Amazon bug in Kindle Fire

Posted by universalis on 11 February 2015

On 10 February 2014 a bug was reported to us on the Kindle Fire, which caused the Universalis app to stop working. The bug only affected certain models of the Kindle Fire, and possibly only certain users of those models. Amazon are incapable of providing technical support.

Everybody’s Universalis apps started working again, eventually. The full details are below, copied from the original article.

On 10 February 2015 the same thing has happened. The symptoms are the same, and again the problem seems to cure itself spontaneously in the end. Because it is an intermittent problem, it is not possible to tell what is causing it, or what actions will make it go away, or whether it is just necessary to wait a day or two for the problem to go away by itself.

The Universalis app for Android exists in only one version, for all Android devices, so there must be something special about the Kindle Fire.


The Universalis application works perfectly in every respect except the following:

  • All the text pages (the Hours, the Order of Mass, Readings at Mass) are completely blank.
  • In the “Font size” setting screen, the sample text is blank.


For some people, this happens all the time. Others have found that it sometimes happens and sometimes doesn’t: they try, and they see blank page; they try a little later, and they see text.

One user reports that deleting and re-installing the Universalis application cures the problem (for a short while). Others report that it doesn’t.

Some people report that shutting down their device and starting it up again cures the problem (for a short while). Others report that is doesn’t.

One user reports: “I switched my wifi off and on again and I got to Vespers. Setting it up for Compline failed. Switching wifi off and then on again brought up Compline.” We would be very interested to know if other people have the same experience. But that user then wrote back and said that the next day everything was working perfectly!
