Anyone else having overheating issue?

[MENTION=8638808]kirtikhurana[/MENTION] I agree, I'd say there's a noticeable increase in battery drain while using the device when compared to LOS 16 (at least for me, clean flash). Personally, it's big enough that I decided to stay on 16, at least for now.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Tahir Baig:
YouTube video was getting stuck and there was no volume output from the speaker.I connected bluetooth headphones while keeping the stuttery video playing and voila! As soon as bluetooth was connected, the video became smooth and headphones were playing media volume normally.

While the video playing I disconnected bluetooth and it was back to the stutter and no media volume from speaker.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Mrinmay Medhi:
Yes I also back to Los 16. GCam green tint on front camera again come back in 6.1 version. Setting black level to 16 also not working. 7.1 apk working fine but the apk not very stable.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] slim71:
Adding to this from my experience, in case it helps.

-ROM working smoothly, no major issues.

-I've had the audio problem at the first boot: after a while the audio began to act like.... like the old crappy radio quality, if it's understandable :confused: after a restart, videos were stuttering and audio didn't work from YT or FB (the sources I've tried). After a second restart, everything is fine so far.

-the Gallery app I've found installed (I believe as stock, it's

com.android.gallery3d

) stops working if I try to access the "Video" section in the bottom bar (will do a log if useful)

-I don't really use it, but the stock email app (

com.android.email

) does not work at all, doesn't even start

-Trebuchet launcher does not work at all

Everything else seems good for now! Thank for the hard work! :victory:

After installing the new version I can't see the internal memory of the phone. Does anyone have the same problem or how to solve it?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] myjess:
I have no audio issues in vanced youtube to phone speaker.

My phone is encrypted if that has anything to do with it and there seems to be no way to first boot it into the OS without it encrypting.

Hey, Does dirty flashing LOS 17.1 fix the audio/video issue for anyone?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] P2 friend:
From my feeling, the battery life increased actually after the upgrade. Feeling really isn't a reliable indicator i think. Problem is, there is no easy way to compare the numbers empirically.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Tahir Baig:
No video stuttering or loss of audio when connected to bluetooth headset. But as soon as bluetooth is disconnected, back to video stutter and audio loss from speaker and also wired earphones.

So, at the moment there are no problems when bluetooth headset is used.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] SummerRainbowz:
[MENTION=10747581]P2 friend[/MENTION] The way I compared I compared is by doing the same things in both roms under similar circumstances. For example, going through posts on a Reddit app I would usually drain 1% over 10+ mins on 16, but with 17 the drain can happen in even 6 mins. Sometimes it gets to 10 mins, but never as high as LOS 16.

Nonetheless, this is just my experience, YMMV.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] geek.x86:
Luckily, I haven't run into any of the issues mentioned here by the other members. YouTube Vanced works perfectly for me and no audio issues as well.

I did a clean flash of the ROM along with nano Gapps. I have also rooted my phone using Magisk. This ROM is excellent and it works smoothly. I really love the system wide dark mode.

From Marshmallow to Android 10, our beloved Lenovo P2 has come a long way. :)

Thanks a lot [MENTION=840484]Mike F[/MENTION]or all your hard work. :good: :)
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Sutcliffe9:
l did exactly the same and everything is fine.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] :
Tell that after a reboot or two, audio problem would occur. Although Overall the rom is very good.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] geek.x86:
Okay, I rebooted my device 5 times and after each reboot I checked both YouTube and Spotify to see if any of those problems occurred. Fortunately, nothing happened. Both apps were working exactly as they should. Spotify took a little longer than usual after the third reboot though.

I really don't know how to explain this but I am happy anyway. :)

Hi,

I changed twrp with recommended version - 3.2.3, but the problem is the same with today build.

Thanks in advance
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] SyB0rg:
I think I'm confused. People who restore boot.img (basically, OS kernel) - you just downgrade the newest release to 25 Oct release (because Linux= kernel), what's the point in doing so?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Lyceus:
The issue still occurs on build 13.12. I was trying to get some logs with instructions provided here but without any result :(
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kielbek:
I'm sure you will get no answer to that as I believe people don't even exactly know what are they doing. Welcome to XDA forums.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] simbanono:
And people will tell you that you are crazy if you run android 9 because latest release is always prefered over anything thats stable, thats the attitude people have here.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kielbek:
Not encountered this yet, but I can imagine this to be true. Personally, I moved since previous lineage has some irritating bugs like phone muting itself after a call and some others I can't remember right now. Unfortunately, current one has some irritating bugs too, one which I reported and found workaround for now, but apparently Mike has no time for this and is preparing to hop on the next version already. Hopes we can get 18 stable quickly and squash irritating bugs so we can finally settle down.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] simbanono:
Its not just mike, its just everyone wanting to jump on the Android 11 bandwagon, in which the devs gets pulled into. But alas thats what the community truly want, ie buggy and battery draining lineageos versions, and a dev that wont respond to anyone saying that the battery drain is bad, and not admitting it either.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] techpnv:
Perfomed a clean installation of latest lineage os lineage-17.1-20201213 with TWRP 3.3.1-1 working very good till now. Will update later if any issue occur.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
For people that have issues booting: if you ever used a different TWRP than the recommended one since you set up the phone, or used a different TWRP to format userdata, your userdata is incompatible and this is most likely your boot issue. You should take a backup and set up the device from scratch using only the recommended installation methods.

Sadly I didn't find anyone provide the exact setup they have to reproduce this bug, and I tried upgrading both of my P2s and my friend's P2 without having any issue. Clean install working fine as well. If I don't get more info until next week I'm going to disable builds indefinitely since this is going on for almost 2 months now.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
f2fs just keeps causing issues, I would not recommend using it. On P2 we had big issues in the past as well since lenovo used a very old f2fs kernel driver that was incompatible with modern f2fs driver.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kielbek:
Personally, I tried doing that on both ext4 and f2fs /data with recommended TWRP when fresh formatting my phone about a month ago or so due to already reported issue. Played with it a bit and it just didn't work in here. Previously I didn't have any other TWRP than recommended since Lineage 16.

I assumed back in a day that there might be differences between a42's dependent on production dates/release markets. I can't confirm it in any way but maybe there's some truth in that.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kielbek:
I thought you are talking about basic forums users who are installing experimental things and do some random "tweaks" breaking their ROMs even more.

I mean, it's developers forum after all. And Lineage is about security and privacy, so it requires latest versions to maintain that status. Afaik Google drops support for older android versions as soon as new one is released, so no security patches. I believe maintenance of older version by backporting security patches and software is a genuine pain in the ass. I'm not sure about current status of that because they wanted to change that a bit since Oreo, but yeah.

Stability wouldn't be a problem if we would be able to get full source code for every bit of phone hardware, not just hack blobs to work with custom ROMs.

But still, Lineage team is holding releases until major stability issues are fixed, unexpected bugs do might happen tho.

@mikeioannina No problems here with F2FS on either LineageOS 16 or LineageOS 17.1 (and no matter the TWRP version). The only 'problem' that I've encounterd is the noticeably higher battery consumption on 17.1.

Maybe this is something that will be fixed by 18.1 :D
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] en666:
Lenovo P2 p2c72 normalised p2a42. Using as a daily drive.

Clean Installed LOS 16 with twrp 3.3.1.0, ext4 partitions and root. Updating following releases with the updater after having removed the pin on boot.

As soon as 17.1 came out ( tx Mike!): cleaned installed LOS 17.1, twrp 3.3.1.1, ext4 partitions and magisk. Had initial audio bug with media, then resolved later.

Currently on 17.1, twrp 3.4, ext4 partitions and magisk. Updating every build with the updater app. Looking forward for 18.1!

In my case it was trebuchet. Used Nova instead, battery life was back, more or less

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] SummerRainbowz:
@mispp I don't think that's enough to debug this issue, since Mike can't reproduce it (neither can I for that matter).

If you could grab console-ramoops via adb by using "adb pull /sys/fs/pstore/console-ramoops console-ramoops" for example and then post it here I think that could help a lot in debugging this issue.

Also, one more thing. It would be nice if we were told what actually needs to be delivered/will be helpful in order to debug the issue in this case.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mahmutpekkara:

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] kocapomak:
I tried that recovery because other recoveries installation is not working. October 25 lineage recovery can clean and load the phone. The lineage recoveries that come with the November updates cannot operate on the phone. i think november and next updates have a problem accessing the phone memory.

Lenovo P2a42 with recommended twrp 3.2.3-20190209 (never used any other twrp and did a fresh install from 16.0 using the same recovery a few months back when 17.1 was available). Not rooted. Data partition was always set to ext4.

Lineage 17.1 25th October 2020- boots fine when updated using the built in updater.

Lineage 17.1 after 25th oct onwards phone gets stuck in bootloop when updated using updater.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] kocapomak:
I just checked basic functions. I got a report with Aida64. I compared it with 17.1. I looked at the kernel version. Then I restored it to 17.1.
