Display keeps turning on while charging - Samsung Galaxy S7 Edge Questions and Answers

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.

[Solved] Random screen on DURING charging

First off,
this is not about the screen turns on at the moment when the phone is plugged in/out
this is not about i want to keep screen on when the phone is charging
The problem I am experiencing is:
when the phone is charging normally, the screen turns off. But at random intervals, the screen suddenly turns on itself and turns off like when you turn it on just to watch the time and let itself go to sleep. However, I have not moved/touched ANYTHING...
What am i using?
Nexus 4 shipped from play store
stock usb cable shipped with the device
AC adapter manufactured by LG (P500) which I have used for 2 years across P500 and Gnex without problem
AOKP unofficial and franco kernel
Settings are correct
Display settings > Sleep > After 2 mins of inactivity
Daydream > Off
Developer options > Stay awake > Off
Suspecting the ROM?
Unfortunately, I also got this on everything stock, when I was testing the phone before I root and just some basic testing apps were installed (Display Tester, Speedtest.net, Z-device test, Stability test)
BBS and logcat?
Unfortunately during plugged, BBS tells me it has no logs
and I tried to turn on alogcat immediately at the moment the screen turns on itself, however no suspicious logs shown
Only when charging?
Yes, I don't see similar random-screen-on behaviour when it is on battery
I have done numerous searches around but sadly can't find anyone with similar problem... Is it my stock usb cable was faulty which reconnects power at random intervals? Is it android 4.2 feature to screen on when something happens?
Please tell me if you have insights about it or you have experienced before!!! thank you very much in advance
P.S. this is my current list of running apps FYI
Settings
franco.Kernel updater
Whatsapp+
Facebook (refresh interval = never)
Maps (location report = off)
Wechat
Line
Camera360
BetterBatteryStats
SwipePad
Avast! Mobile Security (used since Gnex and had no problem)
dodol Phone
Simple Calendar Widget
Smart Statusbar
Battery Monitor Widget Pro (already had problem before installing this)
Exchange Services (check interval = push)
Google Services x2
Light Flow
GO Keyboard
Might be a cable problem. I had this with my long cable but had since disappeared after switching cables. Good luck.

I don't think any app that you have running is the problem nor ROM or kernel that you're using. I think the problem is that either your USB cable is nor functioning properly or the charger isn't working properly (which is unlikely since you've mentioned that it had worked fine on previous devices).
If you have spare cable, try that. Also try another charger if that helps.

guys thanks for helping me confirm that the culprit isnt the phone/software
i was then inspired to inspect my AC charger and USB cable and found something totally RIDICULOUS..... -_-
i found out that the line "charged" on the lockscreen blinks for several times at the moment power goes into the phone
then i suspect that the phone is expecting AC power but the initial current is not enough hence making it blink
I took out an non-stock cable and try - similar behaviour
then i plug out my AC adapter from my wall and compare it with the stock N4 adapter... lol my 2-year old LG P500 adapter was 0.7A and our N4 should expect 1.2A as the stock adapter prints... things really get old these days just like the need of changing SIM card
I searched over my home for a universal travel adapter to test out the Stock N4 charger - no blinks of word, no screen on, both cables good
US adapters doesnt fit the power outlets here in HK so tomorrow ima immediately get a 1.2A local AC adapter and everything should be fine :laugh:
thanks very much again guys!

[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] Galaxy S4 won't charge

I should clarify the title by saying that trying to charge this phone is resulting in a number of odd results.
So firstly, I've tried using the wall-mounted AC charger. I then tried using USB on my computer, in 3 different usb ports. The phone was charging perfectly less than 24 hours before this problem began.
I plugged it in as per usual, and it didn't show the little lightning bolt on the batter icon like it should. It wasn't registering that it was plugged in. I tried plugging it into my PC, and it wasn't showing that it was connected via USB. In addition to that, my computer was failing to install the drivers for it. I went back to the AC charger, and tried a few different outlets, including one on a power strip. Nothing worked.
I searched online, and found that other people had this problem, and could only fix it by resetting to factory default settings. One person even had to do it twice to get it to work. So I did this, and it still didn't work. I tried charging my old phone with this Ac charger and cable, and it wouldn't work either. So I thought it must be a fault in the cable. So I dug up the cable (also micro-usb) for my old phone, and tried it. It worked just fine for my old phone, but my S4 still had the same problem, but with something new. It would say "Dock connected" but still not charge.
As of right now, it seems to be charging properly with my new AC mount and old usb cable, but I'm worried that this could happen again. Considering this seems to be a problem for other people too, what should I do about it? Is there some way to prevent this sort of thing from happening? Was it purely the other cable, given the fact that it didn't work with my old phone either? I'm on an extremely tight budget, and this phone is my only way of being contacted for job interviews, so having it in working order is very important. Any advice would be very appreciated!
Having exactly the same problem... couldn't find over the internet a solution yet or a position about it...
Affraid it's a hardware issue and have to send to the assistance...
Anyone know what to do?
Yup having the same issues - but i noticed only having charging issues when battery reaches 20% or the low battery notification pops up
it detects that a usb is connected but it wont charge
Solutions:
- dont let it go below 20 which is ****
- some people claim that if you use a 5pin charger instead of the 4pin which samsung includes solves the prob
Mine is a little more serious I think... haven't found a solution like that yet.
I have to connect/disconnect multiple times and it suddenly works.
But between those connects/disconnects it presents multiple problems, it appears on notification bar "Dock Connected", sometimes appears "Dock Connected" and on the notification bar appears "Suggested Apps (Anchoring)", other times it appears "Dock Connected" and the volume bar appears on the screen and stay there freeze (the phone works, but the bar doesn't disappear)... Sometimes the phone starts charging and suddenly stops, other times it says it's charging and if I remove the charger it keeps the charging symbol on the battery icon...
It's completely crazy, gonna take to service I guess.
Have you tried blowing out the usb connector on the phone with a can of compressed air?
If there is a minute piece of dust there it may be shorting something out - error that dock is connected. I know this happens to other phones, there was a big thread about it on the S3 forum. Might be a simple little thing like that...
Unfortunately that doesn't work for me, will send to service, let's see.
have you solved this problem and how?????

Yep, chalk up one more with the same problem!
At first I thought it had something to do with Aviate, a custom launcher from Yahoo (actually a pretty sweet one at that!)
But I guess not.
My work-around is to reboot the phone while connected. It charges fine while turned off and seems to keep charging when booting while plugged in.
Still... this is a stupid work-around and I want this fixed properly.
Any news from any of you guys?

Had this problem today. Suddenly out of nowhere "Dock is connected" message appeared after plugging the charger in and out. Tried to clean out the dock with stick and cotton on the edge. Then turned off and plugged in charger. Problem exists. Phone charges but stops regularly. It is very annoying when you dont know how to fix this kind of problem.
Any new solutions?
Right after this post, I froze the app "battery doctor 4.9.2" using Titanium Backup Pro (you can just uninstall it i guess). Then just plugged charger and now it's already Almost 90% without any interruption.

Amazing! I've dealing with this problem for weeks and internet didn't give me any good answer, but the whole problem was a baterry monitor apk that for some reason was interfiering with the charger. Thank you so much!
I had this problem too and in my case it was a hardware problem. When i start the charging it kept repeating the start proces of charging with the vibration and the grey battery icon(in case the phone was turned off). The battery icon with the green charging light just didn't showed up. I tried many things but nothing helped. I let the phone keep charging for the whole night but in the morning i saw that it didn't charged anyway!
Then i went to a local phone reparation shop(none official samsung) and they knew immediately recognized the problem and it was the usb/charging connector where you plug it in the phone. They fixed it in 1 hour for a cheap price and from then(i think a few months ago) it charges back perfectly. It seems it's a disease with S4's.
In my previous post I was happy thinking that all this charging problems were solved after uninstalling battery apk. But, in fact, my S4 charges very slowly after that incident. I have tried two other samsung adapters (galaxy s4 mini; grand prime). First one results the same (up to 5 hours charging), the latter was comparably shorter (up to 3 hours), but still slower than it used to be (2 hours normally). So I highly suspected the hardware might be the reason. Thank you for your information, now I will also have the phone checked at some local repair shop. And give feedback of course.

You probably got some water damage in your port. What you need to do is clean it. I used pure alcohol and a toothbrush for that. After that I flashed a custom kernel so I could enable fast charge true usb.
That's the reason your phone is charging slowly, it thinks it's connected true usb. So you need to boost the usb charging. After a few charge cycles I could revert back to my standard kernel and the problem was fixed.
I think ur right Lenny.
Mine S4 got wet last weekend and now i am also getting the " Dock is connected" message when i plug in the charger cable.
I can charge my phone but sometimes while charging i hear the sound go off and on what you hear when unplugging the charger.
I will try your solution and hope it will fix mine too. Thanks for posting ur tip!
I suggest you go buy a new genuine cable for an s4, the s4 does actually require a special cable capable of 2A charge rate otherwise you can end up in all sorts of bother.
Thank you all for sharing tips. I cleaned the port as suggested, then replaced my cable. Now everything is back to normal.

Same problem - galaxy s6
Hi there - same problem, on my 128gb s6. started this morning. Yesterday everything fine, would charge when connected via USB to both laptop and to regular samsung usb power unit. Have now tried 3 different USB cables including the samsung cable, 3 different usb power units and of course tried all 3 cables in laptop usb port. Have checked phone's usb port - clean as a whistle. Have rebooted both connected and unconnected. Started getting 'dock connected' message, now it just wont charge, although starts up fine. I take very good care of the phone, so no water damage or untoward shock damage (never get it wet, never drop it). Remaining battery charge seems to fluctuate between 30% and 40+ %, depending upon whether it's plugged in or not. If I turn it off, then connect usb cable, the phone just reboots, still not charging. I then turn it off and see no green battery charging screen, as I used to seen when connected but turned off. Should I just hard reset and take to repair shop? Still under warranty.
I would return the phone for a warranty repair. Software would not usually prevent the phone from charging when powered off.
As a final test, see if the s6 will charge wirelessly, assuming you have access to a qi charging pad and the s6 has a built-in qi receiver like the North American version of the s6.

Stuck in wakelock after plugging in the charger, until restart

Hi guys so I bought a nexus 6p a month ago and been loving it. I almost have nothing to complain about except this issue.
After using it a few times I've realized that sometimes the battery goes down in less than 2 hours screen on time while sometimes it lasts for about 4 hours screen on time.
After monitoring the battery usage regularly I've noticed that the phone never goes to sleep after plugging in the charger until the phone is restarted every time. So in short I have to restart my phone every time after I charge my phone to prevent wakelock.
While this definitely isn't that serious of an issue its still really annoying and the nature of the issue is really weird because as long as I restart my phone after charging the wakelock never occurs. I've tried uninstalling all the apps, switching off Bluetooth and WiFi but still no luck. I doubt it's app related as it only happens when I plug in my phone to the charger. Does anyone have an idea what's going on and any solution to this?
Thanks in advance
Is this always using the provided wall charger or a 3rd party charger. I've had pretty strange behaviour when u used a cheap USB a-c cable with my car charger, had to buy a decent branded cable in the end.
My phone refused to charge off the wall charger after I used the cheap cable until I did a reboot. It might have caused wakelocks but I stopped using it pretty quickly.

Galaxy s8 intermittently not cable charging

Hi!
My girlfriend's new S8 will intermittently not charge overnight. I'd say maybe 5 times since she bought it last month she'll wake up to an almost dead battery, while it's still plugged in. Not sure if there are any messages or anything.
This is using the charger that came with it.
Anyone else experience this?

I don't charge my phones overnight, but haven't seen it with my S8.
There could be a process of a particular app that is using resources and it makes CPU work harder and/or the charger isn't giving enough power to keep things going.
Of course do simple stuff like checking out the cable/charger + try another one if you have, try different outlet....
Before putting it on a charger: Items 1 - 2 do every time you charge the phone - it is very helpful.
1) Clear all recent apps
2) Restart the device(this usually gets rid of any app that are stuck)
3) Also try to charge not overnight by couple of hours before going to bed, so it would be easy to monitor what is happening.

Thanks for the reply, but we'll find it's either slow charging (it actually says slow charging), or it won't even show it's charging/plugged in. I've tried clearing recent apps and restarting.

I had the same issue as you had yesterday
It seems that samsung did some update that checks the amperage current that it charges and if its low or unstable, the phone stops getting charging.
Try use original adapter and short length type c cable like the original, it won't happen.
