if this works for you, it does not mean that everyone else is doing well !!!! and yes there have written about this problem repeatedly
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
if you want it to be fixed do:

A: test if your issue still persists after a full factory reset (you are free to run a full backup with TWRP before doing so) exclude any third party apps such as magisk, xposed, viper4android after having run factory reset.

B: if the issue still persists. grab proper logs and open up an jira bug request.

After upgrading to 15.1, Yahoo weather provider stops working after every restart (cLock does not refresh the forecast when tapping on the refresh arrow). The only way to fix it is to reinstall it every time.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Uniposka:
I tried to clear data on both cLock and Yahoo weather provider, but that didn't make any difference.

I don't see any question mark, just the weather in the widget remains the same of some time in the past and cannot be refreshed, unless - as I said - I reinstall Yahoo.

Deleting cLock widget and adding it again does not help either. Same if I clear the cache partition.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Uniposka:
Good point, I thought it could actually work. But no, still the same.

I am thinking, could it be related to some file's permissions? So that maybe they get overwritten every time after a system restart? And then they get reset when I reinstall Yahoo weather provider, so that it works again...

Hey guys need help!!

Today I tried to flash that camera patch. So , booted to recovery , upon entering recovery it asked pattern to decrypt data (This never happened earlier ). So entered the pattern and it decrypted. I thought something is wrong so I booted to system. But Encryption Unsuccessful error came, it showed to reset phone ,so I reset it. Again upon booting to system that encryption unsuccessful error came. I changed the data to ext4 but again tht error came and again to f2fs but error still came. I tried different nightlies of 14.1 both on ext4 and f2fs but tht error still came. Then I restored from full stock backup. I tried both ext4 and f2fs but still encryption was unsuccessful. Also I wiped all system, cache, data , internal many times.

Plz help.!!
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] nihil39:
Thank you.

When I'm outside I prefer bluetooth for the freedom of movement, at home I stay with the cable. Let us know if it works in conversation. Even if it works, I don't think it will be merged in the next release, but I hope so.

funny thing I just discovered that while using BT the left and right speakers are swapped. it's not the case when using a 3.5mm headphone jack.

first I thought its an mistake in kuntao but turns out all my other phones (including Whyred which still runs stock software) has the same issue when using BT. then I thought it's my BT device but it play's correctly on PC.

So it's an Android BT stack issue err I mean "feature" :p

I can confirm, no swapped channels on bt or jack headphones.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
no sure what the cause is. I contacted Shure Technical support. they probably won't reply on a weekend.

it works without swapped channels an all other devices. avr receiver, PC, etc even tested a friend's iPhone. only on any android phone the channel's are swapped. no matter if stock ROM or lineage's. even on MIUI (whyred) the channel's are swapped. so something must be causing the swap on android.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
this is not a bug!

it's properly set like that. configuration is taken straight from Qualcomm platform code. if you don't like it.

use any kernel editor to change it to your liking.

but please don't blame the ROM after you changed the configuration and your CPU's won't enter deep sleep anymore or any other issues you will have related to CPU behavior.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
there were zero changes made related to camera in the latest nightly.

sounds to me like you need to clear the cache of that camera app.

maybe you flashed the gcam mod lib by highwaystar on the old build? flashing the latest full nightly then would have replaced that lib. but the cache in the app was still set to the patched lib. so just make sure you clear the cache.

highwaystar's gcam lib patch will make it into the nightly builds soon (v3 will be the one which made it into the finals) so flashing his fix in the future separately won't be necessary.

---------- Post added at 09:17 AM ---------- Previous post was at 09:14 AM ----------

clearly you are not a developer. else you would have known what to disable to make your CPU behavior changes persistent and not to get overridden.

it's not a bug if its intentional. like said you have the two previous mentioned choices left. have a nice wonderful weekend.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] danielcepa:
Its not the rom. Some app is keeping your device awake. Keep unimportant apps from autostarting and running in the background using Privacy Guard. Also check in developer options - running services - to see if any app runs in the background in real time, but is not actually needed.

Just had a 4 day battery run with 10 hours s.o.t. using the balanced profile. Every sync on, 4g, lots of gps and bluetooth audio. Deep sleep was about 75% in the end

TLDR: use basic android know-how to keep badly coded apps in check.

[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Taranis:
This is a bit OT, but... Am I the only one with file management issues on Lineage?

For example - moving files from internal storage to external very often is slow or impossible (error) in some file managers. I also had situation when I moved some files and then they re-appeared somehow, then after removal empty folders kept re-appearing... Copying files from MTP also takes really long, not always, but many times. I really don't like MTP transfer and Android's memory management. Maybe it's more secure, but I feel that old "Mount as storage" in old Androids were just faster...

No issues with microSD directly plugged to PC.

I also had issues when I saved something on phone and it was not visible on PC. In general I've had such different issues on multiple Android devices, but on Lineage's P2 it seems to be regular. I tried different PCs, Windows 10. Do anyone have the same issues?

I also have an issue with unreliable hotspot. It works 95% of times, but keeps disconnecting from the internet once 10-30 minutes. It works on the phone at that time, but don't work on PC. I need to re-connect to hotspot or reset it (or disable and enable LTE). I haven't had similar issues on my PC with other networks. Might be some incompatibility. Anyone experienced the same?

I'm not saying I have those issues constantly, but very often...
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
I constantly transfer files from internal storage to sdcard via Total Commander. Not once I run into an issue. I also use the Total Commander LAN plugin to connect to my NAS and also transfer filed back and fourth. I suggest you give TC a try, it's been around since decade's. Very reliable dev and app.

I used to have the described dropout issues on WiFi but that was with 14.1 and before mike rebased the kernel to latest Oreo CAF. Since then it's been rock stable. I do run a mesh WiFi network at home with three mesh nodes. The P2 roams seamless through the nodes. Your issue sounds like your nodes aren't properly running a handshake between the nodes and keep playing ping pong with the P2. The P2 will therefore keep switching between the nodes.

And I agree MTP is the worst protocol Microsoft has ever implemented. If you are lucky and are using Linux/Mac switch to AFT (Android-File-Transfer).

https://github.com/whoozle/android-file-transfer-linux

It's lightning speed fast compared to slow snake MTP.

[MENTION=3839575]mikeioannina[/MENTION] I asked the (telegram group) of P GSI how to get NTFS or exFat support on GSIs as it is supported in los but not after flashing GSI. They asked me to send you this.

"ask your dev to add CONFIG_NTFS_FS=y in their defconfig to add kernel support for it, it *might* fix NTFS for P GSI"

Can you please do the same for exFat too?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
probably won't happen. it's against the los charter. exfat support also only got added because it was available in the stock. I highly doubt NTFS support was available on stock.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] 5zan:
I request you to add exFat support at the least. Only reason I'm asking this is because the 4gb limit of vfat/fat32 is really annoying. exFat works on Los but not on any GSI flashed using this vendor.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] celoxocis:
the support for exfat is already present in the kernel. maybe your gsi image is missing the proper information about which driver is to be used? ever thought about that? there is more to it then just adding driver support in the kernel.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] 5zan:
Oh ok. My bad. I just said this coz I've tried around 5-6 GSIs and exFat didn't work in any of them.
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] Taranis:
Indeed, I have tried Solid Explorer now and the transfer speed seem to be great, it even has transfer speed graph/chart (like in Windows 8+). No errors for now. I wonder if it will fix weird issues with re-appearing empty folders... We'll see, maybe my issue was too old apps (like OI File Manager).

About WiFi - I probably wrote it not-so-clear: I've meant "create AP" feature in Android (sharing 3G/LTE via WiFi). It works every time, but Windows keep reporting every 10-30 minutes about "Connected to AP, but no internet connection". I've got that issue in 14.1 too and I'm pretty sure it's not my PCs fault as they're going rock stable on another APs (I use them daily in my work) and on P2 this issue is recurrent. It is very annoying, because I work sometimes outside and use my P2 as AP. I wonder if it's related to changing BTS station or fluctuating LTE signal? (although I'm getting this issue sitting in the same place)

BTW, Normal WiFi connection is rock stable on P2 since stock on my side. I haven't had any issues with WiFi. Thanks for your contribution in P2 support!

--

I'm going to 14.1 for a month or two. 15.1 battery is very similar like in 14.1, but I feel Oreo is not yet polished. For example - Google Pay screen after payment appears like few seconds later or never on Oreo. I also like Nougat battery management more. Oreo works as smooth as Nougat mostly, but sometimes when I open some apps, I need to wait a few seconds (unusually). Just like my CPU would be overloaded. TWRP and Magisk are not yet marked as 'stable' too, Substratum works in a different way than on Nougat... It's too early for me :D But I appreciate your work and switch to Oreo soon! I've never seen such great developers and user group on my last devices (maybe it's because it's popular model in India?).
