US App Testing, Android

I'm currently in need of a lot of freelancer in US who can conduct comprehensive testing for my Android social networking app. The testing types required include:

- Functional testing
- Performance testing
- Usability testing

Suitable applicants should have a solid background in Android app testing, and it would be advantageous if you could highlight similar past work in your application.

Being a social networking app, it would be beneficial if you have previous experience testing similar types of applications. Additionally, your ability to clearly report issues and identify areas for improvement is crucial.

Superlative testing insights and having a keen eye for spotting flaws that impact the overall user experience are welcomed and highly valued. If you are an attentive, detailed-oriented professional with a history of effective app testing, I would be thrilled to hear from you.
