Both the Oppo K13x 5G and Vivo T4R run on Android 15 and share many operating system features. These include clipboard warnings, location privacy options, camera/microphone privacy options, theme customization, and the ability to block app tracking. Both devices also support dark mode, have on-device machine learning, customizable notifications, and Live Text. Additionally, both phones offer media pickers, can play games while they download, and support split-screen functionality.
While they share several features, there are no key differences between the two in terms of operating system capabilities. Neither phone supports Wi-Fi password sharing, has a Mail Privacy Protection feature, or gets direct OS updates. They both have a child lock, offline voice recognition, voice commands, and can track the device's current position. Both also support widgets, dynamic theming, and PiP (Picture in Picture) mode, as well as full-page screenshots and focus modes.
One area where they both match is in their openness—both devices are free and open source and support multi-user systems. Features like battery health check, the extra dim mode, app offloading, manual exposure, and Quick Start are available on both phones as well. Neither device can be used as a PC, and both lack laser autofocus or the ability to block cross-site tracking. Overall, the two devices have identical operating system features, making their software experiences largely the same.
