Drivers from 3rd party. Didn't work on phone development, but was part of a company that developed setup boxes.
We will get a kernel from broadcom with all the necessary drivers that was tested for that configuration. Updating was very hard without support and might cost a lot.
They had a lot of excellent scientists.
Fun fact, the math behind radar stealth was developed by a Russian scientists and was ignored in URSS because it had a shit title. US delayed translating it because they didn't undersrand the title. After a few years somebody at lockeed marting found it and realized what it meant. I think F-117 was developed based on that.
Same for me.
