one thing i've learned with my phones in the past is that the less you spend on a case, the better it usually is.

i just got a basic flexible/rubbery case on amazon for like 6 bucks. protects it very well. even if you drop it with the screen facing down, the case comes out a little around the border of the phone to take the force of a fall (instead of the screen).

for some reason i couldn't find it on my amazon account, but i think this one was it
