In the mobile phone industry, nearly all parts have a very short life span. So short in fact that if you start designing a product with available parts, you might end up releasing it just as they reach end of life.No they don't, it's in "legacy mode" already.
A miracle, that such a short-support-strategy doesn't lead into bankruptcy, who buys chips that are not supportet anymore after 1-2 years? Why it just can't be like onto PC where I get still new drivers for my 5 year old graphics card? is it really that hard onto the SoC front? Especialy when I see what new drivers can still pull out of older hardware sometimes.
