Most Common Bugs You’ll Find in Mobile Applications


Bugs are flaws in the production of an application that causes it to be abnormal. There are various types of bugs that ‘bug’ app developers and testers. Companies equip themselves with capable issue tracking tools that allow them to record and track bugs. In this article, we will list down some of the most common bugs.

Crash After Tapping a Button

This is one of the most common situations which usually occurs when there are hidden buttons and tapping the wrong one results in an application crash. It’s like a time bomb that explodes when the trigger is pressed. This triggering device is usually the button.

Push Notification

Push notifications are very important for communication and engagement. They connect the user and the application. A bug may cause these notifications to not appear. It can be hard to deal with these bugs for the first time. Nevertheless, they need to work properly.

Progress Indicator

The progress indicator helps the user to be patient. Without one, users may not know whether the task is completed, in-progress, or can’t be completed at all. Some operations may take time and users should know how much. The progress indicator is useful for operations like profile editing, uploading images, and a lot more.

Tapping Buttons Repeatedly

Tapping a button twice while sending a message or worse, making payments online can mean trouble. Developers must consider the scenario of rapid clicks while building the application to avoid any problem.

No Error Handling

Whenever an error occurs, the user must know about it. How? By displaying an error message on their screens. Make sure that the error message reveals important and useful information to the user. Any complex information can leave the user puzzled and unsatisfied.

Page Layout

Mobile devices come with varying screen sizes, resolutions, densities, and specifications. Mobile application developers must make sure that their application functions properly on all types of devices.

Specify Input Type

Always make sure that the right keyboard type is opened. A user might find it better to display a keyboard type adjusted to an input field type. For example, if the input field requires numeric values, the application should only show the numeric keyboard. It’s a simple, yet important aspect of an application. Another example is the password input field where the application shows the regular keyboard but the written password is displayed as dots. This is for security reasons.

Repeated Results

This bug is Android-exclusive. It’s basically when each element that reveals the button of a list during scrolling, reuses the view of the element that has just been scrolled off the screen. This may lead to a situation where both new and old cells have the same data. It’s important to understand this mechanism as this issue is very common.


Bugs listed in these articles are easy to detect via issue tracking tools but hard to remember. These bugs must be treated before the application is released to the final users. Developers should take a bit of time out to self-check the application for any errors and make life easier for QA teams.
