Samsung phones are made in Vietnam?! Talking about those I just fixed my Play installation by "uninstalling" in settings, which really reinstalls the original one and re-updates. This is the second time my Android phone nukes itself (by popping up "App is crashing, closing it" over and over again) without any interaction from me, because of some hidden update; last time it was Chrome, and the fix is always to reinstall the offending app which not a single help page in the whole internet describes!
