bottom speaker quieter than top speaker

[Andî]

hi. first sorry for my bad english, I am from Austria^^

i got a few days ago a new X Compact (build 34.2.A.2.69), but is it normal that the top speaker is much louder than the bottom? if i listen a youtube video etc. the sound from bottom speaker is very low und muffled.

in german forum i read that the speakers must be play ~1 hour and than the calibrate themselves, but it didnt helped.
I tried every audio setting, and factory reset, but always the same

here i maked a little video from it with a speaker test that i found:
(hope it works :D)

BUT if i go to accessibility and activate the "mono audio" both speakers have the same loudness at this speaker test (but the songs are nevertheless on top much louder again)

do you think its a hardware issue and should i send it to sony to repair?

thanks in advance

sound perception is very subjective,. I suggest to have an identical device for comparison. you may go to your service center/ retailer and compare with another X compact.

try to run xperia diagnostics on settings>about phone

or run the phone on safe mode to see if there are any changes

hello and thx

i tried it with diagnostics, safe mode, and service test (*#*#7378423#*#*)

but always the same (bottom speaker is much quieter)

i think that could not be original so

can please someone else go in the service menu and test the right and left speaker?
is there much volume difference, or are both same loud at your X Compact?

thanks again!
