Hi,
I have read the comments in amazon and also seen the reviews of Lenovo ZUK Z1 indian unit.
i found there are some issues like :-
-near the home button right side led light is not working properly.
-there are some heating issues in normal usage also.
-it hangs when we are in a call and there is only one way i.e. reboot of device.
-i also found comments saying that there is much difference between indian unit and other unit.
According to specs the hardware is realy good in this price segment but still some comments are saying its not worth to buy it.
Can anyone suggests wether i should go for Lenovo ZUK z1 (indian unit) or not.
I'm fairly happy with my ZUK Z1! I myself dide any of the issues you described, though I did have a major battery issue which I had to get fixed. Much more detail below;
The capacitive buttons' LED lights are just small white dots - they are a bit dim and hard to see outside (I believe that's just the way they are on the device). Regardless they do work fine - though I personally prefer on-screen buttons (navbar), which is an awesome option on Cyanogen which I do use (together with the physical home button). Phone does not feel hot to me (compared to other Android I tried - such as Sony Xperia Z3 Compact and LG G4 which did get confidently hotter). Calls work fine. I have no experience at all with the Indian version, I just had the International version with Cyanogen OS.
Now the problem I did have was that the battery my device came with was screwed up. The phone would turn off at random times and often display inaccurate battery percentages (e.g. fluctuating percentages, or phone displaying 1% for hours). It was really bad, a serious fault. Thankfully I was able to get it fixed for free thru warranty - since I bought it from a local store with 1 year warranty coverage (which was extremely useful for once). They replaced my battery for free and now it works great!
So that being said - there is indeed always a risk of getting a device with a hardware fault. Budget devices like this may be more prone to QA issues but remember that devices of any type or price occasionally have unit faults like that. Also keep in mind that people who have these issues are more likely to shout online than people who don't.
Overall though - I am quite happy with this device. It is fast and snappy, the battery life is indeed very good (lasts me a day and a half of fairly heavy usage) and I also like the fingerprint sensor (though I've had some mixed results with it. My tip is to make sure you initially scan your finger as best and fully as you can). I like the stock+ Android feel with Cyanogen OS (though Cyanogen are taking their sweet time with the Marshmallow update for this device! Though there are good custom ROMs for this device including CM13). I can recommend it.
If you can get it with warranty I say it's really a good choice, especially as a decent warranty can remove your worries. If I'd consider another device it would Xiamoi Redmi 3 Note Pro, which has similar specs but with a newer, better more efficient Snapdragon chip. There is also the ZUK Z2, but I think it's a shame that it has a smaller battery.
It's a decent phone but I wouldn't recommend it. A lot of people have problems with the home button (mine included) the fingerprint scanner doesn't work anymore. Cos has some nice features but the security patch is from last month and still no word on when we receive marshmallow.
My 2 cents, do yourself a favor, forget this phone unless it's free or very good bargain, it was promising at the start, end up as nightmare for most owners, just read some of the thread, every components has some issues, sound, GPS, home bottom, screen, battery, charging, COs patches, you name it.
Yeah, this phone turned out to be a huge disappointment. I faced issues with the original unit as well as the replacement unit. Eventually, I returned it and got myself a refund.
1. Back button led is dimmer than the menu button led. This is really annoying if you're used to the capacitive buttons. Even though it's a mid-range phone, this is not something that I'd expect because Rs.13,500 is still a good amount of money.
2. The phone has very obvious heating issues, especially near the top. Even when idle, temps refused to drop below 37-38 degrees. While charging, it was easily crossing the 50 degree mark. While running apps, it was crossing 60 degrees. My first unit became warm in my pocket for no reason at all.
3. The replacement unit that I received had vibration issues. The vibration kept turning off randomly. It used to turn back on after a few seconds.
4. Adaptive brightness is very slow. It takes a good 3-4 seconds for the ambient sensor to recognize the change in light intensity. I turned it off immediately.
5. Double tap to wake stops working after some time and you have to soft reboot the phone to get it to work again. However, I did not face this issue with the replacement unit.
6. The fingerprint sensor is not really as accurate and fast as the company claims it to be. The fact that you have to press the home button to wake the phone first adds to the time taken to unlock the phone. The fact that the home button isn't exactly soft does not help. More often than not, I had to keep my finger placed on the home button even after waking the device just to get it to recognize my fingerprint.
7. This one's a minor con but the ZUK printed below Lenovo on the back was slanted and not aligned perfectly below Lenovo. The print also appeared cheap and looked like it will come off pretty easily.
Considering the OPO has pretty much the same specs, I don't understand why the ZUK Z1 is plagued with so many issues. Also, in all the online reviews, the international version of the phone didn't seem to have all the above issues. Kinda makes me wonder if Lenovo has cut corners for the Indian launch of the phone, hence, the lower than the international version pricing.
Honestly, at this point, there's not much point in buying this phone. There are better and cheaper options available. Not to mention, some great phones will be coming out in the next couple of months, so it'd be better if you're willing to wait.

Mine is also showing up as a xperia z 1
very happy with this phone. after a day's work, i still have about 50% of juice. I've had xiaomi, LG, Xperia in the past. this phone just rocks.
using zuk z1
wouldnt recommend. breaking home button and missing software support and updates ... if my homebutton is broken i will swap it at amazon und buy another phone.
anybody solved the problem of failed recognition (zuk z1 = sony xperia z1). is it possible that that is the reason for google play store some apps show me that my device is not supported?
I've been the owner of 2 ZUK Z1 during 1 month, running Cyanogen 12. Problems with Network connection, GPS and hands free through Bluetooth. since I usemy phone with dual Sim for work&personal, I need it working 100%. Because of those issues, I flashed CM13 ( not working after flashing gapps) and finally resurrection Remix ROM. It didn't solve the Bluetooth problem and battery drains quite fast and phone is too warm. I even flashed last update (June 18th) but heat and battery problem still the same(only solved rooting use with June 16th version)
I came from a Jiayu S3 and I've just confirmed I didn't take a good decision buying those ZUK Z1. I'll have to look for aHuawei or Xiaomi mobile phone or is anybody happy with ZUK Z1? running which ROM?
Thank you for your help
If a rom isn't working for you it's not directly the Roms fault... I believe it's yours
Using nuclear and I'm totally happy. But none of those cm13 based Roms will fulfill your needs because dual sim functionality isn't fully implemented.
I have never had any of those problems in 6 months of using my ZUK, maybe you just got a bad one. Did you try contacting your seller for replacement?
I have mine since October and so far it works pretty well. I have a sot of 5 hours and still have enough energy left to easily reach the end of the day. GPS works fine for me I use it every week. No overheating issues so far although the phone can get really hot if the sun shines directly on it for a longer period but no problems when I use it or when it's in my pocket.
The only things that I dislike is the wide of the phone it's just to big for me (I have small hands). The camera is not that great with low light conditions, and still no marshmallow update, that's it
Love it despite its weaknesses
I ordered my Zuk Z1 back in October 2015. I use my phone with a professional sim in addition to my personal one which handles the 4G connection (note: both sim cards cannot offer data/4G). I have been running CyanogenOS exclusively because of Good Technology (incompatible with rooted devices). I do not concur with your opinion: COS 12.1-YOG4PAS9IG is rather mature. The network connectivity issues you are facing may be due to the lack of LTE band 20 (800MHz) support. I do not face any severe issues. I would certainly appreciate if it switched from 3G+ back to 4G faster than it does. WiFi 2.4 and 5.0Ghz perfectly work without any drop. GPS does work too, though it may take time to synchronize on rare instances. Bluetooth audio (streaming music to headphones, speakers) works perfectly although I cannot comment for the hand-free function (microphone) which I refuse to use for safety reasons. Battery runtimes are really great if you are not maxing out the brightness level. In my experience, battery drains are not linked with COS but third-party apps. I did not identify any heating issues : temperature is reasonable. Software support is great (about one update every two months) although people complain about COS13/Marshmallow being unavailable (June 2016). Annoying bugs (e.g. broken screen rotation) have been phased out quite quickly. I am really happy with this phone.
Good: nice runtimes (a full day) thank to the 4100mAh battery, the SD801 CPU is fast enough for my use, 3gb of RAM and 64gb storage are generous enough, decent 1080p screen but not best in class (compared with Amoled or Sony Triluminos), CyanogenOS is rather nice compared with stock 5.1.1
Bad: camera is mediocre, hardware button are not properly located and cannot be reversed (I disabled them by enabling the on-screen navigation bar), the fingertip reader sometimes fails to recognize your tips (fairly rare but worth mentioning), no sdcard reader.
Ugly: lack of LTE band 20 (800MHz) support
I'm trying again with my Z1. After original COS (GPS and Bluetooth issue), I tryed last Resurrection ROM (overheating and battery drain), I'm trying Cyanogrnmod. I had some issues with it when flashing Google apps (ARM - 6.0 - nano) and I got continuously error messages from google apps. I did wipe data/Dalvik after installing ROM and GApps but I always got this problem. I flashed everything again and it finally worked ( I don't know if anybody else is experiencing the same). Now running CM13 I will need a few days to evaluate it. For the time being no Overheating/battery drain problem at all. I still have to check deeply GPS/Bluetooth and rest of things. It seems it works properly...
If it fails finally (I hope not...) I will try nuclear ROM as adviced by some colleagues.
I'll keep you posted.
Thank you for your support
You need to understand that battery drain is caused by 3rd apps. Install PowerPRO and set home/work/outside modes. When i don't play any game then my zuk keeps alive for 2-3 days easy

Just flash gapps immediately after cm13 before restarting
Does cm13 have double tap to wake??
No. It's there in the settings. But it doesn't work
does aroma gapps work with cm13 snapshot?
download Naptime from app store
nuclear rom is pretty nice and battery friendly
Hey folks, I am Canadian that is looking to possibly import an MI5 but I figured I should find out a few things from you all that have been living with these phones for a while before buying.
Are there any hardware or software issues with the MI5 that I should be concerned about? I have a sony z3 compact right now and it's been infamous for vibration motors, headphone jacks, and screen failures. It also has no AOSP based daily drivers.
Development seems to be pretty active here, is that actually true? Are developers dropping off from this phone or is there still a steady amount of work being done?
From the lurking I've done it seems that unlocking, rooting and ROM installing is pretty easy. Are there any permanent dangers to doing these hacks (above and beyond the usual)?
I'm aware there is some camera quality issues on non-stock ROMs, is the camera still usable? How is the battery on custom ROMs?
Is there anything preventing this phone from being a daily driver when using a custom ROM like RR? Does the fingerprint sensor work on AOSP ROMs?
I am also aware of the radio bands the MI5 supports, I should be fine with that as my imported Z3 Compact has the same bands (as far as I can tell).
Edit: I was also wondering if the IR blaster works on custom ROMs!
Thanks for reading, answering and putting up with my ignorance. I'm just looking for some answers I couldn't find on this forum when I was searching yesterday.
Community is happy to help
1. Hardware wise you have to keep in mind the phone is fairly fragile. Low light performance of the camera is a bit poor. Audio out of the headphone jack isn't great on stock MIUI, but that can be fixed with Viper4Arise or any AOSP ROM. RAM management and general performance on MIUI is "ok" - but the phone is blazing fast on AOSP + CAF. There is no component that is prone to fail that I am aware of, but I have read of the occasional hard-brick triggered from nothing more than a reboot on custom ROMs - this can be solved by flashing stock ROM in EDL mode.
2. There seems to be a steady amount of development going on - we just got the drop on about 7 new ROMs in the last month. However, there are and have been developers leaving in favour of the One Plus 3, and development is only moderate compared to its forum.
3. It's fairly easy, but a bit frustrating getting the bootloader unlock from Xiaomi, as it usually takes about 5 days for the unlock to be approved and then 5 more days for it to actually work. There is also a possible driver issue on Windows which can prevent unlocking, so if you're stuck that's probably the case. Except for the above mentioned possible hard-brick there are no additional dangers, and dare I say less so than other phones I worked on.
4. The camera is usable on custom ROMs but considerably worse. Mainly there is a lot more noise in the photos, but detail remains high. Video recording seems to be broken on most AOSP ROMs, but alternative camera apps are apparently a work around. In my experience battery life is better on custom ROMs as they have functional Doze on Nougat, but not by much.
5. Fingerprint sensor works fine on custom ROMs, even better if you consider that you can wake + unlock your phone without pressing the button. There have been reports of some people experiencing slow fingerprint scanning on custom ROMs (3-4s). I use a custom ROM as my DD and I don't have any major issues except video recording that I haven't yet bothered to address.
I hope that this information finds you well. The Mi5 isn't perfect, but I'd be damned to say that a better phone exists for $200. The camera, battery life, performance, screen, audio, and design is good and there really isn't much to worry about.

Thank you so much for the detailed response! Greatly appreciated!
This all is reminding me of the fun I had with AOSP ROMs back on my Galaxy SIII, happy thoughts! (I've been stuck in Sony's software for too long!)
What is CAF?
Is the IR blaster working in AOSP-based ROMs?

It's a pleasure
Well then it's good to know they run brilliantly on the Mi5 (buttery smooth UI, and I get good numbers on benchmarks as testament, see attached pics).
CAF is short for Code Aurora Forums, a collection of companies that merge their updated driver code with the vanilla AOSP code from Google.
I don't know if the IR blaster works on AOSP as I currently don't have any devices on me to test it with. I could try this weekend when I get home.
Edit: I've since arrived home and can confirm the IR blaster works on AOSP. I used Anymote if you're interested.
Hi Guys,
Does anyone has a lag/stutter while playing PUBG?
Tried all the seetings but the stuttering is really annoying.
I have this issue too. Why does snapdragon 855 lags on pubg mobile. There is serious frame drop issue. Xiaomi please fix this.
What setting are you playing on? Because for playing too long in hdr with extreme fps might be making this lag...
i didnt have any fps issue on highest setting , only the back of the phone getting hots.
Back of the phone gets hot with even smooth extreme setting
My k20 pro lags even with smooth extreme settings. Will a software update fix this??
Facing the same issue
I am facing the same issue in K20 pro. extreme frame drops. Even if you select low fps it will lag.
Pubg lags/stutter is present in all custom roms... Even in all stock/eu roms too. For me the performance i got in latest chaina stable. It also lags/stutters here n there but much better performance than the custom roms
Have you tried disabling all the touch response and sensitivity stuff in the game booster which is accessible through the security app?
For me the experience is much smoother after I've disabled all those additional features
K20 pro pubg problem
I also get major lag in pubg with smooth extreme setting how sd 855 can't handle smooth extreme in pubg & it has touch issue to will they fix this with a update
I'm playing HDR + Extreme and stable 60FPS whole game...
ermmm remember to let your phone cool down , smooth extreme is actually a 60 fps , its high demand , of course there will be thermal throttle , benchmark test also slow down when phone is hot
Zero lags here on 6GB version. Smooth/HDR both at60fps run buttersmooth.
There is render lag and framedrop when squads come nearby taking it from 60 to 45fps but it's a server related part and happens on all including OP7Pro.
Do hibernate all social media or background persistant apps like FB, WHATSAPP, TikTOK, Messenger, Instagram etc by using Greenify and use dehibernate after you're done playing so none will consume cpu/ram or introduce spikes in ping by trying to pull notifications/updates in background.
beacuase of miui 11 bugs. dont update your k20 pro to miui 11.

Maybe not be the reason for the recent lagging issue, but I do believe this holds some water.
MIUI 10 was a better performer. Wish Xiaomi released less phones and focused more on software.

Totally agree!!
Tested PUBG on both MIUI 10 and 11. Despite of more device heating with MIUI 10, pubg performance isn't too bad. Infact I found the sweet spot when I disabled the game booster with display overclocked to 81hz.
I tried many different settings on MIUI 11. No luck yet. Frame rate keeps dropping below 40fps.
I have same issue with note 10 SD 855 and it's ****in irritating af.. If I factory reset it'll play fine for maximum one day then lag will come again
For anyone facing lag &framedrops - if you're rooted on miui install Franco kernel manager & then under miscellaneous settings select thermal profile "not set" out of the 10 or 12 available ones.
Experience smoothest gameplay after this [email protected], even [email protected] without random slowdowns or microstutters. (Except when nearing other squads as it's a server side lag issue)
Also do check under the Guides section for my post on this.
there are news about Miui 13's bugs ? (on Redmi Note 10 Pro)
Have Redmi note 10 pro stuck on Miui 12.5, but i think flash it in Miui 13.
I wanted to know what bugs are left in Miui 13, and what is gained (or lost).
Because apparently Miui is known for its many bugs. (And even 12.5...)
In terms of overall performance, in games; what are the gains?
If there are benchmarks on big games like Genshin Impact between these two versions
Thanks in advance and sorry for the translator :/
-Flickering in apps such as discord and youtube
-Sometimes the notification panel when pulled down is completely transparent
Also some users have faced systemui error and camera brick after updating so be careful.
an old bug, that no one at Xiaomi tries to fix:
In SystemUI (latest Xiaomi.EU MIUI 13.0.12 and lower) are 2 methods of do not disturb (DND) integrated. at least DND can not be deactivated and activates itself by fault. that is annoying and a long known bug without fix or workaround.
Dual-SIM management doesnt work proper. Taking SIM-cards online /offline is buggy and works like try and error.
Found screenflickering in youtube and google app in low light conditions from time to time
But all in all, the jump from 12.5 to 13.0 is worth! dont postpone it much longer.

I will look for update it. And how do you feel about the overall performance ? do the games run better ?
The overall performance is better. Games run the same as before since a software update doesnt improve your hardware. Slight better since I used gamemode. Never have had hardware issues in PUBG or other FPS. Never tested Genshin or else. Sorry
The front camera just died and no sound is coming through Bluetooth devices after the update.You better not update it .

That has been happening lately and it can even happen on miui 12.5 or even aosp rom not guranteed that it won't thanks to xiaomi for that.
