Problem with the speaker on Xperia 5

[sofun2]

I just received my new Xperia 5, and I met the problem with the speaker. It's the top speaker, it gave sound with the base speaker together to give a stereo sound. But once the top speaker was sounded the whole body vibrate. I've already disabled the function of dynamic vibration . It's just the body do the resonance with the top speaker, and when I tried to block the top speaker with the top speaker , the resonance got weaker. Have you guys had the same problem? When the phone body vibrate the sound quality is destroyed and it feels really uncomfortable when I held my phone, it's really not a performance of product that Sony should have.

I think that's because of Dolby Atmos and might be fixed with an update. Have the same problem and my mother too.

I am gussing that you mean while you are playing audio through speakers , you could feel the sound vibration on the back of the phone. If that's the case , this is not a glitch but I believe this is sometime intentional features of the phone.

This will gives you a louder sound as the back to the phone will gives off sound as well.

Hey there, it sure gave a louder sound , but the sound started to become broken as well. Meanwhile, the vibration from that resonance made my hand already uncomfortable while holding.

Have you met the same case as I did ? Because,  I want make sure If it is a designing default or just my bad luck to have bought an imperfect phone. And Sony doesn't accept a changement of my phone which I just recieved just for one day, it gave only repairing solution. It's just unfair to a consumer,  who bought a defective product and cannot change it but ?repair? It ?
