    Default Concerned with LG G3 overheating.

    My phone has gotten hot three times now and the screen dropped down in brightness. I don't understand this. I love this phone but this is a real concern. Only 3 days left in my return period. Very confused.

    What are you doing on the phone when it gets hot? Gaming or just basic stuff?

    Don't worry, if you are using it for a while with bigger apps it's quite normal, especially if you are charging it.

    Screen brightness dropping is super common and you shouldn't be worried. And at the end: It's only -10% brightness.

    My device hasn't had your issue but then again, I haven't watched videos for a prolonged period of time either, just quick minute clips on youtube. I do have some 720p ripped movies so I'll start watching one on my commute to work tomorrow and see if anything happens. If I were you, I would just take it back to get some peace of mind, especially since you still have 3 days left! Won't hurt to just swap it out for another!

    I'm listening to music on YT and browsing Chrome in dual window on my balcony and because the outdoor vis sucks on this thing, I had to pump the brightness and just got limited.

    I use autobrightness and haven't had any overheating issues and this is after having the screen on for extended periods of time.

    Take it back. I got mine yesterday morning and mine barely gets warm with heavy use. I've tried everything but gps. Of course gps gets every phone warm.

    Were you on wifi or LTE? I watched a few videos on LTE once and the phone got quite warm around the buttons, camera area very quickly. I would not call it hot but warm. The screen did not dim because I had disabled that feature.

    How do you disable the screen from auto dimming?

    The whole thermal throttling thing is a pain i.e. LG’s decision to turn down brightness when it gets hot. However there is something you can do and which I have now done for two weeks with no adverse problems. Turn it off! Put this in the phone app: 3845#*400# and then scroll down to 'high temperature property' and switch to enable and do the same for 'thermal daemon mitigation'. Please note my model is ‘400’ so this will work in the number sequence above. For models with other numbers I am pretty sure you just substitute and put that number in e.g. 855.

    Substitute the model number i.e. I had the ATT model so I entered 3845#*850# into the dialer.

    Do y'all think I should take my phone back under insurance? All I have done within the last 10 minutes is browse here, send a text, receive a text (and I mean one each) and send 1 hangouts message and I am at 105.3*F at the time of posting this....
    I have a screenshot of it going up. I can't even open my GSM app to take a screenshot of the thing going up...

    Just an update my phone is cooling itself down now even though I haven't changed what I am doing.. Same number of apps open and everything... Concerned with LG G3 overheating.-8176.jpgConcerned with LG G3 overheating.-8174.jpg

    These screenshots make it heat up again but 105*f is just too hot.... I thought I could ignore it but I barely want to take it outside in this humidity when I am inside in a cool house and it is doing this....

    " the hundreth time" - get a replacement. Maybe just the battery is bad, but it shouldn't be getting hot like that. I would try a CPU usage monitor also to see what's going on. Also a system tray app.

    Quick question because I've been thinking about it for a while today.

    Today I got 130 degrees (still have around that, 140) by only browsing Tumblr and checking out this forum for a while doing nothing else.

    Is it normal? Its not the battery - the battery feels cool, it's the top part of the phone around the camera.

    Same issue here with the phone overheating near the top of the battery. I am going to get it replaced today under the 14 day exchange/return period. Hoping the new phone doesnt have these issues.

    I let it cool down and closed all running processes except the android ones.

    Now I'm listening music and reading this forum through the app and the hot on the top third part of the phone is really noticeable - almost uncomfortable and I'm only using the phone for like 10-15 minutes with minimum automatic light.

    Is it normal - should I worry about that? (Currently battery is 95 and cpu is 135 degrees.l
