I need an experienced tester who can enrol 15 different, real smartphones in a Google Play Console closed track and keep the build installed and active for a full 14-day window. No virtual machines, emulators, or rooted phones are allowed; each device must be physical and used under normal conditions. The core requirement is simple: make sure the app stays installed, opened, and exercised on those 15 phones throughout the two-week period so I can collect retention, crash, and ANR data straight from Play Console. All devices must be smartphones; tablets are not part of this run. I’m flexible on Android versions as long as they’re reasonably current and the mix covers what you already have in your pool. Deliverables • List of the 15 smartphone models and OS versions before we start • Confirmation of enrollment for each tester account/device inside the closed track • Brief daily check-in (one sentence is fine) confirming the build was launched and used • Final summary after day 14 noting any crashes, usability issues, or unusual behaviour you observed If you already manage a bank of real Android phones and have run closed tests via Play Console in the past, this will be straightforward. Let me know your device lineup and how soon you can begin.
