Good day Romiyo, thank you for asking us your question about the Samsung Galaxy Watch8. Yes, the advertised Galaxy Watch8 can connect to non-Samsung Android phones running Android 11 or higher via the Galaxy Wearable app. While most features work, some, such as ECG, require a Samsung Galaxy smartphone. The Watch8, however, is not compatible with iPhones. Feel free to check out, "Samsung Galaxy smart watch and phone compatibility" if you would like to learn more about compatibility. Let us know if you have additional questions for us by contacting Support. Thank you for choosing Samsung! - Debra
