Samsung is currently the only vendor making 100+ megapixels sensors and rumor has it that the company will pull even further ahead of the competition with a 150MP sensor later this year.
This sensor will be massive - 1", comparable with the Sony RX100 cameras. That is noticeably larger than the 1/1.33" ISOCELL Bright HMX that was the first 108MP sensor. Better yet, it will finally top the 1/1.2" sensor that the Nokia 808 PureView used.
Samsung's 150MP sensor will use the nonacell pixel binning tech (9-in-1), resulting in 16MP shots, up from 12MP shots that the Galaxy S20 Ultra produces (the version of the sensor used by Xiaomi only supports 4-in-1 binning).
Xiaomi is expected to be the first to use the new sensor in a phone, set to launch in Q4 of this year. Oppo and vivo will follow in early 2021. Naturally, Samsung will use the sensor in its own flagships too, likely starting with the next Galaxy S phone, given the time frame.

Now we are at a point where the quality of the optics are more important than ever... Manufactures will have to bend light in impossibly precise ways to get a clean image onto the sensor...
No they don't. They tend to be smaller sensors, with smaller pixels, dimmer apertures, and even not be as good in focus tech or ois. So no. They definitely don't capture the same amount of light.
