Very low in call earpiece volume after 4.4.2 update
06-19-2015 01:31 PM
- Hey Guys -
Black 16GB Nexus 5 here. My in call volume using the earpiece is very very low since the 4.4.2 update. I have the volume maxed out and have already cleared cache, and even data reset once. Did not help at all.
The only way to use the phone making a call is to use a headset or be indoors in a very quiet room. Even then it's hard to hear the caller using the earpiece. I always have to use a headset for making calls.
I remember the in call volume being louder before the 4.4.2 update. After the update, however, the microphone functionality is improved and people can hear me better now (compared to 4.4.0 stock). However, it's hard for me to hear them.
I just wanted to see if someone else faced this problem or whether this is a manufacturing defect in my phone.

So i use my phone a lot for voice calls and here's what I've found:
1) Prior to the android update (in stock 4.4.0) the earpiece in-call volume was ok. However the microphone was bad. Meaning other people always complained that i sound very far off and they couldn't hear me clearly. But I could still make calls without using a headset.
2) After 4.4.2 update, the microphone issue seems to be resolved. People tell me that they can hear me better. However the earpiece in-call volume is much lower than before. I can only hear people if I am in a very quiet room and even then I have to strain.
The only way to use the phone for calls is to use a headset (both wired and bluetooth work). The other day I was using my old Samsung Galaxy S3 for a phone call. The difference in clarity for phone calls is night and day. I had to actually lower the volume of the S3 because it was so loud and clear.
At this point, I am not sure whether it's my Nexus phone and a hardware defect. Could it be something that google did in the 4.4.2 update (meaning fixed the microphone, but lowered the in ear volume).
I just wanted to put it in this forum to see what other people face this issue. I've tried everything: clearing cache, factory reset, installing 4.4.2 again. But nothing has worked. Furthermore using a headset at max volume sometimes distorts the audio.
Other than this the phone is perfect. The battery life is amazing and it's super fast. The funny thing is that with the 4.4.2 update the phone speaker is better and louder. However the earpiece for making calls is just plain lousy. I can't take calls unless I am carrying a headset with me.
It's a great phone, but I am in a fix if I have to make a voice call and am not carrying a headset.

- Mine is a day 1 (maybe even first hour of sale) black 32gb model. The speakerphone / audio speaker functions did noticeably improve after the 4.4.2 update. Maybe a month after that update, I unlocked the bootloader, which (as I understand) would've been similar to any cache clear or factory reset.03-16-2014 11:41 PM

What I wanted to know was the volume of the earpiece at the top. If one takes calls while holding the phone to ear, the volume coming from that speaker at the top. That seems to be much lower in my phone. It's come to a point where I have to always use a headset to hear the other person.
I was wondering whether that's a hardware defect or it's something that google did when they fixed the microphone in 4.4.2.

- The annoying thing is that for some calls in canvas gold A300 the earpiece volume works well and is very audible. During some other calls , say when i am calling my father and mother who use non android or low end phones, the voice clarity is good and very audible. I found this confusing. Even after giving to the service center i face the same problem. Planning to highlight this issue again. But MMX service centres need our phone to be kept with them for 2 weeks instead of ordering ear piece and calling the customer when the new earpiece arrives. Can't understand why for many issues they are holding the mobile in their hands.04-30-2015 10:06 PM
- Try engineering mode for android :
This will fix the low earpiece volume issue
Engineer Mode Tweaked Audio Level Settings for ThL W8
To enter Engineer Mode dial *#*#3646633#*#*
You can also create a shortcut to engineer mode using your launcher. In LauncherPro, for example, you can long press on an empty space on the home screen and choose shortcut, activities, engineer mode, com.mediatek.engineermode.EngineerMode
Once in engineer mode, slide right two times to Hardware Testing, then choose Audio.
These are the audio levels I'm using for the ThL W8 (4g rom model). Your levels may vary or or your preferences may vary.
-Level 0 through Level 6 are listed in sequence.
-Media setting is for playback of movies/audio/etc in most cases.
-Sph in most cases is the handset (earpiece not earbuds) speaker output in phone calls
-I believe sip refers to VoIP phone call volumes.
-sph2, sid, and matv, not sure what they refer to.
-FMR, is FM radio.
-Ring is ringtone volume.
-Can't set the FMR any lower than 16 and 16 is kinda loud for the lowest volume it will go while earbuds are plugged in. Anyone have a fix for this?
-I'm not sure why there is a 'max vol' setting on most of these as setting a specific volume level greater than the max makes it louder than the 'max vol' setting. Maybe the specific level settings are like a percentage of the 'max vol' setting (like 255/255 is 100%, 64/255 is 25%, 255 being the highest number a single byte (8 bits) can hold in binary notation).
-If the max isn't marked as (unchangeable) then you can change it to something different (higher, lower).
-Max vol setting applies for all levels of a specific audio 'type' and not to individual 'levels.'
-Setting loudspeaker, media to 255 caused slight distortion in my testing, YMMV. 248 seemed just right for loudness with no distortion.
-Other guides mentioned a reboot is required to hear changes. I found this was not the case and I could tweak the volume as it was playing no reboot needed. Though you'll probably want to reboot after you find a good setting for your phone to save the changes.

If you want to change the volume of the phone you have to first look at the way engineering mode is organized. Choose your desired speaker output first. Do you want to change earbuds/headphones? Then choose headset mode. Do you want to change the main loudspeaker? Then choose Loudspeaker mode.
Then, determine what kind of sound you want to increase. Is it media (audio/video/music/etc)? Then choose media in the 'type' drop down. Is it phonecalls? Then choose sph. Is the speaker phone incoming call volume too low? Then set Loudspeaker mode, sph level 6 to a higher setting. Is incoming call volume too low on the ear speaker? Then set normal mode, sph level 6 higher.
You could adjust level 5 higher or level 4 higher etc. When you press the volume up it goes to a higher level. When the volume up button doesn't go any higher that is at the max (i.e. level 6). All the way down is level 0. Adjust how the volume sounds at different levels according to your preferences.
You may also tweak the microphone volume using the above levels as a guide. Callers on the other end of phone calls have described my mic as 'very clear' using the volume level above.
The settings above are pretty good for me but I may change them in time and update this post as needed.
Hope this helps!05-11-2015 11:42 PM
- I had 4.3 on my S3 and the volume was low during a call. I updated to 4.4.4 but the result was the same. The codes you give do not work on the S3. I can get service mode but that dont have any sections to change the audio. It has been rooted, is there anything else I can do? The volume works but maximum is too low.06-19-2015 01:31 PM
