I have noticed a strange problem with my Epic 4G after the recent update. When I get a voicemail and use the voicemail app to access it, it comes out of the back speaker like it's on speakerphone, even with it set for the ear speaker. Hitting the speaker button only makes the back speaker louder, it doesn't change to the ear speaker. The only way I can get it to function correctly is to call my number and enter my password to access my voicemail. Then when I go back to the voicemail app, it behaves correctly and I can switch from ear to back speakers - until I get another incoming voicemail.
Rebooting and/or pulling the battery don't help. Anyone else notice this?
Well at least I'm not alone in this. Another problem that I am pretty sure is related to this is the failure of the speech to text capabilities, because they both occur simultaneously - at least on my phone they do. This applies to the Google search, text messaging and probably any other function that uses the little microphone button for speech to text. Rebooting does temporarily correct this, but it is a recurring issue and it really sucks having to repeatedly reboot the phone. More evidence that this Epic 4G is a buggy piece of junk.
I have found that this problem doesn't only occur when voicemail is left, but any time a call is received. it doesn't seem to affect the ear speaker in the call, but if I go to voicemail, or any speech to text app after a call is received, it reverts to the problems mentioned above and a reboot is necessary to correct it. When another call is received it's the same problem again, whether I answer it, or not, or whether they leave voicemail, or not. I am constantly rebooting my phone now. I agree completely that it is the EL30 update, because before that I never experienced this problem. I hope like **** Sprint fixes this soon.
I have found that this problem is associated with the ringtone, which apparently became corrupted with the EL30 update. I don't know if it is just the particular ringtone that I was using when the update occured, or if all the pre-installed ringtones are effected, but I downloaded a custom ringtone and the problem stopped immediately upon using it.
It was the incoming call ringtone and the only one I had to change. I downloaded a new ringtone from www.zedge.net and it hasn't recurred since. I don't know if just changing the one you were using when the update occured to another one that's already on the phone will fix it, but you could just try that first.
