How Increase Xolo Q700 Volume

XOLO Q700 Low call volume , Low audio volume, Low media volume - FIXED.
The only thing i was disappointed with this excellent phone was the low call volume and audio volume. I followed the instructions below and additionally also tweaked (increased) the volume levels for Media, Microphone, sph2 and other 'types'(for some max is 160, for others it is 255,
just re-adjust all levels starting with 255/160 for level 6 and gradually decrease for other levels), also when adjusting media levels I increased the Max volume to 160 from 128... or so, which was default (this is greyed out for the type 'sph' but gets enabled when you select other type....'media' i guess). After restarting, i can see a marked improvement both in call audio quality/call volume and media volume.

Instructions :
 1. Enter Engineering Mode – Dial *#*#3646633#*#*
2. Go to Hardware Testing>Audio>Normal Mode.
3. Select “Sph” in type.
4. Select “level 6″ in Level.
5. Enter 160 in value.
6. Press Set.
7. Restart the phone.
It will increase your volume when you put your volume
to the highest level.
If you want to increase your volume in all levels then
choose from “level 0″ to “level 6″ and enter value u wish. max is 160, and min is 80 .
