TrackAbout's Support Policy Explained

What is TrackAbout's reasoning for supporting certain versions of iOS?

Apple releases new major versions of iOS (e.g. iOS 13 to iOS 14) each year. See Wikipedia History of iOS for the exact schedule.

TrackAbout must choose how far back to support major versions of iOS. As time passes, it becomes increasingly expensive and eventually impossible to continue supporting apps on old versions of iOS. Apple forces the hand of developers by dropping support for older versions of iOS from their developer tools.

iPhones and iPads are consumer technology, and the pace of change in the consumer space is rapid. Whereas rugged enterprise devices are typically expected to have a useful service life of 5 years, consumer technology generally has a life-span of 2-3 years.

TrackAbout is sensitive to the needs of its customers and does not wish to unduly prohibit use of the app by paying customers who haven't yet or cannot update their devices to the latest version of iOS.

Therefore, TrackAbout's iOS Version Support Policy balances these competing realities by:

• Supporting the last two major releases (back to the most recent dot version of the older OS). For example, if iOS 11.3 is the latest version, TrackAbout supports iOS 11.X and iOS 10.3, which was the highest version in the 10.x series.
• Prompting users periodically to upgrade from within the TrackAbout app when a newer iOS version is available.
• Increasing TrackAbout's minimum requirements 6 months after Apple releases a new OS. New versions of iOS typically reach greater than 80% adoption within 6 months of release.

Google Android Devices

Android Version Support Policy

Updated September 29th, 2021. This policy is reviewed quarterly.

The TrackAbout Android app is currently supported on Android devices running Android OS version 5.1 or higher.

Devices with non-supported OS versions will cease to get new updates of TrackAbout from their respective stores. They will always be able to uninstall and reinstall the last supported version from stores, but TrackAbout will only support the current application release.

Android Device Buying Guide

There are many Android devices on the market at many different price points. It's very difficult for TrackAbout to reliably recommend specific models and keep those recommendations up-to-date. So how do you choose?

We are going to discuss several important factors to consider when purchasing. If you are purchasing rugged devices, we recommend finding a trusted supplier, such as Supply Chain Services https://www.supplychainservices.com/ (US operations only).

Minimum Android Hardware Requirements

• A rear-facing camera with 2 megapixels or greater
• Minimum 1 GB RAM
• Bluetooth (for printing or external scanners)

Rugged Android Devices

If you want or need a ruggedized device, especially one with built-in scanning hardware (instead of using camera barcode scanning), then you need to choose a device that has been tested and certified with TrackAbout. See TrackAbout Certified Devices.

Intrinsically-Safe Devices

If you need explosion-proof devices for use around combustible materials, you do not have a lot of choices. Look first at vendor Bartec https://www.bartec.de/

Consumer Devices

First, you must meet the Operating System and Hardware requirements listed above.

Second, do not buy the cheapest devices you can find. We also do not recommend buying used on eBay or the like. The cheap devices will not perform well and will frustrate users. Used devices will have no warranty repair support.

We recommend buying devices in the mid-tier of price or above.

Do not buy an Android device that is more than one year old, as it will stop getting Android OS updates in another year or so, and at a certain point, will not be able to run the TrackAbout app due to aging out of TrackAbout's supported Android version policy.

Consumer-Grade Safe Bets

The current generation Samsung Galaxy devices are typically safe bets because they meet all the above criteria. They are flagship (top of the line) products with great specs and a great camera, which makes for excellent scanning.

Devices sold directly in the Google Store are generally safe bets, although as of this writing (April 2017) they tend to be expensive, flagship devices.

TrackAbout does not routinely test Android devices, so we can't make other more specific recommendations here.

Known-Bad Consumer-Grade Devices

Samsung Galaxy Note 4 - Our test device had severe camera auto-focus problems that made scanning very frustrating. There are widely reported problems with auto-focus on the Note 4. We attempted modifying "Metering Modes" under camera settings, trying Matrix or Spot settings, but it did not help.

Mobile Device Management

We recommend finding a MDM vendor who can help you deploy and manage your mobile device fleet. MDMs will help you lock down devices for security, and monitor OS and App upgrade compliance. If you desire, you can use an MDM to deploy the TrackAbout app installer after downloading the latest version from TrackAbout's APK share web site https://apkshare.z20.web.core.windows.net/

BYOD

For security and compliance reasons, we do not recommend a BYOD strategy for field workers. As a company, you'll have no control or visibility into whether your employees are keeping their operating system and app updated. Every device behaves a little differently, and you likely don't want to be troubleshooting the variety of different problems that arise from a disparate fleet of devices.

Android OS Version

You must make sure the device meets TrackAbout's requirements (above) for minimum OS version. The higher the version number, the better. Plan for at least 3 years of OS updates, and understand that TrackAbout will drop support for older versions of the Android OS at least annually.

Monthly Android OS Security Updates

Google releases monthly operating system security patches. It's important for your security and the security of your company that you choose a phone that will receive these updates. Bargain devices tend to not receive the updates. Some carrier-sold devices do not regularly receive updates. Devices sold directly by Google in their Store will always receive timely updates. Flagship devices like the Samsung Galaxy series sold by network carriers will likely receive updates. Ask when buying or do some research to find out.

CPU + Camera

Scanning QR and barcodes using the smartphone's camera requires a powerful CPU. A bargain phone will likely have a poor camera and a sub-par CPU. Most mid-tier devices made in 2017 and later will probably have acceptable camera and CPU performance, but you should buy one phone and test it, and return it if it doesn't perform well enough. Compare the performance to a high-end Android or iPhone running TrackAbout.

Battery

Most Android devices get 3 to 4 hours of screen on time (SoT) under typical usage scenarios before needing a recharge. Barcode scanning makes heavy use of the camera to take rapid images of the target barcodes. Those images are fed to the CPU for image recognition processing (finding the barcodes). Barcode scanning can therefore drain a battery faster. Opt for a phone with an over-sized battery when possible. A phone with replaceable batteries could be a good choice, or provide workers with car chargers or portable battery recharge packs for use in the field so they can keep going all day. Be aware of Quick Charge technology and buy compliant Quick Charge chargers.

Buy One and Test

What kind of environment are your workers in? Outdoors? Indoors in low-light? Some cameras do not perform well in low-light, they may have auto-focus problems which impacts scanning. It's important that you try out a phone in your environment before purchasing in quantity.

Useful Service Life

Consumer-grade smartphones have a useful service life of about 2 years. After 2 years, one of two things will happen. (1) The battery will age and fail to hold a reasonable charge. Batteries can sometimes be replaced, but it may not be cost-effective. (2) The device will no longer receive security updates. In either case, the device should be replaced.

Rugged-grade Android devices may have a longer service life of 4-5 years. However, they will likely not receive security updates.

TrackAbout's Android Support Policy Explained

What is TrackAbout's reasoning for supporting certain versions of Android?

See Wikipedia's Android Version History for detailed timeline of Android's version history.

Google increments the major version number of Android (e.g. Android 7.0 to Android 8.0) once a year.

Google increments the minor version number of Android (e.g. 7.0 to 7.1) occasionally. and with no set schedule. Google does issue monthly security patches that typically don't change the minor version number. However, not all phone manufacturers or cell phone carriers deliver the Google security updates monthly, if at all.

Google has an unwritten policy that states that its manufacturers should provide Android updates up to 18 months from a device's introduction date. However, manufacturers are not required to not follow this policy.

Different device manufacturers (Samsung, HTC, LG, etc) update their devices at different speeds. Traditionally, manufacturers have been slow to update devices, and have been known to abandon specific devices before 18 months have elapsed. This leads to a large number of simultaneously active versions of Android in the wild.

Android phones and tablets are generally a consumer technology, and the pace of change in the consumer space is rapid. Whereas rugged enterprise devices are typically expected to have a useful service life of 4-5 years, consumer technology generally has a life-span of 2 years.

There are a rugged Android devices available, and the version of Android OS installed on rugged devices tends to lag behind the latest consumer devices.

TrackAbout is sensitive to the needs of its customers and does not wish to unduly prohibit use of the app by paying customers who haven't yet or cannot update their devices to the latest version of Android. On the other hand, supporting so many different versions of the Android operating system adds complexity and maintenance costs to the software development process.

TrackAbout's Android Version Support Policy balances the competing realities by:

• Supporting Android versions that have 10% or greater market share according to Google's monthly statistics.
• Supporting rugged Android devices on a case-by-case basis and for as long as we reasonably can. Rugged device Android versions tend to lag consumer device versions and do not generally receive updates. It has been our experience that Android software development tools change to keep up with the latest versions of the OS, and sometimes we do not have a choice to support older operating systems. This can make it prohibitively expensive to support older versions of Android.
