📱 The Strange Mobile Bug

Yesterday, our testing team worked on a new mobile application.

I installed the latest version on several devices. First, I tested the Android version. Everything worked normally.

Then I changed the screen orientation from portrait to landscape mode. Suddenly, the application crashed.

I restarted the device and repeated the test. The same problem appeared again.

Next, I tested the app on an iPhone. Surprisingly, the bug did not appear there.

Later, the developers investigated the issue and fixed it.

After the update, the performance improved significantly, and the application worked correctly on all devices.

The testing session ended successfully.

📖 COMPREHENSION QUESTIONS

Who fixed the issue?
How did the performance change?
