How well do you know your cell phone like? Are you really familiar with all of the functions? We'll show you five useful and amazing features that your smartphone can do, but that you probably didn't know about.
Taking photos, surfing the Internet, playing games, listening to music, or making phone calls: today it is hard to imagine life without the smartphone. It also combines many technical devices that have made it obsolete at the same time. This includes the radio, the camera, but also the handheld console and the MP3 player. However, the smartphone can also do things that many users did not know about. We'll show you five of these secret functions.
HOW LOUD IS IT
Did you know that you can measure the volume with your smartphone? Free apps like "Sound Meter" - for Android devices - or "Dezibel X" for the iPhone can measure the sound and show you how loud your surroundings are. The applications use the microphones of your smartphone for measurement and provide you with a value in decibels. For classification purposes, the apps usually show something like “Whispering”, “Quiet office”, “Conversation” or “Busy traffic”. The values are relatively accurate. However, you shouldn't use them for professional applications and instead rely on sound level meters.
HOW BRIGHT IS IT
Your smartphone has another sensor that allows you to measure the light. In detail, it is about the illuminance, which is specified in lux. With the help of apps such as “ Lux Light Meter ”, you can measure the illuminance at your workplace, for example measure and find out if it is bright enough. In-office workplaces with activities on the screen, the lighting must be at least 500 lux. This is especially important for your health, your well-being, and your performance. The values that such apps provide are only approximate and, as with sound measurement, do not replace a professional device. However, as time has shown, the smartphone has repeatedly replaced other devices. In the short or long term, these results are likely to get even better.
THE SMARTPHONE AS A LIGHT METER
Apps like " Light Meter " can also help photographers to find the right exposure time. Especially in this application, the white balance of the light can also be defined in Kelvin. This worked surprisingly well in our test.
WHAT HEIGHT AM I AT?
Have you ever wondered how high you are? Mountaineers usually have special measuring devices called altimeters or altimeters for this purpose. The altitude is usually recorded barometrically and depends on the air pressure. Some smartphones have a barometer on board. This includes most outdoor cell phones. If your cell phone does not have a barometer, you can still calculate your altitude above sea level. Apps like “ Exact Altimeter ” determine the altitude using coordinates. Such an indication is sufficient for a rough overview.
HOW TO IMPROVE YOUR SMARTPHONE RECEPTION
Are you on the move and find yourself in a street or an area where your reception is poor? Then you can install an app like “ Opensignal ” or “ Network Cell Info ”. They show you where the network coverage is better and also where the nearest mast from your provider is. This also makes sense when choosing the network provider, for example, if you are planning to move to another location.
