Hello. I have the Galaxy S5. Not happy at all owning it. It is overheating a lot and slips from my hands. I'm having difficulty to hold it. I tried everything I could to solve overheating, asked many people, in here too but it is hopeless. I was thinking whether to buy a brand new battery or a case that provides good grip. I decided to go to case route because it is a much cheaper way to try and see. Could you give your suggestions for cases that have good grip? If you can tell me which materials provide best grip (like silicon, TPU or plastic), I'll find the specific case by myself. I know this is some cover-up my real problem but I want to give it a shot. Thanks in advance.
