According to studies, there are currently 2.9 million mobile apps in the Google Play store and nearly 2 million in the Apple Store. With 5.1 billion mobile phone users, about 90% of the users’ mobile usage is time spent on different mobile apps. So it becomes essential for enterprises to ensure that their apps do not have any bugs and glitches before the rollout.

However, achieving perfection in terms of user experience is not an easy task. It is an iterative process, and there will be trying & testing to identify the bugs on mobile apps and resolve them. This guide will discover the iterative testing phases to identify the bugs on mobile apps and resolve them on a real device cloud.

So the question is, how to find bugs in an app?

Why test Mobile Apps on Real Devices?

Before moving to the testing part, it’s important to understand the need to find bugs on real devices.

  • When testers and developers test their apps on real devices, it shows how users experience using the mobile application and the problems they face in real user conditions
  • It helps to find bugs more effectively and provides complete transparency of application performance. 
  • Using emulators/simulators will not be a reliable solution for testers because it comes with various limitations, such as the inability to mimic battery states or cellular interrupts. 

BrowserStack App Live is specifically designed for testers and developers to conduct real device cloud testing in the simplest manner.

Common Bugs found in Mobile Apps

Before launching the mobile application on Play Store or App Store for public use, it’s essential to check how to find bugs in apps, and for this, here are some most common bugs that can be easily found and resolved on your mobile application. 

Here are some common bugs found in mobile applications:

  • Crash After Tapping on the Button: The application crashes whenever a user taps on a specific button, and it’s the most common bug on mobile apps. This hidden period bomb activates whenever a user clicks on the button. So it’s essential to find this particular bug and resolve them. Find out 5 Reasons Why Mobile Apps Crash.
  • No Progress Indicator: No Progress indicator is one of the common bugs found when a user uses an application and wants to download or upload any file, but it’s not showing any progress or process when a user clicks on the button. 
  • Slower Response: Speed is the most common bug that needs to be considered for mobile applications. If the mobile application takes more than 5-10 seconds to open or process any requests, it can be a major bug that must be resolved.
  • Different OS Support: A mobile app should be designed to support Android and iOS. Many mobile applications have these bugs that do not support other OS platforms, hence losing out on market adoption and revenue.
  • Portrait & Landscape Orientation: Mobile applications should be easy to access from both angles, i.e., portrait & landscape views. Another common bug that needs to be considered while improving the readability.  
  • Error Handling: When a user is accessing the mobile application, and suddenly the screen shows “error 404” or crashes, it requires improvement and increases the efficiency of the app.
  • Push Notification: Push notifications are the medium to engage with mobile app users and work according to the user’s command. But sometimes, the application doesn’t send the user’s request and does not work properly, and this bug should be resolved. Learn how to test push notifications on real devices.
  • Native App Permission: Some permission bugs may not allow users to access the mobile application. So it’s important to understand the importance, resolve the permission issue and allow users to use the application with all permissions, including security, request, SMS, camera, video, and audio. 

7 Tips to Find Bugs on your Mobile Apps

How to identify bugs in an app? is the most asked question that every tester & developer wants to know. Here are 7 valuable tips that help to find bugs in mobile apps: 

1. Application Overview

Before starting to find bugs on any mobile application, ensure you’ve complete knowledge and understanding of the workings of that particular app flow. Once you have an idea about the design and working mechanism, it’s easier to find buggy areas where bugs are and plan accordingly. 

Testers must check that every function of the app is performing exactly as expected. Functional Testing is a wide category that comprises smoke testing, sanity testing, regression testing, usability testing, and so on. 

2. Develop Test Cases

Once you’ve found all the bugs on your mobile application and created a complete detailed report, start developing and prioritizing test cases that they would like to dive deep into.

3. Automated Parallel Testing

Automated testing tools make it easier to do parallel testing on the mobile application without performing any manual tasks. Parallel Testing is a process to leverage automation testing capabilities by allowing the execution of the same tests simultaneously in multiple environments, real device combinations, and browser configurations.

4. Obtain Customer Feedback

Gathering customers’ feedback helps in finding bugs from a neutral and non-biased perspective. These users have prior experience in using the application, and they know where the shortcomings of this application are. Learning from feedback can be the best way to find bugs in apps and improve them accordingly.

5. User Interface (UI) Testing

UI testing is used to analyze the complete performance of a mobile application from start to end. With this testing, you can learn how to find bugs in apps, where the application is lacking, or if it is difficult to access any features.

6. Check Performance under Limited Storage

Sometimes mobile applications start hanging or may become slower because of the lack of storage space in mobile phones. So it’s essential to check the performance of your mobile application and see if there is enough space. If not, you need to find a bug that can be resolved by optimizing the storage.

7.  Conduct Repeated Testing

After resolving all the bugs in the application, it’s important to save the changes and again check bugs several times in the updated application for better improvement. Allow the users to use this updated application and get genuine feedback to improve accordingly. 

Regression testing is a better alternative to this and should be implemented by every product-based company looking to scale faster.

There you have it. These seven useful tips will help you improve the testing efficiency and find bugs more effectively. Once you’ve understood the common bugs and 7 tips,  it’s time to implement these tips and find bugs in your mobile apps.
