Hi,
Has anyone managed to get call recording to work on any of the S20 phones?

Many of the call recording apps don't work, but I read somewhere that if you root the phone you can get it to record.

Another website mentions changing the CSC to one of the countries that allow call recording, for example Thailand. Apparently there is a built-in recorder in those countries' S20 phones.

Is there any way to get it to record?

Thanks!

S20+ in Thailand does have built-in voice recorder. Works as intended.

Can we change the CSC to enable this, by installing a Thai Sim or updating to a specific Firmware?

I ordered my S20+ from Vodafone Germany and also ordered a Thai Travel Sim to try this since it apparently worked on other Galaxy Phones in the past.

I hope I can configure the Phone without a Sim to order the Galaxy Buds+ (free for Preorders but has to be ordered through an App on the Phone, so I suspect it must know it's German at this stage) and change to Thai after before it gets 'locked'.

Call Recording is a crucial feature for me.

Skvalex call recorder has a guide in his website how to do it. But you need to have a Thai SIM.

but sadly once u change your CSC to a different country, for example thailand, you'll be gifted with thai related apps.. on my previous phone i just edit the CSC to enable native android call recording.

but you will need root for this.

Exactly, but you gain some and you loose some. If someone preffer call recording, main option you loose is Samsung Pay, other apps work fine. It's just the preferences. I would like to have call recording, i can secrifice Samsung Pay :D

Rooting phone is different ball game alltogether. I dont think rooting is worth enough. you dont acheive mush with rooting now a days, (Just my openion)

But i would really look forward to change CSC on my phone, and waiting eagerly for a work around

So I now have my phone (S20+ 5G - SM-G986B) and was looking to change the CSC...

Out of the Box, the Thai Sim did little to nothing. Obviously Samsung recognized the region, since Ts&Cs / Samsung Member confirmation was in Thai (even though I set it to my region), but nothing as far as CSC or Call Recording are concerned.

Did I see correctly that there isn't even a THL Firmware for this model?

Any suggestions?

Thanks!

I just recieved my s20+. I think that Thailand sim didn't work because only csc on a phone is a csc country you purchased phone. No multi rom. Hope it will change when they realise multi rom.

U can use call recorder acr from the playstore in de meantime. :good:

Grtz

Doesn't work for me. It does record calls, but apparently converts to a wrong Sample Rate as it plays back multiple times (5.5) faster than it was recorded.

Technically the released Multi-Roms: There's definitely an OXM including THL for SM-G985F (S20+ 4G) - just not for the 5G model. Maybe I should have saved €100 for the 5G that I can't use in my Region anyway. Thought I would future-proof. :(
 
All "international exynos versions have call recording built-in into the software. To enable it, the right flag should be enabled in the cscfeature.xml file (you need root for that, unencrypt the file, modify it and overwrite it back again).
However I'm not sure if you can write to that product partition anymore, on the S20s (we cannot write to system directly anymore). Worst case scenario, a Magisk module could do it.
I'll try it now on my S20+ 5G (intl) and report back ??

So did you manage to root it already? :good:

Please keep my posted, I am eagerly waiting for it.

Currently on a rooted Huawei P20 Pro, I have my S20+ 5G laying on my desk unused, since I assume I'll need to wipe and flash it anyway (either during bootloader unlock or CSC Change) to achieve recording.

Recording truly is a showstopper / knock-out criteria to me.
If I cannot do it, I will have to return the phone.

Frankly, the improvements over my current phone are way too minor to justify the price of admission anyway.

    my friend do you find any solution?

    Here is what I found so far:
    • ACR Pro 33.1 unchained - records but playback speed is wrong (too fast)
    • Boldbeast v13.1 - working OK, but only for 30s in free version, unless you start recording manually by pressing the Record button.
    • Cube ACR v2.2.176 - working OK, no need to buy premium (I recommend this app). Download .apk directly from https://cubeacr.app/

    My phone is Samsung Galaxy S20+ 4G, Australian market, bought directly from Samsung, everything stock, no root.
    Model SM-G985F, Build G985FXXU1ATBK.

    To make Cube ACR work, I did the following:
    Go to Cube ACR Settings -> Recording settings -> Phone recording audio source -> choose "voice recognition (software)".
    Scroll down and turn on "Normalize Speed" setting.
    Go back, Settings -> Miscellaneous -> scroll down all the way -> press each one of the four buttons and turn on accessibility settings, turn off battery optimization, and so on...

    That's it, you should be all good. Try it and see if it records and plays back properly.

    I have samsung s20 plus 5g SM-G9860, Base band -> G9860ZCU2ATFF, CSC -> BRI, Can i put firmware Thailand?

    I think you can choose only: China (Open China) (CHC), Hong Kong (TGY), Taiwan (BRI).
    Don't think you got THI firmware available. Sorry.
