It has been a little over 3 months that I purchased this phone and ... moreI am also affected by this last update. Outgoing call quality of my Vivo 5r became unusable after installing it. I may have found a workaround /solution that works.
This seems to have worked for me but PLEASE use this information at your own risk. Fiddling around in your phones engineering settings mode can be a recipe for disaster and can break your phone permanently! So, if you're not sure what you're doing by following these instructions, your best bet is to contact Blu for warranty service and have them resolve the issue for you. In any case, if you're feeling lucky and want to give it a shot, here's what I did:
1) Go to the Setting -> Cellular network setting and disable "Enhanced 4G LTE Mode"
2) Go to the Google Play Store and download the "MTK Engineering Mode" app. (https://play.google.com/store/apps/details?id=com.themonsterit.EngineerStarter). This app lets you tweak certain hardware level settings on your device, including the microphone sensitivity settings that were broken by the wireless update that Blu pushed out.
3) Launch the MTK Engineering Mode app and follow these instructions: Steps:
A. Select "MTK Settings"
B. Swipe left to get to the "Hardware Testing" tab
C. Select "Audio"
D. Select "Normal Mode"
E. Under the pull down menu for "Type" select "Mic"
F. For "Level 0" set the "Value" field to "255", which is the maximum
G. Press the "Set" button. You'll get a confirmation that the setting has been changed. Just dismiss it by pressing "OK".

No one can hear me not to mention the bluetooth is awful. Blu says the same thing to me, haven't heard of this problem. I'm sending the phone back. I was wondering if updating it to Nougat would fix it. I wonder what other blu phones have this problem. --Very disappointed. Loved this phone.
hasanarif997, 02 Jul 2017Wireless Update Jun 2017: It has been a little over 3 months that I purchased this phone and ... moreSame issue. Did the wireless update and no one could hear me. Thought it was from dropping it too many times. Got a new one. Talked to several people on the new phone and they could hear me! Did the update, no one can hear me again. Have called Blu multiple times and they say they have not heard this was a problem?! If you have the blu vivo 5r refresh and did the wireless update and hard reset and still no one can hear you, PLEASE call them and make sure they document it.

OML I NEED YOUR HELP RIGHT NOW.
I have my guest mode on and I can't disable it! I searched on Google but I found nothing! I can't find anything in my settings to!
hasanarif997, 02 Jul 2017Wireless Update Jun 2017: It has been a little over 3 months that I purchased this phone and ... moreI have the exact same problem. After installing that update, I haven't been able to have proper phone calls. My friends told me that it sounded like I was somewhere underground with loud noises surrounding me, and they couldn't make out what I was saying, yet I could hear them fine.
Wireless Update Jun 2017:
It has been a little over 3 months that I purchased this phone and I have started facing issues with the call quality. I have installed latest wireless update: BLU_V0090UU_V24_GENERIC_6.0_07-06-2017. The people on the other end of the line complain that my voice goes extremely low and becomes impossible to make out what I am speaking. I went for factory data reset. But the problem is not solved yet.
