Mobile Device Specifications¶
If your project plans to do a large acquisition of devices, it is good practice to delay the bulk of the acquisition as much as possible. The idea is to get the best device that you can afford. Technology, and particularly mobile devices, evolves very rapidly. A given model is normally refreshed on an annual cycle, giving consumers access to significant technical improvements year-on-year, but with similar price point. More recommendations on acquisitions can be found in the Scale Up section.
Specifications for mobile devices to use the DHIS 2 Android App deployment are included in the following table. Please, note that these recommendations are very generic as performance of the device will be highly impacted by your configuration. For example, having a tracker program with hundreds of program rules will require a more powerful device than an implementation where you are only collecting a small set of aggregate data.
In general terms when having to choose different versions of Android aim for the higher. Also, acquiring devices from well known brands might be an indicator of having better after sales services like repairing and/or updates.
