Hi Guys! Been using this phone for almost a year.
1. Working good for the first 8 months with Cyanogen12.1
2. Last few months, noted overheating patterns and lagging and restarting issues.
3. However, performance and battery life was still good.
I guess the overheating and restarting problems are due to software issues.
So, what I did was look for many reviews and research for Good zuk z1 roms.
At first was like, I should update only to Official ZuK software. But boo, poor software support. So why should I wait for nothing?
Finally, I am so happy with my research. It worked for me! All the hard efforts were paid. I have the latest software with minimal tolerable bugs!
Maybe this can help you and appreciate this phone again:
1. Unlock your bootloader. (This requires a lot of patience to work)(videos in youtube helps: use keywords:unlock bootloader zuk z1)
2. Install custom recovery with TWRP
3. Root your phone. With super su
4. Download CM13(marshmallow official)-CM14(nougat 7.0 official)-Lineage14.1(nougat 7.1.1 by ordenkriegger) roms. Download them all for they are incremental updates and you cannot directly install nougat from lollipop.
5. Download Gapps ( download each for marshmallow, nougat 7.0 and 7.1)
6. Then were all set.
7. Go to developer options and allow advanced reboot-> recovery
8. Do a wipe first, then follow this installation pattern:
Flash with cm13 first then gapps for marshmallow then reboot.
Go to advanced reboot-> recovery
Do a wipe-> flash cm 14->gapps for nougat then reboot
Advanced reboot-> recovery
Do a wipe-> flash lineage 14.1-> gapps for 7.1.1 then reboot
You have the latest firmware for lenovo zuk z1!
Fingerprint sensor is working properly
Camera support and 4k video support is very good.
No Volte as the official ordenkriegger page said.
So far, restarting issues were not present on my experience.
Fast and split screen support
Increased antutu scores
So far, some minimal issues with stock brower which lags but may be overcome by downloading google chrome. And use chrome as default browser.
The unlocking of bootloader itself is a pain in the ass. I was stuck here for almost a day. Just do your reading and research. Everything will go well.
So now, I'm happy again with my Zuk Z1. I' m like having a new phone again!
Just be patient.
I am John Wickk.

Worst phone you can ever come across. My Lenovo Zuk 1 developed issues within the first month of using it and d worst part is, the service is horrible. The service center people are extremely uncooperative & arrogant.
Don't ever buy any Lenovo phone.
AnonD-650131, 05 Mar 2017Don't ever buy this phone service center so poor.I trust service instead giving it to outside ... moreI Agree your words. I really faced same situation in Hyderabad in India .The service was very very bad . You will go to service centre for any minor problem ,they will say it is not possible and escape easily.I will recommend not to buy this phone and another problem with this phone is device is getting heated at the time of charging and talking .
Home button is not working finger print season is not working frustated
Don't ever buy this phone service center so poor.I trust service instead giving it to outside for repairing but it is 5th time i will go to service.furthermore they also replace your parts of phone for example I don't have any problem With camera they put some defective part of other phone now my camera is foggy .
Heating,hanging,mic,camera problem etc. So guy don't ever buy zuk either any lenovo phone.
