Why your cellphones may explode?

We all must have heard of an incident of cellphone explosion at least once in our lifetime. Phones are treated like a plaything these days.But, have you ever wondered that why such serious cases occur?What are the dangers if these phones are not handled with care? What effect does it have on our health?

First, take a look at why and how do mobile phones blast?

The biggest mistake that people do is using their phone while it is being charged, which is sometimes called 'Call Bombing'.This is because, charging puts pressure on the motherboard of the phone.So using it during charging increases this pressure manifold. Again a threat to the cheap electronic components to explode.

Sometimes, there is also a malware, or bug, found in some Android-based smartphones, that can also cause explosion by exerting extra pressure on the motherboard during charging.

Prevention:

• Make sure that the phone is not over-charged by removing the electric supply when the battery is fully charged. If your battery seems to have swollen, replace it immediately.

• If you wish to receive or make a call, disconnect the phone from the charger and then proceed.

Second, avoid buying cheap models like those of Chinese make, which use components that are not branded and are of compromised quality.These cheap components if continued to be used for a long time may result into disastrous consequences!
Care must be taken while buying a phone. Buy a branded phone as far as possible and check that the phone has a proper IMEI (International Mobile Equipment Identity), which uniquely identifies each phone.Check that the number on the phone corresponds to that on the box and receipts.

Third, it is harmful to surf internet or download anything on mobile phones.

• One should avoid downloading anything from a third party vendor, ie directly from the internet browser. Instead use the in-built store or market application provided by the operating system, because the anti-virus softwares for mobile phones are not as effective.

• Also make sure that sites you visit using the phone must start with an https (which means they are encrypted or safe sites).

• Avoid using public or unsecured Wi-Fi connections and make sure the Bluetooth connectivity is not switched on in public places as it can be used to send malicious files which may corrupt the operating system.

Dealing with a wet phone:

If you come across a situation in which you have to deal with a wet phone.Simply dismantle it by removing battery, SIM and memory cards.Dry each component gently with a towel until it is dry to touch.In order to remove the remaining moisture, put all the components in a bowl of uncooked rice in a way that all the components are fully covered.Leave it for 12-24 hours.
!Never try to dry the components of the phone with a hair dryer.Drying it with a heated hair dryer may cause important parts to melt, while forcing water further into the phone.And drying it with a cold hair dryer will just force water deeper into the phone.

Precautions that should be taken with phones: 

• All are well aware of the harmful electromagnetic radiations that mobile phones emit.So try to keep your cell phone away from the body as this may reduce the effect of the rays.

• Whenever possible, use the speaker-phone mode or a wireless blue tooth headset.

• Do not carry your phone with you all the time near to the body.When in pocket, make sure that the keypad is positioned towards the body so that the radiations move away from the body.

• At night, put it on 'flight' or 'offline' mode, which stops electromagnetic emissions.Avoid keeping the phone under the pillow or beside the table, while sleeping.
