OPPO officially held a ceremony in China where it officially unveiled the OPPO R15 premium midranger. The smartphone will go on sale on April 1 in China. The OPPO R15 comes pre-instaled with Color OS5.0 which is based on Android Oreo.
Now, older OPPO models like the R11s and R11s Plus will soon have the opportunity of running Android Oreo-based Color OS 5.0. Presently, OPPO has officially started pushing Color OS 5.0 public beta update to OPPO R11s and R11s Plus users. Adaptability of the new custom ROM on the R11s shouldn’t be difficult as both models equally come with a full-screen design except for the notch design which highlights the R15’s display.

The OPPO R11s and R11s Plus were launched late last year with a full-screen design. The models run on Android Nougat -based ColorOS 3.2 at launch. The new ColorOS 5.0 operating system adds a new system theme, and the desktop content is completely new. The control center is merged with the notification center. The bottom of the screen slides out and the shortcut switch operation is easier to use. The Android security patch was also updated to February 5, 2018 to enhance system security.
