Device Changer

Device Changer is an LSPosed module that lets Android QA teams simulate device profiles at the app layer, identifiers, build fingerprint, OS version, and more, without needing a physical device lab. Teams use it for compatibility testing across Android versions and OEM skins, reproducing device-specific bugs from user reports, and testing fraud-detection or Play Integrity flows under controlled device conditions. Works alongside Magisk and Zygisk/ZygiskNext. Built for QA engineers and mobile developers who need broader device coverage without maintaining a growing pile of test phones.
