Hi! Thanks for the very interesting question.

These are the reliably documented effects of cell phones on electronic
devices which I found during my research.

Mobile phones affect other electronic devices indeed and at times at
the risks of our lives. Most of the effects are caused by the radio
signals generated by the cellular phones.

One of the most documented effects it has are on the subject of ears
as well or hearing aids.

“People with a hearing device may experience an interfering noise when
using a mobile phone or when one is used nearby.”

“The interference is caused by the radio signals generated by the
mobile phone. It can be a buzzing sound that makes speech hard to
understand. In severe cases, it can make the phone unusable.”

“Hearing aids and mobile phones” 

“Cell phone-related interference was detected in electrocardiographic
(ECG) tracings displayed on monitors when phones were placed at a
distance of 6 to 33 inches from the medical devices. Phones held
beyond a radius of five feet would not affect ECG displays,
researchers hypothesized.”

Mechanical Ventilator:
“The most severe interference related to cell phone use was detected
when a phone was held near a mechanical ventilator. The ventilator
shut down and restarted when the phone was held within two inches of a
communication port on the back of the ventilator. “

Medical Equipment Monitors:
“Other findings indicate that digital phones produce noise and some
movement on baseline readings, while analog phones cause movement on
monitor readings. Mobile phones used at a distance of 60 inches from
electrical equipment within a patient's room or a central nursing
station are unlikely to cause serious equipment malfunctions, the
researchers said. “

“Study: Cell Phones Interfere with Medical Devices” 

“Questions and Answers About Wireless Phones” 

The following other devices are affected cellular phones according to
this manual: The page on the manual in which this was taken was on
page 13 to 14. The document is in PDF file so you will need the Adobe
Acrobat Reader to read it. In case you haven’t installed it yet here
is a link so you could download The Adobe Acrobat Reader

Pacemakers: (Yet another medical device)
“The Health Industry Manufacturers Association recommends that a
minimum separation of six (6") inches must be maintained between your
device and a pacemaker to avoid potential interference with the
pacemaker. These recommendations are consistent with the independent
research and recommendations of Wireless Technology Research.”

Electronic Devices in Cars:
“RF signals may affect improperly installed or inadequately shielded
electronic systems in motor
vehicles. Check with the manufacturer or its representative regarding
your vehicle. You should also consult the manufacturer of any
equipment that has been added to your vehicle.”

“FCC regulations prohibit using your device while in the air. Turn
your device OFF before boarding an aircraft.”

Potentially Explosive devices or machines:
“Areas with a potentially explosive atmosphere are often, but not
always marked clearly. Potential areas may include: fueling areas
(such as gasoline stations); below deck on boats; fuel or chemical
transfer or storage facilities; vehicles using liquefied petroleum gas
(such as propane or butane); areas where the air contains chemicals or
particles (such as grain, dust, or
metal powders); and any other area where you would normally be advised
to turn off your vehicle engine.”

Vehicles with Air Bags:
“An air bag inflates with great force. DO NOT place objects, including
either installed or portable
wireless equipment, in the area over the air bag or in the air bag
deployment area. If in-vehicle
wireless equipment is improperly installed and the air bag inflates,
serious injury could result.”

Mobile phones obviously affect our computer monitors but actually it
could damage computer systems as a whole.

“Many operators in industry have banned the use of radio equipment in
computer rooms, near input and output interface panels, within control
centres or near to shutdown systems.”
