14 June 17.1 on P2C72 flashed with twrp 3311 here.

I had the 17.1 since the first official, April 2020 and with the daily use I can report battery lasting almost 8 hours on screen usage, which is a lot less than Los 16.0.

However, similar to what mentioned in this thread, the problem for me about the battery drain was caused by the three navigation buttons; so I set the two navigation buttons instead. Well, I can confirm that using the two buttons, as weird as it sounds, battery suddenly passed from a constant 'less than 8 hours' to 'more than 11 hours' screen usage. Now I need to check if 11 hours will be the new standard.

I have no idea why it works but it does. Plus, when you get used to the two buttons, you won't come back!

Thanks again to Mike to support this wonderful project and keep this amazing device live! I'll keep you posted with further updates.

Would you mind posting what you did here exactly, i.e. Which two buttons? Sounds like a noval fix!
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] en666:
Hi there, yes sure. You can enable the two buttons navigation bar by going to Settings > System > Gestures > System navigation > select the "2-buttons navigation" option, that's it.

Quick battery update: I am currently writing this message at 44% battery after 8 hours of Screen usage.

How about overnight battery drain? Does it also get improved after switching?

Can someone provide installation instructions for NON rooted devices.

Thanks in advance

2TOGGLE

No way

CHEERS
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] wodaaa:
for me, the change of gestures does not make any difference in battery consumption, a radical reduction in battery consumption occurs when data saving is enabled.

it would be great if dev added p2oggle to rom ;)
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] vikas.baloda:
Can you share details how you able to get 8 hrs SoT and still 44% battery left.

Like which apps and magisk modules u using.

Thanks in advance.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] topoldo:
First of all, I would like to THANK again VERY MUCH, Mike for his hard work!

I waited until yesterday to move from LOS 16.0 to 17.1 because of reports concerning problems with audio/video.

Yesterday I migrated simply by:

a) updating TWRP from 3.2.3 kuntao to 3.3.3.1 (probably not necessary , but I did it 'just in ca'se because of some reports)

b) wiping cache and dalvik

c) flashing LOS 17.1 20200614 + GApps nano

I did not format any partition being with ext4fs in any of them.

No rooting, no Magisk.

In these conditions I did not have any problems neither during reboot nor while accessing for a test all my apps (my settings reports they are 106).

So a real BIG THANK to Mike!

I have a general question about status bar: I did not find any way to make it to stay permanently visible omn the screen as I was used with all previous versions.

I can only swipe down to browse it.

Did I miss some flag/option or it is really impossible to have this in LOS 17.1 unless you find a thrid part program which do the trick?

TIA for any answer!

Topoldo
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] vikas.baloda:
I faced same problem.

Format data and system then reinstall LOS 17.1.

It will work like butter smooth.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] en666:
I never tracked the overnight battery drain because I normally switch it off or put in flight mode.

I would not know to answer your question, the only thing I can say is that the battery drain chart always shows a flat line overnigth. This is true for me with all OSes: stock, los16 and los17.1.

I have tried the gesture once, but I didn't really like it and returned back to the navbar. So no, unfortunately I do not know if gestures affects battery life.

"P2oggle uses the kernel's input event interface (evdev) directly. It therefore requires a rooted device"

Link to the XDA page: https://xdaforums.com/lenovo-p2/themes/p2oggle-t3965418

If you want to root your P2 first, there is no "native root" available anymore for 17.1. Install magisk instead.

Now the most impopular thought: to be honest, after the intial hype, I am not using the button since weeks now.

What I mean is that the app itself is supercool, but the added value that this very P2 physical button gives to you on a daily basis is marginal.

Yes, sure: my "P2C72 with LOS17.1(20200614) flashed with twrp 3311" is always in dark mode and generally all the apps I use as well. I personally more like dark than bright.

Automated display brightness enabled.

Magisk 20.4 and Magisk Manager 7.5.1 installed, no extra modules installed.

P2oogle installed but not really using.

The apps I more use in this lockdown era are Musicolet (both bluetooth and speaker sound), Opera Browser, vanced Youtube (mostly bluetooth sound), Telegram (mostly bluetooth sound) and Whatsapp (always on videoconferencing, both bluetooth and speaker sound). Therefore, these apps are the most responsible for the drain of the battery, which has the performance profile set to "balanced" 99% of the time.

Reached the 15% battery, the "Extreme Power Saver" enables automatically. I always try to charge the battery just when it goes below 15% because lithium batteries prefer not to wait until they are completely decharged.

Quick battery update: from the last 44%, I've left draining it until 4% before charging it. So, reports since the last full charge: 12 hourse and 30 minutes Screen Usage, 36 hours in total.

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

Whenever I use bluetooth headphones with wifi, the wifi speeds reduce drastically. This was a problem on LOS 16 as well.

I am forced to switch to mobile data to maintain a stable internet when using bluetooth headset.

Does this happen to anyone else?

If yes, the this is probably a bug.

P.S- I tried it with different bluetooth headset and the same problem. Hence, It is not the bluetooth headset fault.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] wodaaa:
I use a smartwatch on bluetooth and I have the same problem, the wifi speed drops to almost zero, after turning off the bluetooth the problem disappears ....

Ps. I tried it with different wifi router, and the same problem.

I think this is a common problem since Los 16. When i open Bluetooth, there is no problem. But after connecting a Bluetooth device (watch or headset or any device) wifi reduces 3-4 Mbits Max.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kielbek:
4Mbps reduction is not that much tbh. Unless you're saying that you can achieve max speeds of 4 Mbps. Are you using 2.4 or 5 GHz network?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] leo_97:
I disagree. I use p2oogle with flashlight function and I use it almost everyday to turn on or off my flash without having to turn the screen on and unlocking the phone. IMO the app is superb.

Bluetooth and WiFi use the same frequency 2.4GHz, if you are connected on a 2.4GHz on any router, you'll have the same speed problem and this is with all roms and all phones, you must use a 5GHz network band to resolve the speed problem.

Hmm it's odd for me. I just did a clean wipe (formatted data, system and cache), reinstalled using twrp 3.3.3.1 and I still have the same jerky video issue where it takes a few restarts to get it smooth. Have I missed something? Do I need to dump the internal storage?

connected2.me app crash

dear kuntao-lovers,

I already reported this via GitLab. But I wanted to make sure this does not happen only to me. Since LineageOS 16, connected2.me app crashes in few seconds after launch. I would appreciate if anyone else check. I hoped it would be fixed after 17.1, but the issue is still there.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] yajdintaydemir:
There is a noticable wifi speed drop when i'm connected to a bluetooth headphone. Is there any way to fix it or do i have to change roms?

Thanks in advance.

I just installed los 17.1. It works smootly so far. Thanks a lot to Mike.

The only issue I have is with finger button gestures: they work but there is no haptic feedback, i.e., when you touch the button the phone does not vibrate. Is there a way to acivate vibration on to gestures?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] en666:
If you are referring to a file ~20MB big that has 'recovery' in the name, that is the LineageOS official recovery. Anyway, if you are asking this question it means that you must be quite new to the CROMS world. For this reason pay extra attention and deeply study before doing anything, otherwise you may also brick your P2...

When you'll be familiar with the concepts of this world, follow the official LineageOS guide to flash the recovery and the os!

I normally try to be nice but this type of sheer arrogance cannot be ignored. The person was simply asking what it is, not why the whole world should come crashing down in a post reply. Please try to be friendly to people here, there is no need to super brag about the superiority of people who can copy Roms.

It's a TWRP style replacement with some less features and a couple more. I'm not aware of many people using it however, I think virtually everyone uses twrp. My view is stick with twrp :)
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] en666:
It was genuinely not my intention to be arrogant and I apologise if my advice has hurt someone.

What are the pros & cons of Lineage recovery over TWRP?

Can Magisk work with Lineage recovery?

Can root still be disabled when using wallet/banking apps?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] vipgod:
System app remover not working!!!
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] blofse:
I can answer the second two:

[*] Magisk works with linageos.

[*] with magisk hide, reinstalled using a different manager name, the banking app selected in the hidden list, and twrp directory renamed on the internal root folder, my bank app works fine. This obviously may not be applicable for all, but I think most work in this way.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] salobar:
I have faced the similar problem. But before update O have updated the Twrp. Then I updated 24.06. Android did not start. I formated all partitions and flashed 24.06 version. Everything is ok now.

Thanks Mike for bringing official Los 17.1 support for lenovo P2.

Everything is working fine except the following-

1.I'm unable to update or download apps from playstore from my Sim1(jio) mobile network. I'm able to download and install apps from my Sim2 (bsnl) mobile network. Tried clearing cache data of both play services and play store but didnt work. In Los 16 it was working fine.

2.Another issue happens when switching mobile data from sim1 to sim2. The toggle works and data on Sim1 gets disconnected but data on Sim2 doesn't get activated. In order to use data connection on Sim2 I have to turn flight mode on and off or restart the mobile and then data connection on Sim2 gets activated.

3.Volte doesn't work on Sim2.

Going to install lineage17.1 freshly and try again. If issues persist then back to Los 16 again.

Hi,

I was used lineageos 17.1 version 2020-06-14 and i want update 2020-06-21 version. I used linageos updater, it downloaded new version and phone started recovery mode, it installed automatically and restarted. Phone not started after android startup pattern, it stay 3-5 minutes on lineage animation after restart recovery mode.

I try wipe dalvik and cache and i install zip file manual with twrp in data/linageos_updates folder but its same. How i solve problem without data loss. Thanks and sorry my english.

Why would you want to remove system apps? Whenever you will update the ROM; system apps will come right back. Freeze them instead.

Hello, I am reposting a question I posted before since I did not get any answer.

I am using Los 17.1 with fingerprint gestures. They work but I miss the haptic feedback (vibration) which was present in Los 16. Is this a common behavior? Is there a way to re-enable this feedback? Notice that I have vibration on for keyboard press and it works perfectly.

You must have been connected to WiFi and having a low cellular signal. Truecaller detects a calling signal and processes information of caller through WiFi. But, your phone doesn't connect call as it is not feasible under low signals.

Here P2 (P2C72) moved on LOS17.1 from LOS16 using twrp3.3.1.1. Keeping P2 updated through the updater app and I am currently on 20200628.

For me Google Pay works with Magisk, both hiding and not hiding the app. What I normally do after every update is going to twrp and wipe dalvik and cache.

Sound problem disappeared since version 20200614 if I don't remember wrong.

I still have though a massive battery drain after the last release. 8-9 hours on screen usage and about 24hours in total. Which is still a lot for a normal phone, but not for p2: I used to charge it every 3 days with stock and los16.
