Introduction

As per Wikipedia,

"Android is a mobile operating system developed by Google, based on the Linux kernel and used for touch screen mobiles, Smartphones, and tablets. Google has further developed Android technology for televisions, cars and for wrist watches, each with a unique interface. Android is also used on notebooks, games, digital cameras, and other electronic devices".

Android has been the bestselling OS on tablets since 2013.

Android has following launches of new platforms including,

Explanation of some of the main problems identified

Description
1- Overheating	Overheating is a side effect of Android devices mostly caused due to high utilization of ram and also due to 3D games.
2- Slow Performance	· It's performance is slow due to bad memory management.· Background running apps.· Internal storage is full which slows down the mobile performance.
3- Security Issues	Cybercriminals have increasingly targeted Android-based and other mobile devices with SMS Trojans, Malwares, and Viruses. Specifically, these threats can be divided into several categories: Web-based threats Application-based threats During the year, Internet security experts identified more than 35,000 malicious Android programs. And in 2012, 99% of all mobile malware was designed to target the Android platform.
4- Android Not Reading micro SD Card	When we use Android Phones for a quite a long time, we may find that the internal storage is full which also slows down the mobile processing speed. To release the internal memory, people tend to insert an external SD card into the Smartphone, in the meantime, to increase the storage of the phone. However, some users usually complain that the SD card can't be detected or read by the device.
5- Gallery Images are not shown	One of the main problems in Android OS is sometimes gallery images are not shown.

Role of SQA in problem solution

SQA helps us to find solutions and solve problems that occur in the Android operating system.

A technique named Fishbone diagram helps us a lot to know what is the cause of the main problems.

Possible Solutions

Overheating

To avoid overheating problem, the following precautions are used:

Always use original battery and charger
Minimize the use of 3D apps and games on low processer mobiles
Always use authorized apps to avoid any problem in OS

Slow Processing

Slow processing is mostly due to the high rate of work on the Operating System. Due to slow processing mobile phones often get stuck and do not respond properly. Possible solutions are as follows.

Use any cache cleaner to delete extra or temporary files.
Use Memory management software to manage internal or external Memory.
Sometimes overcharging or overheating causes slow processing so always plugged out the phone when a battery is full charged.
Use small or appropriate antivirus software’s to remove malware or Trojans.
Don’t play with Operating system files.
For developers always turned off USB debugging mode when their development is done.
To ensure good performance by OS close extra background running apps.
Turned off Bluetooth or WIFI when they are not in use.
Don’t play high graphics or large size games. (If you want to play than ensure that your RAM is enough to play this type of games)

Security Issues

As we discussed earlier, there are two types of security threats. So here we discuss how to tackle these threats.

App-Based Threats
These threats are mostly due to unauthorized apps so, the following precautions should be taken.

Always use authorize apps to reduce any security issues.
Before the installation of any app. carefully read about all the permissions that the app wants. So you are clear about the accessibility and scope of the app.
Don’t open those files in which operating systems warn you to open.

Web-Based threats.

These threats are caused by the use of the web.

Use an authenticated web browser.
Use ad blockers.
Cybercriminals mostly target android apps so always use the site with Https protocol to ensure more security.

Gallery Images are not shown

This is one of the common issues in android operating systems and in android phones. When gallery images are not shown in your phone then check whether your internal memory has enough space to show these images. Also, take a look at images in the following ways.

Ensure that the image file is not corrupted.
Image size is not so large to open.
Image format must be supported by Android OS
Go to image properties and uncheck hidden checkboxes (if checked).

The following things should be checked by the SD card or slot of the SD card.

The SD card is not broken.
The card slot is not rusted.
Wire in card slot is not twisted.
The SD card is formatted properly.
Android phones must support that type of SD card.

Android not reading Micro SD card

The following things should be checked by the SD card or slot of the SD card.

SD card is not clean
There some malware in SD card
OS does not support that type of card
The SD card is not broken.
The card slot is not rusted.
Wire in card slot is not twisted.
The SD card is formatted properly.
Android phones must support that type of SD card.

Case study of problems

As we discussed earlier, we have come to know that most problems that occur in Android OS are due to apps. These apps cause problems in many ways like they spread viruses in operating systems and unauthorized apps harm the Android OS. Excess use of apps slows down processing speed and affects performance.

Android users may also face problems like images are not shown and sometimes mobile phones get stuck or SD card is not detected. Other problems include USB connection problems that Android phone is not connected to Windows PC.
