How to Dry a Cell Phone After Water Damage?
There is nothing worse than dropping a cell phone in water. Instant panic may arise, but if the cell phone owner acts quickly, damage to the water damage to the cell phone may be minimal. There are six steps to drying a cell phone after water damage.Step 1 - Remove the cell phone from water immediately. There is no time to waste. The longer a cell phone stays in water, the more water damage is likely to occur. Even if the cell phone has fallen in the toilet, it must be immediately removed.Step 2 - Take out the battery and SIM card. Removing the battery will prevent short circuits from damaging internal components required to operate the cell phone. The battery should be removed and immediately placed on a paper towel. If the cell phone has a SIM card, remove that as well.Step 3 - Wipe down outside and inside the battery compartment. With a paper towel, wipe down the inside and outside of the cell phone. Use slow strokes to prevent lint from jamming into keys or small holes in the phone.Step 4 - Place the cell phone and battery in a bowl of rice. Rice absorbs water quickly. Immerse the cell phone in a bowl of rice and allow to sit for 24 hours. While rice works well, those small packets found in shoe boxes or other packaging to absorb water work even better. Before searching for a moisture absorption packet, immerse the cell phone and battery in the rice. If a packet is found, place it inside a plastic bag with the cell phone and battery, seal and allow to sit for 24 to 48 hours.Step 5 - Remove residue from the cell phone. Rice can leave fine residue on the phone. With a vacuum cleaner, suck away residue. Do not hold the vacuum cleaner too close to the cell phone as static can cause damage to internal circuits.Step 6 - Reassemble and test the cell phone. Replace the battery and battery cover. Turn the cell phone on to see if water damage has been prevented. If the battery is dead, plug into an electrical socket and then try to turn on the power. If nothing happens, significant water damage may have occurred and a professional should disassemble the phone completely for maintenance and repair.Water damage can be determined by viewing the small white square located on the cell phone battery or inside the cell phone compartment.

What is the history of the cell phone?
Everything started out on October 18, 1842 when Samuel Morse passed telegraph signals through water. This led to the idea of wireless by conduction. Then, in 1865, a Dr. Mahlon Loomis was the first person to communicate throught wireless atmosphere. In the 1970's Motorola and AT&T were competing to see who could be the first to invent a mobile phone. Motorola won! On April 3, 1973, Martin Copper from Motorola made the first ever cell phone call in New York City to his competitors! The first cell phone invented was Motorola s Dyna-Tac in 1973. It was 9*5*1.75 inches. It weighed 2.5 pounds and had no display. It used 30 circuit boards and the talk time was only 35 minutes. Then you had to charge it for 10 hours! In 1978, AT&T and Bell Labs held public trials with 2000 trial customers for cell phones in Chicago. The first commercial cell phone system was in Tokyo in 1979. Motorola and American Radio had the 2nd US cellular radio-telephone test in Washington/Baltimore. Then, in 1983, Motorola produces the 16 ounce Dyna-Tac. They sold for $3500 each! Well, that's a little of the history of the cell phone.

How was cell phone made?
After the technology necessary to establish a two-way phone connection was developed in the late 40s and 1950s, the two American companies AT&T and Bell Labs engaged in competition to make the first commercially viable cell phone, something that eventually led to the development of the hexagonal-based grids that allow cell phones to function. The credit for developing the first successful cell phone, however, goes to Martin Cooper, who made the first successful test of his model in 1973 when working for Motorola, which was in competition with Bell Labs.
When was the first cellular telephone tested?
It was made in 1947 by Bell Labs, but it really didn't get into use until Dr. Martin Cooper of Motorola produced a usable cell in 1974. This phone was only for government use and in 1984 it was sold to the general public.
