Found one bug I think:

While playing music via headphone, when I clicked a picture with camera sound on then after camera sound song started playing via both main speaker and headphone.

By the way great battery and performance.

i search a few. And i found this, so i think i can't install official LOS 14.1 on my unofficial LOS 14.1. It's jus be done on cm13 :(

see you later

Mobile Data not working

Mobile data is not connecting .WiFi works fine but mobile data works only after first boot.

Any workaround
[Zuk Z1 Original Android Development] themonsterit:
be sure you have baseband 0.1.c1.10-00004-m8974aaaanazm-1 , this is what i have now after the whole update sequence

cause los14.1 official do not flash any baseband modem/radio firmware.
[Zuk Z1 Original Android Development] TrojanPL:
I have this baseband and I face serious GPS problems.
[Zuk Z1 Original Android Development] axolotl98:
Thats exactly the phones baseband...

Hmm any other ideas? Any app to install that can check on the GPS sensor?
[Zuk Z1 Original Android Development] axolotl98:
Ok guys. Installed many GPS apps, the best and most helpful one for me was the GPS Status app and the Z Device test. The last one verifies that the GPS sensor is functional. The GPS status shows information as sats in view and sats tracking, accuracy as well as an amazing feature called DOP dilution of precision.

This app showed me the following. I verified that it takes ages for my ZUK to track a minimum of 3 satellites, the necessary minimum number to get a fix and the coordinates of your position. From that point onwards it fixes up to 9 satellites, while the accuracy remains a horrendous 150 meters!!!

The way I understand the issue, there is a bug in the last several versions of the OS. I remember that the GPS worked OK with the unofficial LOS. Any help or advice moving forward is much appreciated
[Zuk Z1 Original Android Development] TrojanPL:
I also remember that I did not face any GPS problems on Marshmallow and Lollipop ROMs. The fix was very quick.
[Zuk Z1 Original Android Development] axolotl98:
Update: installed also the GPS Data app. This app amongst other things shows the signal strength received from each satellite. Compared my ZUK with my wife's Nexus 6 and the ZUK locks on to fewer satellites and the signal received from these satellites is much weaker I'm comparison to the N6.
[Zuk Z1 Original Android Development] themonsterit:
i think you should do a test with zui, this will confirm if zui is needed or not in order to initialize the gps firmware or not.

i read some old posts with gps problems, and the solution was to reinstall old zui firmware in order to reset gps.. i never trusted it, but a lot of people wrote that zui do something more with the baseband than los/cm, maybe some initialization in my opinion.

so do a twrp backup of the phone right now, install zui 215 with twrp, run the gps test app on zui, if it works properly you can restore the twrp backup... i think the hardware should remain initalized with zui parameters... if also zui is not working this means you have a problem with the gps antenna..

let us know cause it's a good test case
[Zuk Z1 Original Android Development] TrojanPL:
I have the same baseband as I had on Marshmallow and Lollipop ROMs and GPS is not working properly. Previously I did not have any problems. I think it is ROM issue.
[Zuk Z1 Original Android Development] themonsterit:
i'm using the same rom everyday and it's working properly.. everybody who skipped zui installation reports problems...
[Zuk Z1 Original Android Development] [DAO]:
Hi guys. I have Zuk Z1 as my back up phone. And i didn't update it for awhile (aprox an year). Now I see that there are Lineage 7.1.2 and I flashed it over CM 13 (6.0.1). During instalation i faced with some strange errors in log (unknown comand) but everything works fine at the end. I thought maybe I should update radio or bootloader but didn't find. Could you please clarify - is everything ok or I should do something additional to that I've done?
[Zuk Z1 Original Android Development] krishnamn:
encryption?

encryption willbe enabled in feature builds?
[Zuk Z1 Original Android Development] axolotl98:
Thanks a lot guys. Great help and team support.

I have installed according to your suggestion the ZUI v2.5.358ST (what a hideous OS, yikes...)

And then reinstalled from my backup my LOS. It seems that my GPS has been awakened. It actually locks on to satellites really fast even indoors.

I will be moving tomorrow and check it in actual road conditions with other apps, but my understanding is that installing ZUI seems to be having solved the issue.

I have not rooted my phone, so I cannot further adjust the gps.conf file. But I guess it will make things even better.

In the official LOS14.1 It is not supported....
[Zuk Z1 Original Android Development] strange76:
Hi ,

Feedback, I have just switched from Unofficial LineageOS 14.1 to official LineageOS 14.1 (7.1.2 with android security level of May 5, 2017)

Everything works fine for me. (Only one sim).
[Zuk Z1 Original Android Development] axolotl98:
So a bit of a 2nd update on the issue.

I have verified that the GPS functions normally now. It might not be the fastest sat acquisition and lock that I have seen in a mobile phone, but it is good enough for the mean user. And there is always the chance to further fine tune it following the guide offered above.

However it is not all sweet pie. My phone started burning up more juice than before. For some time now I am using an amazing app named Accubattery to understand the battery consumption of my mobile phones. For ZUK with the official LOS it was at about 20 mA with no apps running in the background and the screen off.

After flashing the ZUI and going back to LOS again, the amperage has climbed to about 50 mA, reducing the autonomy of the ZUK.

Has anyone seen this as well? Is there a quick fix on this issue?

Thanks for letting me know
[Zuk Z1 Original Android Development] wackou:
And what about molotov or mycanal ? Doesn't work ?
[Zuk Z1 Original Android Development] strange76:

[Zuk Z1 Original Android Development] TrojanPL:
I performed TWRP backup, installed ZUI v2.5.358ST, booted phone to ZUI, rebooted to recovery, restored TWRP backup and I still have massive problems with getting GPS fix.

I have also restored my TWRP backup with Marshmallow CyanogenMod and GPS works normally - fixes quickly.

Fingerprint NOT working

I need help to fix my fingerprint sensor.

installed the Lineage OS 14.1 on my device after that expressed that the fingerprint scanner sensor is not working I tried several ways to fix it but I could not please help me if you can
[Zuk Z1 Original Android Development] themonsterit:
Mine uses 50 mA too when screen is off, phone cames to the end of the day with 50% battery as usual, exactly as cm13, i think you don't have to worry about it, maybe battery read scale has changed in the firmware...or maybe your phone was working with some uninitialized hardware and now all is working as expected.

thanks, so I just flash the unofficial before the official? do I need to boot or I can just flash then wipe then flash again in twrp before boot? same reason why mokee has error 7 too?

btw any problem with gps fix? reason I want to switch from ZUI 2.5 is the gps direction goes crazy and its much needed when on the road for direction,
[Zuk Z1 Original Android Development] danielbrik:
I needed to do this myself and it works fine now, no more error 7. What I did: backup with titanium, wipe data cache and calvik. Then I installed the unofficial wiped again (because why not) then installed the official without problems. All this was done without leaving the twrp recovery.

Bugreport: Camera crash on zoom

Error:

Camera app freezes when zooming while making a video

Version:

Android 7.1.2

ZUK Z1

LineageOS 14.1-20170516-NIGHTLY-ham

Steps to reproduce:

1. Open camera app

2. Start recording video

3. Zoom into the video with the two-finger gesture

4. app becomes unresponsive, timer stops counting and after a while Android wants to kill the process

logcat output:

Further comments:

After the camera has crashed once I cannot restart the app (it immediately crashes)

The only thing that works is completely rebooting the system

I have this problem since I started using this ROM (So practically since the first official LineageOS version), so its definitely not new

Hello,

I think the best way to report this issue is to create a jira ticket (https://jira.lineageos.org) and put all your information will be enought.

But actually, I don't know why, but [MENTION=5426059]ashwin007[/MENTION] doesn't seems to be active since 3 months :(
[Zuk Z1 Original Android Development] tanmeshn:
This is a very good ROM, only problem is heating. Sometimes Even while browsing phone heats up. Also If I play games like COC , phone overheats and metal edge's heats up real fast. I got small yellowish-orange patch on top left side of the screen, I don't know if its burn-in mark or whatever since IPS LCD doesn't get burn-ins on screen. If I take screenshots it doesn't show up on that, otherwise I would have shared screenshots.
[Zuk Z1 Original Android Development] krishnamn:
Supposed to be best clean rom for zuk z1.but very less support and random rboot and camera freeze bugs not resolved since the built.
[Zuk Z1 Original Android Development] Srlobo_2:
I do not think it's a problem with the rom, I've never had temperature problems.

Neither reboot problems nor freeze the camera now. I think you should try a clean installation.

Well I just tried the video recording (I barely use it) and you're right, it freezes after a while recording to 1080. Zoom works. What I can assure is that random reboot I have never had.

Guys,

I have a problem with Error 7 during installation of the newest build from 16.05.2017. I could update the previous builds without problems but recently I have installed ZUI over LOS to fix GPS (which did not work), restored TWRP backup with LOS and since then I cannot install:

- latest CM13 (18.12.2016)

- latest unofficial LOS (30.01.2017)

- latest official LOS (16.05.2017)

Each installation ends up with Error 7. I use 3.1.0.0 TWRP. What can I do?
[Zuk Z1 Original Android Development] DON2003:
even unofficial also error 7?

may I ask if you have any rom that good on gps navigation? or remember which marshmallow works best gps fix?
[Zuk Z1 Original Android Development] TrojanPL:
Yes, that is correct.

CM13 and COS12.1 had very good GPS.
[Zuk Z1 Original Android Development] DON2003:
so no more LOS after going back to CM13?

can I just flash CM13 over Nuclearom which is I think LOS 14 base?

need the gps, google maps and waze on trip,

thanks

btw cant find CM13, can anyone share link for CM13 for Z1?
[Zuk Z1 Original Android Development] Aris_Toteles:
This might work:

Wipe everything, exit TWPR, boot TWPR, install latest unofficial LOS again
[Zuk Z1 Original Android Development] axolotl98:
Exactly the same issue here. I guess it is due to the ZUI update (which by the way worked for me and my GPS now works OK) and I need to wipe it clean and install the latest nightly. However I have more than a 100 apps installed and just setting them up would be a nightmare. Hence I am delaying it...
[Zuk Z1 Original Android Development] TrojanPL:
Same situation here. I do not want to wipe my phone.

The worst thing is that my GPS still needs a few minutes to fix and looses fix very easily.
[Zuk Z1 Original Android Development] :
Advice..

Please use nuclear 3.0

Best marshmallow rom in my opinion.

Rock stable.. Cm base.. With some extra essential features baked in.

Btw.. I don't have link of Cm13, so wont be able to help on that.
[Zuk Z1 Original Android Development] DON2003:
but does the gps works fine on nuclearom 3.0? bec am currently on nuclearom 2.0.5 nougat & gps works intermediately,

can I just wipe and flash nuclearom marshmallow directly from nuclearom nougat?
[Zuk Z1 Original Android Development] :
Gps wprks fine.

I am sorry but as far as I know ypu would have to do a clean flash. (nuclear 3.0 is marshmallow whereas 2.0.5 is nougat)

You can use titanium Backup for setting up apps though.( nuclear 3.0 is prerooted - you just need to enable root access in developer settings).
[Zuk Z1 Original Android Development] DON2003:
may I ask if clean flash means wipe all except internal storage then install rom then wipe dalvik again? so flashing marshmallow over nougat just simple as change to other custom rom and no any extra steps needed?
[Zuk Z1 Original Android Development] :
Yes.. Wipe all except internal and usb otg.

Also.. Gapps needed will be of android 6.0.

And yes its same as flashing other custom rom.
[Zuk Z1 Original Android Development] DON2003:
is this the one? [ROM/KERNEL] NucleaRom [Android 6.0.1_r74] + Radioactive Reborn Kernel

so for gps, marshmallow rom works but not any nougat rom including LOS?

or kindly point me to nuclearom 3.0 if that’s not the 1, thanks again
[Zuk Z1 Original Android Development] :
Yes. Thats the one.

I haven't tried gps yet on nougat roms. (don't have any app that requires precise gps location), but have heard about gps non functionality of nougat roms. (as far as i know, gps in zui works fine)
[Zuk Z1 Original Android Development] SimJoSt:
Thanks. That did it for me. Not an issue anymore.

How come this works? What does the unofficial rom do, that the official one can't?
[Zuk Z1 Original Android Development] jaboneros:
latest 0516 still same bug as 0502, am on 2 sims, with sim 1 set to data, calls and sms, and without warning data, calls and sms switches to sim 2.

as with previous installs, did factory reset before flashing zips
[Zuk Z1 Original Android Development] @jerrrielll:
I'mactually using Mokee rom the last release they had on marshmallow it includes all of the updates for marshmallow most stable for me and it includes aegis so you can hibernate and disable wakelocks +gps works fine
[Zuk Z1 Original Android Development] jaboneros:
no issues on dual sims?
[Zuk Z1 Original Android Development] @jerrrielll:
Yes im using both sims and both working fine
[Zuk Z1 Original Android Development] TrojanPL:
You can clearly see that there is massive other-ROM-off-topic here because official LOS is so buggy... Is there anyone working on it right now?
[Zuk Z1 Original Android Development] wackou:
Actually, a little bit ...

Last change on lineageos code review is related to the trustzone and switch from gello to jelly (browser).

Also their is many open ticket assigned without any followup.

As mentionned, the maintener has board exams and is busy in his personal life (https://xdaforums.com/showpost.php?p=71931532&postcount=308)

So I think we will have to wait, we can update our lineageos, but we will get only change from lineageos and not to our device (since their is no change)

Search for "error 7"
[Zuk Z1 Original Android Development] TrojanPL:
No, it has not been answered yet. After flashing ZUI over official LOS, you get error 7 when installing CM13, ZUI, official LOS as well as unofficial LOS. No solution so far (besides wipe but no certainty that it helps).
[Zuk Z1 Original Android Development] Aris_Toteles:
If unofficial LOS fails to solve error 7 on first attempt, you have to exit TWPR and reboot back to TWPR. Then wipe system, (data,) cache, dalvik and install unofficial LOS again. Wiping /data/ 'might' not be necessary, but do it just in case or repeat, if something is still not working.
