Google Duo v36 drops Jelly Bean and adds some finishing touches for tablets and smart displays [APK Teardown]

An update of the Duo application is opening, but this seems to be a small service update, at least for now. There is no specific signal that this version will rerun the screen sharing function after it has been thrown in bad condition with v34, but it is possible that the implementation has been fixed and the feature is activated later. Instead, this update marks the end of Jelly Bean support. A disassembly also shows that the official support for tablets is almost here.

Removing Jelly Bean support

We've been seeing a lot in recent months, Google applications are shaving the bottom end of their support list and crashing into something a little new Duo is the last to join the trend, as it leaves Android Jelly Bean (4.1 – 4.3) and sets KitKat (4.4) as the oldest officially supported version.

It is important to keep in mind that this does not mean that the Duo application stops working in Jelly Bean, only that it will no longer receive updates from the application. Users of Android 4.3 and earlier versions will simply stop receiving new versions of the APK, but v34.5 is probably still available in the Play Store and the Duo service will continue to work. However, it is logical to think that the application will finally adopt new protocols and codecs for audio and video that are no longer compatible, and that will finally put an end to the use of Duo in Jelly Bean.

As of May 2018 (Google hasn & # 39; published numbers for June), the three versions of Jelly Bean combine to represent 4.3% of the Android ecosystem. With KitKat as the new base version, Duo still officially supports 95% of the devices.


Disclaimer: Disassemblies are based on evidence found within the apk (Android application package) and are necessarily speculative and are generally based on incomplete information. It is possible that the assumptions made here are erroneous or inaccurate. Even when the predictions are correct, there is always the possibility that the products change or cancel. Like the rumors, nothing is certain until it has been officially announced and published.

The features described below are probably not yet live, or can only be live for a small percentage of users. Unless stated otherwise, do not expect to see these features if you install the apk.

Preparations for tablets and smart screens

We have known for a long time that Duo would be compatible with multiple devices. In fact, since the support of the Google account was added and some errors were resolved, we were able to log in to a phone and a tablet at the same time with the same account and use them perfectly. However, you had to download the Duo application, since Play Store still does not allow direct installation on tablets.

The latest version comes with new and updated text that suggests the computer is almost ready to reveal tablet support. The great addition is the promotional text that leaves no doubt that users can make and receive calls on tablets.

There is also a slightly updated message in the Google login dialog used to explain that you can use your account to be more accessible in Duo. The latest version adds some words to say that you can log in to "other devices" with the same account. It is a small difference, but it marks a change in the language where Duo is more clearly described as a multi-device application.

Left: v34.5. Right: v36.

This is interesting news for tablet owners, even if it's just an omen that they will not have to lose control with Duo in the near future. Of course, this change is probably motivated by the upcoming launch of smart screens, which are probably still about three months away with the release of the first Lenovo model to be shipped in September.


The APK is signed by Google and updates your existing application. The cryptographic signature guarantees that the file is safe to install and was not tampered with in any way. Instead of waiting for Google to download this download to your devices, which can take days, download and install it like any other APK.
