So, it's either deal with the QC flaws on a $400 device, or annoy CS because of lack of QC. Maybe annoying them will actually make Google/Samsung do some better QC
As for the Apple part, I do agree it is kind of unnecessary. But then again if that's the tablet that works for him, then meh.
Idk, on one hand, if he really wanted the device, 5 tries at it doesn't seem too bad. On the other hand, if decent QC was actually existent, then so many replacements wouldn't have to be issued to find an "acceptable" device (for $400 I wouldn't deal with excessive screen bleed nor a creaky back either; luckily I have neither on my first device though).
