Since I am likely going to get a new phone soon here, which case works the best for smart phones? I always just got the plastic shell ones but they don't seem to offer protection like I once though. I have a lot of scuffs on the edges of my current phone when I take the cover off.
Anything labeled as shock-proof will work just fine. Even if the case breaks, it should leave your phone without a scratch. Just make sure it is slightly raised and all 4 corners are covered.
If you are like me and just chuck it in your bag, then something that covers the screen for sure. I use one of those wallet style covers myself. I got mine on Amazon for like $15 and the thing protects it on ever side and every angle.
The kind that protect your phone LOL
Don't get any based on looks. Make sure there is protection on the back and the corners. Avoid anything that has too thick of a material as it can cause your phone to overheat.
