Oppo just announced a few worlds first. 

First OPPO has made a huge breakthrough in smartphone photography. They have developed the first-ever sensor-based image stabilizer for smartphones. It’s also the smallest image stabilizer, for any type of device, in the world. It stabilises quicker and over a great movement and uses 50 times less power to operate. This also reduces heat. 

  
Next Oppo announced a new safer fast charging system that charges a phone fully in 15 mins. This is done at a safer 5 volts too. This is for a battery 2,500mAh battery. 

All in all a good day for innovation for Oppo.
