To take a broken phone to the mall where there're a small store that's known to fix phones?

Yes, precisely. That puts the onus for the fix squarely on the users, who have not created the problem and who likely will mis-identify it. If it were to happen to me - it won't - it would cost me half a day and that's assuming the 'small store in the mall' will be able to do the repair on the spot, which if there is a glut of customers due to this issue may well not be the case.
