To absorb water, rice grains have to be in direct contact with it.

Even worse, when rice starch gets mixed with liquid, it produces a paste that can gum up

Experiments showed that after 48 hours, rice still managed to absorb only 13% of the moisture

Modern phones have solid-state drives that don't need magnetism for storing data.

What a magnet CAN do is interfere with your phone's compass.

But then your navigation apps, like GPS and all kinds of maps, won't be able to determine

your position, and game applications won't understand your phone's orientation.

High-quality pixels are also larger, and fewer of them have to be crammed into a single picture.

Since the 4G connection is faster, most people believe that it uses more data.

But whatever connection you use, 5 MB of data is still 5 MB of data.

With 4G, you'll just need less time to download it.

faster, and you use more data in a shorter period of time.

After all, it saves your battery, and that's a good thing, right?

If your smartphone's screen is too dim, you'll have to strain your eyes.

And even though it's unlikely to lead to any permanent damage, you'll get headaches and

If your screen brightness is higher than 50%, though, you should keep it down a bit.
