Logos for Android has always had a problem with displaying some Greek and Hebrew characters in the Information pop-up window.
I was under the impression (http://community.logos.com/forums/t/53055.aspx) that this font problem would be resolved with Android 4.2. I now have Android 4.2.2 on my Samsung Galaxy Note 8 and there is no difference in the display of Greek characters. With some combinations of diacritical marks, there is no character displayed at all. I have been waiting a long time for Android 4.2.2. to arrive on my Samsung tablet and phone, so I am very disappointed that this did not resolve the font problem.
