Apps in Smartphones

Let’s face it: on our wonderful smartphones, we install dozens of apps and games, but only a few of them are used regularly. Many apps are left unused and just clutter the phone’s memory. Right – they clutter it and thus slow down the phone’s performance while occupying valuable space.

Why remove unnecessary apps at all?

There are two main goals: freeing up space in memory and potentially speeding up the phone. The first one is obvious and easy to achieve – by removing apps and related temporary files, we gain a significant amount of space.

The second goal is a bit harder to achieve. If the phone is really cluttered, freeing up space allows the system to better manage the space.

Although file fragmentation matters less with UFS or eMMC memory, if we have a cheap phone, it most likely has slow memory with fewer input/output operations per second (IOPS). If there is very little free memory, the system will have to cram data into every available space, and some files may not fit at all. This situation can slow down the smartphone, which is definitely undesirable.

That’s why it’s worth removing apps you don’t use and cleaning the phone’s memory to get rid of junk files.

How to Uninstall Apps in Smartphone Settings

There are two main approaches to this. The easiest and quickest way is to hold your finger on the app icon until a cloud or menu with options appears. In this menu, select "App Info" or "Information about the app."

This will take you to the system settings for the app where you can uninstall it right away. It’s a good idea to remove the app’s data from memory first, but it’s not always necessary.

Examples of "Questionable" Apps in Smartphones

• Vibrator Strong – This app does exactly what you think. You can adjust the vibration strength, lock the screen to hold the phone better, and choose from several vibration modes.

• Reface – Put your face in a movie – Want to look like Leonardo DiCaprio, Ariana Grande, Rambo, or even Mona Lisa? This app lets you do it.

• Poop Map – Been here, did my business – This is not a joke, it’s a serious social app. It won’t be funny when you need to use the toilet in a new city. The community will tell you where it’s "clean though…”

• Cat Sounds – This app seems perfect for cat lovers. If you like the sounds made by these pets, it has 100 sound variations.

• Pregnancy Test – You won’t find out for sure if you’re pregnant, but you can check your symptoms. The app asks questions and shows a few possible answers.

• NOTHING – As the name suggests, this app does nothing. When you launch it, you just see a white (Android) or black (iOS) screen.

• Fan – On hot days, an app that cools down seems like a dream come true. Unfortunately, it must remain just that – a dream. Why? The "Fan" app only imitates the sounds of a fan.

• Death Calculator – Based on your gender, birth date, name, and BMI, this app predicts your date of death.

• Urine Check – This app checks whether your urine color is okay.

• Ghost Radar – This app helps adventure seekers check if there are ghosts, spirits, or monsters nearby.

...and many other strange and useless apps.

You will work in groups. Each group will play the role of a company that services mobile phones and smartphones.

A client has approached you, requesting to clean their phone of unnecessary and cluttering apps. However, they will choose only one company.

Prepare a presentation to convince them of your offer, which will explain how to clean the phone of unnecessary apps while also recommending how to use and choose apps to customize the phone to meet the user's needs.

Remember, your potential client is demanding. They expect not only the removal of unnecessary apps but also advice on which apps to use and which apps are detrimental to them. The presentation should answer the following questions:

• How to remove unnecessary apps

• What security measures in smartphones prevent the installation of unnecessary apps

• What criteria to follow when installing apps on your phone

• Examples of the most useless and harmful apps for phones

• Are all apps safe for smartphones

To answer these questions in your presentation, you need to thoroughly understand the principles of installing apps on smartphones and explore the apps available for phones.
