How to use the bootloader:
• The list of firmwares should automatically be filled (make sure you have a network connection!)
• Select a firmware (make sure you select the right one depending on which Crazyflie you want to update (CF1 or CF2))
• Flash firmware (For Crazyflie 1, click on "Flash firmware" and switch on the Crazyflie during the next 10 seconds. For Crazyflie 2, press the ON/OFF switch of the Crazyflie longer than 1.5 second until one blue LED blinks. Then release the button and both blue LEDs should blink. Then click on "Flash firmware")
• After a successful flash the Crazyflie will automatically restart in firmware mode and is ready to use.
It's nearly impossible to brick the Crazyflie. In case of any problems during flashing, you can always try again or use the PC client to re-flash.
Permissions:
* Photo/Media/Files: This is required to save the firmware files on the device. * Bluetooth connection information: This is required for connecting to Crazyflie 2.x over Bluetooth. * Location: This is required for Bluetooth LE scanning since Android 6.0.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be se.bitcraze.crazyfliecontrol2 is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.7.5 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Crazyflie Client first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Crazyflie Client, and a listing is removed when the evidence for it stops holding up.
