Is Oppo developing a sliding smartphone – we think it’s still only an idea null

Smartphones that fold up and flip open seem to be back in vogue. So, just when Samsung has announced its readiness to launch the Galaxy Z Fold 2, comes the news that Oppo could now be developing a sliding device with an extendable display. 

Right now, all that we know about the new device comes from  a bunch of sketches that are part of a design patent. Oppo seems to have filed the new patent with the China National Intellectual Property Administration or the CNIPA some time in the recent past.
