Why do mobile phones blast? Do phones blast during charging or when using any connectivity tools like tethering etc? Is the main problem behind these phone blasts are heating issue or any current shorting within the battery?

From what I see if you are using a fake charger, it could blast and could cause fire, I don't think a phone will blast while charging if the charger is in good quality.
Yes, especially in a low circuit  and using not standard charger and while using the phone when charging.

Here are seven reasons that could be the cause of your mobile phone exploding.

1. Not using the original charger.

2. Using a low quality car charger.

3. Charging the mobile from other device types.

4. Charging the battery that is already full.

5. Having a battery that has been damaged or defective.

6. Using the mobile while charging.

7. Charging the mobile near a hot source.

In most cases mobilephone blasts are happening due to continuous over heating of the device. There are many possibilities to this overheating.
1) Exposing to sunlight or any heat source for a prolonged time.
2) Faulty or duplicate battery getting shorted.
3) Shorting of cutoff coil. There is a coil that acts as a relay when the phone is in idle or switched off. The damage to this coil may result in serious heating issues which may cause an explosion.
4) Keeping a phone in wifi tethering to use mobile data along with other devices while the device is plugged-in to the charger for a long time. This simultaneous charging and tethering will lead to overheating and thereby damaging other components too.
Mobilephones are not designed to use as a WiFi router or tethering machine. These features are there to use only for a short time.
5) Water damage is the another big problem for overheating of mobile phones. Waterlogged phones will get damaged by shorting of various components including battery and it may result in an explosion.

The best way to reduce this risk is to get proper service to your device if it gets a sign of overheating.

I heard this news from a  newspaper. The reason may be due to overheating. Better avoid using mobile phones while charging. Keep phone unplugged from the power source and the power cable from phone whenever you get an incoming call.

Yes it can especially when you're using your phone while its charging because there's imbalancement of charge.Its advisable to let your phone charge to 100% then use it.

Also,your phone might blast if the current supplied to the socket it's too much and that's why its advisable to use extensions to connect them to the wall sockets.

Finally your phone can easily blast if you expose it to direct heat maybe heat from stove or a 'jiko'.This way, the battery will be exposed to so much heat than it can stand making it explode.

Yes, there are multiple cases where overcharging leads to blast because of overheating but now smartphone companies have inbuilt the system in mobiles that if you keep your mobile on charge it will automatically stop after getting fully charged. But more or less you need to take this responsibility to switch off the charging plug to keep you and your mobile safe.

Well there are a lot of cases where phones have exploded due to overcharging or using low quality chargers and batteries (for the removable ones). Also, this case is not confined with phones. It does happen to laptops that are left charging for a long time.

Surely, the mobile phone will explode if there is a defect or it was being overcharged. There are some stories circulating on the Internet that people died while phones are at their sides while charging, which is not advisable for us to do.

Yes, It can be blost while charging.

Charging puts pressure on the motherboard of the phone using it during charging increase this pressure manifold. This causes the cheap electronic components in some mobile to explode.
