  • Hey, I bet youre so used to a smartphone in your hand that youve never even asked

  • yourself a question: why in the world is it rectangular? Why not square or round, for

  • example? Or why, for that matter, you can’t use it when in gloves? Yeah that bugs me.

  • Well, let’s find out, shall we?!

  • Ever tried using your phone on a sunny day? Yeah, even turning the screen brightness up

  • to the max isn’t gonna work. Why can’t they do something about it? LCD screens, in

  • fact, sacrifice visibility for better color reproduction. There are screens that show

  • a clear picture even in direct sunlight, but the color quality in those is much worse.

  • They are mostly used in GPS navigators and watches because you need to see the objects

  • on them, while phone manufacturers keep in mind that you could watch movies and play

  • games on their products. Try doing that under the glaring sun, though.

  • It's not recommended to use your smartphone while it’s charging, but for some reason

  • it’s the opposite for laptops. That reason is heat generation: smartphones are small,

  • so all the heat they accumulate goes to the battery, damaging it over time. While charging,

  • your phone heats up, so using it might shorten its life. In laptops, the battery is well

  • isolated from the rest of the parts, and the heat goes around it. And keeping the charge

  • of the battery up prolongs its service time, so feel free to plug it in and work all you

  • like. Isn’t it a bit unfair that electric cars

  • can be fully charged within an hour, but a much smaller smartphone battery needs at least

  • the same time or even more? Electric cars have large batteries with separate cooling

  • systems that don’t allow them to overheat while charging. Smartphones will need equally

  • good cooling not to melt down if charged too fast. And that adds a lot of extra weight.

  • And on the topic of chargingIf you charge your smartphone in the cold,

  • you may notice it goes up slower than usual. This happens because charging involves chemical

  • reactions. They need a certain range of temperatures for optimal work, so if it’s too cold or

  • too hot, your phone will charge more slowly. Its overall performance will be reduced too,

  • so better keep it in neutral conditions. You probably know that blue light from screens

  • of smartphones and computers can mess with your sleep. In modern gadgets, though, there’s

  • an option calledeye-saver modeoreye comfort.” It cuts off part of the blue light,

  • making the screen yellowish, but letting your eyes and brain rest. It’s especially useful

  • if you work with documents, since you don’t need a full color palette. It’s best to

  • turn it off only to watch videos or play games to enjoy the juicy picture, and keep it turned

  • on the rest of the time. The expressionis the

  • new blacksuits smartphones and other gadgets like nothing else. Even when there are other

  • color options, black is almost always one of them. The reason boils down to black being

  • a universal color that fits any surroundings. You might sit in an orange-toned room, dressed

  • in green and blue, but your black smartphone or black TV will still look okay. Same goes

  • for white and greyall these three colors go well with any other.

  • Now look at an average smartphone and an equally average tablet PC. Go ahead, I’ll wait.

  • Done? okay. The latter has a bigger size and better computing power, but it’s still cheaper

  • than the smartphone we have here. That’s because the phone has a radio chip and the

  • tablet does not. Radio chip is probably the most complex part of a smartphone: it has

  • to be able to work with dozens of different frequencies across the globe and have a huge

  • range for you to easily talk to anyone in the world. Tablets, on the other hand, don’t

  • need a radio chipthey have a Wi-Fi one that works with just two standard global frequency

  • ranges and covers a few hundred feet. Hence the difference in cost.

  • In winter, it’s annoying that you have to take off your gloves first and only then answer

  • if someone’s calling you. Or you can use your nose instead. The screen reacts to conductive

  • materials, and only if theyre a little squishythey can activate several sensors

  • at once this way. Gloves don’t conduct electricity, so you either need to use your bare fingers

  • or buy yourself a pair of gloves with special fingertips. Theyre tipped with some rubber

  • and conductive powder to imitate fingers. When something’s wrong with your device

  • and you contact tech support, the first question they’d ask isDid you try turning it

  • off and back on?” Seems weird, but it actually works. Whatever process is running on your

  • gadget, it leaves a trace even when you close it. The more processes you run and then close,

  • the more such traces are left in the memory of your device. And at some point, it might

  • stop working properly. Rebooting your device helps clear all the unneeded residue and optimize

  • its work. Better yet, reboot once a week to avoid this trouble altogether.

  • Now take a good look at your smartphone. It might never have occurred to you, but its

  • rectangular shape is no accident. And it’s actually what you want it to be. Rectangle

  • is the most convenient shape for a screen. It has an orientation, so you can flip your

  • phone all you want and it will adapt. Imagine that with, say, a round-shaped displayyou’d

  • have to always turn it in your hands until the top is where it belongs. Ugh. Next, it

  • fits into your pocket nice and cozy: the pocket is deeper than it is wide, so a phone longer

  • than it is broad will sit there perfectly. A square or circular phone will be more of

  • an inconvenience. Then again, a rectangle is much easier to handle. It fits in your

  • palm, and it feels better than a circle or a square. And finally, were used to having

  • rectangular things all around us: pictures, sheets of paper, books, photographs. Having

  • round-shaped screens wouldve been justweird. Still, there have been attempts to

  • create circular and square smartphones, but as you can guess, they didn’t get on.

  • Ever tried taking a photo of that striking moon on your smartphone? If you have, you

  • know what disappointment is. Yes, that little blurry whitish spot is the same beautiful

  • celestial body you see in the night sky. Your smartphone camera is just not light-sensitive

  • enough to capture it in its full glory. Manufacturers trade extra-high quality of photographs for

  • easiness of use, given that the average smartphone user doesn’t even need professional pictures.

  • So if you want a breathtaking shot of the starry skies, better get yourself a DSLR camera

  • with a special lens. Most smartphones now have both rear and front-facing

  • cameras, but they differ in picture quality a lot. This is because a higher quality camera

  • requires more space inside the phone, and manufacturers choose to install a smaller

  • and cheaper camera in the front of their devices to save that space. Instead, they up the performance

  • of the smartphone itself, which is a good trade-off, if you ask me. After all, the front

  • camera is mostly used for selfies, and it’s not like youre gonna print them on a poster.

  • When you turn your phone or computer off and then on again, the booting process can seem

  • awfully slow. Why can’t it just start up immediately, right? Well, when you switch

  • off your device, it dumps everything from its short-term memory. Think of it as hitting

  • your gadget hard on the head: it forgets everything you did with it and has to remember it again

  • upon boot-up. So it takes time for the device to wake up and start functioning at its normal

  • speed. Many modern smartphones have had their headphone

  • jacks removed. There are two reasons for this: first, without a 3.5 mm jack at the top or

  • bottom of the phone, you can make the device itself much thinner because it’s now by

  • far the thickest part of any phone. And second, water resistance is trending today, and a

  • headphone jack is a gaping hole in the body of a smartphone. Naturally, water can get

  • in there easily, so getting rid of the jack allows for making the phone waterproof.

  • Taking photos in the dark with a flash, you mustve noticed your smartphone flashes

  • several times before making the actual shot. Remember those horrid red eyes in old photographs

  • made on film or digital cameras? That happened exactly because the camera flashed only once.

  • In the dark, the pupils of your eyes become larger, trying to catch more light to see

  • better. And when they reflect the camera’s flash, the red-eye effect appears. With smartphones,

  • the first short flash makes the pupils contract from bright light, and only then the device

  • takes a shotand you don’t resemble a horror movie creature anymore. At least

  • your eyes don’t. Hey I’m kidding.

  • Hey, if you learned something new today, then give the video a like and share it with a

  • friend! And here are some other videos I think you'll enjoy. Just click to the left or right,

  • and stay on the Bright Side of life!

Hey, I bet youre so used to a smartphone in your hand that youve never even asked
