You try Tota Call Recorder.It works for me for all my devices since a long time.It has plenty of customization too.
[Xiaomi Mi 10 Questions & Answers] sri4xda:
You can sign up for beta app of google phone. It has call recording feature in default dialer itself.

However it is pretty bland, not for a lot of customisation.

It announces we are recording call which is a blocker for people who want to secretly record.

As you know, secretly recording is crime according to privacy laws in many countries.
[Xiaomi Mi 10 Questions & Answers] pnsdhrn:
Please give the link for the beta version of Google Phone apk.I can't see it in Playstore.
[Xiaomi Mi 10 Questions & Answers] sri4xda:
Search for Phone app in Play Store.

Scroll down to find beta section.

You see a button 'join' (in my screenshot it is showing as leave as I have already joined)

A new update will be available in Play store after few mins.

only problem with google phone is that u wont get any notification for mist call's thats why i dont use it anymore
[Xiaomi Mi 10 Questions & Answers] sri4xda:
Strange. I get missed call notification correctly. Anyway google phone is the default dialer in Mi 10 global and many are using the default dialer already as third parrty dialers run into issues here and there.

I just flashed my Mi9 with xiaomi.eu ROM miui12 and it has Mi contacts and dialer as default. But I have seen on some videos that for Mi 10 xiaomi.eu uses stock Google dialer and contacts, is that true?

no they use standart contact an phone but u can install gapps then u will have gphone an message

i found a way to get missed called notification now on gphone

so that dailer i use now

I don't like Gapps that's why I installed xiaomi.eu ROM on my device. But it's good that it let's users to choose unlike the Global ROM.

[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cheetah2k:
I have a SM-G9880 BRI (taiwan) version and using in Australia. I have all the 3G/4G options but I'm unable to select any 5G - even though the phone is a 5G phone. I know my carrier does not use 5G in my area at this time, so is it not showing any 5G options because 5G is unsupported? Is it SIM related or would it be because I have a BRI (taiwan) CSC? I know others in Australia with SM-G9880 TGY versions using 5G (on different carrier) and they have 5G options... Just confused whether the 5G options are disabled because of the SIM, or because of the CSC??? :confused:

If its CSC related, I might try Samkey to change the CSC to TGY...
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] west2cool:
5G has not been activated on BRI csc as there is no 5G in Taiwan yet. Its best changing to TGY however you will only get 5G using sim tray 2 (meaning you will not be able to use SD card at the moment).

[MENTION=414798]

[MENTION=1000401]cheetah2k[/MENTION]

Is changing to hk firmware version using Samkey what you ended up doing? Was it easy.... I am not Tech savvy. I got this phone from eBay seller who was showing in Sydney but the phone ended up coming from Taiwan
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cheetah2k:
This is the method I used (creds to user jabreel.torrin in the S10 forums. I did modify this though to suit the S20U) - You don't need to Odin flash the TGY firmware as its identical to the BRI - only CSC needs to change from BRI to TGY :good:

1. Buy 3 credits (can't buy 2) from this seller that on ebay that I used : https://www.ebay.com.au/itm/SamKey-Code-Reader-3-Credits-UNLOCK-Fast-Service/324110503100?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2648

2. After buying the Samkey credits you will be emailed the username and password for the Samkey App (you need this!)

3. Enable developer options on your phone: Settings > About phone > Software Information > Tap "build number" 8 times or until you see a pop-up message that says "Developer mode has been enabled".

4. Turn on USB debugging on your phone: Settings > Developer options > USB debugging > Allow USB Debugging > Tap "OK"

5. Go to www.samkey.org and download the Samsung USB drivers (if you havent installed any samsung software on the PC already) and the Samkey application

6. Install the drivers first, and then install Samkey application on your computer > Connect your phone to your computer with a usb cable > Login with the username/password you received from the ebay seller.

7. Click the "Read Info ADB" button to make sure your phone has been accepted by ADB

8. Insert the CSC code you want into the "Change CSC (Buyer)" field > With the BRI SM-G9880 you want to insert TGY (where is shows PHN in the pic below)

9. Click the "Change CSC" button > Confirm that you want to spend 1 or 2 credits (for me it was 1, but some report 2 used).

Let the application do it's work after which it will reboot and then you're good to go. :fingers-crossed:

For me it was seamless and worked so easy. Zero complaints. 5 min later I had a TGY phone - and I have reserve credits for the next Samsung phone I need to change Hope this helps guys!

OMG I can't thank you enough for the detailed breakdown. You just saved me alot of headache. I will try it tonight and let you know how I go.

Thank you again
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cheetah2k:
No probs mate, dont forget to click thanks on my tutorial if it goes to plan :)

Now all i need is to get a Telstra sim (as theres coverage in my area) and then can use the Band N78 5G :laugh:
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Mittesh:
It's worked!!!! And it was super easy. Is it true that only Sim 2 works for 5G? I can see the 5G option on Sim 1 but haven't seen it connect. Not sure if it's cuz of no coverage or issue with phone Sim trays
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] pafc66:
I did this but I wouldn't recommend changing to TGY firmware as a Telstra user. You don't get band 28 700mhz carrier aggregation. So no 4gx . For some reason I only get it with the Taiwan CSC but you miss out on 5g , to me that is less of a big deal than no 700mhz band 28 pairing with other bands for 4gx. In other words you'll get 4g+ less with Hong Kong firmware but you'll get 5g.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Mittesh:
If there a way to get both the options?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] pafc66:
Not at the moment.

Best to stay on Taiwan firmware as they appear to have 700mhz band 28 carrier aggregation and wait till they add the 5g option when their local networks commence it later this year. I'm told it's this time when Samsung will push a update to enable 5g capabilities to Taiwan firmware.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Mittesh:
Is there an option to go back to BRI Taiwan firmware once they enable 5G with the option of have both these bands at the stage?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] pafc66:
Yeah, you'll just have to download the Taiwan firmware when they get that update and change the CSC with samkey back to BRI
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Mittesh:
If you change your CSC, will your next firmware update me for that country. Like I have just changed from BRI to TGY... Will be next update automatically be the Hong Kong version of firmware? Or will it go back to BRI?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] pafc66:
You won't get a over the air update if you CSC doesn't match your firmware. You'll have to change the CSC to match your firmware. So change to BRI Taiwan CSC to receive the Taiwan update and vise versa if you have the Hong Kong firmware
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Mittesh:
So my phone was BRI Taiwan version and all I did was buy the Samkey credits and change CSC to TGY to enable 5G. Does that mean no more updates for me until I change it back to Taiwan?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cheetah2k:
Band 28 is available in the carrier band selection options FYI :good::good:
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] pafc66:
I'm aware of that, it's available.. however it doesn't support Carrier aggregation for Telstra 4gx which is when band 28 pairs with Telstras regular band 1 or band 3 4g. So you'll get band 28 but only band 28 by itself which is slow.

The Taiwan firmware does support those carrier aggregation combos though for some reason.

---------- Post added at 01:03 PM ---------- Previous post was at 01:01 PM ----------

Yep. Unless you load the Hong Kong firmware on it as well with TGY CSC .

Hello Everyone,

I have the same Problem.

In Austria (Not Australia :)) my Provider supports Band 3, 7 and 20.

With my sm-g9880 i had no carrier agreggation with csc BRI. So i changed my csc with Samkey to TGY. Now i have caller ID, 5g and carrier agreggation.

But only with Band 3 and Band 7.

does have anyone an idea to force carrier agreggation with Band 20 and the other Bands?

Thanks
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cheetah2k:
You'll need to flash the TGY firmware using Odin. I installed and earlier version of TGY on my BRI S20U last night, and it immediately picked up the ATCT update and installed.

Its a shame Samsung make it hard for those of us who want SD865... I seem to have no issues with carrier aggregation (4G+) on vodafone with the TGY firmware.. All running smooth here. 4G+ carrier aggregated downloads sitting around 190mbps which is about right in my area in Brisbane, Australia :good:
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Mittesh:
Thanks for the heads up. I noticed my software version is already showing ATCT after changing the CSC to TGY. Does it still mean I still need to flash TGY firmware? This is my first time doing any of this sort of changes.. Is there an easy "how to" website you can point me to to guide me to do this easily. Will it wipe the device clean back to factory?

Everything on mine seems to be working fine. Just 5G is super slow and I guess I am worried that I won't be getting anymore updates due to changing CSC only.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] pafc66:
Just load BRI Taiwan firmware back with Odin. Simple.

My 5g speeds were like 800mbs with tgy firmware. It was my 4g speeds that were slow. I'm with Telstra
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] ChromeFR:
Are you guys sure you won't recieve OTA when phone is changed from BRI to TGY? I just changed my CSC from BRI->TGY and immediately I recieved an update which I didn't see on the BRI CSC.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] ChromeFR:
I think you are not right, but correct me if I am wrong. I think de TGY and BRI share the same firmware. So if you only change the CSC with Samkey you'll be able to recieve OTA updates. Like I wrote before I immediatly recieved an OTA update after changing the CSC from BRI to TGY. But maybe I am missing something here, new in this.

You'll not receive fw if you have changed CSC from BRI to TGY, but not odin flashed the TGY fw. if you're still on BRI fw but with TGY CSC, technically you shouldn't get the current ATE5 update

[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] sergmarin:
You can do it only via Samkey (paid).
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] ChromeFR:
I really think that what you are saying is incorrect, there is no need to update the firmware in this specific case with TGY and BRI S20+'s. Let me illustrate this by a screenshot of the downloaded firmwares (both most recent versions) from Sammobile:

Look at the file sizes, the filenames, everything is 100% identical. The only difference is that de TGY CSC triggers the the baseband ATE5 update. So why should we flash an identical firmware after a CSC change BRI->TGY with Samkey?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] cturbos:

Has anyone managed to get 5g working on Taiwan firmware yet?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] west2cool:
Mate there is no 5G in Taiwan so Samsung has not activated 5G on the Taiwan firmware yet. You have to change your csc to TGY (HK) to get 5G.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] pafc66:
Yeah I'm aware of that but my 4g speeds are slow on that CSC and modem. No carrier aggregation so no Telstra 4gx :(. Whereas in the Taiwan firmware there is for some reason.

I thought Samsung would still allow 5g to be selected if the hardware is there.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] west2cool:
Samsung knows exactly what they are doing. They have only recently activated 5G on a few European T-Mobile firmware.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] pafc66:
So they know that 5g only works in the second Sim slot? That's dumb then
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] sergmarin:
Nothing like that, 5g works in any slot, but only in one of the two. You can select any SIM card.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] lovers74:
He is right, 5g works only in sim 2 slot, even if it is showing in the option that sim 1 has 5g it never connects. Also, after updating to latest firmware I dont get 5g if both sims are activated, I have to disable sim 1 in order to get 5g on sim2 ! Obviously Samsung know what they're doing.

Hi all,

I also got a BRI model, flashed the CHC-firmware via Odin to the phone and back to TGY/BRI firmware, now, 5G icon is available, and the following is stated in the phone info:

TGY/TGY, TGY/BRI

What does this mean? Do I now have TGY version or BRI version?

Problem is that I only get the 5G icon on a non-solid ground; however, the 5G icon on solid ground does never appear ;-(...

Do I still need to change the CSC with the method described above?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] sergmarin:

[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] protonic_1:
ok, that's interesting ;).

For anybody who likes to try out as well, here is how I managed to do it:

1.) flashed TGY/BRI firmware (may) with Odin

2.) flashed CHC firmware (may) with Odin

3.) flashed TGY/BRI firmware again with Odin

but why do I still see "BRI" in the Codeline? (TGY/TGY, TGY/BRI )
