Root issues connecting via Bluetooth

OnlyBusyBee — Sun, 21 Sep 2025 11:43:54 GMT

Hi,

I have had my POS for a couple years now. Gen 2. It used to work fine on my current phone, but I am just getting ready for the summer season and it will not connect from my POCO f4 to my hardware. I keep getting a message saying it won't connect to a rooted phone. It is not rooted and I have also done a factory reset just in case. Please advise what I can do. Do I need a new Square POS? Or does my phone no longer work with it? Any advice greatly appreciated.

Hi, @OnlyBusyBee !

This is a known issue that can occur with some Android phones, particularly certain models like POCO, Xiaomi, and other brands. Here's what's happening and what you can try:

Root Detection Issue:
- Some phones, even when not rooted, can trigger Square's security checks
- POCO phones (part of Xiaomi) sometimes get falsely flagged due to their custom Android implementation
- Factory reset alone might not resolve this as it's related to system-level security settings
Troubleshooting Steps:

a. Check Square App Settings:
- Uninstall the Square app completely
- Restart your phone
- Reinstall the latest version from the Google Play Store
- Make sure to grant all required permissions
b. Phone Settings to Check:
- Go to Settings > Security
- Ensure "Allow apps from unknown sources" is disabled
- Check if there's a "Device Security" or "System Security" option that might be affecting app verification
c. MIUI-Specific Settings (since POCO uses MIUI):
- Go to Settings > Additional Settings > Developer Options
  - If Developer Options isn't visible, go to Settings > About Phone and tap "MIUI Version" seven times
- Make sure "USB Debugging" is turned OFF
- Look for and disable any options related to "root access" or "system verification"
d. Check Square Compatibility:
- Visit Square's website to verify your phone model is supported
- Ensure your Android version is up to date
- Check if your phone's security patches are current

Let me know if this helps!

Thank you so much for taking the time to respond to me.

I have tried all of the suggestions and now cannot get the reader to pair with my phone!

However, I have decided it is high time I get a more up to date mobile, so I will await it's arrival and see if that helps.

Thank you again
