[Q] High pitched noise coming from charger? - G Tablet Q&A, Help & Troubleshooting

Has anyone noticed a high pitched noise coming from their charger? I finally pinned down the sound today. It stops after unplugging/plugging in, but returns soon after.

Once and a While
it only happens to my charger once and a while , for me, I noticed if I leave it unplugged for about an hour it stops.. Idk what makes it happen tho..

It happens when you unplug it from the gpad.

It happens to me even when the Gtab is plugged in

I haven't written this in a long time and it will help bunches of folks:
Notice that the model number on the charger is MPA-630.
If you Google that you will find it is not too hard to find and not too
expensive if you need one. I believe it is commonly used with digital
picture frames.

My charger has been buzzing as well. It really bugs me. Im wondering if it has anything to due with the led light on the charger. I might try and take it apart tonight.

Just got the Gnote - Awesome but got some major/minor issues already

Hi all,
I'm gonna make this quick
I just got the note about 2 hours ago from Best Buy. The bestbuy guy setup everything for me so I got to play with it while walking to the mall with my wife.
I noticed some few things already which gives me concern .. so here goes:
1) (Major Concern) The phone is warm/hot. I've used my friends SGS2 before for two hours straight and it didn't get warm. My Gnote, however, after playing with it for 15 mins, I noticed it getting highly warm. I put it to my pant pocket and I noticed heat from my legs (that's how warm it was).
2) (Minor Concern) As soon as the Best Buy guy handed me the phone, I've played with it for maybe 1.5 hours total (on and off and not straight 1.5 hours). It was 50% when the guy handed it over to me, now the phone is almost dead 10%. So I used the phone for 1.5 hours (actually maybe less) and it took 40% already. I just thought it was in factory charge and I think it is normal. I'll do further investigation after a full charge.
3) (Major Concern) So now that I have low battery, I charged my phone using the charger that came with it. It does not charge! I've tried a different wall outlet and it still does not work. The cables are all good and there are no loose stuff. However, I tried to, unplug - replug afte 1 sec - unplug - replug .. and I did it for about 10 times and it worked - charged it for 5 mins. Unplug then replug and it won't charge again. I had to do the unplug replug routine to make it work again. I plug it to my Computer and .. bam .. 1 second it charges. I think I got a faulty charger here.
4) (Minor Concern) The free case is ugly .. lol
So is the warmth that the phone emits is normal? Again, I wouldn't consider it hot. It feels like you are sick with a fever kinda thing.
Please let me know if you have the same experience as I may got a bad batch.
Thanks!
I think you might have a bad battery dude. You should go back to best buy and get them to replace the battery. Getting warm is normal, getting hot is not.

Also...you can use any usb charger to charge your note, as long as it has the micro usb plug that goes into the note (standard micro usb). It may not be "optimal" to use anything other than the provided type, but they will work. I've used iPhone chargers to charge my samsung phones in the past. At the very least, that would allow you to rule out the charger.
Thanks for the tip
But I have an update. I actually had it charged for 45 mins .. then I tried to unplug it .. and replug it. Now the charger is working already. I multiple different outlets and it is now working. Maybe it was just an initial fluke .. but still that concerns me why it happened.
Anyway, with regards to warmth/heat ... I don't think that the battery is the one causing this heat. The warm area is concentrated around the 8 megapixel camera lens. Not where the battery is placed (lower part of the note). Does anybody know where the Snapdragon processor is placed in the device? Is it close to the rear camera?
Thanks
EDIT: Another Minor Concern: It did not come with earbud headset phones. Is it normal like that?
Battery is going to be bad until you go through a couple cycles battery life.
Yes. Getting warm after using it constantly for more than several minutes is normal, especially when watching video or gaming. It should never get hot but it will get warm. It will get even warmer if it has a case on.

Mine was warm when I first used it, after having it for a few days it no longer gets warm.

Thanks for the input guys.
Yup, I was watching twitch.tv (starcraft live stream - flash based) and that is when I felt warmth but even after ending it .. it took a very long time to cool it down (maybe 15 mins).
I'll observe it a little bit more. Should I leave it charged overnight?
Just use it like every other phone you have owned

The heat is most likely concentrated there because the camera sensor is glass and metal, therefore transferring heat more quickly than the plastic back to your fingers. I've had a similar problem with my infuse.

One thing people always forget is they tend to play alot with their new shiny toys... Give it a week or two and you will see dramatic increase in battery... Another thing is the brightness... Lower the brightness on the screen that should also help!

[Q] Random Water Droplet Noises

Dear All.
I have had the SGS3 for about 2 weeks now. I am wondering if other people are experiencing Random Water Droplet Noises when the phone is not in use (As in idle / sleep / screen off etc.)
I am quite often woken in the middle of the night to the water droplet noise even though the phone is not being touched and the screen in off... it is very random an can occur any time of the day or night.
Any ideas? Maybe Singal/Wifi drops-outs?
Cheers LD
yes! but i get random 'plugged into charger' noises. bleep-bleep.
there has to be a way to disable plugged into charger noises. my old evo car charger is loose. therefore the s3 wants to continuously pause my music from bluetooth to let me know. Of course I will get a new charger, but either way that is annoying.

Electric Shock While Charging

I've recently been experiencing electric jolts from my phone, especially when then phone vibrates while charging. At first I thought the jolting sensations were due to tendonitis but soon realized it's definitely electricity. Just wondering if anyone else has been experiencing the same thing.
Sounds like you have a faulty charger... get it replaced ASAP because that's not normal at all.

Runs way too hot under most use cases

I know all the reviews said this phone got slightly warm due to the screen, but in my nearly year-long stint of owning this phone, I find that remark to have been grossly misrepresented. When charging, my phone gets extremely hot on the power button. After charging, it takes a good 5-10 minutes to cool off. While the phone is hot, (and I mean HOT,) the phone hiccups, stutters, and can become totally unresponsive. Applications act up, etc.
When I attempt wireless charging with my add-on receiver, things get infinitely worse. I cannot charge with the screen on and data connected.
In my car, I connect via BT to my car, my audio receiver, and my OB2 scanner. That doesn't seem to be a problem, other than BT being sometimes flaky. I have a wireless charger in my car, but I only used it once -- no point. Now, even with my 2.1a charger, I cannot keep my G3 topped-off while using GPS and streaming Spotify. The phone practically melts. Things are better when I'm blasting the A/C on it straight from a vent, (and worse if I try to use my heater in cold months.
Basically this thing is in a perpetual state of overheating. I have had three of these. My last unit overheated so badly that the screen became discolored. You might say that I expect too much from my phone, but my M7 had no issue, and my S5 did not overheat. I had to give up the Sammy for other reasons.
I have made various tweaks in the past in attempt to counter the sluggishness due to heat, but that's dangerous--and likely why my last phone actually failed. I decided to leave that alone and deal with the crippling slowness. Even something as simple as swiping a word on the Google Keyboard becomes impossible.
My question to you guys, is do you notice this burden on a daily basis? Perhaps the average person that doesn't need a charger all day can keep this beast cool? I am strongly considering the S6 because of the reports flooding in of how hot the Snap 810 runs compared to the Exy. What are your thoughts?
I haven't seen this behavior at all. I've had little blips of hotness, but I almost think it's more environmental in some cases. Certainly not while charging, and I routinely leave it plugged in while I'm using it or watching Netflix or something. I'm sure you've thought about this, but are you sure it's not your charger? Does it overheat after a full factory reset (i.e. out of the box)? If not, what specific add-ons and/or ROMs do you use?

Due to the nature of DC, the charger cannot be the culprit in terms of overheating. Not staying topped off? Sure, but not the heat. The phone regulates all of that.
You are telling me that you can stream Spotify (highest setting for me,) and Google navigation, and your phone doesn't get blisteringly hot? I've been charging on the cable (instead of wireless,) to get my phone up from 93%, with the screen completely off, and it's pretty warm on the power button right now.
I am running stock ROM, (though rooted.) I have used various G3s, various ROMs, completely stock, various chargers, you name it. No matter what, this phone gets furiously hot when the screen stays on. Even using it as a clock on my desk causes it to heat up like no one's business. Streaming a movie causes it to get pretty damn hot. It seems like the environment of the car being warmer, and GPS being used with data is the main culprit. Like the internal heatsinks/paths become overwhelmed.

A simple solution might just be buying an external charger and spare battery combination and never use the phone for charging.
I have always bought external battery chargers and hot swapped a fully charged battery and put my dead battery on the external wall charger when I go to sleep.
Hope this helps.
(I've been buying Anker chargers & batteries on Amazon with success)
I think you're right. However I likely won't keep this phone much longer. S6 Active or G4 are calling my name...

problem with the headphone socket or sound

Has anyone has problem when listening to music using the socket built into the main unit, sometimes whiles listening to music, the sounds seem to move to the left with the left side being louder, not sure if it's the socket or the some problem with the sound chip, but moving the plug of the headset is not the cause of the problem, but you need to pull the plug out and insert back in to get the sound normal.
sometimes just pluging the headphones in also cause the problem.
Yessss! I thought it was my headphones!!!
I have had the exact issue with my G5 also! Exactly as you described it, I had to unplug and replug the headset to get it to go away. I was using Skull Candy Smokin' Buds....you? I actually went out and bought the LG Tone Pro bluetooth headset instead.

I have a few IEM listed in my sig that I use, all expensive ones, so i don't think i will use a BT IEM to replace them, also cable IEM produce better sound for Hi Res sound, I have also found out that you can skip to the next few tracks/files and go back it will go back to normal, but in all case we shouldn't have to do anything to cover up the problem, I think it's a software problem, but my G5 is going back today and i'm getting a new one through a instore 14 day exchange policies.

Yeah...But this is the second one I've had that issue on! Coupled with the flaws in the glass on the Titan screens...and the silver I had freezing and not turning on...this quality control is really crap on this phone. And that sucks, because I love this phone more than any Samsung I've had!

my first had scratches on the silver line on the case, second had a white burn mark in the screen, and can be seen with all colors, this is my third one, not totally perfect, but I have the advantage of checking the unit in store for problems including dead and bright pixels, but the sound problem was only noticed a few days ago and I thought it was my IEM, but it happened a few times, I should have my B&O unit soon, but this problem should happen whether its hardware or software wise.
I just had an issue with the FM Radio - it kept saying headphones not plugged in! I pull them out plug them back in, and it was OK again! I am using my G4 headphones too so even the same make!! I hope I don't need to return it GRRRR
@jreed3786
I got a replacment phone yesterday, at first I though it ok on this unit, but the problem is there and it's on they same song file, therefore I think the DAC actually can detect this problem that may be it related to the actual file, could be a bad conversion causing the phone to perform like this.
that being said, I have a DSD file that starts to buzz when it reached the end of the song, it happens on the V10 and now the G5, and the time length on the file shows like -9206:-30, whiles played on other units it's ok.
You guys didn't push it in all the way. G5 for some reason has a lot of resistance on the port. I had same experience until I noticed the gap and decided to give it little more force. It clicks in hard and didn't have any issue after that

I know how to plug the headphone plug in, it's not that issue, it's more like a compatibility issue, I have comfirmed this myself numerous time.
Headphone jack issue and more
So I've also suffered from the issue with my headphones plugged in. My left channel is quiet and my right is loud. On one occasion the left channel crackled and completely died. Unplugging and plugging back in my headphones causes the phone software to correct itself. This happens at least every other day. Then, my phone became sluggish a couple days ago and started to freeze and suffer random restarts until last night when it froze and entered a bootloop on the startup screen. I pulled the battery and let it sit for a while and plugged it back in and it entered the OS but was sluggish. This morning I attempted to use messenger and it froze again and entered another bootloop and then died. I took it back to T-Mobile and I've only had it 18 days. They took it back under their 20 grace period and I now have my second G5. This same issue was prevalent in the G4 and LG has recognized that issue. I hope I'm not in for another letdown on this second phone. I just divorced Motorola... Where to next?

Not implying you don't know how. Just saying G5 has port that is tight. No pun intended.

that's ok, i didn't mean't for that either, but may be it stood out too much, I apologize for that, the actual issue is compatibility with the music file and the DAC, sometimes the dac can get really sensitive and pickup minor errors in the files to cause these problems, previously the few files that had the problem has been removed from the phone, no problem since.

So the audio issue I was having is the same as the other posters on this forum. One channel with a low level and the other with a normal level and then having to unplug the audio cable to reset it. However, the ultimate failure of the phone is not. I was sharing with everyone what happened to mine and perhaps I should have started a new thread with that issue alone? I haven't had my second phone for even 24 hours yest so only time will tell and I will post and findings related to the audio here. I use my headphones during the work week so that is when I will know for sure.

Hope you get a good unit, I've been through like 9 units, thats includes instore checking and two units I took home, the second unit I have now without any problem.
all sorts of problem, not just the sound.

Hmm. Very interesting. Thanks for the info. I did see many complaints with DAC on G5.

Exact same thing happening to me, will pan most of the sound over to one side making one ear quite loud and the other quiet. I find if I pause, switch to another app, than back to whatever music app I was using it usually resolves the issue. Hoping the B&O module helps but doubtful considering this seems software related. I'll probably just deal with it this way.
I have the Same issue via aux. Restarting Poweramp mostly helps

I bought it yesterday
Headphone jack is very very loose. I tried to different earphones.whenever i touch headphone jack headphone gets disconnected. Any one with this issue
Only problem with mic enabled headphones
Same problem though my normal headphones work fine. When i use my headphones with a mic it only plays the right channel. I have not always had this problem but seems to be lasting a lot longer today. Normally fixed itself in 30 seconds but has yet to. I tried restarting phone with headphones in, then again with them unplugged. Havent found a solution. Does the B&O module work?
