I wrote about this issue a few months back, but it's still there.

I'm in an area with bad - fluctuating - reception. Sometimes when the phone loses the signal it's gone for good, even if I go to a place with good coverage after. The only solution is to reboot the phone.

Whenever I'm somewhere with good reception for a few days the problem doesn't occur, not once.

Anyone else experiencing this?

Has anyone had any luck installing another kernel with LOS? Tried the magma kernel but doesn't seem to work for me.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] binaryhelix:
Interested in the same question.

I am currently on LOS 14.1 2018-07-06 and am experiencing high battery use of kernel - 15% (stats checked using GSAM with root) after 1d 2h 20m mixed use (4hrs SOT)

Is this normal? Would this issue be resolved by installing another kernel or moving up to 15.1?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nihil39:
There is a known bug with deepsleep when using mobile data in LOS 15.1. It can be worked around by turning wifi hotspot on and off after switching from Wifi to mobile data. Apart from that the battery consumption is good.

Why [MENTION=3839575]mikeioannina[/MENTION] not addressing this issue. Since it affecting many users!!.

The issue already reported in jira also !
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
He's does everything in his spare time. Without him your P2 wouldn't have official LOS at all so quit nagging.

Everything takes time and besides that he is also working on Pie. And probably that issue is resolved in the new version. And like already mentioned more than 100 times before not everyone has the deep sleep issue so how can he solve it of the "issue" does not affect everyone?

Right almost impossible, so why don't you give an example and solve it yourself or wait patiently until 1 of the very few dev's for this phone comes with a solution.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
I don't think that's normal.

I would say it's worth trying 15.1. I get about 10 hours SOT on a good day.

If you're not happy with it you could go back to 14.

I never thought we would come this far(Android p) thankyou mike.

Please elaborate a little bit
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] satej@123:
I thought we would never see android pie for p2 (the day would never come) since there are very few developers. And is not popular as Moto phones which has a huge development base. Android pie is on the way and I am very happy.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] livy:
Do you pay for this? No?

Are you going to fix the issues? No?

Do you dedicate your spare time fixing bugs in the ROMs, for people like you to come in and complain when mike's doing a great job. No?

So sit down, shut up and enjoy the ROM, a d quit complaining, or do something about it.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] satej@123:
Rightly said.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] MAILUS:
I'm not here to blame anything that's not working. I don't want to trigger those also. I'm happy with whatever Mike delivered to us.

It just a normal question since it was affecting many users and JIRA also bug also raised. I don't know why these harsh replies to that. If my question bothers you my apologies

I agree he is one of the dev and most expected dev to push our device into official LOS tag.

I always appreciate Mike work and will do in future also.

Recently Mike gave few minor fixes for this oreo version only.

I raised the question to know whether he needs any support us or any particular thing blocking or is it hold for next pie release?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] blofse:
Can this also be fixed by restarting your phone? I typically turn mine off overnight (thanks for to the auto restart with alarm feature) so I presume I'm ok again until I switch on WiFi following a restart?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
Restarting the phone and also toggling WiFi hotspot fix the issue temporarily until you leave WiFi area for data again. I've got into the habit of toggling the WiFi hotspot off the quick settings notification. Just makes it quicker.

Does substratum theming work properly on LOS 15.1? Has anyone tried substratum on this ROM? If yes, then pls give a review....
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] satej@123:
I am using it. But for some reason the phone app is getting error, rest all is good.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Tahir Baig:
Oh okay. Thanks for the quick reply
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Kevindiepenmaat:
I wouldn't use it though (my opinion). I've read more posts of users who had issues with substratum.

And when pie is being released I doub't if it will work

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] satej@123:
What's in the latest update?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
This might be a stupid question but I'm going to ask it anyway..

Now that the updates have moved to nightly, where the updates section states no updates (ie blank as attached screens shot) does that mean there are literally no updates, or are there some updates behind the scenes that are not listened?

In other words is it pointless updating if there are no listed updates?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] mikeioannina:
Right. We got offered double the build machines vs what we had before so we can switch devices to nightly builds now. This allows making device changes without having to wait a week for it to be compiled and tested by users.

For example, for the next builds I fixed the mismatching headphones volume that I broke while increasing earpiece volume :)

I tried merging my latest kernel changes without updating f2fs but sadly the conflicts are getting very nasty and it doesn't even compile without reverting a big series of commits, so wifi issues that some people had will persist for now.

Pie work is a bit delayed because I'm working on rebasing kernel on top of pie kernel base. Sadly CAF managed to mess it up so I am slowly fixing all the mismerges they have done. There is also a chance kuntao will be under a new codename when pie is released (kuntaox) and it will be incompatible with kuntao builds/recoveries to avoid the f2fs mess that we have now. I am strongly thinking to remove f2fs completely in pie as I am pretty sure it will come stab us at some point in the future again.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nozav:
I've never met this bug so I wouldn't call it "massive". And this ROM is excellent.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] rogat92:
But Mike, the fix is in lineage-16 branch, isn't it strange?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] donjoe0:
So far I've found that it responds to the Performance Profile in the Battery menu: with no SIM card, no network traffic and no app usage I find that the "Power save" end of the slider gets me a little over 0.2% / hour of total drain while the bug is active (CPU at 100% even while reporting "deep sleep" in the stats), while the "Performance" end of the slider pushes it to 0.5-0.8% / hour. I guess I'll finally move my SIM card and my data into this phone and actually start using it now that I know I have at least some partial workaround for the problem. In no way would it be acceptable for a 5 Ah battery to drain at 0.5% / hour while the phone is doing literally nothing for me, whereas my old Redmi 3 was draining by the same percentage while connected to the mobile network and my Bluetooth devices and getting some light usage, all while having only 4 Ah of battery.

I have 3 problems on lineageos :

1) fast battery drain by "google play services" with gapps "nano" and "stock"

2) i can't format the /data without change partition type "ext4" to "ext4"...

3) i can't use ota to update my phone because when i click on "install" button the phone restart and go to TWRP and nothing else... i can restart the phone but without the launched update.

By the way, thanks for your work Mike
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Mr.T_shaggy:
For the point 3, disable all the lock screen security (like Patter/Pin/fingure print) and then install the updates.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Fangstergangsta:
Ok, i will try for the next update

People, would it be possible to set specific times for LiveDisplay to switch the night mode on and off? Because at the moment for me the tint starts too early in the evening.

I find it stupid that there is a setting for the color temperature, but not for scheduling...
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Geo42:
Mike has done an amazing job in the last update of 14 November. I believe it is the best rom everything works perfect. The only thing i have encountered is that the play store is of grey colour but works perfectly so i don't really mind. As for the slot sim 1 that didn't work i looked it thoroughly it isn't hardware problem it seems to be my carrier's sim that doesn't work because i tried another friends sim of another carrier and worked fine.

Problem with sim slot 1 solved. I went to my carrier they gave me a new sim card and everything works perfect. So my phone was fine as well as the ROM which is awesome. The problem was my sim card from the beginning
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Cuvillier:
My device has become more and more laggy after updates, and it's crazy slow most of the times also the app. Decided to return to stock yesterday so I have backup all my apps with data with swift backup, but had to do many attempt because root refused to work.... I take out my backup. I return to stock roo by flashing on fastboot. After boot everything work perfect and I configure it... But when I restore successfully the apps with data afterwards I launch my app but there is no data and they start like fresh start of new app!!!!! Where are my data on the apps ?! I check the backup folder and there I see, that data files of backup are all sized 1Ko!!!! What a nightmare. But hopefully I kept backup folder from since last month. My overall advice to novice users : stay away from this firmware and use stock instead you will be happy. I think this Rom could be used for devlopper or experimental users.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
I can't really comment on the backup of your apps, but I have noticed a little lag too.

Installed the attached magisk Mods and it's flies now..

No lag at all.

Also install cloud flare DNS mod thingy. Seems to speed up internet connections. And Google sans mod.

My System does not Auto-Update if i choose "download" and then "install" the update.. If i want to update it manually do i have to clear cache and stuff?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] donjoe0:
Actually if I let it run long enough it slowly ramps up to double those numbers in both scenarios. -_- I think the rate is always better near the top end of the charge range and gets worse as it goes lower. In fact after I stop charging at 90% I will see it no move by even 1% for about 20 hours before it starts moving.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] donjoe0:
Wow, thanks for the hint! I installed the RAM management fixes and an Enable Doze for GMS one I found in there and my idle battery drain flatlined for like 6.5 hours. Before it was going down by about 0.5%/h doing nothing, on the "Power save" profile and with Aggressive Doze turned on in Greenify.

I still need to evaluate if this is affecting performance much, maybe I will need to disable Aggressive Doze or turn off some apps' battery optimization, but it looks like this is a more effective workaround than any of that other stuff discussed so far (WiFi manipulations like tethering on/off didn't do squat for me).

Oh and another thing I turned off trying to solve this was the RCS Service app, since it's supposed to be for rich-content messaging like video calls and I had been giving it no reason to take up as much battery as it was taking. Froze it with TiBa and it was gone from the top of the list in battery stats, though for not much total benefit. I may decide to bring this one back up.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
Did you try the mod to remove the swap ram? It makes quite a difference to multitasking and general. You can do this also using a kernel editor.

I have the 4gb ram version though. So not sure if that makes a difference with swap.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] donjoe0:
I don't have a problem with multitasking, I only wanted to solve battery drain. Plus I saw reports of the Swap Torpedo doing nothing for some people and making things worse for others, so I decided to skip that one.

I only installed the CloudFlare DNS, RAM fixes, and Enable Doze for GMS. In the meantime I've set the power profile back to Balanced and I'm still seeing about 0.2%/hour of drain in idle with no SIM. That looks good, at least for idle times. I'm still going to see excessive drain during actual usage, when GMS comes out of Doze like everything else, because the underlying bug in the kernel is not fixed, but at least idle will manifest like idle should.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Geo42:
I have encountered the same problem with fingerprints. I removed the pin I had before removing fingerprints and a message said that the fingerprints will be erased. But when I went into the menu of fingerprints to set new fingerprints it showed the old ones that didn't work but didn't let me delete them either. I can set new fingerprints I just can't delete the old ones it is like shadow fingerprints
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Armaty:
Exactly! this is what happening

And the worse thing is those fingerprints that are supposed to be deleted takes up space. For eg. If u have already set up 3 fingerprints and due to any reason u want to delete them, then after deleting u are left with only 2 as upper limit of Fingerprints is 5.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Geo42:
And this is the main reason I mentioned it as problem. Exactly as you said it. Maybe if we reinstall the update of the rom of 16 November over the existing it will erase them
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Geo42:
In the last update of 16 November

I have encountered a problem with fingerprints. I removed the pin I had before removing fingerprints and a message said that the fingerprints will be erased. But when I went into the menu of fingerprints to set new fingerprints it showed the old ones that didn't work but didn't let me delete them either. I can add new fingerprints I just can't delete the old ones because I did it that way. If I set a new fingerprint I can delete it. But the old ones stayed there as ghosts because I erased the pin without first erasing the fingerprints

I made a Magisk module to increase the headphone volume for this ROM (might work with others, but not tested).

With Magisk it should stay implemented, even between updates (which is why I created it).

I am really appreciate your effort and time for the rom. It's fantastic and efficient.

I have one suggestion to put forward

During update process instead of sending the whole package of 525 mb , is it possible to send the updating area only with less data consumption.

For me data not a matter.... It will be nice if it become small packets .....

Once again thanks for the efforts.....
