Smartphones and phone cases are considered complementary goods because the demand for phone cases increases as the demand for smartphones increases. This is because phone cases are often purchased to protect and personalize smartphones, making them a natural pairing.
The best materials for durable cell phone cases are rubberized and gel materials. Cell phone cases made of these materials are flexible and generally unbreakable. They prevent slipping and breaking of a cell phone.
There are cases that allow cell phones to be placed upright. These cases can be purchased. They can be found on Amazon or other websites.
It would be better to mention the model of your cell phone. If you are in the USA you may check "Mobansp" where you can get all types of phone cases and accessories.
Rubber cases protect the phone from scratches. But I would not venture to say that the rubber case makes the phone impurvious.
Cell phone cases can be bought at any electronic stores, or at any shopping mall, there always some small stores that carry cellphone cases. May be you would want to try Wal-Mart, BestBuy etc.
