Yes it has the blue screen bug, sometimes it happens, back in the thread you can easily check.

Not always, but happens.

Aug 7 build with clean flash.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Never had it since the first release. Could you describe it?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] -totonio-:
Yes, when unlocking the phone with the power button, sometimes the screen turns on and it stills with a blue screen, displaying nothing, you need to press power button multiple times until the system UI is displayed (I have CRT power off animation, so I can clearly see that the display turns off)

When trying to unlock directly with the fingerprint, I feel the "unlocked vibration" but the screen stills blue, and I need to do the same thing with the power button described earlier.

It seems like the phone makes a huge effort to display the system UI.

It happens after, I guess, 30 mins of deepsleep and also when I lock and unlock the phone in 2 minutes, totally random , but it happens.

I can add, that in those moments I feel the phone very hot, but it's hot outside, so I can't prove the relationship with this.

Oh, and this is the first release that has this problem (to me)

Thank you!

Please provide your inputs :) Thank you :)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
I set KA to disable dt2w + 'apply on boot' and rebooted: the phone started normally, KA applied settings and everything worked fine. I also turned the screen off and let the phone sleep for a few minutes; then unlocked it: touch works fine and dt2w is disabled.

Make sure touch boost is disabled (in KA).

Edit: rebooted again - everything worked as expected.

Use included Matlog app for logcat. It will sure show something, especially, if the phone is heating. But I bet this has to do with a third party Launcher you are using.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
As I said in the previous post: this could be related to a third party launcher you are using....
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] rocky459:
Pre-Requisite

1. DT2W disabled via KA.

2. Apply on Boot for the same.

Sequence to test:

1. Reboot the device(don't unlock it for 3-4 minutes)

2. The device needs to be unlocked only post KA has applied the settings.( So 3-4 mins should be good enough for safer side)

3. Now, if we try to unlock/touch the screen, nothing happens, so only option is to reboot via Power button.

Let me know, if you are able to reproduce via these steps.

Thank you in advance :)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:

I'm totally after QC3.0 despite the ROM. Currently, pretty happy with AOSP AEX 5.7. So I'm trying to avoid other ROMs within this segment. I have heard from other posts claiming Jaguar supports QC3.0; Now that would be awesome. So does it support QC3.0?? If not, then why does changing Kernel not help at all?

[MENTION=5075064]optimumpro[/MENTION], yes we have been already following this work around for few days now. Have also delayed KA application on boot to provide sufficient time to unlock. But the request is if you can find the root cause and remove this bug if possible.

2: And please remove these options in jaguar features /Buttons as they r useless: Force disable dardware keys , button backlight ,recents style and plz add more options to the navbar keys like AeX ,it has atleast 15-20 option there .

3: plz move that jaguar features to system ui tuner (it would get organised there ) and all stuff in jaguar features need to be recatagorised.

This is possibly my last post on this thread. My phone is gone, and there is some permanent damage on the board that is not repairable. The only way to get it to work is to replace the board, which costs more than the phone itself. It was 10 days out of warranty, and it just wont get 3g or 4g signal. All of this happened because I was charging at 9v at 2 amp. So I recommend anyone not to charge at 9v. The chatge times are off by only 15 percent and its just not worth risking your device. I have had to buy another phone now, asus zenphone max pro m1 with sd636 and return the z2 for about 3000 rs in that condition on flipkart which for a broken phone was a good price. Curiosity killed the cat this time I guess. :rolleyes:

Oh man. By the way what was you use I mean heavy use or a little. May be due to a lot of gaming the chip gets heated so it can cause many problem. And do suggest how to avoid such things
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] aliqadir37:
My usage was minimal. Only facebook, whatsapp insta n productivity. No gaming at all. I charged most of the time on the same 9v 2a charger it cant be the charger since i used it simce day one. Battery temps were also within safe margin, under 40 degree. It was just the 9v current that killed the lte modem on the board. Just avoid charging at 9v. 5v is safe, doesnt damage anytging, also doesnt heat up the phone. Stick with 5v everyone.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Don't listen to anyone telling you it is 9v. No hardware element, except for battery and battery circuit gets voltage/current from charger. The phone works from battery only. So, it is physically impossible to burn lte modem through external outlets.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] kunal sasane:
...

And above all on the battery it is written clearly that limited charge volt is 4.4. So I don't think 9v 2a was a good idea. And Qualcomm 3.0 right? I don't know but many say zuk z2 has Qualcomm 3.0. But again may be it was a marketing strategy.....just like when launching lenevo z5

---------- Post added at 03:18 PM ---------- Previous post was at 03:16 PM ----------

...

By the way I hit temperature upto 50 when gaming will it cause such things. I know that battery will degrade but it can be replaced other than that what are consequences?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] aliqadir37:
It happened in front of my eyes sir. I have eliminated every other software or hardware possibility that could have caused this except 9v charging. The board is wired to battery and charger cant feed the 9v to the board directly. I think charging at 9v since the beginning (one year) was having some effect on the battery which might have developed flaw overtime. It might have been a faulty battery or 9v. Neverthless i am certain 9v caused this, either by damaging battery or something else. Battery temps at 9v were always more than than 5v, it did some damage over-time.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Highly unlikely that a flaw in battery would burn lte modem. Any battery flaw won't raise voltage to hardware, and even if it did, hardware has it's own circuits, not to mention kernel regulation. You could simply have hardware failure.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
50 for CPU/GPU is fine. 50 for battery is high. Don't play pubg (or similar) on high settings. Apart from being a poorly optimized game, SD820 is simply not powerful enough for HD settings in pubg.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] kunal sasane:
Yeah. But only for pubg. Other games do work well ....and about temp what is maximum temp the chipset can Handel. And battery too ?,. .

Advance thanks
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] aliqadir37:
Yes, it was QC 3.0 definetly not a good idea, learned it the hard way. QC 3.0 with usb type c can push theoretical 12 through the port. This current and voltage is then adjusted on charge controller and then fed to the battery at a slightly higher voltage than battery output voltage. Normal usb can output only 5v. Even if it is at 12 v theoretical, it doesnt mean that battery is being charged at 12 volts. But it definetly heats up battery for sure, since more power is being fed through the port, 10 watt at 5v against 18 watt at 9v. Anything about 40 42 degree is not safe for battery longetivity. Cpu even gpu can easily handly 50 c. We ask too much of our devices which are basically passively cooled, by playing poorly optimised pc games on mobile arm architecture on our mere 3 to 5 watt tdp cpu, against 70 to 100 watt desktop counterpart which are actively cooled, liquid cooled maybe running x86. Gaming companies make tons more money through in game purchases and free distribution of games, instead of charging for them upfront like most pc games. Thats y games like fortnite and pub g are being offered to mobile platform, only to make money. Last thing they care about is out devices.

---------- Post added at 03:53 PM ---------- Previous post was at 03:51 PM ----------

Yes, a hardware failure is possible. Bad luck for me it happened a week after I ran out of warranty. :(
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] kunal sasane:
...

Well zuk did like about Qualcomm 3.0 charge and many lenevo service centre say we don't have any support for zuk z2. If by chance is it possible to change only the LTE chip or is it in main motherboard embedded?.....

About games like pubg and other. ..

We mobile user don't have to pay or purchase in game(depends on user I haven't done any purchase till now....)... So for pubg mobile it's very easy way to earn money....and about maintaining the game they don't do it they just add new maps, weapon team up and just cover it up by saying graphics are optimized ....

By the way I heard just to play pubg on pc we have to purchase the game for 1000RS is it true? And to play we need to have a highly expensive gaming PC. Yeah the graphics are jaw dropping (given that hardware is of top quality). ....

And above all pubg doesn't give a f*** about our device
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
If you look at QC2-3 certified charger, you will find that the output for 9v is not 2a, but 1.5a, which would give you 13.5WT, as opposed to 10WT or even 12WT on a regular charger (5v X 2.4a). Also, 2-2.5a is the maximum output, which is used rarely during charging. The same is with the current shown in custom roms: it is not the actual, but rather maximum current.

Also, I remember seeing hardware requirements for fortnite and pubg: only SD835 and 845 are recommended for highest settings. So, using SD820 on highest settings is a waste of hardware and battery.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] The.Night.King:
Op, since fortnite mentions a hardware requirements of minimum adreno 530 unlike pubg which works on a higher range of devices, do you think fortnite will be better optimized, because its got only a small list of devices to optimize their product for?

Although pubg runs smooth of HD & high FPS, which settings do you recommend?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] aliqadir37:
I sent it to a motorola/lenovo service centre for repair and they did accept it. They only said that its pointless to replace the motherboard since the device isnt in warranty and it would cost too much to replace. Yes the lte modem is embedded in the board so it is beyond repair.

Yes, we need to pay 1000 rs to buy pubg on pc then play. The in game purchase business model is very successful for companies than traditional business model of paying upfront for game. Its this business model that made mobile gaming about 10 times more profitable than traditional pc gaming. Pubg and fortnite are both owned by epic games. Both use the same business model of in game purchases for both pc and mobile gaming alike. With mobile gaming, its lot more accessible so a lot more profitable too. Keep your temperature in check. A 5 watt fanless mobile cpu is no match for a 50 watt desktop cpu for the same game.
