Yep in my case it helped. After reading other thread about the sealant I looked into the microphone hole of mine and it was completely shut off with the white sealant. No wonder no one could hear me unless I shouted into the mic. After a few minutes of cleaning mine I can speak a normally on calls and people on other end hear me fine.so some of you removed the water blocking white sealant and microphone started working(probably was working before the stuff was removed).. Since this is most likely firmware/software..will the Unified 1/8 1900/2100 Unrooted Secured Tuned Stock Rom help?
Thanks

Like others have said poor quality build control. Individual assembler just soused the sealant to my truesmart not concerned at all if they were assembling a working product. Just get it down the line.
