I'm not sure that the problem is fragmentation inside an operating system. It's how widespread some brands are. I never had such problems with any Samsung phone I owned, even a Sony Xperia one years ago. I guess that it means that Apple, Samsung and even Sony (back at the time) are more mainstream than Google and for shops it's not worth to keep spare parts of Google phones. To be fair, the last time I had to replace a screen of a Samsung because it dropped down flat on the screen instead of on a corner, I had to wait one day for the replacement part to arrive to the shop. I put the SIM in the old phone or in my tablet and went back the next day. I'm not replacing the screen myself, it looks to require some extra skills compared to a battery.
