Third party reader apps all seem to work well on the T63. I am beginning to encounter glitches in the Boyue firmware. The Boyue file manager will sometimes crash. That's only a problem because that file manager also manages what appears when you touch the Books icon on the home page. I can access my books by starting up any of my reader apps and choosing the book from within the app. The glitches seem to prevent any book from showing up in the Recently Read section of the home page.

As far as file managers go, Root Explorer has no issues at all. That's why I suspect it's the Boyue apps themselves that are glitchy.

I read somewhere that some microSD cards can give a Boyue device a case of "indigestion". I only have one spare sd card now, so I can't test this hypothesis and see if another card helps.

With Moon Reader, I have to push the page turn button twice to get the first page turn to happen. After that, each push turns the page. That's the only glitch I've seen in that app thus far. KOReader seems pretty smooth. I haven't tried AlReader yet.

Edit: I've dome some customization. I replaced the Books icon with Calibre Companion. I can use that as my library. I've replaced the Filemanager icon with Root Explorer. Filemanager is pretty useless anyway. The glitches are minor thus far, and do not affect the functioning of the device in general. Calibre Companion works well as my library app. I can select any book there and get a pop-up window listing all my reader apps, and then choose the one I want and/or select one app as my default reader.
