I am currently using a droid 3 (rooted).
I have been fairly happy with this model, except two years in and I still haven't gotten used to swype and the manual keyboard has issues with my fat fingers.
Recent issues that have developed: I cracked the corner of the screen and that has caused a few issues. Like the touch screen precision is off a little. The front camera (self facing) doesn't work real well. It causes the camera. App fails to initialize error when selected. Then I have to reboot to get the other camera to work again.
Of. Course most of these issues are due to dropping the phone, which let's face it, isn't the phone's fault.
Recently, the phone runs awfully slow no matter how many apps I remove. Even did a factory reset and it's still slow. Perhaps the os has bloated some more from verizon. Of course it could be that crack too. I think I got a little water in there or something ...
I'm iinterested in the d4. So, I'm looking at reviews and complaints to see if its worth a look at verizon.
