The antenna seems really weak compared to other androids. It barely hits -119db and switches to 4G-hspa
Hope Apple can fix it, makes my phone unusable at work, keep dropping to Edge. My other androids rarely drop to edge. My new iPhone 5S had dropped to Edge about 20 times today at different locations!!!!
Also I see lower signal when I grab from bottom covering bottom antennas. I though this phone had dual antennas. If I grab the top camera end and leave the bottom unblocked my reception increase -13 digits or one DOT.
