging was charging when the phone is off. If the battery is completely run down how is it going to turn on to charge¿? A bit of a catch 22, no?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
In most cases, phone will boot and still have enough juice for you to continue charging.

If battery is really dead, you should still be able to boot into recovery as a workaround and it will charge there.

Any deader, well, you must have really messed up plan A B and C somehow by booting your phone over and over without being on a proper working charger.

In other words, you should take care.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] gpz1100:
Let me put into context my comments above. I just replaced the battery in my device. The new battery was completely dead. I got one small vibration then it shut down. Without being able to charge it while off, I suspect it would be impossible to charge it at all.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] HunterBlade:
Doesn't this bootstack still support offline charging? https://androidfilehost.com/?fid=1322778262904015006

Seems like the only thing you lose though is fastboot (which really shouldn't matter much since you should already have a custom recovery and EDL mode if necessary).
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
I've never used that or know anyone who has. Feel free to let the rest of us know how it goes... Lol

But yeah, no need for fastboot.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Infy_AsiX:
i think those are fine on latest unofficial. I don't use some of those and only from memory reading here
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Choose an username...:
well then you suspect wrong. Charging always works. Even if the battery is way below the threshold or whatever, your phone is going to boot successfully because it will have 18W available from the charger itself... You can use the phone without even having a battery attached.

Just connect the phone and let it charge for a day, and if it keeps doing the red LED thing then you should suspect something else like a badly connected screen or something that would prevent the phone from booting

Just updated my ZTE Axon 7 to the latest build (20/2/2019), and just updated it on 21/1/2019. Then today I plugged it into my car via AUX and no audio will output into my car. Everyone else's phone works in my car except mine since I updated it. No matter what app I use, audio does not output. Was wondering if anyone has the .zip file for 20/1/2019 as I have an 8 hour car trip in 2 days.

I installed Lineage OS 13/2/2019, and the audio worked through my headphones for about 30 seconds of one song and then it just stopped playing. Nothing comes through my earphones now...

I have also cleaned the headphone jack and it didn't fix it.

Also I'm very out of the loop and I was wondering, why am I getting an update everyday for the Axon 7. All I want is stable updates.

EDIT: Just updated to 21/2/2019 and I had 2 songs work the whole duration. Took it out went and bought some pasta. Hoped back in my car and tried to play a song and it just didn't play. I can hear about 200ms of a song each time I tap play and pause really quickly
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] tprfd:
There was a fix for audio fx that seems to have broken the headphone jack. It went in on the 13th.

I can see in code reviews they are reverting that update but unsure when or if that would go into the next build.

https://review.lineageos.org/c/LineageOS/android_frameworks_av/+/241802

Try turning off audio fx if it is on, wait another day to see if is in the next build, or find a cheap 3.5mm to Bluetooth adapter for your road trip.

You get updates every day because lineage is on a nightly build schedule. Usually nothing changes from day to day for 15.1. There is no 'stable' snapshot build like there was with CyanogenMod so you are taking a slight risk when you update but usually that risk is super small.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] SugnaB:
Thanks [MENTION=4449260]tprfd[/MENTION]

That stupid audioFX app was the culprit. Was set to on and was obviously causing a disturbance. I remember first installing Lineage and remembering you couldn't disable the app. Thanks for the help, would have lost my **** if my phone was broken.

Also is eleven music player still being developed. Its my favourite ever music player but, my god. The amount of bugs in it.
