Hi there, I noticed a slight mismatch in your description—the opening paragraph asks for app-level manual functionality and exploratory testing, while the detailed bullet points outline telecom-level field testing, RF optimization, chipset logging (QXDM/QPST), and 5G/LTE protocol validation. I can help you with either direction: - If this is strictly for a mobile app release: I’ll run structured exploratory and scripted functional tests across various iOS and Android devices, edge-case scenarios, and network conditions (5G, Wi-Fi, weak signal) to catch regressions and report detailed defects via JIRA. - If this requires deep telecom/RF field testing: I can handle firmware flashing, protocol stack validation, drive testing, and log analysis using QXDM, QPST, and Wireshark to ensure carrier compliance. Could you clarify whether your primary focus for this release is the mobile app's user interface and feature logic, or the underlying device RF and protocol layer? Once you confirm, I can jump right in. Looking forward to connecting! Regards, Vijay
