The abundance of Android devices with different screen resolutions, features, formats and so on makes hardware compatibility a problem. This may be considered a limitation: for example, for devices with no fingerprint sensors, it is impossible to implement this authentication type. However, we are skilled enough to offer multiple authentication methods to use the functionality of the device at its maximum. As far as the growing number of Android OS versions available simultaneously, it takes slightly more time for app development, testing, and improvement. However, our mobile development team knows the nitty-gritty and has the necessary tools to prevent malfunctions and bugs.

It’s impossible to answer without a valid review of the project, its functional and non-functional requirements. Although Java is mature and quite a lot of Android app development tools and frameworks still don’t support Kotlin, in some cases Kotlin-based development is more straightforward, can be a rational choice for fast prototyping and can simplify code maintenance.

The lack of strict app launch guidelines for Android development combined with the lack of development expertise facilitates hacker attacks. For the past 18 years of mobile development, we have accumulated enough expertise in encryption technologies, which helps us avoid even minor vulnerabilities in the matter of security.
