Lenovo ZUK Z2 Teardown
The ZUK Z2 smartphone was launched in April 2016. It has a 5-inch full HD (1920 x 1080) 2.5D curved LTPS display.
ZUK Z2 is powered by a quad-core Qualcomm Snapdragon 820 processor and comes with 4GB of RAM. The phone packs 64GB of internal storage, which cannot be expanded. The 13-megapixel ISOCELL camera is placed on the back of the phone, while you’ll find an 8-megapixel shooter (1.4um pixel size, f/2.0 aperture, 78.9-degree wide-angle lens) at the front.
The phone has a 3,500mAh battery and supports Qualcomm’s Quick Charge 3.0 Tech, which means you’ll be able to charge the battery rather quickly. The Type-C USB port is placed on the bottom of the phone, and so are its speaker and the 3.5mm headphone jack. ZUK Z2 has a metal frame and measures 141.65 x 68.88 x 8.45mm, while it weighs 149 grams.

Hello,
Thanks for the teardown! To replace the screen, is it necessary to disassemble the Z2 from the back, or can the screen be removed from the front? It would be awesome if you could give some instructions for screen replacement, as I can’t find anything on the web.
Thanks!
To replace the screen, you need to remove most parts from the phone.
Do you have a guide which explains how to replace the screen only?
Sorry! The ZUK Z2 has been out of our office for a long time.
Hi David,
Well, I took the plunge, bought a replacement screen (in the frame) from AliExpress, and fixed my phone. It seems to work perfectly! I couldn’t have done it without your teardown, so thanks again. The job took me about 2 hours and I’m pretty much new to this sort of work.
A couple of notes: first, my speaker module had 8 screws, not 5 as you reported. Maybe a different hardware revision? Second, I’d really recommend that anyone who wants to do this should buy the screen in the frame. It’s US$10 more, but it means you don’t have to muck around with removing the broken glass from the frame etc. The frame came with copper and graphite sheets and adhesive in the right places, so it was really convenient.
RobBrown,
Could you please share which display you bought? There are many sellers, but I really want to have the adhesive, etc., included.
Thanks!
Well, this is odd. In my previous comment, I included the URL where I bought my display, but it has been removed. I wonder if I broke some site rule by posting it.
So without posting any URLs, I got it from a vendor called “Mobile Good Helper.” The listing is called “For Lenovo ZUK Z2 LCD Display Touch Screen Digitizer Assembly With Frame Original Replacement Parts.” It’s US$55, and the manufacturer is called “Earchway” (which looks like “archway” because the ‘E’ is highly stylized and doesn’t look like part of the name).
One thing: it would probably be a good idea to contact them before buying and make sure that they have the thing in stock. I had to muck around with them a bit because they originally said they’d dispatched it when they didn’t even have it in stock. All up, it took about three weeks to get it.
RobBrownNZ,
Thanks, found it! I also scratched the frame on all corners so this one is perfect!
The glass is broken, but the digitizer is still functional. I ordered one and I will follow the teardown as soon as I receive the display.
M,
Good to hear. I didn’t have any real problems. The scariest part was getting the ribbon cable for the fingerprint sensor off. I protected the sensor itself with tin foil and heated the frame from the front, and it ended up coming off pretty easily.
Let us know how you get on!
Hi!
Is the front glass equal to the digitizer?
its possible to replace only the front glass? without changing the LCD?
or is it glued to the LCD?
Thanks
Replace the front glass is very hard, replacing the display assembly is ok.
I connected a pushing Beast 3.0 cable to an Aukey QuickCharge 3. Now, my ZUK can’t recharge. Do you have any idea how to fix that?
I’d like to ask once again about replacing only the touch panel. Is it possible without loca glue and a special UV lamp?
Thanks in advance.
BEST REGARDS
Martin
Thanks for the guide. I just have one question. I do not know how to remove the speaker. I am talking about the small silver rectangular thing that appears to be the back of the speaker. It is depicted in the picture below: “Here’s Lenovo ZUK Z2 chassis.”
The replacement screens at the usual shops do not seem to have this item, so I suppose it needs to be transferred. Do you have any ideas?
Hi, so I dropped my phone and it landed on the front. Now, there is no touch response in the middle of the screen. I think the digitizer is broken. I already ordered a new front panel with an LCD digitizer to replace this.
Also, the GPS stopped working shortly after. Now, I don’t get a lock on my GPS anymore. Should I replace the GPS/Wi-Fi board to fix this or is this a software issue?
Thank you so much!
Can I replace my broken Type-C port with a new Type-C port?
