I have this exact same problem....cleared the cache on all 4 phone apps but did NOT clear the data as that kinda scares me a bit. Still note fixed AND today the level is even lower than yesterday. So frustrated!!!!
This worked for my phone. I also cleaned the ear piece with a tooth brush and alochol ( which I had done before and it didnt work). I also restarted the phone after. I am so pleased! I almost bought a new phone because of this one reason! Thank you!
Hello, just following up to see if the steps provided were helpful?
Well I solved my issue,what I did I used a slightly wet tooth brush and clean the earpiece while blowing in it and den dried it off whilst blowing also into the earpiece
I cant find this app anywhere.
I had the same exact issues as everyone else in this thread. I had low in-call volume coming from my top speaker. After doing a little research and trying everything in this thread, I found an app/compressed air combo bought back the sound to my in-call volume. What worked for me was an app that I could control the frequency at which the sound is coming out.
I played the sound of the app between 1900 and 2500 Hz and alternating within those values while gently blowing into the top speaker. After I noticed a significant increase in sound, I immediately made a phone call to check if it worked. It did! I would suggest trying that before resetting your phone.
