Mobile Device Selection

Choosing a mobile device for your CommCare project can be a hard decision.  The Dimagi team has worked to make this decision a bit easier by testing numerous different phone models and documenting their performance. This page will provide you with the results of our testing as well as some general guidance on selecting your device.

Please note that this page includes recommendations of mobile device models. If you are uncertain if CommCare is supported on a mobile device that is not listed on this page, Dimagi’s recommendation is to procure a phone and test it.

Considerations for Selecting Your Device

CommCare requires Android OS 4.1 or higher, with a preference for devices on the higher end for extended support. Consider the following when selecting devices:

  • Local Support: Ensure quick replacement or repair options, compatibility with local standards (characters, dates, voltages, plugs).

  • Accessories: Check for SIM card compatibility, particularly in tablets, which may have SIM or WiFi-only models.

  • Battery Life: Critical for rural areas with limited power access. Test battery life to match project needs.

  • Device Longevity: Verify if the device model will continue to be available and supported in the target region for the foreseeable future (3, 5, 10 years).

  • Cost: Assess if the cost is reasonable and comparable to other devices in the area to avoid theft risks.

  • Performance: Consider device speed, memory, screen size, and resolution for app requirements, especially for multimedia use or users with poor vision.

  • Connectivity: Ensure at least 2G network compatibility, along with GPS, GPRS, and WiFi. Confirm compatibility with local telecom providers.

  • Language Support: Verify support for all necessary languages for your project by checking settings and language compatibility. (Potential tool here: http://www.unicode.org/charts/)

  • CommCare Compatibility: After narrowing down options, test your application on a potential device to ensure optimal performance, including language support, image quality, audio, and video functionality within the app.

Mobile phone or tablet?

While tablets are slightly more expensive than phones and have equal or worse battery life, they also have several benefits for certain projects. Consider using a tablet for projects with:

  • Heavy data collection: Tablets, with their larger screens, can display more questions at once (around 6 compared to phones' 4), reducing the need to swipe frequently.

  • Extensive use of multimedia: The larger screen of a tablet makes it better for viewing images and videos.

  • Stationary settings: Tablets are suitable for less mobile environments. Their size makes them more conspicuous and potentially more at risk for theft.

  • No need for traditional communication: Tablets lack the capability for calls and SMS, which could be a limitation depending on project needs.

Recommended Devices

Below is a list of recommended devices from Dimagi. These have all been gathered through partners over the years. Please note that this list is updated on an irregular basis. As such, we suggest testing the phone to ensure it meets your project requirements before procuring multiple phones.

Recommended Android Phones

We have a large install base of users with phones from Oppo, Tecno, and Redmi, which are broadly available and currently free of any specific reported issues in our device catalog. Below are the three most popular phones of these kinds that are used with CommCare

  • Oppo CPH2271

  • Redmi 10A Sport

Samsung’s high end devices are popular and do work well with CommCare. They used to be our general recommendation, but we’ve found their mid-to-lower tier devices problematic. In some markets, we’ve had experiences where those phones have been custom rebrands of old hardware that work much less well than their less-prestigious and cheaper competitors, leading to potential issues with their lower end devices.

Phones with Known Limitations

The phones listed below all have known limitations, and may be associated with known compatibility issues with CommCare.  These phones may still be good options for a CommCare project depending on the projects needs. As with all phones not on our recommended phone list, we suggest testing the phone to ensure it meets your project requirements before procuring multiple phones. In addition, please keep an eye out for counterfeit phones.

Please note: Due to Google's revocation of Huawei's Android license, any Huawei devices produced after May 2019 would not support any Google apps including apps on the Google Play app store. As such, Huawei devices are not recommended for CommCare usage.

Multiple Infinix models

Multiple Tecno models

  • These models come with operating system processes that are configured to aggressively force close apps after navigating away from them even briefly. (While all Android phones use occasional force closing as part of their overall memory management strategies, these models go well beyond what other devices do.) Since CommCare forms can sometimes take a while to fill out and users may sometimes switch to other apps during the process of filling out forms, this can result in data loss. Workarounds:

    • There is a feature you can enable to auto-restore after a force-close so that the form state is not lost. (TBD)

    • Some devices come with a features on the Recents screen (the background screen that lets you switch apps) that lets you tell the OS you do not want it to force-close the app. On the Recents screen (with CommCare recently open), find CommCare and tap the lock icon in the top right corner to make it go from unlocked to locked. This may reduce the rate of force-closes CommCare experiences.

Samsung Galaxy Y

  • The sound recorder on the Galaxy Y improperly accepts the intent to record audio, and does not return the proper information to CommCare for audio recording questions. Workaround: A different sound recording app can be installed from the Google Play market to replace the defective stock application.
