Hmm, I don’t remember anybody doing a dual camera setup for telephoto and bokeh effect prior to Apple. The only one I remembered was HtC putting dual camera for 3D effects.When the next iPhone comes out you will see Apple implementing their own version of what we saw on the P20 Pro and P30 Pro
In this tech industry there are always people either knocking of others or modifying what others did. Apple only had single lense cameras but when others added 2 they added 2 and now others added 3 and they are adding 3. When Apple came out with iPhones they had a single SIM card option only for the iPhone but when Chinese offered dual sim and it sold well they started doing the same as well. In the tech industry this is normal.
And we have had dual SIM way before the original iPhone. Plenty of old feature phones with dual SIM. It’s not a recent Chinese thing. Stop making it like the Chinese came up with these stuff. Apple didn’t do dual SIM early on because dual SIM is practically unknown in the US. Even Samsung phones are only single SIM in the US, while the same model is dual SIm outside. Since iPhones are primarily designed with US centric in mind, it’s not strange to not come in dual SIM right away. Even the OnePlus One for the US was only single SIM, and that’s a Chinese phone.
