Battery life has improved drastically with the latest build (4/6). I have been struggling to get more than a few hours SOT, for example, since Oreo testing began (stock kernel). Standby battery drain was rapid.

I'm now back in the 5+ hour range. My usage and app lineup hasn't changed, so I'll attribute the gains to the ROM itself. Standby time has improved as well. :good:
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] aLexzkter:
Hmm. I'm on the previous build and my battery life is bad.

"mobile network standby" is what takes out more power from my battery apparently by the way.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] AnonVendetta:
[MENTION=4676535]Cablespider[/MENTION]: What the hell are you doing to get such awesome battery life? I'm running 04/06 build and it has been only 10 hours since my last full charge, I'm already at 7%. I flashed the ROM yesterday when it was released. I use all-black themes/apps wherever possible, no GApps, only essential apps, lowest brightness i can tolerate, no Xposed, but battery life still isn't that good. I only do full charges.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] troy5890:
Battery life has been pretty good so far with this ROM. Yesterday I managed to get 5hrs and 28 min of SOT. This is without the Jojoc V2 zip. Thank you NFound
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] dwnoel:
Yes for sure it is. The ROM is smooth, fast, sober and nice. Only known issues are no encryption and dual Sim limitation. I m using Chromecast w\o any problem (was crashing with rays Oreo ROM).

As mentioned in posts today's, autonomy is now quite OK (count 20%/h sot, 0,3%/h by night plane+saver)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jrotaetxe:
And my two cents.

Is the ROM of choice if you want Oreo. Even using two SIMS, deserves. What I like most is the sober it is. But let you tweak enough if you want.

Thank you, NFound and AEX team. Is a fine, fine ROM
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Cablespider:
I use Magisk mods, Greenify and Enable Doze for Google Play Services. To be honest, I don't even know if they have much of an impact because I have never tested without them. I probably should. Auto-brightness is enabled and all the ambient crap disabled. I freeze what I don't need with TB. I clean install almost every build. No voodoo here.

I'm using the official TWRP 3.2.1 image, NFound's Oreo bootstack. GZR Zero Gapps, and the stock kernel with out of the box settings. No tweaks. I'm a minimalist when it comes to installing apps. Based on my scenario, I have noticed great improvements in the battery department. Like night a day from 4/2 to 4/6.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
I would also like to add, for anyone using the Viber app, it will not work on carrier data, it will only work on WiFi. This has been the case with every Oreo rom I've tried, and have confirmed others having the same issue. I'm sure it's nothing the devs want to bother with right now, and may just have to wait until the official Oreo.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] 2CanSan:
I agree 100% and this is my 3rd dirty flash with no problems. No greenify or anything else. Solid Rom
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bramhc:
Can boot to system&interface but missing TWRP and can't install TWRP

The situation is very strange. I flash oreo bootstack, after that flash the ROM (AEX 5.4). After I reboot to system, it ask for my encryption password. Rightaway I know I have to go back to TWRP again, flash Data partition, and call it a day. Then the strange comes.

I can't enter TWRP. It's just black screen with red LED flash for a few seconds then power off. With panic, I attempted to unlock my bootloader using Axon7Toolkit. It successfully unlocked, and after I reboot it again, it just enter to system rightaway. Yeah, RIGHTAWAY, just SIM Setup and go. And THE DUAL SIM WORKED! Strange huh?

Already entered to the interface, I reboot to bootloader, attempted to install TWRP from fastboot. The Command Prompt says it's successfully installed. But when I press Power+Vol Up, it going back to the same red LED flash again. But I can boot up to system and interface just fine. Just no TWRP and no root :(

ANYONE PLEASE HELP MEE

So just to be clear, we can dirty flash the updates on this ROM. We dont have to clean flash with every update? Thanks guys, LOVING this Rom!!!!!!!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Spooderman46:
This may be a bit off topic, but if I want to run this rom coming from RR Nougat I'm gonna have to do a clean flash. Problem there is my Spotify, I haven't found a way to successfully back up downloaded music have tried everything but nothing works, this kinda limits me cause to download all my songs it's a 10gb download :(

Has anyone found a way to backup Spotify successfully?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] thehritzinator:
So if I am coming from RR Nougat, the steps would be this? A2017U

1. Install B32 bootstack

2. Wipe Data

3. Install Rom/Gapps

4. Wipe Cache

5. Reboot

Is that correct placement of bootstack? Should I install bootstack before or after wipe?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] marcdw:
Do you know where the downloaded music is stored? If it's under /data then yeah all would be lost with a clean flash.

If they're stored under /sdcard (/storage/emulated/0) somewhere then all should remain.

I don't use Spotify so I don't know how it handles its files. I would probably try to copy the directory holding the files to a work location on SD card or flash drive. Copy back after app is installed.

Works in some cases but not all. Especially if some kind of file permissions are in play.

Hopefully someone has done this before. You'd think there'd be an app for this.

Yes bootstack 1st. 2. needs to be advanced, wipe system, wipe Cache and dalvec, then Cache further down list. 3. install ROM and gapps 4. factory reset, then boot system. FYI, the bootstack, had me on stitches lol. Pick correct model, and last check box at the end, MAKE SURE YOU SELECT THE BOX ON THE RIGHT!!! I selected the left, and it booted before I could finish flashing my zips.

Have a little problem with camera app. Shutter has a 1-2sec delay...do you have same delay too?

I would like to use google cam hdr but can not find better settings for minimize noise, stock is better.

So can someone recomend the best setting of G-cam HDR or what camera app is best for our AXON?

Thx a lot.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
As stated, ever since flashing Oreo roms, I have not been able to use it while on data. I have also had others confirm the same issue, even on RR, Candy, etc. Please PM me with your setup, as this is a minor issue and not worth cluttering up the thread.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Teet1:
I think the problem is that in oreo, mobile data is set to IPv6 only in APN settings. If you set it to IPv4 and IPv6 it might work. See below. You might have to create a new APN with the same settings but with APN protocol to IPv4 and IPv6
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] EBeatFLA:
Thanks, but I have already Googled and found this fix. It does not apply because my settings are already at 4 and 6 after flashing. I also tried creating a new APN as suggested in the fix, which did not work. The users on those sites also reported that other voip apps such as WhatsApp were not working before the fix. This is not the case for me, WhatsApp works fine, it is only Viber.

I noticed that [MENTION=5492451]NFound[/MENTION] has posted multiple bootstacks on AndroidFileHost, but I'm not sure which is the recommended/correct one.

Hey, does anyone have any guides or something on compiling this rom? I want to try getting into building Android ROMs myself but I have no idea where to start. Last time I tried (following a guide and trying to adapt it) I got a bunch of compile errors (related to GPS, without any modifications) and just deleted everything to start fresh.

Edit: looked over the code real quick, my issue might have been fixed already. Going to try rebuilding when I have time
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Oki:
That workaround sucks, Spotify reset V4A after every song and it is not stable at all. Just follow the guide I wrote more than a year ago for Nougat. It still works the same way in Oreo. You will find the Viper4Android 2.5.0.4 driver already installed and configured after the flash. Viper4Android 2.5.0.5 will work like a charm after rebooting the system. So ATMOS if you need it. I hope it helps.

Peace

I've been hoping for a real long time that eventually hi-fi audio can be played back, but not yet it seems :( theres a lot of Oreo blobs being added so I've been hopeful. I can't wait to see that soon, hopefully with the release of Oreo. I know audio is a mess, I just wished we knew what it was
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] JTruj1ll0923:
Well 1.3 works, it just has some stutters. So nothing that I wouldn't consider 'working'. However 1.3.1 just crashes all the time for some reason.

very dumb question:

whats dirty flash? install without wipe?

whats clean flash? install with clean wipe?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] troy5890:
Dirty flash is when you wipe dalvik cache and cache and not the other partitions like data, system, etc when you're flashing a new version of a custom ROM. Clean flash is when you wipe all of the partitions(except internal storage and MicroSD card) to install a new ROM or a new version of a ROM.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] aivilon:
ah well thanks, so i was right with my assumptions ?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] aLexzkter:
I don't think you strictly need to wipe data partition to call it "clean flashing". Wiping data but not system partition is not clean flashing but the other way around is.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] troy5890:
Ah I see, I didn't know that completely. Thought that was added into clean flashing to avoid any complications.

The person trying to call told me it said that the line was busy. I just clean flashed again and still no VoLTE icon. I just tried another test call and the other end could not hear me.

Dude Dude it doesn't always work like that Dude. And the thing you said about the 1% is horribly wrong...

Most of the times that your phone has wrong battery reading you need to delete the calibration file after charging to 100 percent. it's happened to me so many times over the years that i know that it works. The 1% statement is horribly wrong since the phone shuts down the phone based on the battery voltage, and that isn't wrongly displayed anyways.

Usually experience > theory, don't bother...
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] TPMJB:
If you have the 1% issue, reboot into recovery and try to charge it that way. I had that issue once and recovery + charge resolved it.

Leaving it plugged in while "off" did not. Not sure what the actual issue was, but I think my Samsung Epic did this from time to time on certain roms.
