Hello I have been having an issue for quite some time now and was hoping someone could help me. I have a fully flashed evo 3d and from time to time when someone calls me instead of ringing they get sent straight to voicemail like if my phone was off any ideas why this happens? my phone does switch from 3g to 1x from time to time. ive tried using a different prl like a sprint instead of cricket and looks like the prob seems to be solved but the internet on it is super slow please help!
