During Mobile World Congress in 2019, Sony unveiled the Xperia 10 and 10 Plus, two mid-range smartphones with tall 21:9 displays. The phones launched with Android 9 Pie on board, but Sony promised an update to Android 10 "early 2020 onwards". Sony quickly added both devices to the company's Open Devices Program, and the device duo got official TWRP and LineageOS 17.1 support earlier this year. Now, it appears that Sony is officially rolling out the Android 10 update for the Xperia 10 and 10 Plus.

According to users on Russian forum 4PDA, Sony is pushing the stable Android 10 update to Xperia 10 and 10 Plus users. The software version is 53.1.A.2.2 (bumped from 53.0.A.14.47) with the March 2020 Android Security Patch Level and is available for both the single SIM (10: I3113 / 10 Plus: I3213) and dual SIM (10: I4113 / 10 Plus: I4213) models in Russia and other European countries.

Sony hasn't published a proper changelog for this update as of yet, but the new build should introduce all the new features to the Xperia 10 series that Google rolled out with Android 10, including a system-wide dark mode, gesture navigation, smart replies, and more. The update is being rolled out in a staggered fashion in order to ensure a smooth rollout, but the full firmware package can also downloaded using the XperiFirm tool by XDA Senior Member IgorEisberg. Power users can then opt for either Flashtool (GUI) or Newflasher (CUI) to perform a manual flashing, though we would still advise caution.

Both Xperia 10 devices feature 64GB of internal storage, a side-mounted fingerprint sensor, headphone jack, SD card slot, USB-C, and NFC. The primary difference between the two is in terms of processing power. While the Xperia 10 Plus is equipped with the Qualcomm Snapdragon 636 platform, the other one is powered by a slightly less-powerful Snapdragon 630 SoC. The regular model also features a depth sensor, which is substituted by an 8MP telephoto shooter on the Plus variant.
