Quality Assurance plays a vital role in software development. It helps the company in two ways:

1. Deliver a high-quality product to your customers.

2. Achieve an improved understanding of your user base.

Our dynamic QA team at Kualitee examines projects on various platforms, devices, and browsers. Furthermore, companies use an effective bug tracking tool to resolve such kind of issues.

Keeping this scenario in mind, we have compiled a list of bugs that appear in mobile and web applications. This will enable you to spot bugs when you are developing your own app.

1) Browser Adaptability

One of the most frequent problems is an app’s browser adaptability. It is the responsibility of the QA team to test the application on various browsers.

User experience and preference are given lots of importance while deciding which browser must be given priority during app testing.

Developers have pointed out that the most challenging browsers to work with are the older versions of Safari and Internet Explorer.

2) Authentication Fields

Such errors occur if:

•    You enter unacceptable characters into your app’s authentication fields.

•    You surpass the greatest files length.

However, these bugs are not given so much importance because they are not that severe.

Until now, in some cases, it probably means life or death for your app if you have wrong or missing field validations.

It’s good to limit the number of characters allotted to fields like phone number, zip code, and state or city name.

3) Date Control

Some apps use age restrictions, i.e. dating sites. We have uncovered bugs related to date control, mostly found in forms used for editing a user profile.

In such cases, QA applies a boundary value analysis for better testing coverage. Omit software testing, this means we focus on testing the boundaries between partitions.

If you are testing to make sure the date controls work properly, then you have to set up test cases that cover the dates.

4) Page Layout on Various Screen Sizes (Resolution)

Find out what browsers and devices your target audience is using the most and focus on these devices during testing.

We have witnessed complications arise with certain sorts of screen resolutions for various apps. This can't be defined, but this problem appeared when we recently tested a web app on a 4-inch screen.

5) Software to End User Communication Error

By not creating user-friendly software, you create a problem for your app. All the things that your user is searching for must be accessible on the screen. You should be very clear about the usefulness of the menu on the homepage and the help section. Make sure that your user knows how to use the app.

6) Button Clicks Leading to App Crash

This bug is likely to be found in all mobile apps. It's a time bomb. It is hidden somewhere behind the buttons that are not pressed by the users. However, the app functionality is messed up when this button is pressed.

Buttons that are not crucial for the running of the app can often be overlooked by developers. Such buttons might be found in an app’s profile editing mode, account settings, or used for adding pictures to a user's profile.
