The Droid DNA has been a miniature hot bed seeing as that its release date is not for a couple of days. We have an unlocked bootloader, we have root, we have custom recoveries, we have an unsecure kernel, and now we have a working Flashlight app. I know not the hugest of developments, but it is one thing that I can not live without. This is just an apk. It is not a flashable.zip.
To install you will download the file at the source link. Then use "ADB install (filename)"
Hopefully the unlocked bootloader will still be a thing on Wednesday, and hopefully their will still be plenty of intrest on the part of the development community to keep the mods coming on this sweet device!
