Catastrophic overheating on any ROM - Lenovo Zuk Z2 Pro Questions & Answers

Hello everybody, I've got my z2 pro a few days ago and almost from the first day I'm experiencing overheating problem. It not depends on ROM or software but it just heating over and over. When I'm putting it asleep - it cools down, but when I'm starting to use it - it heats much, usual temperature of CPU is above 45°C. I don't know if it's a bug or a hardware issue but i can't get my money back next I've got this device from some guy on my local analog of eBay over post and now I'm asking you to help me to cool it down at least a bit. What I've already tried is underclocking, restoring to stock ZUI, editing thermal config and i think that's all. On stock it's a bit cooler but only on a few degrees, and when I'm starting to watch YouTube or just serfing web - it's starts to heat very quickly. Thanks for your attention and please, if somebody know some way to fix it - tell me! That would be awesome!:fingers-crossed:

I got a zuk z2 pro a couple of days ago and tried cosmicOS and now I'm on AEX 5.2. I got overheating on both ROMs. I haven't seen people talking about overheating in the threads about these ROMs, so I assume it's a problem with our devices, maybe? Have you solved your problem or you just got rid of your zuk?

The best way is to flash zui 1.9.104 by qfil . It lock your bootloader . Then update to 2.5.462 by ota . Unlock bootloader and flash the last firmware 3.5.259 and custom rom of your choice .

If it's not starting to overheat in the first day of usage of new ROM - then you just should find ROM without overheating, because in your case - it's software-related issue and nothing more. Mine was with bad thermointerface or smth like that... And now i'm not an owner of zuk anymore so i cant test any of available ROMs to check if it happens to me

[Q] to lolipop rom users

Hello guys,
I've been testing all lolipop roms that had listed everything as working. Such as crDroid, CandyRom, SlimLP. On every of those lolipop roms pretty much most of the important stuff worked. There were stuff like equalizer not working or too dim notification LED, but from time to time I got touchscreen freezes. I mean I could use phone for a couple hours and then the touchscreen would freeze really often, sometimes it froze for couple of seconds and that was it and sometimes it could last for 10 minutes. This is really annoying and unacceptable if developer says that the touchscreen works.
I ended up contacting crDroid developer - davidteri81 and he said that the touchscreen works fine for him. I asked in the thread and I got only a single response saying he doesn't have this issue, but the sensivity is too high.
I've tried like literally 4 lolipop roms on my Z1 and each one of them had those touchscreen freezes. I even ended up flashing liquidsmooth in which I didn't had this issue, or it just didnt had the chance to happen since most stuff doesn't work there and it isn't usable as a daily driver so I quickly got rid of it.
My question here is:
Do you get touchscreen freezes? Please reply only after minimum 24h of usage. If you don't have any touchscreen freezes on lolipop rom on the Z1 then please, tell me what Lolipop rom do you use as I couldn't find any that wouldn't have a buggy touchscreen.
Please tell me if it works for you without issues or do you also have this issue on the Z1 as I'm puzzled because it couldn't be just me since I did a full phone wipe, flashed the phone clean, even wiping internal memory, but it still happens and I cant find a way to use any Lolipop rom everyday on my Z1. The more replies I get, the better.
@olokos: I'm on CM12 official and use it now for many days. In this time I never faced any touch freezes on my Z1.
I've got some other "bugs" that confused me a bit and make some manual fixes like Wi-Fi MAC. But for me I can say that this ROM is really stable and I use it as my daily driver.

Same for me, although, the touch screen did freeze once, but I locked it and unlocked it and it worked again. It's probably hardware since I got my Z1 replaced because of this issue that even happened on stock ROM occasionally.
using CandyRom 5.0.2
I never faced any touch freezes issue
@olokos: I'm on 20150214 and now I've got touchscreen freezes. This is the first time for me on Z1.
But I think that this could be a global Cm12 issue, because my Nexus 7 also get some freezes and I thought that something is wrong with my fingers or tempered glass.
The problem is how to debug this?
im on candy 5 and my screen dont freeze, but my screen percieves touches from nowhere... but only if i have earphone plugged in .. thats more than just annoying
anyone has the same prob?
sry for my really bad english
Touchscreen freezing issue definitely isn't hardware issue on custom roms. I haven't tried CM12 or any other apart from those listed on XDA, but I will propably build some lolipop rom from source by myself if I get enough reports that will be useful for me. If touchscreen works for you then please, tell me what rom you are using and for how long you use it, what't the way you flashed it.
I only need those 3 things. If touchscreen doesn't work just for me then I'll build my own stock based rom based on Sony sources. I just have to make sure that the touchscreen issue isn't just on my side.
All I need is:
Do you have touchscreen issues? Yes/no
What ROM/Kernel you are using? CandyRom 5.0
For how long? 5 weeks
Answer those 3 questions, legitimately and I'll consider that. I'm not sure If I'll have enough time to work on this, so please, be honest with your answers because I'm not going to fix the touchscreen, or maybe I will if it doesn't happen for everyone.
I experience dramatic touch screen freezes as well since the first time I installed Lollipop nightlies. (4 weeks now). Tried clearing cache, factory restores, de- and reinstalling apps. Reflash kernel, format SD, reinstalling gapps, puzzeling at logcat logs etc. Nothing helps. Random freezes from seconds till minutes. Only thing that 90% of the time will help is keep pressing powerbutton until screen becomes responsive. It happens more when I have a lot of (hangout or whatsapp) notifications, or when trying to type something (stock keyboard). Tried other keyboards: no luck. Tried every toggle: WiFi , Bluetooth etc. : no luck.
I experience dozens of freezes a day. Almost to the point that cm12 is completely unusable. Love this ROM, but this is a real showstopper.
1. No
2. AOSP Vanir 5.02
3. Since first availibility (12/14)
I experienced this issue on 2 roms in 2 forms
1. No (coming from Stock 14.4.A.0.108)
2. KitSlim_AMG [Evo 8.1] / iHackers advanced Stock Kernel
3. Since installing the Rom
This was the first time i experienced touch-issues. Not a freeze of the screen, but the screen sometimes started registering touch-events on the wrong places. This was temporarly fixed by locking/unlocking the display.
1. Yes (coming from KitSlim_AMG [Evo 8.1] )
2. crDroid-5.0.2-20150303-honami / 3.4.0-crDroid (packaged with rom)
3. Since installing the Rom a day ago
This time i get freezes. And they are much more frequent than those "ghost-inputs" from KitSlim_AMG. Unlocking the device also fixes it temporarly.

i did all could be done , problem emerged when i flashed custom rom , since then i had excessive hot , flashed stock firmware and just getting worse
is knox tripping the cause ? if not , then what ?
What you're saying shouldn't ideally happen. I've had Samsung devices for a while now, almost rooted every single one of them & found that the performance actually got better. Check for water damage, it's highly unlikely but it may be a culprit. If the problem persists, take it to Samsung (we all know their track record with heating batteries)

Knox being tripped would not cause overheating. Don't suppose an app you have installed is causing the issue?.
If your convinced the phone is overheating even if on stock firmware, I would think the problem is hardware related.
I suggest visiting a Samsung service centre.
IDK know about Knox problems but I have been having issues with Android 10 ever since I updated. It runs great for about 10-12 hours and then something happens... It starts getting hot, runs like crap, super slow, the face recognition will stop working... It gets do bad I can barely unlock the phone. A reboot seems to fix the problem but only temporarily. Inevitably it does it again
Edit: and just to add to that, when it's running good I get much better screen off battery life than I did on pie. Seems to run smoother but that may just be me. The battery life however is hugely different. I keep track of deep sleep stats and battery users with bbs and Gsam

i can say the one mistake i did was flashing the wrong version of lineage 17 ( accidentally and wiped all at once) , that where everything started , i was flashing many wrong roms in my ex-phones when i was very newbie , but non of them had overheating issue

Latest Stable Build ? Stability Issues on newest updates? (Advice for new Owners)

Hi, I recently ordered an x2 pro (Global) based on its great on paper specs and the huge amount of glowing reviews on YouTube. But after I ordered I read on Realme's forums and a little on here about users experiencing multiple bugs in the newest update (c26) Including but not limited to , massive battery drain, slower charging, phone overheating, decrease in SOT by as much as 60%+, low FPS in games (especially PUBG), lag in launcher, microphone not working in calls unless you cycle speakerphone on/off etc. So that's a bummer if true. My question is kind of a poll of how many are experiencing this, or if its everyone? And if it is everyone, what is the recommended newest build until a fix comes out ? How is c24? Is it worth the minor bugs to have the newer interface, or is it just as unstable where I should just avoid Realme UI all together right now and just get the latest Color OS build ? Thanks and I look forward to everyones opinions and info.​
Most of what you saw on C26 is not true ! What is true is loss of SOT primarily ! A significant portion of it ! Around 2 hours for me from 9 hours to 7 and that is really bad ! About PubG that is the game not the phone , to minimize "lag" use performance mode on game space ! Charging still is fine !
Remember most users are from India and summer is here so any phone will heat up .
What I recommend for most people that has their bootloader unlocked and has some custom recovery flashed is to go back to C24 . No battery problems and lags , is the best RealmeOS update FOR NOW !
Good luck ! You will love your new toy ?

Yeah the C24 android update is good , I can't find anywhere , but finally I found in Russian realme website , anyone wants to get this firmware , just download it from their site , the charging animation and the speed of the phone is also good .
Anyone know how to block the ota's ???
Thanks guys, going to install c24... It is prompting me to update to c26 from a10.... Anyone know how to disable ota's (temporarily) until a new update is out then I can turn it back on... If I knew what server it was checking I could block it or something. Anyone that know how to do this please let me know. Thanks in advance.
No real issues on c26 for me and I know a lot of people are happy,
No battery drain,in fact getting 10 and half hours SOT according to Accubattery,
Only charging once in the morning for 15 minutes,
Not a gamer so don't have the game lag that may just be an issue with the game such as PUBG,
No lag in launcher for me,using stock launcher with animations off,
Sound quality is actually louder and clearer for me than previous RUI updates
Only thing I did notice is occasionally hang in chrome where would just have to close chrome to get out.
C.24 I had worse issues with sound,hanging and phone restarting itself with flashing Realme logo.

Definitely,The newest update c27 is even better and as stable as colorOs,I Am in Europe but both the Indian and EU software is the same so you could get the software file from either support page and update, just download and use the file manager app to select the download file,

Question Are there people without ramdump?

today i've bought my new zenfone 8, i was leaving a xiaomi mi 10 because of proximity sensor problems and miui instability.
read lots of reviews about zenfone 8 and all were enthusiasts... today after buying it i found a first post about ramdump, since today afternoon i've read lots of posts....
i've seen my phone is 04/21 MFD....
will it die? are there people wich had this phone (04/21 batch) without problems? searching around in forums seems that anyone sooner or later had the problem... so the phone is in the box and i don't know if i will return it or keep it... give me a little trust in this phone
Do you like to play Russian Roulette?
If you open the box you will have to.
I have phone of same batch 04/2021 and had ramdump once. But I easilly quit it with keys combo. I do not know why it works for some but not for others.
so there are people who never had problems?
cause i could see 30 people having problems, but i'd like to know if are 30 people on 50 or 30 people on 1000, it would be a big difference
Mine is mfd 04/2021 and I still have no problems
There is 35 confirmed cases of this issue and it might not be the same issue as Ramdump is just something zenfone 8 falls back to when there is a problem with the phone. Who knows how many (tens of thousands) people are there without any issues.
I would say relax and enjoy your phone. Don't unlock the bootloader so you don't lose the warranty, but other than that just use it normally.
I just checked and I also have MFD 04.2021. I never had any problems (not that I am aware of) so I never bothered to check before. Does the problem only happen on certain devices? I have the basic version with 8 GB RAM and 128 GB ROM. Happy customer so far.
EDIT: I am running stock firmware, if that matters. Haven't altered anything (yet).
Used it for more than 4 months without problems (bootloader unlocked).
With Lineage 18.1, it worked great for a day, maybe even less. Now I get at least a couple ramdumps every day.
How do one check MFD?

The problem in the official forum is a "one time" thing, if you get the "waiting for flashing full ramdump", its bricked and you can't do a thing, beside sending it in.
On my brand new ZenPhone 8 running Lineage for Microg 8.1 October 7th version I'm getting the ramdump screen, but only under specific circumstances:
1. not connected to wifi/wifi off
2. on a call
3. have headphones plugged in to the jack
it almost always crashes within 20 seconds. If any of those conditions are not met it works fine (or at least appears to so far). I've tested this ~8 times in a row with all other (known) variables remaining constant.
When it crashes, pressing power for ~15 seconds shuts it down, and it can then be started normally. I hope this helps anyone else e countering the same problem.
Someone had this ramdump issue on unlocked bl but on stock rom? Especially with at least some magisk mods?

Yes! My first time with this issue. Never before.
I'm on the lastest Android 12 stock rom (UL-ASUS_I006D-ASUS-31.1010.0410.72-1.1.25-2204-user).
- Unlocked BL
- Rooted with Magisk 23
- Kirisakura_Sake_S_2.0.1 flashed with EXKM
- Only one Magisk module (Font_Manager-v5_6_4-117)
I was playing a game (Zombie Tsunami ). I got my screen freezing, ... dark screen and ramdump issue.
Edit: My MFD is 05.2021
I have too MF 4.2021 - using since 5-2021. I'm very happy with this phone. For all this time I'v got only landscape bug on video - fixed with OTA update.
I'm using stock soft - Android 12 31.1010.0410.72
