What are the types of bugs found during mobile application testing?


When testers are testing mobile applications, they can find errors and bugs. A bug displays a defect or failure in the product or framework that companies create. Companies must spot and fix the bug in the product or framework.

What are the different types of bugs found in a product or framework?

There are three types of bugs found in a product or framework, including:

1) Application-specific bugs are linked to the application’s business logic. Companies can find it challenging to detect them. Extensive knowledge of applications can be beneficial. It is also essential to note the test cases for application-specific bugs. 

2) Platform-specific bugs – every mobile platform (Android, iOS) has bugs linked to the operating system’s working.

3) Explicit bugs identified with the crucial components of the application design.

What are the types of bugs found in mobile app testing?

The most prominent application market in the smartphone industry is Android applications. Hence, companies need to discover and fix the bugs in the Android applications. Some of the most common types of bugs companies can find during mobile application testing include:

1. Crash after users tap on the button

It is a bug testers find during mobile application testing. It usually occurs with hidden buttons. It is similar to a time bomb. The buttons that are hidden inside the application are easy to overlook. When users tap on them, the application will crash.

2. Progress indicator

A progress pointer will inform a client that a particular activity is in progress (for instance, if they are downloading a song or uploading a profile picture on their devices). Sometimes, users will not have an advancement marker in their application. Without a progress indicator, users can tap on this button repeatedly, feeling that nothing has happened.

3. Possibility of tapping buttons repeatedly

A simple button may result in a significant problem when users do not handle the possibility of fast clicks. Companies should test this case with care in those applications where users will make payments or send messages since users could repeat the action many times. For instance, users can accidentally tap the “Pay” button twice, and, as a result, they will get charged twice.

4. No error handling

A critical thing company must remember is that they always display an error to users. Showing errors straight from the server could give the programmer vital information but not the end user in every case. Ultimately, companies create the application for users, not programmers. Therefore, companies must always display invalid login credentials instead of 401 (unauthorised error).

5. Push notifications

It is challenging for companies to make push notifications work initially. Push notifications are a crucial communication and engagement channel between an application and the user. Therefore, companies must ensure that they work correctly.

6. Skipping selector on buttons

Companies must remember that all taps must have selectors. It will help users notice that they have tapped a button. Otherwise, a click could be duplicated many times.


Testers can discover bugs during mobile application testing. Companies must find and resolve the bugs before releasing the applications to the users.
