I am just pissed that my semi expensive case which I have used for other phones (the brand), has failed to protect the back. It may not be water proof anymore. But I am not recommending that brand anymore. (I have bought this brand since the LG G2.
hybrid rubber/plastic cases arent always good Honestly i find the $10 Chinese cases to outperform the $40 variations
Only if its damaged enough. You can always be gentle with it and youll be OK. Also its perfectly fine if you cover it up then use it
