There is no stereo speakers in realme 6 pro...

Dont think 60Hz to 120Hz display refresh rate are technology breakthrough 
I havent own smartphone with over 60Hz display refresh rate yet, so cant be 100% sure, but I think the 'smoothness of user experience' largely affected by OS/software optimization.
When I use OG Pixel XL few years back, I'm amazed at that iOS level smoothness, but when 'upgraded' to newer phone like poco F1 and xiaomi mi9T, that extreme smoothness gone missing. Poco F1 does felt fast but not smooth.

IMO what's require are higher than 60hz, let's say 90Hz. So when framerate dropped ( which happened on games required heavy resources ), it dropped from 90fps to 72fps etc, which still felt smooth.

I think it's just cost, LCD are easier to get high refresh rate. See laptop with LCD and AMOLED option.
but possibly like other speculated, they cant over-come big brother xiaomi 

It doesn't say the warranty by who.

Too close to Mi 10 and OP8 prices already if that is the case.

Cheapest K30 Pro I found is about RM1,999. Doesn't make sense for the Poco F2 Pro to cost fee hundreds more than that since it's essentially the same phone.

Just got my k30 pro zoom this evening... Something is definitely off with this phone's battery performance.

Its kinda insane by my usage standard. All my previous phones had around 3000mah battery (biggest was Note8), but all of them can barely survive 3.5 hours SOT. But this phone is currently reaching 4hrs mark and still have 65 percent of battery charge. Sure the battery size is definitely bigger, but I didn't expect it to be this good.
