How to reduce eye strain while using the phone at night?

If you often go to bed at night with the phone, would you like to read an article from the Do You Know Tech Blog for the last time that day, I suggest you apply the advice from this text. Just like computer monitors, phone screens emit artificial blue light that bothers our eyes, especially at night when that screen is the only source of light.

If you've been following this blog for 6 years, you may remember (and probably won't) that I wrote an article about a Windows program that reduces that artificial blue. The name of the program is "F.lux" and if you haven't heard of it yet, read the article here. There you can also see graphs of how much the colors are shrinking, and why that blue is harmful at all if that interests you.

There is the same solution for the phone in the form of applications or phone settings. I will show you several ways so you choose the one that suits you best.

Android

If you have Android, then you belong to the group of happier people because you have more options. Android 7.0 Nougat has this option built-in, and if you have a lower version of the system then you can choose one of the free apps.

Integrated option

I can't tell you exactly where each phone is, but I can give you an idea. It is mostly found in the screen settings when you open the phone settings. The option is called "Blue light filter" in most cases. This is what it looks like with the Galaxy S7 phone with the Android 7 Nougat system:

Integrated option

As you can see you have options to adjust the intensity of the filter and when it will turn on (if you want it to turn on automatically). So you can set "from sunset to sunrise" or manually select a period.

You can add a quick (de) activation button in the quick action panel (when you drag notifications twice).

Applications

You have several options, and these are more popular and free applications: Blue Light FiltersFilterTwilight. F.lux also has its own application (link) but requires ROOT.

iOS

This option is integrated into iOS 9.3 and later versions called "Night Shift". You can easily access it: Settings> Display & Brightness> Night Shift.

iOS

And here you have several options:

  • Intensity adjustment
  • Automatic on / off: sunrise - sunset
  • Turn on manually (filter stays on until dawn)
  • Automatic on/off: from - to hours

You can manually turn this option on or off from the Control Center.

You can manually turn this option on or off from the Control Center.

How to change IMEI number on Android phone?

IMEI is an abbreviation of "international mobile equipment identity" and each mobile phone should have a unique IMEI number. You cannot change this number with the operator, but you can temporarily change it on your device. It allows the operator to accurately identify your device and thus enable/disable network services. Also, you can use the possibility of changing the IMEI number, at least for a short time, if you know exactly what you want, but I leave those ideas to you because this is an educational article.

Mobile Browsers

The Internet on mobile devices is becoming more popular and has more and more users. As mobile internet expands, so do mobile browsers. Although the devices themselves already have built-in basic internet browsers, new browsers are constantly appearing. The reason is that each of the programs brings something new and useful. For example, Opera Mini is most popular on older phone models that use Java applications, while on Android platforms Chrome , Firefox ,  Dolphin , and xScope are more represented.

Google AI game recognizes and learns what you draw!

Artificial intelligence (AI) is quite popular nowadays and is being used more and more intensively. Google has, I can say, the most developed so far and is available to end-users (at least one part).
