    I bought my G6 few months ago, June 02, 2017. After a few days of using it, I tried playing music at a max volume. After 3 to 5 minutes, I noticed that my speaker heats up like 37°C to 40°C.
    I asked few of G6 users if they are experiencing same issues like mine but they said they don't.

    Do you guys experience same issue while using your phone's sound at maximum volume? Thank you!

    Your speaker heats up or the phone temperature ?

    I don't have heat up problems with mine.

    I don't see how your speaker can heat up. Could be your phone heating up and traveling through the speaker area.

    Hi guys, this is where the portion of my phone heats up whenever I play music at max volume(please see photo)

    LG G6 Speaker heat issue-g6-medium10.jpg

    I just normally play music; my entire phone doesn't heat up at all, only the red circle at the photo.

    Hi devaa,
    What kind of app are you using for monitoring? Currently using CPU-Z but I think it only gives me thermal report of my Battery, not the phone itself.

    Thank you!

    So the red part and the blue part both heat up ? I use system monitor aswell as cpu-z...

    A speaker should not heat up like that... about the only reason I can come up with is something wrong electrically with the speaker module that is causing the circuitry to heat up. That's bad news... could mean that the part is in danger or shorting out. I would contact service and get that addressed.

    I agree, best to get it swapped as soon as possible.

    Only the red part heats up when playing music. The blue part normally heats up when I'm using certain apps such as Facebook etc, blue part ain't issue to me

    I went to the store yesterday. Tested their G6 demo unit, played a music for a couple of minutes while the volume is at max. And yes, the demo unit's speaker is heating up as well. Tried it on 2 demo unit.

    It's risky that they will open the rear part of my phone to check it since the rear part is embedded to the phone and cannot easily opened unlike v20 which has non-removable battery. And it would take 2 weeks(approx.) to get my phone back.

    could be circuit. our repair guy thought the same when a friend and i went there just a weeks ago.

    Correct..... Because s speaker, especially one that small shouldn't generate heat. In fact the coil or element would burn out before generating that much heat.

    I think I just noticed the exact same issue with mine. Where did you buy your device?

    I suppose it depends on how much heat... I'll have to try it out on mine to see.

    I noticed this same issue the day I took the phone out of its box..the exact spot where the speaker is located on the back glass heats up (hot enough to feel it with the back of my palm) whenever I play songs via the speaker.. I Googled this issue early July but it seemed I alone had this issue...

    Speakers can heat up pretty well if it's overpowered.. I.e if the amp is driving the speaker coil way higher than it was designed to work with.. Probably caused by excessive bass tuning of the speakers via software cuz the Speaker does have decent bass, loudness and clarity for it's small size.

    I watched some disassembly videos of the LG g6 and the only component I could see within the heating area was the speaker so definitely it's being overpowered and hope this doesn't result in the speaker failing in the long run

    Excessive heat will burn out a speaker coil or element. Still find it strange that it would generate so much heat. I wonder if the water resistance design is a contributing factor.

    Did you try connecting the phone to a Bluetooth speaker or headset and playing music for the same amount of time to determine that it is in fact the speaker, and not coincidentally something else? Just a thought.

    Yes the area only heats up when playing music via the inbuilt speaker

    Hi guys. I recently purchased a G6 and my phone has similar problem. Whenever i play a game or music or video at max volume. The area near speaker heats up. I already returned one phone back to amazon due to this issue. The new one i received has same problem. Anyone has any idea what is causing this issue. The fact cannot be denied that speaker is quite loud especially when compared to my nexus 5

    i guess its normal.....even mine heats up..but not to abnormal degree

    the speaker for lg g6 is sealed separate so if water enters to speaker compartment in any case it won't get to the mainboard. the phone uses a 24 bit dac and it can be using more power yet it can not cause all that heat up. i believe the water seal causes heat build up.

    i won't give it for repairs, because they would check and mess up the new prone, also compromise the water seal. you said demo units heat up too, so don't worry much. better use moderate volume or headphones.
