Xperia Z3 Compact Sound

[AndreiArseniu]

The sound in Xperia Z3 Compact, with the update to lollipop has been drastically reduced. I did a repair with pc companion, but i couldn't hear the same volume as when i was using Kitkat on my z3. In addition to that, with the repair, my battery started to deplet very fast and was heating even if the phone wasn't charging 41.3 degrees. So i did another repair, and fixed it. But the sound, is way low. It has 2 speakers and the Asus Zenfone 2 that has one speaker is way louder. I am hoping that with the next update, the sound to be fixed so i can enjoy my phone.

Hi @Arseniuandrei

Welcome to the community.

The first thing I would suggest with the speakers is checking to see if this is a potential hardware problem. To use Xperia Diagnostics:

• Go to Settings > About phone > Diagnostics.
• Tap Test device.
• Select the Loudspeaker
• Follow the on-screen instructions.

If it fails the test have a chat with your contact your Local support team as it will need to be serviced.

Something called Cell Dub Deb, it was using 34% of the battery, and now 4% maximum.

I did a test, and my loudspeakers are good. But surprisingly i found that the accelometer and the light sensor doesn't work. Although when i use adaptive brightness it works. But i have no ideea what the accelometer does. @uliwooly i answered to the wrong person, you can see it down.

Furthermore, sorry for double reply, but don't think that my speakers are sounding very low or something. They just don't sound as loud as when i had kitkat installed. I can surely remember that my screen was shaking a bit when i was using maximum volume and now it barely vibrates at maximum sound.

Yeah thanx, if we have one :)) i bought this phone from a website and it's imei is from Japan, it was meant for Asia, and in my town i have no Sony Center, only in Cluj there is one. I'm just hoping it's something from the update, because i dropped it only a few times, like 8 times, and from small distances, and it's true i,ve washed it cause it's waterproof. I will try cleaning all the dust, maybe it's from the dust that's blocking the sound

I'm sorry to say this but it might be a hardware issue, if you repair the phone with PCC and you experience the same issues, its a hardware issue.
