Open the bug reporting mode
Ask the people that gave you the app how you're supposed to open the bug reporting mode. Usually it's by shaking your device when you notice a bug, or tapping a dedicated button.
By the way, you can regularly report bugs while in your underground commute or on an airplane — you don't have to have internet connection.
Mark what's wrong
When the Report a bug mode opens up, you will see your screenshot. If there's a part of the screen you want to highlight, mark it with a color of your choice.
Once you're done, tap Next.
Then, describe the bug
Follow these 4 rules to describe a bug like a pro:
Your bug description has to be short and without emotions. Also, report just one bug at a time.
Do not write about any technical details:
what device you're using and which screen you're looking at
your app version
your internet status and battery level etc.
because people on the other end will have all that data automatically. 👌
Talk to your app admin and see which useful #hashtags you might put at the end of your bug descriptions to make them even better.
Leave your email address in its dedicated field, so that app developers can get back to you if required.
Examples of perfect bug descriptions
Color of the 'Exchange' button is yellow, but it should be green.
App froze while uploading profile photo so I tried to tap the 'Upload' button a few more times. Bug: Each time I tapped the 'Upload' button, the screen became darker, until it went completely black. #sprint9
When I select my email address, I don’t get a context menu to copy/cut/paste that I expected. #low-priority
Spelling mistake in installation instructions: 'at lease' should be 'at least'.
