OnePlus' latest India-exclusive phone, the OnePlus 9R, is getting its first system update. The slightly boosted OnePlus 8T is in for some small improvements across the system and some apps as part of OxygenOS 11.2.1.1.

The update is starting to roll out to phones right now. The most significant improvements revolve around charging, which is now supposed to be more stable. There are also fixes for volume level issues when using two SIM cards and a delay for incoming calls during charging. The changelog also specifically calls out Call of Duty Mobile, which now offers improved haptic feedback on the phone. Then there are improvements to the gallery, the clock, and the Wi-Fi hotspot performance.
