If you have used a transparent smartphone cover, then you might have experienced the smartphone cover/case turning yellow in color problem, right. Why does the smartphone cover/case turn yellow, and is there any way to turn the yellow cover into transparent again? Why Does The Smartphone Cover Turn Yellow? Smartphone covers are made using Silicone which is considered a plastic and rubber hybrid which makes it flexible and it is cheap too. Silicone is a substance that changes its color(mostly in yellow) over time. And there are also mainly three things that increase the rate of making transparent phone covers made of Silicone to the yellow phone cover. They are: Heat Makes The Phone Cover Yellow Whenever your smartphone is exposed to direct sunlight or when you use a smartphone, the phone heats. In this case, some chemical reactions happen in the transparent smartphone cover made of Silicone. The Silicone cannot resist heat or direct sunlight which contributes to turning the transparent...

Let’s be real — the moment you tell someone you’re learning to code, someone will say, “Whoa, you must be good at math, huh?” And if you’re like me (and probably 90% of the world), you immediately think: “Uh oh… I suck at math. Am I screwed?” The short answer? Nope. Not at all. Coding ≠ Math Class Here’s the truth that nobody told us in school: You don’t need to be a math genius to be a good coder. In fact, most web developers, app creators, and even software engineers barely touch “hard” math in their day-to-day work. You’re not solving calculus problems. You’re building cool stuff. Writing logic. Making things work. What You Actually Need Instead of Math If you’re bad at math but good at things like: Solving puzzles Breaking big problems into small steps Paying attention to details Being curious and googling solutions …then congrats. You already think like a progr...

Right now, In a smartphone, you will get a 48MP Camera, 64MP Camera, 108MP Camera, and so on. But, Does this number of megapixels improve the image quality? What is a Megapixel? Megapixel means a million pixels in an image. Pixel is the small dot or square on the image. By combining millions of pixels, one image is formed. 1 Megapixel = 1 Million Pixel, 2 Megapixel = 2 Million Pixel, 12 Megapixel = 12 Million Pixel, 48 Megapixel = 48 Million Pixel, 64 Megapixel = 64 Million Pixel, and so on.   Does More Megapixel equal better image quality? No. A Megapixel is just a million pixels in an image. Many other factors also matter while capturing an image like Image Sensor, Aperture, Megapixel, Lens, and Software.    If you have a 108 Megapixel Camera with a small image sensor and a 12 Megapixel camera with a big image sensor. Then, The second one will have better quality. It's because, in a big image sensor, the pixel size is bigger. If the pixel size is bigger, it can capture...
