I don't have original box or receipt, but ever since I bought the alcatel pop astro it has repeatedly rebooted for no reason in the middle of calls and such, its been dropped a slight crack, but my main concern is it actually working. It rebooted before the drop. I also just bought this phone in the past three weeks and a alcatel one touch evolve 2 with the same problems bought in the past week.
Usually you need the receipt for the warranty. But getting your screen cracked, I don't think you'll be able to get a replacement for your phone anymore.
