Build from 25.05, problems so far:

- constantly losing cellular signal - full signal for few moments, then bars go to 0 signal strength, after few seconds it goes back to full signal.

Another bug in this build:

- automatic brightness doesn't work. It never adjust correct brightness in light-changing environment. Even when night is coming. Or today morning I wake up and after unlocking the phone brightness is still set to the smallest possible.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
I do not have that issue. It is working perfectly.

LTE signal issue

Hi all

I am LOS 7.1.2 18 May build.

I have been facing issues with LTE signals from the very first day of installing the ROM . I have switched to 3G as an alternate .

Can any one please advise any solution for the same .

Thanks
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
It is not really an issue. Icon only shows fluctuations but the signal does not fluctuates. AFAIK this issue is already reported to LOS team.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] XDA xXX:
Thanks for the answer !!

as per status of my signal it is -87 DBm 52 asu ?

Is it good ?

I am not sure what asu value is considered good !

On 3G it is around 81 DBM 15 ASU
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] lozohcum:
Messenger (full and lite) doesn't work. It shows error that there's no internet connection.

Auto brightness works but it's buggy af. And it has big delays.

Under 20% battery life internet connection is misbehaving.

Even when I turn off the batter saver, apps have problem with multiple disconnections.

Performance is degraded but acceptable. Battery life is far from what I expected, big + for that.

Speakers sound is awful. On Stock sound was very clear with no distortion. On LOS it's like on old speaker from 2000y phone.

The 2nd sim stopped working in front of my eyes, i was using it. Network got fluctuations on both & until i removed 2nd sim now first sim is working.

Should i try IMEI changer for second slot? also where can i find 2nd imei because only 1 IMEI showing on both.

EDIT: I clean fladhed los14.1 again & both IMEI are now showing different & both sims are working.

i installed this rom in my p2. after installing when i rebooted, the screen goes black with the blue led on and the phone vibrates for 2-3seconds and stops. what do i do?? I had installed it forst but due to certain bugs i thought of going to AOSP. AOSP during installation shows me an error stating partioning system image unconditionally. after that i tried installing LOS14.1, the screen goes black with blue LED.

Can you try measuring the current using the app called "Ampere" by Braintrapp.

I shifted to AOSP Extended Orea and the 'Ampere' app shows current input of over 4300mA while charging at 30% battery. And the phone fully charges in around 2 Hours.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
The Ampere APP isn't supported since Lenovo Nougat kernel.

It was with Lenovo marshmallow Kernel. So whatever kernel your AOSP ROM uses the dev either ported the drivers required from marshmallow to nougat or his kernel is still marshmallow based. Just FYI. a full charge from 0% to 100% takes about 2h's on LOS as well.

HI guys. The last nightly update messed up my phone.

I installed it via OTA. Then, at startup, after inserting the password it gets stuck in the LOS loading animation.

I tried to wipe cache and dalvik cache, to adb sideload the same rom, without any difference.

If it is relevant, I have magisk installed and hidden.

Should I switch back to the previous nightly, or is there anything that I can do?

UPDATE: flashing the previous nightly didn't help. So I uninstalled magisk by flashing the uninstaller, then I flashed the last LOS nightly and OpenGApps, and that worked. I reinstalled magisk at the and.

I've learned a lesson I guess ;)
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] :
Go to twrp. Wipe/Advanced Wipe, and delete everything.

Afterwards, in Advanced Wipe menu, click on Repair or Change File System. Try this in all partitions you were able to.

Finally, install LineageOS (from Sdcard or USB On the Go)

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] duck from space:
Oh dear this is it, take my money.

After 3 days of use I concur to all the good critics already made before. This is as expected hands down the best and most refined rom for the p2.

Also, all my mandatory toys works flawlessly...

-Magisk and a bunch of modules: check (expected).

-Substratum legacy: check. Use swift themes / don't mod android system though.

-Micro G (via nanodroid): check !

-Xposed running Gravity box, Afwall+ and XprivacyLua: check !

Wondering if the nanodroid patcher will make all of this pass trough ota without pain, we will see.

Thanks Mike / HigwayStar !

Nice and stable

Hello everyone,

Writing this review after using it from the day it was available to download :

* Battery life is amazing.

* performance is great.

* everything works as expected.

* camera quality is also good ( + 2 exposure value helps in low light video recording)

* using Stock camera, footej and google camera.

* Using swift dark in substratum engine.

* Though stock audio quality is also good, using viper4arise magnus mod.

* Rooted with magisk.

Though one thing I like to mention is I am facing problem of scrolling glitches. Small lagginess during normal operation.

I am not sure whether others are facing this problem or it is only me.

Thanks a lot OP and other devs who contributed. ?✌?

If you follow the instructions on the wiki you don't have any problem for installation.

If for the one key you mean the left button for power save it’s disable on this rom.

I don't see any wifi bug.

The phone is warm only when charging as with stock.

For me it's ok as daily driver.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
Some update on 15.1, everything is working but treble is kept disabled for now, as it "breaks" fingerprint gestures, glove mode and some livedisplay options. It can be enabled later when I find some more time to look into the issues, but let's not make it a blocker to ship official builds.

I just need to test a clean install for any issues and SELinux denials and I need someone to test VoLTE. My life is getting busier during summer at work, but now I use kuntao as daily driver again to spot any potential issues.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] shabab malik:

It's good to just upload the beta build publicly and not for just some members. And i don't think Mike will release any beta before official because he is using this device for daily uses and he know what's working or not except VoLTE which is not a major bug for some users. As he said that everything is working i guess there will be a official Lineage 15.1 in next week. Hope mike will give the update about the development of this project when he will be free.

No , airtel Volte works on 2300 and 1800 bands same as jio , infact jio support extra band of 850. In airtel volte they extensively us LTE-A for better bandwidth allocation, carrier aggression and fall back to 2g/3g is available. Jio usually use single band method. So , there is some stuff lyk channel coding involved in this i guess.

Guys, I keep on doing something wrong when I update to a newer nightly.

If I update from LineageOS updates, the phone gets stuck on LOS loading animation after asking for security pin.

I tried to manually flash the nightly, opengapps and magisk, and I struggled that way as well: it only worked after several attempts, and the gapps were screwed. All gapps were crashing and the Play Store was looping in "Checking info", without ever adding the account. I reinstalled gapps several times (I use the nano version), but without any improvements.

The only way to fix back everything was to wipe all partitions (data included) and to reinstall and set up every single thing once again. Too much of a struggle. There must be a better way of doing it. Please advise me what I am doing wrong, and how to do it right next week. I need to learn how to do it right.

If I sideloading the build, the phone is starting normal.

Any ideas?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] danielcepa:
i have zero problems with updates.

my setup:

twrp from the lineageos wiki

f2fs data partition, reformatted with twrp (as suggested in this thread)

vfat sdcard, default

encrypted, using fingerprint unlock

opengapps nano

no root, no magisk, no substratum

all these problems are twrp, filesystem or magisk related. start over using the official lineageos guide

cheers, amazing bugless rom!

thanks mike and the team
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Uniposka:
I had to format data to ext4 the first time I flashed LOS, as I was experiencing another issue (screen black with blue led and long vibration on startup) and I was advised to do so.

I use Magisk.

All the rest is identical to danielcepa's setup.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] danielcepa:
You can use F2FS without the blue led error.

The Black screen bug happens when using the default F2FS filesystem coming from the stock rom. It was suggested to Format to Ext4 -> reboot recovery -> Format back to F2FS -> install LineageOS/Gapps

Magisk is not officially supported, so the devs cant really help with that. I had bugs related to encryption and f2fs with it, so im not using it anymore
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Uniposka:
Ok, so what would you advise me to do with the filesystem of data? Format it again to F2FS, or leave it as it is, since it is working?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] danielcepa:
If you can live without magisk, do the f2fs thing (format to ext4, reboot twrp, format back to f2fs). Everything works great with this setup - encryption, updates, etc.

If you need magisk, stay on ext4 and hope for the best.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Uniposka:
I need it for a few apps, particularly the banking ones.

Thank you for your advice.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
There is a f2fs workaround in the magisk mods list that works fine. You just download through magisk and install the zip through TWRP. Also works with OTA updates.

If for some reason you need to wipe your cache you need to install the workaround through TWRP again.

Alternatively use ext4. I find this better than f2fs. I was using f2fs for a while and found it caused little jitters with animation in the OS. Switch to ext4 and it was smoother.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Uniposka:
For me everything works fine as well, but just until I update to a newer nightly. Then, what I explained previously happens. I want to understand how to update without any risks.
