Common Bugs in Mobile Application: A Quick Overview

We're all human and make mistakes. That is why you require a QA team to double-check the most common bugs in mobile applications. If you're a surgeon, you can only rely on yourself, but our programmers have more assistance. QA assists you in delivering high-quality products to your clients and examines applications from the user's point of view.

Bugs that we encounter on a daily basis can be classified into three types:

  • App-Specific Bugs:  They are related to the app's business logic. They may be difficult to detect, so having a thorough understanding of the app will be extremely beneficial. It is also critical to document test cases for this type of bug.
  • Platform-specific flaws: Each mobile platform (Android, iOS) has its own set of bugs that are related to how the operating system works. 
  • Specific bugs relating to the app's basic architecture.

In this article, I'd like to concentrate on the third type of bug. They're the most common, but they're also the easiest to overlook. Let's take a look at the list of bugs in mobile applications.

Possibility of Tapping/Clicking Buttons Repeatedly

Let me introduce you to the programmer's flaw. If you do not account for the possibility of fast/rapid clicks, a simple click can prove to be problematic. Because the action could be done several times, this case should be tested with special care in applications where we send money or send messages. Consider the following scenario: You accidentally tapped the "Pay" button twice, resulting in a double charge.

Progress Indicator

It is also necessary to include a progress indicator to notify the user that an operation is in progress. There are many situations where actions last for a long time, and it is very desirable to show a progress indicator to inform a user that something is happening right now. This includes situations such as screen/content loading, long network operations on button clicks such as profile editing, image uploading, and so on. Consider a user updating their profile image by clicking the "upload" button. Without a progress indicator (during the image upload process, which may take some time), a user may repeatedly tap this button, believing that nothing has happened.

Portrait/landscape Orientation of the App

Have you ever tried switching the screen orientation and discovered that the present state of the application was not saved? In the Android system, for example, a specific screen element called Activity may be destroyed with screen rotations, resulting in the loss of its current state. As a result, all previously selected checkboxes or dropdowns may be cleared after the rotation. Although an increasing number of applications prohibit the use of a landscape view, this remains a problem in applications that support the horizontal view.

Push Notifications

It's difficult to get them to work the first time, but they're an important communication and engagement channel between an application and a user. It is critical to ensure that they function properly. Figuring out the solutions for bugs in mobile apps is critical in increasing usage.

Specify The Input Type

First and foremost, we must ensure that the correct keyboard type has been opened. It could be very useful for a user to see a keyboard type that is tailored to an input field type. For instance, in a phone number text field, we'd like to show the user a numeric keyboard, and for an email text field, we'd like to show the user a keyboard with the "@" character. Users, believe it or not, will be grateful. We should also pay attention to another very crucial component, which is the type of password input. Using a text field for a password is simply not safe. It's much easier to read a password over someone's shoulder than it is to read their keystrokes.

Page Layout at Different Screen Resolutions

As you may be aware, the number of requirements for the development of mobile applications is rapidly increasing. Device models frequently differ in terms of size, resolution, and operating system version. As a good QA, you must ensure that the application looks really good on all of these devices. Addressing the most common bugs in mobile applications is vital in a good user experience in the long term and will increase your mobile app usage.

Repeated Results

This one is specific to Android and is linked to how "ListView" works on Android. Essentially, each element that appears at the bottom of a list while scrolling reuses the view of the element that was just scrolled off the screen. This could result in both cells, the new one and the one that vanished, having the same data. Understanding this process is important because the problem is quite prevalent. 

Final Thoughts

All things considered, it seems reasonable to assume that the most common bugs in mobile applications mentioned in the article are both easy to detect and not that difficult to remember. It is critical to identify and resolve any issues before releasing the app to the general public.
