These are just examples, I have no opinion on what is the best.
Something like: I like the cameras from the Galaxy s23, the processor from the latest Pixel, the memory from the Razor. I mean whatever. I suppose Iphones could be included, but I figure it’s more locked in than androids, I could be wrong.
Or even replacing a part from one phone with one that’s better, for personal use? Like, even just putting pixel 7 cameras into a pixel 8 phone.
Besides the factory warrenty, and money spent, is it software? Is it having to reconfigure the hardware? Is it just space in general?
If we all have things we don’t like about our phones, why aren’t we able to just make it more to our liking?
Essentially time and cost? Building such a Frankenstein-Phone would probably take you half a year to design the PCBs, get all the connections and power rails right, all the needed peripheral electronics for the chips. Read thousands of pages of datasheets to place the correct capacitors for the oscillator of the … sensor on your mainboard design. (And there are a lot of tiny components in a phone that all work together, in part depend on each other, or require additional control/supply circuits.) You’d need a lab and equipment do build it, and the mechanics and encasing. And probably some takes and failed iterations. And software and drivers also have to be rewritten and patched.
So I’d say if you have the expertise in electrical engineering, hardware design, embedded software programming… A 5 figure(?) sum of money for supplies and equipment and nothing to do in the next year… I’d say nothing is stopping you 😆
Well that seems like more effort than it’s worth… I figured the biggest issue would be fitting it into the phone, but that sounds like least of the worries.
