Provide a managed release-certification service using a maintained pool of real Apple and Android phones and tablets. The customer supplies its critical workflows and release build; testers execute a repeatable device matrix, document failures with recordings and reproduction steps, and verify fixes. Begin as a hands-on service, then productize reusable test plans, device selection, release gates, and recurring certification.

The evidence spans older device transitions and current releases, indicating a durable compatibility problem rather than one temporary regression. Frequent operating-system updates, expanding screen formats, and continued business use of tablets increase the cost of incomplete device testing.
