Possible challenges before choosing this path.
Android background restrictions, privacy rules, permissions, device identifiers, and API behaviour change frequently and can break telecom app features.
Apps may behave differently across OEM devices, Android versions, SIM states, network types, screen sizes, and carrier configurations.
Carrier features, VoLTE, VoWiFi, IMS, APN, SIM behaviour, roaming, and provisioning can be difficult without telecom domain knowledge.
Carrier or OEM releases may require strict testing windows, lab validation, regression cycles, and fast bug fixes.
Improper handling of device identifiers, SIM information, call logs, location, contacts, or network data can create privacy and policy issues.
Developers who only know basic Android without telecom APIs, logs, device testing, and architecture may face competition from general app developers.
