My wife's Droid Razr Maxx phone is new to her (purchased used). I'm not sure if the problem has always existed on the phone. It seems different from the hardware problems I have read about. It is running the latest OTA Rom (JB 4.1.2) I tested this problem with the phone rooted and unrooted without any change. The phone will not ring or alert on phone calls and text messages regardless of any settings. In a phone call, however, the speaker clearly works, BUT once I turn the speaker on (blue bar shows below the word speaker), I cannot turn it off during that phone call (no blue bar under speaker, but I'm still on speaker). Am I correct in assuming that the phone uses the same speaker for ring and speaker phone? If so, it does not seem like the speaker hardware problems I have read about. It seems like a software problem, but I don't find anyone discussing exactly this issue? Any ideas on diagnosing this problem? Anyone experience a similar problem?
