The Bionic does not seem to like apps on the external SD card. I had all sorts of app issues until I put the apps on internal storage.
I personally have had zero spontaneous reboots and very few data drops. I live in a 3G area and have 4G disabled.
In most ways the Bionic is the best of the half dozen different smartphones I have had. I am however, in a bit of a quandary as to whether or not to keep the Bionic. I am getting close to my 30 day period and need to decide if I want a RAZR or Google Nexus pretty quick. The Bionic is fine for the way it works now, but the problem I see is the state (or lack thereof) of continued custom ROM development. There are comments all over about how Bionic development is dead. Most of the ROM OP's have not posted in their Bionic ROM threads for a long time. I have a dread of deciding to keep the Bionic, then finding that the next great update to fix all of the issues will see no development to support the update, and we're stuck on rooted stock.
So I suppose the question for me hinges on which of the Bionic, RAZR, or GNex will see the best, most sustainable development to last until Google's purchase of Motorola finally yields something like the Google Droid Nexus that won't have all the locked bootloader and other anti root crap we have to fight our way through. The Bionic is good enough for that now, but with ******ed development how long will that last?
