I bought a droid 4 from a girl whom had it rooted, I myself know nothing about a cell phone being rooted and the whole purpose! I noticed when a call comes on or when I make a call I can hardly hear the person, however speakers work great on videos and music, so I went by Verizon spoke to nice man there he let me know my phone was rooted and fully rooted and may need ROM, when rooting phone some things we lose. Any fix for hearing ppl I speak to on calls very faint low.... and well if not how do I remove this root easy way... I been doing research and wow I am so lost... I have no clue how to do the whole droid4Utility0.3 totally lost.. and scared I am or will do something wrong, all I want is sound in calls... everything else on the phone works great. And then someone mentioned to install motoblur and well then I really got lost, if anyone has the time to help, I know it is asking a lot and yes I am a NOOB.. lmao but ugh all I want is to hear my callers
