Challenges
and learnings
Notifications posed one of the biggest challenges because they were a key functionality and were supposed to arrive to the user under any circumstances. In this we went to the limit of what operating systems allow us and solved the various challenges associated with the advent of customized notifications. For example, how to deal with silent mode and DND on different versions of the system and on phones from different (mainly Chinese, which do not have official representation in the Czech Republic) manufacturers. The challenge was also the implementation of custom sounds for notifications and exporting them to the phone's storage. When testing this feature, it then sounded like a firehouse in the office. However, with the help of careful testing, we were able to detect and correct these errors.
