Query: When was the first cellphone developed?
Prior to 1973, mobile telephony was limited to phones installed in cars and other vehicles.[19] Motorola was the first company to produce a handheld mobile phone. On April 3, 1973, Martin Cooper, a Motorola researcher and executive, made the first mobile telephone call from handheld subscriber equipment, placing a call to Dr. Joel S. Engel of Bell Labs, his rival.[25][26][27] The prototype handheld phone used by Dr. Cooper weighed 1.1 kilograms (2.4lb) and measured 23 by 13 by 4.5 centimetres (9.1 by 5.1 by 1.8in). The prototype offered a talk time of just 30 minutes and took 10 hours to re-charge.[28]
The LG Optimus Zip (also known as the LG Enlighten for Verizon and the LG Eclypse in Canada) is an Android-powered cellphone developed by LG Electronics, Inc.. It was first released on September 22, 2011 on Verizon Wireless in the United States.
Some indications of possible cellphone surveillance occurring may include a mobile phone waking up unexpectedly, using a lot of the CPU when on idle or when not in use, hearing clicking or beeping sounds when conversations are occurring and the circuit board of the phone being warm despite the phone not being used.

"Cellphone's Dead" was first performed on stage in early 2005, when its title instead was "Knock Out." The main rap verses were still in the song, although the chorus was different.
Madeline Pynch is a rich woman who is the mother of Priscilla Pynch, works at an as-yet-unnamed company, and is good friends with Mayor Luskey. In "Spellbound", she planted golden cellphones around town which mesmerized people to help in her company's plot to get to the gold that is underneath Blossom Vale, in which they were passed down to everyone (including the Rescue Bots) but Cody. Her plan to mine the vale went into operation and managed to reap some reward before the cellphone controlling Boulder falls off and he helps Cody take down the cell tower, breaking the hypnotic hold over the town's residents. When Priscilla later told her mother that she found a cellphone under the seat of the limo that they are in, her mother said it was a model that was being recalled while reflecting that the cellphones put out would have to be much stronger.
The NSA has cracked the most commonly used cellphone encryption technology, A5/1. According to a classified document leaked by Snowden, the agency can "process encrypted A5/1" even when it has not acquired an encryption key. In addition, the NSA uses various types of cellphone infrastructure, such as the links between carrier networks, to determine the location of a cellphone user tracked by Visitor Location Registers.
Cellphones can easily be obtained, but are also easily traced and "tapped". There is no (or only limited) encryption, the phones are traceable – often even when switched off – since the phone and SIM card broadcast their International Mobile Subscriber Identity (IMSI). It is possible for a cellphone company to turn on some cellphones when the user is unaware and use the microphone to listen in on you, and according to James Atkinson, a counter-surveillance specialist cited in the same source, "Security-conscious corporate executives routinely remove the batteries from their cell phones" since many phones' software can be used "as-is", or modified, to enable transmission without user awareness  and the user can be located within a small distance using signal triangulation and now using built in GPS features for newer models. Transceivers may also be defeated by jamming or Faraday cage.

Preventative measures against cellphone surveillance include not losing or allowing strangers to use a mobile phone and the utilization of an access password. Turning off and then also removing the battery from a phone when not in use is another technique. Jamming or a Faraday cage may also work, the latter obviating removal of the battery.
Another solution is cellphone with physical (electric) switch, or isolated electronic switch that disconnects microphone, camera without bypass, meaning switch can be operated by user only - no software can connect it back.

The secondary circuit is floating, when you touch the secondary circuit, you merely drag its potential to your body potential or the earth potential. There will be no current flowing through your body. That's why you can use your cellphone safely when it is being charged, even if your cellphone has a metal shell and it is connected to the secondary circuit.
