Unveiling the Most Common Bugs Encountered in Mobile App Testing

Bugs Found While Mobile Testing

Mobiles or smartphones are one of the highly used devices these days. That’s the reason why mobile app development has been increasing day by day. Whenever any mobile app is developed, it has to undergo several processes like designing, coding, testing, and implementation. One of the significant processes that ultimately ensures the smooth and efficient functioning of that mobile app is, app testing. Mobile App testing plays a crucial role in the proper and smooth functioning of a mobile app.

The testing phase completely ensures that your mobile app meets all the quality standards as well as performs up to the mark as per the user’s requirements. It involves a systematic evaluation of the app’s performance to know, whether the app is functioning efficiently and whether each and every feature of that app is working properly.

However, despite texting the app’s functionalities, Usability, compatibility, and security some of the bugs in the apps are still not removed even in the final products.

In this blog we are going to discuss different aspects of Bugs, exploring some of the most popular bugs to make you aware of the removal of those common bugs in mobile applications.

Here we will be discussing different aspects of the bugs and also the methodologies to mitigate those bugs with efficiency.

What Are Bugs In Apps?

The Term “Bug” refers to any sort of error that arise during the development process of a mobile app, causing functioning issues in mobile apps. These bugs in apps are classified using two different cases that are the best and the worst case.

Using the best case the mobile application might only affect the performance of that mobile app like the increase in the load time, delay in redirection as well as many other such issues. Coming on to the worst case the mobile apps might face some abnormal crashes as well as the app will sometimes stop working on the user’s devices.

These bugs originate in the source code sometimes when a developer performs coding for developing any mobile app. Even sometimes still after the rigorous testing standards these bugs are not removed from the code or the program design. These bugs are only encountered during the testing phase of the mobile application by the tester or when any of the users are using that application.

There are different types of bugs that are experienced by the users that are using mobile apps out of which we will be discussing some of the major sorts of bugs that are confronted by almost all the mobile app users. Almost every mobile app development services company in USA are spending a lot on removing bugs and errors from their mobile apps.  

Different Types of Bugs

UI/UX Designing Bugs: One of the most prominent bugs that arise during the mobile app testing revolves around its user interface or UI like the issues with the app’s layouts. These bugs are responsible for providing the users with the worst user experience affecting the app’s usability. These user interface bugs include the errors like inefficient responsiveness of mobile apps, incorrect font size, overlapping content as well as improper alignment.

Cross-browsing adaptability bugs: It restricts the versatility of an application browser and it should be eliminated to guarantee that clients can increase the usage of a browser program, simply by utilizing a web application without any issues. So whenever any application needs to access the cross-browsing capabilities then this bug makes the application respond improperly in multiple browsers resulting in improper functioning of the mobile app.

Form validation bugs: When you use characters say special characters, but the limitation to fill a form doesn’t let the user use it completely even after filling right information, then an error occurs. Sometimes these errors or bugs might prevent your business from getting conversions. This is considered one of the major forms of bugs that should be immediately removed from the mobile app, to ensure its proper functioning.

Tapping/clicking button bugs: A basic catch can cause a difficult issue on the off chance that you don't deal with the chance of quick touch taps. This can be very tiring specifically with those applications where we make payments such as banking and transaction wallet applications or in the message apps. Usage of tap buttons will be more, hence there should be no error.

Crash after tapping on a button: These resemble time bombs working as a button hidden inside the appearance of the application. At the point when the client squeezes that button, the application crashes. It is considered one of the most common bugs in mobile applications that affect only a particular functionality of any mobile application. This hidden bug only activates immediately after the user clicks any of the buttons present in the mobile app.

Functional Defects: The functional defects or functionality bugs consists of a wide range of issues starting from the mobile application crashes to the app freezes or any of the unexpected exceptions occurring in the mobile apps. It totally affects the ability of all the mobile app users in performing their desired actions. For avoiding such errors or bugs the testers must run or execute several test cases, completely validating all the input/output behavior of that mobile app.

Networking connectivity Bugs: Mobile Apps completely depend on the connectivity of the networks for delivering their user's various functionalities like data synchronization, and real-time updates. Just because of these app bugs sometimes the network connectivity is interrupted, after which the users don’t get access to some of the functionalities that are only accessible only when the network is connected.


Mobile app testing is an indispensable part of the mobile application development lifecycle. That helps the developers to deliver their clients with bug-free and seamless mobile apps. In this blog, we have discussed, what are the bugs in apps and how to test an app for bugs. By understanding the most common bugs encountered during mobile app testing and implementing comprehensive testing strategies, developers and testers can improve the quality of their apps, providing users with a reliable and enjoyable mobile experience.
