LG G4 User Manual page 167

Do not use harsh chemicals (such as alcohol, benzene, thinners, etc.) or
detergents to clean your phone as this could cause a fire.
Do not place or answer calls while charging the phone as it may short-
circuit the phone and/or cause electric shock or fire.
Explosion, Shock, and Fire Hazards
Do not put your phone in a place subject to excessive dust and keep the
minimum required distance between the power cord and heat sources.
Unplug the power cord prior to cleaning your phone, and clean the power
plug pin when it's dirty.
When using the power plug, ensure that it's firmly connected. If not, it
may cause excessive heat or fire.
If you put your phone in a pocket or bag without covering the receptacle
of the phone (power plug pin), metallic articles (such as a coin, paperclip
or pen) may short-circuit the phone and may cause an explosion. Always
cover the receptacle when not in use.
General Notice
Do not place items containing magnetic components such as a credit
card, phone card, bank book, or subway ticket near your phone. The
magnetism of the phone may damage the data stored in the magnetic
strip.
Talking on your phone for a long period of time may reduce call quality
due to heat generated during use.
When the phone is not used for a long period time, store it in a safe place
with the power cord unplugged.
Using the phone in proximity to receiving equipment (i.e., TV or radio)
may cause interference to the phone.
Do not use the phone if the antenna is damaged. If a damaged antenna
contacts skin, it may cause a slight burn. Please contact an LG Authorized
Service Center to replace the damaged antenna.
