Hello,

I've had the Ulefone Be Pro for few weeks now and is pretty happy about it. I spend quite a long time reading reviews and testimonials from people, so I was relatively well-informed about pros/cons. And yes, they fucked up releasing Lollipop quite significantly, but on the other hand I have a rockstable KitKat phone that I have yet to see one single crash on since I got it...

Anyway, one single thing annoys me pretty much: The volume when using headphones is low. It's not not-usable low, but it still annoys me quite much that I have to keep the volume at absolut maximum at all times to hear people. I use the phone with a pair of Xiaomi Piston 3, they provide pretty good noise-isolation, so it's okay...but still, always at absolut maximum.

I tried changing the settings in Engineermode -> Hardware -> Headphones. I tried several combinations and I have yet to see any differences yet?
I use the phone as my corporate phone and we are not allowed to root our phones. Does the changes in Engineering mode only apply when the phone is rooted?

Any help would be much appreciated.

Thanks

Hi magicx !

I have modified all audio levels with Mobileuncle ... this is my audio configuration (and I'm very satisfied about it) ... I hope that it will be helpful for you too. The Max Volume is 160 , but a lot of people advise against to set the max volume to 160 because it could damage your phone. Set the max volume to 150 is more than enough.

THE AUDIO SETTINGS:

Open Mobile Uncle Tools and open engineering mode.
Under engineering mode, go to 'Hardware Testing' and go to ‘Audio’.
Go to ‘Normal Mode’ (front speaker)
Under ‘Type’ select 'Sip'.
Under ‘Level’ enter these values (Value is 0~255)

Level 0 < Value 160 Max vol 150 (press SET and OK)
Level 1 < Value 176 Max vol 150 (press SET and OK)
Level 2 < Value 192 Max vol 150 (press SET and OK)
Level 3 < Value 208 Max vol 150 (press SET and OK)
Level 4 < Value 224 Max vol 150 (press SET and OK)
Level 5 < Value 240 Max vol 150 (press SET and OK)
Level 6 < Value 255 Max vol 150 (press SET and OK)

Apply the same settings (above) to 'Sip' on ‘Headset Mode’ and 'Sip' on ‘Loudspeaker Mode’
(Loudspeaker Mode is the back speaker).
Next, in ‘Normal Mode’ under ‘Type’ select ‘Mic’. Under ‘Level’ select ‘Level 0'.
Under ‘Value is 0~255' enter 255. For all levels, from level 0-6 set the value as 255 (there are 14 levels on my phone and I've set all levels to 255). This will ensure that your voice is audible to other person even when you turn down the speaker volume. Apply the same settings to ‘Headset Mode’ -> Mic and ‘Loudspeaker Mode’ -> Mic.
Next, in ‘Normal Mode’ under ‘Type’ select ‘Sph’. Under ‘Level’ select ‘Level 0'.
Enter these values under ‘Value is 0~160' for various levels.
Apply the same settings (above) to 'Sph2'

Level 0 -> 90
Level 1 -> 100
Level 2 -> 110
Level 3 -> 120
Level 4 -> 130
Level 5 -> 140
Level 6 -> 150

Apply the same settings (above) to ‘Headset Mode’ -> Sph, Sph2 and ‘Loudspeaker Mode’ -> Sph, Sph2

Next, in ‘Normal Mode’ under ‘Type’ select ‘Media’.
Enter these values under ‘Value is 0~255' for various levels.

Level 0 -> 32
Level 1 -> 48
Level 2 -> 64
Level 3 -> 80
Level 4 -> 96
Level 5 -> 112
Level 6 -> 128
Level 7 -> 144
Level 8 -> 160
Level 9 -> 176
Level 10 -> 192
Level 11 -> 208
Level 12 -> 224
Level 13 -> 240
Level 14 -> 255

Apply the same settings (above) to 'Headset Mode’ -> FMR, Media and Matv
Apply the same settings (above) to ‘Loudspeaker Mode’ -> FMR, Media and Matv
VERY IMPORTANT: remember to restart the phone after to apply all the settings.
IF WHAT YOU WISH ... I can post my original levels (stock rom) too.
