Companies that sell cases for LG G4 phones include Otter Box, LG and Spigen. LG G4 cases are also available for purchase on Amazon.com as of 2015.
On its website, Otter Box offers three case models for LG G4 phones, as well as two shell options for changing the appearance of an existing case. These cases come in a number of different colors and range in price from $40 to $50. Otter Box cases offer protection from impact as well as dust and scratches.
LG currently offers only one type of case for the G4 phone. The genuine leather back cover comes in a number of colors and retails for a suggested price of $70. This case should provide a moderate amount of impact protection but does not have a screen protector component. It is not sealed to keep out dust particles.
Spigen offers five case models for the LG G4 as well as separate crystal screen protectors. These range in price from $15 to $35, or $10 for a set of three screen protectors. The cases available on Spigen.com offer protection from impacts, scratches and dust when used in conjunction with the screen protectors. Some cases such as the Rugged Armor model also come with kickstands to prop up the phone for touch screen use.
