Crackling sound when calling and charging at the same time? - ZTE Axon 7 Questions & Answers

I was making a phone call for my grandma couple days ago while quick charging my A7 and even she heard the crackling noise when we spoke on the phone. I am not sure if slow charging does this too but when the phone is not being charged there are no issues whatsoever.
Has anybody else noticed this?

I noticed it in my car too... connected via bluetooth and charging using a Qualcomm 2.0 (note - 2.0 not 3.0, so the previous generation) charger.

Unplugging charger disconnects call?

A friend was at my house this afternoon charging his Galaxy at my bar. A call came in, so he unplugged it, and the phone immediately disconnected the call mid-ring.
After he called back and finished his call, we did some tests using my home phone and were surprised to see that both of our phones do this.
Has anybody else seen this? Seems like a pretty silly flaw.
Nope. Ive unplugged mid call on all three charging sources (USB, car, AC) while talking and have never dropped on. Very strange bug you've encountered. Was it with the same charger or different chargers? If same then maybe something with the charger?

He may have hit a button in the side while unplugging it...
Sent from Samsung Vibrant
No accidental button presses, as I said, we tested this so we paid attention to what we were doing. Two different chargers, two different phones -- both using the stock Samsung chargers.
Note that this happens during the RING... not mid-call.

[Q] Wireless Charger turns N4 off in the night

Hope someone can help with my wireless charging issue. This issue is happening with a stock Orb so I purchased another Qi standard charger but same result.
I put the N4 on charge at night wake up in the morning and the phone has turned off and is only around 80% charged. Also very hot to touch. Obviously this is not good when you are expecting the alarm to wake you up. And also even if the phone has turned off it should still be charging I would have thought
My phone is stock standard 4.2.2 and using the wall plug that came with the Orb (1.8amp). It is charging up perfectly well on usb overnight.
So it was doing this with the Orb and I couldn't return it RMA as I purchased it outside of USA so I bought another Qi charger and guess what.....the same thing happens. So at least I have isolated the problem to the phone and not the charger
Any ideas
Interesting. I tend to avoid using the Qi orb when I'm not monitoring it. It does tend to get hot and makes me a bit nervous. So sitting at my desk working and need quick access to my phone while it chargers, orb; sleeping and performing my nightly charge / alarm, plug.

Yes, I wonder if it is actually the heat that is causing the phone to shut down. But then when it is shut down shouldn't it still charge the battery?
The Orb was a present from my lovely wife so am dead keen to use it :laugh:
If you've isolated the issue to the phone I'm guessing you can get it swapped out w/ Google. I've heard they have a pretty good system for that. Just curious, do you have a case on the phone? Your heat theory makes sense, I wonder if the case is causing it to overheat and shut down. I'll try charging mine when the phone is off and see if that works.

Yes, I have a case but I have tried it with and without. Keen to hear if it works OK. Thanks
OK, I cycled my N4 off and placed it on the orb and nothing happened. While it still was on the orb I held down the power button for a few seconds to boot it up. Rather than turning on it switched to a charging mode. Another hold of the power button turned it on. I'm wondering if by default it does not charge unless you deliberately cycle it to the charge mode. Have to do more research on that.

[Q] Wireless Charging on/off pulsing at night

Hello again friends!
On my phone, see sig for details, I have noticed whenever I place the phone on my QI Pad, while it does charge, The 'power source' is reported as AC, instead of Wireless. I believe this to be the cause of my problem of at night, when full charge is reached it chimes to confirm full, then drops 1%, so chimes to start again, and repeats.
I tried holding my QI Receiver (After market) to the terminals on my friends S3 I9300 and it showed up as charging Wirelessly, Can anybody tell me what in my phone tells the ROM what the power source is ?
And If they know a fix for what im experiencing. for example, if this is kernel related, any recommended kernels that support 4.3 ? c:
Thanks heaps in advance

I'm using the stock Samsung charger with a third party QI receiver module in my S4. It's correctly identified as a wireless charger when connected, but the problem with intermittent charging at night that you describe still appear. I believe this problem is inherent to the technology. However, I "solved" it by deleting the charger connection sound as well as using Tasker to completely dim the screen at night. This way I'm no longer bothered.

I can turn off the vibrate and sound nd screen on in settings, But I wanted it to identify correctly so I can use Tasker, and Daydream, only when on wireless.. :c
Im thinking it may be Rom specific.. in which case Ill ask my good old friend i've never really had direct contact with Vertigo

Display keeps turning on while charging

Hi does anyone else have an issue while charging the phone where the display keeps turning on every 10 seconds and then turns itself off?
Bill
No. It sounds like a third party app is causing that.
To check, boot into safe mode and try again.
That happens with one of my wireless chargers. I guess when hits 100% then drops and back to 100% Not sure if your using wireless or not.
I was not on a wireless charger, on the other hand I was on my old HTC changer that I have on another room. Was not doing it from what I noticed with the Samsung charger.
*** tried a different HTC charger and it seems to have stopped turning on, wonder if that HTC charger is throwing out different power

Or maybe it's got a short in it. My car charger was doing this on and off this morning. And I can tell the wires going into the base are going bad.

Yes I have this issue! I just bought this phone a week ago. I've been using the fast charger included with it. Every time I charge with the fast charger, no matter if the phone is on or off, the display will turn on and off every 10 seconds or so like it keeps getting disconnected/reconnected from charging. I tried charging my phone with a regular phone charger and the display no longer turns on and off. What's going on?

Yes, been having this issue as well (happened before I rooted). Only happens when I use my old HTC chargers, doesn't happen with the included Samsung fast charger, or a 3rd party wireless charger. Have tried turning off fast charging in Settings, disabling the Stay Awake when charging option, and charging in Safe Mode - makes no difference. Would be great to know what causes it!
Yes I'm having same issue! Only when I use my old HTC charger! Any other one it doesn't do this! Would love to know a resolution!
Its the older chargers, like the HTC, not having sufficient current for the S7s bigger battery.
Probable solution
I had the same issue with my S7. A week after buying it the display kept lighting up randomly during charging. I switched chargers to an older Huawei and the issue went away. Last week the issue came back. I tried blocking apps but it did not work. What worked for me was clearing the USB cache. Settings > Apps > Show system apps > Enabled > Search for USBsettings > Storage > Clear data and cache. PS - This also works if the phone wont charge due to moisture detection.
I had the same issue with my Samsung S7 Edge while charging using one of my dual monitor's USB Port. I just switched to another USB Port and it stopped doing it.
Weshp, thanks for your very specific answer. It seemed like it was working (my phone stayed off for a longer pause), but after about a minute, it started coming on and off again and when I check, there's data in the USBsettings again. If you have any other ideas, I'd love to know.
My Galaxy S7 has been doing this on and off for a long time. I suspect the cause is overheating because the battery is charging too fast. The lower power chargers won't charge as fast so they won't heat up the battery. If I'm wrong, I'd sure like to know how to fix it.
I can't find the path to clearing the cache so I haven't tried that.

Moisture Detected only on dock S7 Edge G935F

Hello, I'm experiencing this weird issue with my phone, after last update few days ago I put the phone on my Samsung S4 dock and the pop-up saying that charging has been disabled because the usb port was wet or dirty, but the phone was perfectly dry. Then I tried to charge it with a USB cable and IT WORKED and with wall charger (quick charge) as well but when I put it on the dock the damn moisture detection alert pops up and it doesn't charge.
I also tried with another dock, Samsung Tab4 dock (the big white one) and nothing changes, but both docking stations work with my girlfriend's S4....
I'm going crazy, please help me....

Had the exact same problem with my s7. I think it must be a bug in the update. Kept getting moisture detected when in desk and car dock but not on normal charger. Had to flash back to previous firmware to fix the problem. Going to wait until next update and hope the problem is fixed.
Had the exact same problem as well. I did not flash it back to the previous firmware version and was hoping that the next update would fix the problem but unfortunatly it didn't. I updated my S7 a few days ago and the problem is still there. I keep my fingers crossed that they will soon fix it in one of their futur updates.
Same issue
I was googling for a solution and came across this thread so thought I'd reply and see if it's been resolved for anyone else.
Whenever I plug in to my car charger I get the "moisture detected" message. I can charge fine from a wall charger. My phone is the S7 Edge. It started doing it after the last update. My phone has never been in water, or even splashed. It's frustrating, due to my job, I use the car charger far more often, and now I can't.
I was also searching the web for a solution and came across this thread. My phone is a Samsung Galaxy S7 (no edge) and has the exact same behaviour since I've updated it in early September.
I am trying to charge it on an official Samsung dock from a few years back (Galaxy S3). Everytime I get the moisture detected error, however it charges fine on every other charger I have. The latest October update didn't fix this problem
Same issue

Hello, I experience the same issue. Whenever I plug in the phone to my car it detects moisture although the phone has never been in any contact with water whatsoever. Wall chargers work perfectly fine. Is this issue connected to the latest update?
Are there any updates on this topic, any solutions?
Thanks a lot!
having same problem with my s7. Both of my Motorola car chargers cause this error message to occur, although the chargers work fine when charging my car's Bluetooth speaker. my other chargers in the house work fine also.
I feel your pain
Exact same issue with a brand new, mint from the box S7 Edge. It displays the "moisture detected" message on all three docks in my house, yet is fine charging off a cable, with an adaptive fast charger, regular charger or even the wall wart that came with a Google Chrome Audio. It looks like something the dock sends out to tell devices that attach to it is confusing the phone firmware. I had a Note 4 prior to this, and the dock nullified the adaptive smart charger function, so clearly there is something more than just pass thru going on with the docks. It did charge the Note 4 though, albeit at the slow rate.
Same here, S7 edge charges perfectly on all cable and cheap China docks, but NOT on the official Samsung EDD-D200BE. The only difference I see is that all cheap dock are really pass thru and this Samsung dock is trying to do something with audio (has a audio jack) and other intelligent things.
Probably too intelligent for their own S7.
