Dolphin Browser

At present, the Silk browser on the Amazon Fire tablet does not reliably open an APK download link passed to it by a QR code reader: it opens a new tab but then closes it immediately without downloading the file. Silk previously worked fine, but an update over the summer has broken it.

For anyone using Amazon Fire tablets who experiences this, Dolphin is an alternative browser that works well. Dolphin is not available in the Amazon App Store; to install it, open the Silk browser and go to http://dolphin.com/download, then click the button marked "Download Dolphin APK for Android". This will download and install the Dolphin mobile browser.

The next time a QR code is scanned, you will be given the option of opening the URL in Dolphin instead of Silk.

Update: the build of FireOS 5.6 pushed out in December 2017 appears to fix the Silk browser bug
