Partly because people replace phones more often than computers, (to upgrade, or because the screen breaks, etc) so they stop using the device before the RAM fails. But also the RAM they use in portable devices was made specifically for the device and integrated directly into the mainboard. There's less points of failure and compatibility is never an issue. Since desktop RAM can be replaced and upgraded, it's not as big of a deal if it fails, you can just swap it out with a new stick. Whereas it would brick the whole device if mobile ram fails, so quality standards are much higher.
Not to mention the differences between a soldered interface with the chip directly on the main board designed to basically be permanent, versus a simple contact interface and daughter board designed to be removable, thus adding additional points of failure.
thats correct if you consider how often you can "fix" ram by simply cleaning it.
Which I had to do to fix a mystery hard-reboot-without-warning issue I had just a couple of months ago. Connectors, especially dinky edge connectors on sensitive high-frequency components, are the weak point of most PC hardware.

Is that really so or just an assumption?
