OnePlus 13T 5G PKX110 Dual Sim 512GB Pink (16GB RAM) - China Version

Which OS is installed at Oneplus 13T
Etoren Customer Posted on Mon Jul 07, 2025 05:06 AM	Hello. Your ad states that Android 15, Oxygen OS 15, and Color OS 15 are available as operating systems. Which of these three operating systems is installed? Is there a way for you to pre-install an OS?
