Sony’s SmartWatch has custom firmware in its future, as company opens it up to developers

smartwatch-de-sonyCheck out our review of the Sony SmartWatch 2 watch.

Launched last year, Sony’s SmartWatch, one of the least hideous examples of the new tech craze, has struggled to find an audience, however that may change in the near future. The company has announced it has opened up the device to developers, and is actively encouraging them to write custom firmware for it.

Developers could write applications for the SmartWatch already, but by opening up the OS, we could see some radical changes to the wrist worn gadget. In case the SmartWatch has passed you by, here’s a reminder of its specs. The little OLED screen measures 1.3-inches and has a 128 x 128 pixel resolution, which may sound basic, but it is color, unlike the E Ink Sonostar we saw recently. It’s powered by an ARM Cortex M3 processor made by STMicroelectronics, and has Bluetooth connectivity.

The SmartWatch runs a modified version of Android, which makes the thought of custom firmware even more interesting, and once connected to your phone, reads SMS, email, tweets and Facebook notifications, plus it can answer or reject calls, and control the music player. At 26 grams and 8mm thick, it’s suitably slim and light.

Of course, anyone keen to start cooking up some new software for the SmartWatch will understand it’ll void the warranty on the device, and once the firmware has been altered, all of the apps already available for it through Google Play – nearly 200 at last count – will no longer be compatible. However, should one of the established groups which creates custom ROMs for Android phones feel like having a go at the watch, we’re sure this won’t affect it it in the long run.

We’re still expecting a wave of smartwatches from most major manufacturers, including Samsung, Google, and Microsoft. Apple’s example, which is one of the most enduring rumors, was last said to be arriving late next year though, and as you can buy Sony’s SmartWatch, and the Pebble, right now; this is exactly the type of move which could see them become more popular before more competition arrives.

Google’s new Android XR tools let developers test apps without needing to buy expensive smart glasses
Google has also added new Android CLI tools to help AI coding agents test apps and catch performance issues.

At the 2026 Android Dev Summit, Google has announced some interesting features coming to both Android XR and Android CLI. Developers can now build and test apps for smart glasses without owning the hardware, while Android's command-line tools are getting upgrades that help AI coding agents test applications and identify performance problems. Both announcements could eventually mean better apps for both Android and extended reality hardware users.

Some Galaxy Watches may be too old for Samsung’s biggest sleep apnea upgrade
Samsung is adding three levels of breathing disturbance data, but the full feature won’t reach every watch that supports basic apnea detection
Body Part, Hand, Person

Samsung is making its Galaxy Watch sleep apnea tracking more useful than a simple warning. The upgraded system estimates how often breathing disturbances occur each hour, then sorts the result into three frequency levels.

There’s a catch for anyone holding onto an older model. Detailed results require Wear OS 7.0 or later, while watches stuck on older software will keep simpler alerts.

Not everyone can afford to hire a personal trainer. And let’s be honest, learning exercises from YouTube or the gym regulars isn’t exactly foolproof. We need a solution that is both affordable and accurate.

A research group at the Indian Institute of Technology Gandhinagar (IITGN), led by Dr Biswajit Saha, has a solution. He created a bendy wearable sensor that works in the gym and for sports like tennis and swimming.
