You can't install lineageos without recovery. Which means your device is rooted. You could easily install Magisk.
Not rooted... Impossible.

I install Lineage OS from here.


In AIDA64 writes that Android is not rooted.

You unlocked the device then used custom LineageOS recovery. So now the device is rooted. All you need is to root the Rom. You can easely root it with Magisk apk sideloading or Lygisk - it's written in the instructions. Then you can try using call recorder with root permissions. Lets hope it will work better.
Cheers.

Hi mate,

So last version was working fine till now and today I updated to the latest version. Only issue is that after reboot, it doesn't start automatically and I don't have any notification for it in my status bar. I have to run it manually and then change recording off-on to have the notification again.

I have K20 Pro, ancient rom (custom Android 12 rom).

Any ideas?

Thanks.

Edit:
Ignore it please, looks like a one time issue. Started fine on next start.

Hi,

My phone is Samsung Galaxy M02s. Running on Android 12, One UI Core Verison 4.1. Not rooted and have no plan to root. After updating from Android 11 to 12, built-in automatic call recording is not working, I mean there is no sound just audio file.

Will your app v.3.5.1 can solve this problem? Please, suggest me something.

Rooting your device is your only solution my man.

If you didn't point it out, I wouldn't go to take a look of mine! You are not alone, I am on A13 with Google Pixel Pro, since updated to 2.1.1, all of my calls (both in and out all) indicated that they are "failed to upload".

@skvalex
This is a serious issue as people may delete their recorded calls on the phone as they believe those would have uploaded to the cloud.

@skvalex

Do you see the "Failed to Upload" issue with your latest version 2.1.1? Any possibility to get a fix for it? Otherwise, may have to do something manually by users.

    There should be a Wiki where people can list phones they tried and the result. This thread is just too extensive!
    Right on. I'd love this. When I shop for a new phone, "will Call Recorder work on this one?" is the only real question I ever ask.

    Good morning.
    Yesterday I bought the application for a family member and we have the following problem in your samsung galaxy s22 +

    The recordings do well (something under the volume but acceptable) but the problem comes when sharing calls (by email, whatsapp, telegram ...) that are almost inaudible. Do you know how to solve the problem when sharing files?

    Regards
    When you share a file you send a copy. i think therefore the problem could be related to the mobile phone or pc that receives the file. did you control audio settings?

    Welp, after about six years of never failing to record a call on my Pixel, I just lost a very important conversation on my new, rooted Pixel 3a. Call Recorder seemed to record, but on playback, just a series of feckless clicks and distortion. I'm using Root CAF and Wav, but I've tried other settings to no effect. Some calls record fine. Others produce nothing but garble. Unless someone has an idea of what might be going wrong, looks like I'm back to shopping for a new phone.
    I switched my recording method from ROOT CAF to uplink+downlink and that seems to have fixed it. For what it's worth.

    I've encountered very strange issue. I've installed 3.5.2 on fresh Google Pixel 4a/LineageOS 19 and was unable to upload recordings. While app creates necessary remote directories, the file upload itself fails with 'upload failed message'. However, if I reinstall the app, upload begins to work.

    I tried factory reset and the issue repeats. Not sure, how reinstall helps though.
    Sorry for the delay. Check the attached version please

    Sorry, skvalex, you have reason.

    Here the screenshots. Frist during call. Second just after hang out.

    Thanks in advance.
    It seems like built-in call recording is missing. Does the app ask you to grant ADB permission on the main screen?

    Call Recorder - SKVALEX
    version: 3.5.3

    Last update of the app in this post: 22.11.2022

    Download

    Purchase over PayPal/AliPay via website: https://callrecorder.skvalex.com/purchase

    Description:
    Call Recorder - SKVALEX is intended for automatic call recording. The app provides functionality to record both sides on devices with such support. But some devices don't have 2-way call recording support, or have issues with Bluetooth recording.

    Also, the app provides wide functionality to manage recordings:
    - Search recordings
    - Conversion from one format to another (e.g WAV to FLAC/OPUS/MP3/etc.)
    - Adding notes to recorded files
    - In-call control button while call recording: you can easily start/stop recording during a call
    - Enter to the app using password (or fingerprint)
    - Auto clean-up - automatically removes old recordings according to rules set by you. Starred recordings ignored.
    - Exceptions: you may set up phone numbers, contacts or groups for specific actions, like always record or do not
    - Filename template: you can easily change structure of created files
    - Cloud backup support
    - Playback recording over main speaker or handset speaker
    - Access recording from within contact info
    - Call confirm: the app will ask you whether you want to make a call or not
    - After call actions dialog: the app will ask what to do with a recorded call
    - Vibrate on call start/end

    If you want to get option "start recording on answer" work without root, then you'll need to grant READ_LOGS permission to the app via adb:
    Code:
    adb shell pm grant org.skvalex.cr android.permission.READ_LOGS
    Note, that you may need to manually enable logger in engineering menu (or anywhere else where your device manufacturer disabled it). Don't ask questions "how to enable logger" here, you better google it or ask it in forums about your specific device.

    Hi
    Today I got the attached email from Google. The app is banned from the Play Store. I sent appeal, waiting a reply from Google. Hope they'll allow to reinstate the app. I think the issue was because of linking to AlsaMixer: https://github.com/skvalex/alsamixer

    If you like to purchase the app, you can do it via the site: https://callrecorder.skvalex.com/purchase?hl=en

    P.S. If Google won't reinstate the app I'll do my best to keep licenses for people who already purchased the app.

    P.P.S. You can install apk from the OP. The app should be able to verify the license.

    EDIT:

    Hi Skvalex,

    Let us know if you're still around and if you have any news about reinstating the app in the Google Play.

    Google won't reinstate the app.
    But I still can publish the app to the Play Store as a new one. So I'm working on it now. It gonna be a free trial app + another app to unlock the full version. I'll create an apk which will unlock the full version for people who have already purchased the app. So they won't have to pay for the app again. Also, I have to remove all root functions from the app which gonna be on the Play Store. So another apk with root functions will be on the xda.

    I hope I release the new version till the end of August. Magisk 13 will also be supported.

    1. Uploaded beta version to the Play Store today: https://play.google.com/store/apps/details?id=org.skvalex.cr
    2. I've attached the Unlocker for people who purchased the app on the Play Store before.
    3. I will upload Root module for this version tomorrow. Also, Unlocker from the site won't activate this version. I'll upload the new unlocker tomorrow as well.

    edit: You can now update purchase status in the client area by entering your transaction ID: https://callrecorder.skvalex.com/clientarea and download Unlocker from there.
