[Zuk Z1 Original Android Development] :
I started to face the no-fingerprint-options-bug also (after trying various ROMs).

And I found that that for me, brought back the options menu... but I now found out that when trying to set a fingerprint, it doesn't set it.. it just wont notice any finger on the sensor.

Anyways .. why am I still messing around with various ROMs? Well... I found out even this one has random reboots.

Well... every ROM I tried seems to have .. And Im reading around on the internet, that this is is probably hardware related... So Im probably gonna throw my Z1 to the ground someday soon.
[Zuk Z1 Original Android Development] strongst:
Indeed it can be a hardware problem of the fp sensor as you can see on the z1 forum here. But if you won't flash cm13 before cm14.1 when coming from cos 12.1 that's the first problem most people have.

The other possible solution is flashing zui before your desired custom rom.
[Zuk Z1 Original Android Development] Alexmastergu:
Ok i will try flashing [TWRP][ROOT]ZUI_v2.5.358ST[ENG][FINAL].zip and will share
[Zuk Z1 Original Android Development] :
Omg... I now had these problems:

-Fingerprint sensor not working

-Screen rotation didnt work

I installed this file from TWRP, and they both got fixed: https://www.androidfilehost.com/?fid=24351979186684091

( I found that link here: https://xdaforums.com/zuk-z1/orig-development/unofficial-cm13-t3277885 )

Thank you strongst !!

PS: Do you think this also fixes the random reboots?
[Zuk Z1 Original Android Development] Dhruvshelke588:
This didn't work for me.
[Zuk Z1 Original Android Development] strongst:
The mm firmware files did also the job, but not for everyone. Good if it helped you :good: the random reboots are mainly a problem of apps or rom itself. The mm firmware files are providing drivers.
[Zuk Z1 Original Android Development] :
Occasionally, i found my zuk z1 got hang. The screen doesn't response to touch. Everytime i have to reboot it.

There is rare fingerprint lag. Is there any solution to these two problem?.

Everything else works topnotch.
[Zuk Z1 Original Android Development] Loganw21:
That usually happens when u soft reboot... So next time perform a complete reboot or power off the phone and turn it on
[Zuk Z1 Original Android Development] :
In developer option settings, whenever i set backgrounds process limit to 4, after every weekly sordid flash its switch back to standard limit. Any relevant reason why it is happened ?
[Zuk Z1 Original Android Development] Loganw21:
Yea... That's supposed to happen since u r applying an update over previous ROM... This way u don't lose your data but you lose your standard settings
[Zuk Z1 Original Android Development] Sharma_Ji:
How many times i posted it, if you want your setting to not lose just like what happens in standard oem updates, use cyandelta app, easy to use, works like charm

Use cyandelta app... That should help
[Zuk Z1 Original Android Development] :
Zuk z1 official recovery is not compatible with cyandelta.

My phone might be in bootloop .
[Zuk Z1 Original Android Development] Sharma_Ji:
Who said about officail recovery, if u installed lineage os, u must have twrp recovery.:mad:
[Zuk Z1 Original Android Development] :
Twrp of course , does cyandelta app need root ?
[Zuk Z1 Original Android Development] Sharma_Ji:
Yup, to open recovery and do flashing automatically

Otherwise it will download that delta zip and you can always flash that manually:svetius:

Does Unofficial Multirom v33 + twrp 3.1.1 working fine with lineage os 14.1 ? Can anybody give a bit review about it?

It's there in last 2 builds too, it means by live display..
[Zuk Z1 Original Android Development] :
Above upcoming changelog link confirmed. There will be no ambient display tile in today's build because zuk z1 does not support ambient display.
[Zuk Z1 Original Android Development] Sharma_Ji:
See my screenshot, tapping it enables live display.
[Zuk Z1 Original Android Development] :
Live display is already available in display settings.
[Zuk Z1 Original Android Development] Sharma_Ji:
Yeah, because 2~3 builds back, this same commit was in website, and this came out.

Maybe same will happen today, who knows ?:confused:

Battery charging becomes slow in new build and phone is heating like a hell. I don't need any oreo update and I'm just waiting for snapshot ham build.

---------- Post added at 11:48 AM ---------- Previous post was at 11:46 AM ----------

I think nightlies are degrading the battery life of zuk z1.
[Zuk Z1 Original Android Development] strongst:
You should check for any process running in the background. You can use better battery stats. And also make sure you did a clean flash of the rom and your device temperature isn't too high for charging(use ampere app).
[Zuk Z1 Original Android Development] :
how to find heat causing app?
[Zuk Z1 Original Android Development] Sharma_Ji:
He's right, i am on lineage most of time from last 6~7 months and always finds quality increasing
[Zuk Z1 Original Android Development] strongst:
If you see process that needs cpu time and also there are apps that measure temperature of the battery.
[Zuk Z1 Original Android Development] :
Does better battery need root?

I am thinking that if i flash magisk stable, it might help in cyandelta app, since the newest version of recovery not available as well as in better battery stats.

Is it the right choice to root the device ?

---------- Post added at 02:14 PM ---------- Previous post was at 02:13 PM ----------

But lineage os guys , not in favor of root.

---------- Post added at 02:18 PM ---------- Previous post was at 02:14 PM ----------

Torch tile is not working. Can any body confirm it?
[Zuk Z1 Original Android Development] strongst:
Better battery stats needs root. Just use root of your choice.

Torch tile is not working.

It is working .No problem with that.

[Zuk Z1 Original Android Development] :
Do you flashed via cyandelta or manually the whole file?
[Zuk Z1 Original Android Development] strongst:
I already suggest you to make a clean installation instead of dirty flashing on top of the old rom https://xdaforums.com/zuk-z1/orig-d...oid-distribution-zuk-z1-t3569082/post73950491
[Zuk Z1 Original Android Development] :
I havent been clean flashed since 1st build , everything fine for me till yesterday but today I flashed ROM with cyandelta manually (no root) 40 mb file after that torch tile is not working. Is there any specific reason behind it?
[Zuk Z1 Original Android Development] Sharma_Ji:
I used cyan delta, its working
[Zuk Z1 Original Android Development] strongst:
Ok, that's really insane :D make a full backup of system, data, boot partition within twrp and clean flash the rom+Gapps(mini or smaller is recommended) and test if the torch tile is working or not.

One can predict that snapshot may come at the end of next month. Till snapshot , i will keep on doing sordid flash.;)

Did you face finger print sensor lag sometimes?
[Zuk Z1 Original Android Development] Sharma_Ji:
Its problem in our device's build or maybe others , i dont know

When an app creates overlay on lock screen like during calls or alarms, after that fingerprint stops for sometime.

There are other developers of other devices having fixed this, i found out the real issue when reading other devices development threads, u might want to look at it [MENTION=5426059]ashwin007[/MENTION]

Thank you for the ROM, successfully installed it but it is lacking many customization available in RR ROM, please add some of the basic features form other ROMs into it.
[Zuk Z1 Original Android Development] strongst:
If you want more features, use RR rom. Official LineageOS won't become more features like RR. The source is the same for all devices, like RR. So please be so kind and use another rom which fits your needs.
[Zuk Z1 Original Android Development] boris dmello:
I know that LOS14.1 cant have all the customization of RR ROM i am only suggesting basic features that are available in other ROMs like no need to hard press the home button to go home screen, option to switch off vibration when fingerprint is recognized, etc
[Zuk Z1 Original Android Development] Korvin Silver:
Is there a reason why Titanium Backup doesn't work with Lineage OS? I tried with the addonsu and with SuperSU, too, but it didn't help. After clean install it won't even start restoring anything, it stays at 0%. I used RR and many other Nougat ROMs before but never had problems with it. I was looking forward to an official LOS mostly because with RR WiFi disconnects all the time and I don't really trust MoKee but if I can't restore my apps from backup and I'd need to start everything from scratch with LOS...

So, anybody has an idea?

[Zuk Z1 Original Android Development] ziveca:
USB OTG (Sandisk)

Hi,

I have connected my Sandisk Ultra Dual Drive. The built in system app recognized it and all works fine, but when I try other third party file management app (also SanDisk Memory Zone) they do not recognize the USB drive. "File Manager +" returns a message that NTFS, exFAT,... is not supported.

With the unofficial version of LineageOS by OrdenKrieger all works fine.

Is possible to fix this? Thank you.
[Zuk Z1 Original Android Development] :
I currently have the COS (12.1). Do I need to flash CM13 first and then LineageOS 14.1 or could I flash it directly? I'm sorry but just wanted to ask..
[Zuk Z1 Original Android Development] guillelmo4:
You must to read de instructions.

Yes, you must flash cm-13 first and then flash lineage os. if you don´t do this, your fingerprint doesn´t work for example.
[Zuk Z1 Original Android Development] Shivver:
Everything is nice, except that screen responsiveness when writing on keyboard is pretty bad and the camera recording issue is still here.

Thanks for working on this ;)
[Zuk Z1 Original Android Development] Korvin Silver:
That helped, thanks.

Does encrypting the device works to anybody? It behaves the same as with every other Nougat ROM, after I try to encrypt it, it starts the process and reboots without doing anything immediately. I hoped LOS will make it happen. I wonder why this is, such an important feature should get high priority yet nobody seems to care.
[Zuk Z1 Original Android Development] derMerowinger:
The [MENTION=5027381]OrdenKrieger[/MENTION] ROM really worked for me except the built-in camera app which solved OpenCamera.

Unfortunately the official nightly kills the phone part.

When the SIM is in slot2 someone who calls gets the freeline signal but the phone does not ring.

Trying to make a call, just nothing happens when clicking to dial -> as well with an alternative phone app.

When put in slot1 the phone rings, when somebody calls but the phone app does not appear, so I cannot take the call.

When trying to make a call nothing happens as well.

Trying to install it the second time, again the way it is explained in the first thread there is just the same problem.

So I just have to go back to [MENTION=5027381]OrdenKrieger[/MENTION] 's ROM.

The question is where did I go wrong?
[Zuk Z1 Original Android Development] mangareds:
same here...At this stage unofficial ROM looks stable than official one.

SIM card problem haunted even in unofficial ROM for some people.

It's mainly because of baseband.

But it's solution is very simple before installing LOS 14.1 ROM, install ZUI 2.5 beta ROM & then clean install any Nougat ROM of your choice.

ZUI updates baseband radio, that solves SIM card problem.
[Zuk Z1 Original Android Development] guillelmo4:
I have a update that is the same that i have installed, is it a general bug?, o is only un muy device?

Use Magisk ( https://xdaforums.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445 ) with Universal SafetyNet fix ( https://xdaforums.com/showpost.php?p=73432221&postcount=1075 , use the "hotfix" link for Compatibility with newest Magisk)

If any one find fingerprint problem and not have been completed one year since buy . Then warranty is still present for them.. Go to lenevo service centre and ask for your problem.

Then its a hardware issue... You should take your device to Service center... If its under warranty, it will be changed for free... And dont forget to flash Stock ROM before going to SC
