Support for MobileXPRT 3 will likely end soon

In a past blog post, we discussed our plan to move several older versions of XPRT benchmarks to an XPRT archive page. Some of those legacy XPRTs still function correctly, and testers occasionally use them, but a few no longer work on the latest versions of the operating systems or browsers that we designed them to test. With the archive page, we can prevent potential confusion for new users who visit current XPRT pages, but still provide longtime users with continued access to old tests.

You can find more information about the XPRTs that we’ll be moving to the archive page here, but today, we want to let MobileXPRT users know that there’s a high likelihood that MobileXPRT 3 will be joining the list of archived XPRTs in the very near future. The Google Play Store has notified us that, due to evolving requirements for apps in newer versions of Android, we must update our MobileXPRT 3 app package to target an Android API level within one year of the latest Android release. If we don’t update the app to meet that requirement by November 1, users will no longer be able to access MobileXPRT 3 through the Google Play Store.

Though a small number of labs and reviewers still use MobileXPRT 3 to test phones and tablets around the world, we don’t feel current usage is high enough for us to justify committing resources to an update at this point. We had hoped that even if MobileXPRT 3 became inaccessible via the Google Play Store, it would still be possible to sideload the app for testing on newer Android devices. After experimenting with installation options in the lab, however, we think it’s likely that settings on devices running Android 11 and up will prevent both Google Play and sideload installations after November 1. The situation may change, but right now, we don’t expect any method to work after that date. If you try, you’ll likely encounter a message during the installation process that says, “This app was built for an older version of Android and may not work properly. Try checking for updates, or contact the developer.” If you attempt to continue the installation process after that message appears, the app will crash.

Both Android and Chrome developers know that the respective stores sometimes extend these types of deadlines. We hope that will be the case here, but we have no information that would lead us to anticipate an extension. If there is no extension, we will still make MobileXPRT 3 available for testing on older Android devices, but we will then have to move it to the XPRT archive page.

We’re grateful for everyone who has used MobileXPRT 3 in the past, and we apologize for any convenience this change may cause. If you have any questions or concerns about MobileXPRT 3 access, please let us know

Making progress with WebXPRT 4 in iOS 17

In recent blog posts, we discussed an issue that we encountered when attempting to run WebXPRT 4 on iOS 17 devices. If you missed those posts, you can find more details about the nature of the problem here. In short, the issue is that the Encrypt Notes and OCR scan subtest in WebXPRT 4 gets stuck when the Tesseract.js Optical Character Recognition (OCR) engine attempts to scan a shopping receipt. We’ve verified that the issue occurs on devices running iOS 17, iPadOS 17, and macOS Sonoma with Safari 17.

After a good bit of troubleshooting and research to try and identify the cause of the problem, we decided to build an updated version of WebXPRT 4 that uses a newer version of Tesseract for the OCR task. Aside from updating Tesseract in the new build, we aimed to change as little as possible. To try and maximize continuity, we’re still using the original input image for the receipt scanning task, and we decided to stick with using the WASM library instead of a WASM-SIMD library. Aside from a new version of tesseract.js, WebXPRT 4 version number updates, and updated documentation where necessary, all other aspects of WebXPRT 4 will remain the same.

We’re currently testing a candidate build of this new version on a wide array of devices. The results so far seem promising, but we want to complete our due diligence and make sure this is the best approach to solving the problem. We know that OEM labs and tech reviewers put a lot of time and effort into compiling databases of results, so we hope to provide a solution that minimizes results disruption and inconvenience for WebXPRT 4 users. Ideally, folks would be able to integrate scores from the new build without any questions or confusion about comparability.

We don’t yet have an exact release date for a new WebXPRT 4 build, but we can say that we’re shooting for the end of October. We appreciate everyone’s patience as we work towards the best possible solution. If you have any questions or concerns about an updated version of WebXPRT 4, please let us know.
