The last bit is a little hard to interpret, but it seemingly suggests that the price of the Galaxy Z Flip 3 will be within KRW 1,000,000 (~$904) in South Korea. For reference, the Z Flip 5G costs KRW 1,650,000.
Alternatively, he might be suggesting that it will be priced under 10,000 Yuan (~$1,520), which sounds more plausible. The LTE model costs 11,999 Yuan in China, in case you are wondering.
Either way, it appears that the Z Flip 3 will be more affordable than the Z Flip 5G, which cost $1,450 in the US.
Although the screen will likely remain the same 6.7-inch size as the Z Flip 5G, it will be protected by an improved version of Ultra-Thin Glass. We can also look forward to a bigger battery, stereo speakers, and an upgraded hinge.
The device will likely arrive in Q2 2021, presumably in April. Samsung is reportedly planning to launch five foldable phones in 2021, so we might also see a stripped-down version of the pocketable device.
