No, that's not the solution. The OP would have the same issues.
The problem really isn't with the Droid. What the OP is describing as hardware issues are more likely apps causing issues with his OS. OP, do you have any virus protection or task killers? If so I recommend getting rid of them. Also simple things like turing your Droid off and on will also help.
In almost every case I've seen of multiple returns like this it has to do with the person who owns the Droid not really understanding how the OS works. OP I'm not saying that in any attempt to put you down, far from it, I'm just sharing my experience of what I've seen from others who have had issues like this.
One or two Droids could be bad. But 4 or 5? I don't think so.
No offense taken at all. I appreciate your advice. But this device I'm on right now, I just received it Wednesday afternoon. I decided to take my friends advice and keep it completely stock for a week, and than install one app at a time, and play with the device for a while before I install another app. Well, that plan got derailed last night when the device just started really acting up. After a little over a day of having this device, it started acting up, which was yesterday around 4pm. And remind you, I haven't installed any apps at all, only thing I did was sync and pair my Jawbone, that is all. After about 3 hrs of the device being off, I turned it on at about 7pm and it was still acting up. So I call VZW, they tell me to master reset. Only issues I had after the master reset was the app menu taking like 3 seconds to open, and after exiting an app by tapping my home button, it would take like 5 seconds for my home screen to fully appear. Let me remind you, I have dozens of friends & co-workers that have Droids and other Android devices, when I play with their devices, their devices perform flawlessly. And I have one buddy that has over 200 apps on his device, problem free and very fast still.
