Some beliefs about smartphones or mobile devices have spread among people to the point that they are taken for granted, but these statements may be wrong or sometimes contain only half the truth.
1- It is better not to install updates as it slows down the smartphone:
The German expert, Stefan Herget, of the German technology magazine “c’t”, explained that this statement was incorrect.
Smartphone owners are always advised to install new updates regularly as the importance of new updates is not only limited to new features but also fills many security holes and fixes many bugs and issues.
Even if the devices are old and some new features delay their work in rare cases, this is not an excuse to give up installing updates, and new updates can not be omitted for reasons of security and data protection.
2- Any smartphone can withstand rain, even models without IP protection:
German expert Stefan Herget pointed out that depending on the amount of moisture and rain, a few drops of rain, for example, can not harm smartphones.
However, when the mobile device is dropped into water, it is severely damaged as a result, despite its IP protection class that protects the smartphone from foreign objects, which can malfunction or damage the electronics.
As well as water droplets can easily penetrate the mobile devices through the ports designated for the headphones and charging cable.
3- The higher the resolution of the smartphone camera, the better the quality of the photos:
This is no longer true with modern smartphones, because the quality of images not only depends on the resolution of the camera, but is related to the quality of lenses, sensors and many other technical components.
The German expert emphasized that camera software has become more important for image quality, especially during night photography or taking photos under poor lighting conditions.
4- The user must always fully discharge the battery before reconnecting it to the charging cable:
This saying is no longer true with modern smartphones, as it dates back to the days when nickel-cadmium batteries were relied upon.
The German expert rather recommended that modern lithium-ion batteries should not be completely discharged, emphasizing that the battery charge condition should not be less than 20%, as the complete discharge of the battery will damage it.
5- The cellular network must be deactivated on flights. It is also better to activate the flight mode in the smartphone, otherwise the plane will fall:
This argument is wrong, although passengers are forced to turn off their cell phones or activate flight mode during flights, but this is not because cell phones will drop the plane, but rather because it can interfere or interfere with wireless navigation systems, and therefore safety and tighten security measures in the world of aviation.
6- Using a cell phone outside during thunderstorms attracts lightning:
The German expert Hergit confirmed that this saying is not correct, because there is not enough metal in cellphones to attract lightning.
7. Smartphones that do not restart regularly slow down
This saying does not apply to the world of smartphones, unlike the world of computers, smartphone owners do not have to turn off their devices because operating systems are designed for continuous operation.
8- Making telephone calls at filling stations can lead to the risk of explosion:
This is not true, and Hergit explained that there are many signs at gas stations that warn not to make phone calls, but this indicates an increased risk of fire, which is mainly at the gas station.
The German expert advised that the smartphone should be kept in the pocket while refueling so that one is not exposed to any risks.
9- Closing open applications that are not in use saves battery charge and speeds up the workflow of the smartphone:
It depends on the age of the smartphone and the usage characteristics; Where modern smartphones automatically reduce the consumption of applications for energy, so there is no longer a need to close applications, on the contrary, the user saves energy when he leaves open the applications he uses a lot and does not have to constantly restart it not, but with old devices it may make sense to close Applications.
10- Smartphones can be infected with viruses via SMS:
Hergit stressed that this argument is not correct, as viruses can not be transmitted directly in this way, but hackers and scammers may send links to phishing websites or download malware via SMS.
