Suppose the phone is not updated to the recent 2 or 3 builds. If I want to update the next latest build, is it necessary to update all the recent builds before the latest update, or the next latest build can be updated directly?

And set it to 909kbps, then the option is not set if I exit and return. Really annoying as this setting helps my car audio!

That setting is not a default setting. It is part of the developer section. What means that you normally don't have the possibility to use it. Therefore I recommend not to use it.

I've been away for a while (busy with work and real life stuff), but I'm slowly getting back to lineage dev. I've been using an updated kernel since a couple months, which I can't push because of the f2fs breakage. I don't notice the wifi/data battery drain you are talking about, maybe it was fixed in some kernel update. I will try to merge newest kernel updates without touching f2fs so we can get wider testing on next builds.

I'm aware of the low earpiece issue, I've tried a few things so far with no luck. I need to trace back and find when it started happening so I can know what causes it. There's also another issue where camera doesn't work if you delay entering decryption PIN or when boot takes longer to finish, will test some possible solution for that as well.

Since lineage 16.0 is getting close to be ready for initial release, I will soon start pushing the required commits for 16.0 kuntao on gerrit. I have some nice [redacted] plans too so stay tuned :)

Thank you for the update. I still have the WiFi data issue.

I have the Chinese version, so maybe it's something to do with that, but it's still happening.

Two screen shots before turning WiFi off and after turning off. Not touched the phone. Stock version of 15.1.

I'm used to just toggling hotspot on and off again now so it's all good. Possible that other people have the issue without realising and not getting the battery performance they expect. I usually get three days, which is amazing.

Thanks for your help and good look with pie.

Hi. I had an idea that the issue might be with the WiFi auto turn on. I have it enabled, but I just disabled it and didn't get the wake lock issue.

Do you use 'Turn WiFi on automatically' function?

If you do, would you mind turning it off and seeing if you have the wake lock issue?

If this fixes the issue I'll record some logs and update the jira as it is repeatable.

[MENTION=3839575]mikeioannina[/MENTION], this question is phone related and not strictly related to LOS. Lenovo P2 has always had a mic audio issue, I think you know this: while recording thru audio recorder or whatsapp/telegram, a sort of noise suppressor kicks in after a second. The recording turns into a sort of watery thing that is really annoying. This issue came from the stock rom and it's present on custom rom, too. I dunno how audio works, if it's kernel or driver related. Do you think is there any way to work on it?

Thanks!

Aptx is working

Hi,

I used to have the same problem, but now it's working fine.

What i have done:

- first thing is that i have latest AOSP, but i think this is lineage based,

- install magisk, then install Aptx module with magisk,

- i use wh-H9000n headphones. I have installed "headphone" apk for my headphone. Go to settings in apk and switch from stability connection to quality. Then go to dev. opt. and switch bluetooth to aptx.

You have to use some headphones compatible with aptx.

Good luck !

APTX for Lenovo P2

[MENTION=1140170]nilsk123[/MENTION] [MENTION=8346215]Lyceus[/MENTION]

About APTX. I've the same problem. I can setup APTX or APTX HD in the developer options but after I connect my APTX Headphones to the phone the ystem switches back to AAC, 44kHz, Stereo

[MENTION=7368799]Tadiadi[/MENTION] Which aptx did you use? This One? Did you install it manually or through Magisk

EDIT: OK. I can confirm that the TWRP flashable.zip from thread mentioned above is working. It sets this values autoamtically for my headphones to 24 bit, 48kHz, APTX-HD Audio and my headphones confirm that they are connected via ATPX HD. I have to confess I can not distignuish between AAC and APTX-HD Audio while listing to the music.

Where can we tell the developers that the APTX implementation for the P2 in lineage os is vaulty or is it a licence issue?

I've got some issues with this ROM (lineage-15.1-20181030-nightly-kuntao-signed.zip ):

a) Fingerprint button should ignore the touch hold gesture if the button is pressed. Is there a way to acitvate the correct behaviour? - It has three working modes 1. touch, 2. press, 3. touch hold to control 1.back, 2. home screen and 3. "taks manager". But somehow press and hold are mixed up in this rom. If I press and release the button and then hold the finger to long on the unpressed button the "task manager" pops up. I don't have this behaviour on the stock rom. And yes, it is the touch gesture that creates this issue. I tried to press with a not-like-finger-pen and the "taks manager" doesn't pop up.

b) WIFI off while screen off option missing. It is always on. Is it only in my phone? This option is missing.

c) Auto brightness has jumping values in low light situations with low auto brightness value. The screen goes from low illumination to very dark illumination immediatley without some values in between. Is there a way to restore the stock rom values? I tried Xposed Gravity box where you can change the auto brightness values. This changes the brightness levels but it doesn't change the jumping in low value/light area. --> How to test: stay in a dark room, activate autobrightness, slowly move the slider from very bright to dark and back.

d) Adjust LED Brightness. Is there a way to adjust the LED brightness/color? solved. Could be found in Settings --> Apps & Notifications --> Notifications --> Battery light and and Notification Light

e) The icon doesn't show that fast chargeing is active. Fast chargeing itself is working.

f) APTX not working. As described here solved. APTX has to be installed manually.

A) only behaves that way with the stock ROM. All other ROMs seem to behave where pressing the home button doesn't block the touch. You get used to it and it's fine.

C) not had that issue

D) yes, see screen shots

Here's a nice little tip to make your device super smooth.

You'll need root

Download the below two apps

https://play.google.com/store/apps/details?id=com.fifthelement.trimmer

Run the trimmer app including system (says you don't need it, but it removed 2.5gb on my device and does so after every reboot).

https://play.google.com/store/apps/details?id=eu.thedarken.sdm

Run the quick access options in SD Maid, specifically the data base one.

And that's it. Seems to cut all lag out and make the device super smooth.

Hey what about that trim application you mentioned above. Is it safe? What does it do actually?
[Lenovo P2 ROMs, Kernels, Recoveries, & Other Devel] andyscuff:
This is from the app.. it's safe as far as I know.

Trimmer is a user-friendly implementation of fstrim Linux utility.

Almost all Android devices use NAND chips for data storage. Because of how NAND chips work, they may become significantly slow after some time. Trimming would help to restore NAND Chips performance to their initial value. Although Android 4.3+ supports trim natively, users have no control over this process and Android doesnt trim the storage as much as it is supposed to do, which results in slow storage performance and thus laggy devies. Trimmer enables you to trim your device manually if you feel it has become laggy.

Trimmer incorporates a well-known fstrim utility which is a part of Linux kernel tools. This utility trims memory devices which support TRIM operation.

This application is free and ad-free, Please consider rating it 5 stars if it helped you :)
