Oppo is set to introduce the Reno6 series tomorrow in China, including the Reno6, Reno6 Pro, and Reno6 Pro+. There might be a Reno6 Z 5G (CPH2237) as well, which recently got certified by Malaysia's SIRIM and has now bagged certification by Thailand's NBTC.
The listing on the Thai certifying authority's website doesn't include any specs of the Reno6 Z 5G, but since its predecessor (Reno5 Z) was a rebranded F19 Pro+ 5G with slower charging and NFC chip onboard, the Reno6 Z 5G could also be based on an existing Oppo smartphone. We'll find that out at tomorrow's event if Oppo unveils the Reno6 Z 5G alongside the vanilla, Pro, and Pro+ models.
