My thoughts on the 4.3 build test so far: It's breathed new life into my phone! Seems quick and responsive. A few issues I've found:
1. The font in the default HTC Mail app is bold even for read emails - too hard to tell the difference between read and unread at a quick glance.
2. A few quirks in the HTC messaging app. Pictures show up NOT as thumbnails in the message thread, so you have to click to open it to see the whole picture.
3. When sending a text, it takes too long for the text to leave the typing space.
4. The font on the time & weather widget for the date is in all caps - not sure if it's a bug or not but it drives me crazy! (ie, WED, FEB 12 instead of Wed, Feb 12)
5. When you press the home button from any app, it doesn't return to the default home screen - goes back to whichever one you were on before. Not sure if this is a bug, but I don't like the way it works.
6. The ringtones/alerts are different. Not really a bug, but I was disappointed I couldn't find my old ones.
7. When the volume is turned all the way down and it vibrates - it's not a pure "silent mode" - the media volume is still up. I took a screen shot when the ringer was off, and it still made the shutter sound...quite loudly.
That might be all for the moment. What are other people's thoughts so far??
