Try swapping it out for a replacement, sounds like a lemon to me.
heres my take on the droid charge..
i had a fascinate and never could get the calls out or in to stabilize.. always missed portions of a word maybe even a whole sentence. the fassy took great pics and music for calls etc but the signal strength sucked bad..
i called tech about it twice,, once before it took a swim in a sting ray tank..and once after the fassy showed it was water resistant..
my secon call i was offered a droidx2 , my reply was that i did not want a snapdragon processor.. and ask if there was something newer and not something that would be ouitta date as soon as i got it.. so they offered me a droid charge.. i jumped on that.. i've had it 3 days so far and havent noticed any problems.. it acts like any other smart/dumb phone... last night it turned its self off.. i woke up checked for battery life and noticed it was off.. i did about 5 reboots from time to time as i loaded apps that i wanted and it leveled off no more shutting down..it appears to be stable and as far as 4g goes ..welp it wont work but i live in a fringe area...
the charge will make/recieve calls much better and no garble in words..(seems some sim cards are defective, by verizons mouth and they will change them no hassles)
Right Now Verizon is chomping at its bits trying to gain new customers and not lose existing customers so they will work with anyone so far.. also when i went from a 3g sammy to a 4g lte charge there was no extra charges for the step up... tech told me that there was a lot of repports in my area about the sammies and was more than happy to step me up.. also store manager had to go to his whatever and get a new sim card because they didnt send one with my charge..
so yes i am sure i'll see some creaks and cracks and might even say the charge is garbage later but for now its the smartest thing i've done with Verizon...
a point to everyone... the charge has a built in antenna,,,, read it in the specs.....
the fassy has no built in antenna... thus a pisspoor signal..
even after its swim,, the fassy was as good or maybe a tad better than before the swim but still a piss poor signal....
i think me and this charge will get along just fine..
oh there is one defect though... its a pre-installed game named "Lets Golf" it cost 5 bucks if ya want it.. so dont let yer fingers do the walking... it can not be removed... i have tried,,, i hate when someone or thing tries to push me anywhere or into anything... that game has got to go...
but i love my charge.. perhaps you missed a step rooting etc...
