How to Install Android 15 Vanilla Ice Cream [2 Methods]

In this guide, we will show you two different methods through which you can install the latest Android 15 build onto your device. It’s that time of the year when we are about to be treated with a new set from the Silicon Valley giant. This time around, it’s the Vanilla Ice Cream that has been served to us, although a tad bit later than the previous iterations [Android 14’s Preview was released on February 8, 2023].

With that said, there are still plenty of reasons to get your hands on this iteration, among which, the Private Space has been the talk of the town. Apart from that, there is a slew of other noteworthy features as well, including Notification Cooldown, Lock Screen widgets, Battery Health Percentage, App Archive, Bluetooth Quick Settings menu, the ability to Save App Pair, and a new “Security State” API which will further enhance the security of the OS.

So without any further ado, let’s dive deep into the ingredients [feature list] for the Vanilla Ice Cream, after which we will show you the first-hand impressions [aka the installation steps] to create this ice cream for yourself. Follow along. 

Android 15 Vanilla Ice Cream Features

install android 15

Here are all the noteworthy and intriguing features that you would come across on the fifteenth iteration of the OS build. [NOTE: Since we are currently in the developer preview phase, there are a few features that are yet to be confirmed/officially announced, but they have been found in the leaks so they will make their presence felt sooner than later (maybe further down the lines of Beta or directly to the stable builds, or even via a Feature Drop. Anyways, till they get the stamp of authority from Google, they will have to wear the badge of uncertainty].

Partial Screen Sharing

This feature will allow you to share your screen just inside an app window instead of the entire device [NOTE: it first made its way to Pixel with Android 14 QPR 2 and is widely available across non-Pixel devices with Android 15].

Notification Cooldown

It will gradually lower down the notification volume when you keep on getting the alerts from the same app.

*Lock Screen Widgets

We first saw a glimpse of Lock Screen widgets all the way back in Android 4.2 but for some reason, Google decided to remove it from Android 5. And now that Apple has added it, how could the Silicon Valley giant be left far behind? As of now, all speculations point towards the ability to add widgets in the lock screen either on the Communal Space or via the At a Glance widget.

*Battery Health Percentage

Another feature taken from the iPhone’s book, it will let you know how far your battery has degraded with time. Or to put it the other way around, the remaining battery health in percentage.

*App Archive

Sorry, but we cannot stop mentioning iPhones in this list. Akin to iOS’s Offload Apps feature that allows you to uninstall the app but keep its user data intact. So when you reinstall that app, you could start from that left-off position, instead of starting from scratch. We are now witnessing a similar in Android 15.

Titled App Archive, it will remove most of the app data from your device and will only hold down to the most crucial ones. You will still get its icon in the app drawer though, clicking on it will take you to the Play Store where you can unarchive it if required. Apart from that, the Archive and Restore options will also be present on the App Info page of each individual app.

*Bluetooth Menu

Till Android 14, when you tap on the Bluetooth Quick Setting tile, then it will simply enable it. However, if you frequently interact with numerous Bluetoo devices, then you’ll have to long press on that tile to open the Bluetooth menu and then choose the desired device.

This is about to change in Android 15 wherein if you tap on the Bluetooth Quick Setting tile, then it will bring up a list of Bluetooth devices right then and there, from where you can directly choose the device that you wish to connect [similar to how the WiFi Quick Setting tile].

*Private Space

Similar to Samsung’s Secure Folder, Private Space will create a locked secure environment wherein you can hide your apps and data. This space could only be unlocked via the password that you had initially set up. Furthermore, you can access it from the Settings > Security & privacy > Private Space menu.

*Save App Pair

The App Pair feature which allows you to couple two apps together in the split screen mode was present in the earlier OS builds as well. However, up until now, you had to manually create the pairs each time you wished to use them in the multi-screen window. With Android 15, this process has been streamlined as it allows you to save those pairs on the home screen. You could then just tap on that icon and it will launch the app pair in one go.

Privacy Sandbox

This feature will limit the sharing of user data with third parties with the major objective being a privacy-enhancing advertising solution where user information is protected.

How to Install Android 15 Vanilla Ice Cream

The below process will wipe off all the data from your device, so take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

STEP 1: Install Android SDK

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used in this guide.

install adb platform tools windows

STEP 2: Enable USB Debugging and OEM Unlocking

Next up, you will have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader unlocking process.

install android 15

So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.

STEP 3: Unlock Bootloader

Next up, you will also have to unlock the device’s bootloader. If you had performed the update via Flash Tool or Fastboot, then the bootloader would already be unlocked. However, if you had performed the upgrade via ADB sideload, then would you need to carry out this task? Do keep in mind that doing so will wipe off all the data from your device and could nullify its warranty as well. So if that’s all well and good, then please refer to our detailed guide on How to Unlock the Bootloader on any Android Device.

NOTE: We are unlocking the bootloader because as of now we won’t be getting the OTA updates for Android 15 till the initial few Developer Preview builds. Once it reaches the beta stage, you can enroll as a beta tester and get the latest Android 15 as an OTA update without the need to unlock the bootloader. [With that said, if you are planning to install it via Android Flash Tool or Fastboot Script, then unlocking the bootloader is a must, irrespective of the fact whether it’s Developer Preview, Beta, or Stable].

install android 15

Moreover, at the time of writing, the Developer Preview OTA updates are not working, so you have no other option but to opt for AFT or Fastboot Script.

  2. Once downloaded, extract it inside the platform-tools folder.
