If you saw one of my posts before, you'll know what I'm talking about. Otherwise, please read that first.

The UI itself gained some moderate traction outside our community, and I'll start with the basic facts:

• The sub logged into a Samsung child account.
• I logged him out and saw the clipboard being cleared before I brought it up, so he doesn't know my auto-generated password, and did so to unlock the developer options so he can test someone else's app. (Pronouns assumed from the YouTube profile linked to one of his other Reddit accounts.)
• While the app was running, the device factory reset itself and was locked. Sometimes, hardware-based memory integrity checks fail and cause this.
• It is currently unknown whether I was the one who reset the device or not. (Also, if your voice assistant is reading out this post to you, please stay until the end because there's a question about that.)
• There may be backups elsewhere, but I could not find any in Samsung Cloud.

Possible reasons against me resetting:

• I logged out before this happened
• I could not find a menu for mobile devices in the Samsung SmartThings app, referring to the bullet point at the bottom
• When I set my old Samsung phone to Lost Mode several weeks after logging out and deregistering the device, the moment it synced up, the device completely disappeared as if I never owned it. (This phone was bought in a rush to avoid me from getting bored on long bus rides, and is listed as "Android - Others" in the compatibility table. Because it uses Knox Core, Safe Mode cannot be disabled this way.)

Possible reasons in favour of me resetting:

• Due to server-side caching, even after clearing the browser cache, SmartThings Find was showing the device for a day afterward, until the device-finding network synced up. I wouldn't be surprised if a bug allowed reset commands to be sent after a logout.
• I authenticated with my 2-Step Verification code to view the device information in SmartThings Find within the last several minutes of hitting the reset button. This authentication is done before I type my password and click "ERASE," according to recent YouTube video tutorials on how to reset a Samsung device on SmartThings defined, based on the publishing date. However, my password automatically filled in, so I may not have been thinking clearly.
• I saw the phone had the Samsung SmartThings app installed.
• I logged into that account on the SmartThings app and the device count blinked to one and then back to zero. I'm using a different Android manufacturer; the app works there as well. I really hope it didn't "delete" that when counting back to zero and sent an erase command.

Based on this information and weighing the arguments carefully, do you believe I reset it or not, and why?

P.S.: By the way, I found an easy way to determine the region of a Samsung device, even when the model code doesn't give you a clue: create a Samsung account on that device and go to the email inbox to find the message thanking you for registering your product. The last three characters of the really long model number are your Country Specific Code and, along with additional checks, determine whether the child account is allowed to log in or not. Funny enough, my old phone appears to have been imported from Guatemala, and it was carrier unlocked from the start.

Hello!

While you don't need a physical Samsung device to participate here, it may come in handy. I welcome all kinds of people, including:

• Those with real Samsung devices
  • Bonus points if you can plug it into a computer
  • Extra convenience for people and devices purchased in the United States, although this is not necessary (edit: a CSC change is likely to be required for people outside the U.S., unless the Remote Test Lab from "created the child accounts" chose a random region; see below)
• Technically savvy people. Including, but not limited to, any of these skills:
  • Low-level debugging
  • Analyzing responses to network requests
• Anyone wanting to explore the topic and can pay attention to details when reading
• Virtual machines (VMs), if you prefer not to install a certificate to allow one of your other devices to intercept your network logs. Chances are, your VM software can still store logs!
  • Note: While BlueStacks is able to replicate a Samsung environment, some security-related features may not work on Android emulation software, and the offline installer for Windows did not have the ability to disable the ads the last time I checked. The main installer works as most people expect. The offline version may be able to do that now, since I provided feedback the last time I uninstalled it.

Why?

First, switching the region on the Samsung website before logging into child accounts on a region-locked family group is fundamentally different from logging in on a device. When I created the child accounts, I was unable to log into them using another phone model from the same U.S. state as the one I created them on.

Second, Samsung Support placed me in a circular loop. The general customer support team told me to contact developer support, which referred me back to standard customer care.

And finally, I don't believe this kind of (non-commercial) advertisement would be allowed on the official Samsung Developer Forums, so I'm posting it here.

Have your Country Specific Codes (CSCs) ready

Yes, your Samsung phone (or tablet) has multiple regions, ranging from the one associated with the mobile carrier on your SIM card or eSIM to the factory one associated with where it was originally purchased from. Know the difference!

While I'm open to people using LLMs to assist themselves with understanding what they're reading, I'll also remind you of rule 4 of our community and I encourage you to exercise caution relying on them for changing the codes if you don't know what you're doing. Depending on the way Samsung customized the hardware for the specific region you intend to test, this can brick your device when a compatibility issue arises.

Useful resources:

• 600+ Samsung CSC Codes – Complete List (2026)
• Check the CSC of a Samsung phone
• Difference between CSC and Home CSC
• Change CSC on Samsung devices
• Receive OTA (over-the-air) updates after CSC change

Also, please make sure your One UI version is 5.1 or later.

About my setup

• I have AnyDesk and RustDesk.
• The Samsung account login screen has a system-level secure flag that blocks the screen from being shared, so please use the chat there for us to communicate faster during our session.
  • You can save time by copying and pasting information.
  • If you believe you may forget your offline PIN, set it to 1234.
• To prevent misuse of account credentials, all accounts require both the password and a code from my authenticator app to log in.

If you're interested, please send me a message containing the types of devices and/or emulators you have, what skills you have, your CSCs, and your proficiency in English. This is so I can practice communicating with people better, as I encounter my messages getting mistranslated often. Please include any additional information I may want to know, such as if your emulator is certified by Play Protect, so I don't assume otherwise.
