[LG V30 Questions & Answers] dp102288:
Hello all. I have a H932, rooted, magisk 27 (no zygisk). I do not have any xposed or such. On stock Tmobile Pie. I am running Lovins Stock Android 9.0 Optimization Magisk mod. I am running Goodev's Volume Booster. And one of the equalizer mods, sorry I don't remember exactly but if relavent I can figure it out & post. I can't think of anything else relevant.

I cannot get call recording to work. I was using rooted stock Oreo until about 1 month ago, for several years & had call recording working I had the Anxious mod & xposed & magisk & lots of stuff. Since upgrading to Pie I am not having luck. I upgraded through TWRP from the Pie files directly from XDA. No issues day to day. Calls, texts, data, wifi, volte all work fine.

I will list everything I have tried so far. Not in order though if it matters, because I cannot remember what order I did things in.

I tried both the zips in [Mod] (Closed) Call Recording & Volume Button Answer mod & New Call UI (Pie & Oreo) (https://xdaforums.com/t/mod-closed-...tton-answer-mod-new-call-ui-pie-oreo.3951967/). I flashed the zips attached from post #1 through TWRP, US998 Pie & v30b Pie, without success. Post #89 in that thread mentioned "new US988"" was working on their H932, but I could not find that exact file from the original post as the link is dead. After both zips did not work, I extracted them & manually copied the apks to the respective directories in TWRP file manager & changed the permissions as required. Still no luck.

I also tried Enable native call recording on LG V30 stock Oreo 8.0 [root] (https://xdaforums.com/t/enable-native-call-recording-on-lg-v30-stock-oreo-8-0-root.3869260/) without success. Even though this was for Oreo, I tried it anyway hoping, but no. I also extracted, moved the apk, changed permissions as above, but still without luck.

I will mention I DO have the record button during a call, after the first set of zips. Pressing record indicates it is being recorded (it highlights). But after ending the call, no audio files were saved anywhere I can find in my file explorer, or in the "HD Audio Recorder" app. Same if I end the recording prior to ending the call. No files.

I then tried BCR (Basic Call recorder). And no matter what version I tried from GitHub (I went through several posted discussions & tried debug versions the developer had posted as well), no luck. Various file formats & bitrates also no luck. With BCR I had it set to auto record, & at the start of a call it would indicate recording in progress (I don't remember the exact wording), but then show a failure notification. I have attached a screenshot. But BCR says:

Failed to record call

The recording failed in an internal Android component (android.media.AudioRecord.native_get_buffer_size_in_frames). This device or firmware might not support call recording.

Unable to retrievre AudioRecord pointer for frameCount()

So I believe that even the native LG call recorder cannot record because something bigger is missing/failing.

I also came across (Tutorial) Stock LG Rom (v30 or Other) Call Recording and Other Mods (https://xdaforums.com/t/tutorial-stock-lg-rom-v30-or-other-call-recording-and-other-mods.4077029/) but I have zero idea how to decompile apks.

So my question is, is anyone running a stock Pie H932 with working call recording? If yes, what apks / zips did you use to get it working?

I heavily searched the forums using google with site:xdaforums.com because I can't figure out with the forum search how to limit to just V30 threads. I am not much of a forum poster so I don't know how to embed links & such. But any direction to get working call recording would be greatly appreciated. I am only interested in stock Pie because I am on Tmobile & need working VoLte. I want Lineage but can't.

Thanks to anyone who helps!
