Guides for hosting, maintaining, and monitoring CHT applications
Medic supports minor versions of the CHT Core Framework for three months after the next minor version is made available, and the latest minor of a major version for twelve months after the next major version is made available.
Once a version is no longer supported it will not receive any further patch releases and upgrading to a supported version will be required to resolve any issues you have.
It is recommended that all projects update regularly multiple times a year to get the benefits of bug fixes, security patches, and performance improvements. Being on a supported version also makes it easy to start using features coming in future releases. Most upgrades are quick, reliable, and easily adopted by users. Whenever an upgrade does require additional effort this will be outlined in the release notes.

If CHWs will be collecting GPS data, autonomous GPS sensors in addition to assisted GPS (A-GPS) for areas with poor GSM network connectivity will enhance the quality of GPS data collected. Autonomous GPS is usually labeled in terms of the supported navigation satellite system:
Devices with more navigation systems are more likely to get a more accurate location fix in varied locations. For example, Huawei Y5 has GPS specs listed on gsmarena.com as GPS: Yes, with A-GPS, GLONASS, BDS which makes it a good choice for GPS data collection.
