Flashed it from TWRP. Seems to be working well at the moment. The only thing I noticed is that the ringtone when it plays when being called is stuttering. When you are in the menu to select the ringtone it plays normally...

I have seen a couple of posts regarding 'cast'. I am on 6th June release. I have tested cast both by casting my screen, and by using bbc iplayer to cast a series (I watched the lot 6 episodes). I can confirm that cast works perfectly (it was casted to a gen1 chromecast). I have the P2a42. I did a clean install even formatting system. I have no root/magisk. I used the recommended recovery image (lineage not twrp) and also flashed the recommended gapps.

After a week of use so far I have found no issues related to anything including: making and receiving phones calls, google photos, whatasapp, all of which seem to function perfectly. (Note: i have not tested video calls in whatsapp only voice and messages.) The only issue I had was at install, I could not 'see' my google backup even though it was there, so have lost call logs and old messages.

So many thanks Mike for an excellent job and all your hard work.
Hi numenory, is Poweroff Alarm (the Alarm which is set at sleep time to wake Lenovo P2 in morning for ringing Alarm. I switch off my P2 at night) working for you?? Also for me, Quick Tiles Drop-down Setting button crashes when touched. Please check and inform. Thanks.

Hi, I like the new customized Android version very much and it works really great.
Btw kudos to you Mike for your support and hard work.

I have a very important question. I have been a new prepaid Telekom user from Germany for 1 month and would like to use VoLTE, as this is included in my tariff. Unfortunately, this does not work with the last Android Nougat Original Firmware, nor with this Custom Rom. I have also made all specific settings, such as activating the VoLTE marking, adjusted Apn settings, etc.

Is VoLTE really only available in India for this device?

Lenovo p2c72, twrp 3.5.1, magisk 23, ext4 partitions, pin unlocked, updated to 18.1 2021-06-20 with the updater app. Everything smooth. Fantastic 18.1 ROM, thanks a lot Mike.

High battery consumption in 17.1 forced me to go to Nova launcher to save a little bit more of juice. With 18.1 it's now a couple of days I am back to Trebuchet, it seems it is working just fine, no major battery drain so far.

The cast we're talking about is the android built-in cast that shows everything happening in your screen. It doesn't affect apps with their own private cast functionality, because those simply require a network connection to work.
The casts I was talking about were both the what is happening on your screen and app casting. Both work as described in my post.

I must admit I have never used an alarm when phone is switched off, but I have tested and it does not work for me. I also tried installing the google clock from the play store which also did not work. I do have a pin lock set on boot. I set the alarm for about 8 minutes from shutdown.

With regard to Quick Tiles, I have had no issues.

Lucky you. Not all of us get to have a working cast. I wish it worked for me. I have no idea why it would work on some and not in others. Maybe your TV has a different version of the cast protocol or maybe you installed something that replaces the default cast that comes with the ROM. Please let us know if you did something to get it working. We would appreciate it :)

I have not installed anything additional, nor have I rooted. My original post details the 18.1 version etc and how I installed the rom. I am using a Google Chromecast gen1 plugged into an hdmi as per original post. When I get chance I will try with a later gen chromecast, but I do not own one, so this will only be when I mange to visit a friend that has one.

Ah you use chromecast. The one that doesn't work is not chromecast. It's called miracast I think. You don't need any hdmi adapter or anything like that. It connects directly (or through the router) from your phone/laptop wifi to your TV wifi.

I have heard of but have never used a miracast and I believe they use a different protocol to the proprietary chromecasts. TVs such as sony (probably not all models) include built in google chromecast, again, I do not have one but know somebody with one and will test when i see him. It does not surprise me that miracast does not work. I also have a hisense tv, which i can send youtube to directly from my phone but nothing else, this was the same on 17.1, I do not know what protocol/system it uses, I have not looked in to it. If the problem is the miracast I would suggest a possible solution of replacing with a chromecast gen 3, which in the uk at least are available for £20, again I have not tested a gen 3.

Miracast is the protocol's name. In 17.1 I could cast my phone's screen to a LG TV, now with 18.1 it stops in the initial connecting step.

Arrr good luck, apologies for the pointless reply, just interested. Is it affecting all android 11 custom roms or just just the P2 custom ones and is it an issue with Android 11 (non custom oem roms) generally?

My phone is on stock android 7... can i install this now, or will it need another rom first ?
Number of years since I did this, but I started with android 7 and it works fine. Follow the instructions at the start of page 1 of the thread. The first step if you haven't is unlocking the bootloader, this used to take about 2 weeks from memory which is a Lenovo limitation, you request it, and then it counts down the days.

Lenovo P2
Installed with full clean format with lineage os recovery, there is no problem so far! Excellent work @mikeioannina and the all other respectful devs! Even audio cracking bug is gone! Only minor issue is phone not automaticly waking up for alarm when it is off.

Edit: Just remembered there was an issue when you first setup the phone, google first setup app crashed and phone freezed. I forcly closed phone (hold power button for 10 seconds) , rebooted and problem is gone. I suppose this problem was coming from indicated gaaps. Maybe we need updated or other gaaps.
