So I have a QI wireless charger I got on amazon. It works perfect. Also use it with nexus 7. Today I noticed when my phone was on the charger, something caught my eye and my phone was shuffling through apps, opening Google now, getting driving directions and such by itself. As if someone was using the phone. Every time I put it on the charger this happens now all of a sudden. Its kinda comical. I laugh and watch what all it does each time. Any idea what could being causing this to happen when placed on the wireless charger?
Your phone is being haunted.
It could be an issue related to overheating. Was your phone got to touch when this happens ?

No, not more than normal using the wireless charging. It only does it when I place it on the charging pad. Its almost instant. As soon as I take it off, it stops. I don't see how the wireless charging could be causing it to perform task on its own. I'm thinking it is haunted.

This happened to me today
I had the same thing happen to me today while using a Nokia qi charger. My phone just started registering random screen presses, which resulted in the device launching my music player and starting to play a song. Just happened the one time, though. Haven't been able to replicate it.
Yeah i've seen it twice before with the orb. I think it has to do with static electricity.
are butesQ
Same thing - I got a phone and a Qi charger from Nokia. All happens while the phone is on the charger
But.... I don't see how heat can produce text that makes sense. Text that has nothing to do with me or my apps. More details here: http://forum.xda-developers.com/showthread.php?p=45560693
thats crazy lol...
The only way to keep it from performing random task, is to lock the screen before placing it on the charger. The screen will turn on and off but since its locked, it won't actually perform various task.

static electricity and capacitative touch screens
I have been wondering about this kind of problem, and research is pointing to an electrical interference with the digitizer.
A lot of users have posted that the phantom touches are happening on a localized strip or area of the screen. You can view this as it occurs by enabling "view touches" in developer settings; of course, some report issues so extreme (usually because the phantom touches are appearing across the soft buttons at the bottom of the screen) some might have a considerably harder time accessing this option.
I have noticed that I am able to replicate this issue immediately after charging - however, it is occurring after a wired charge, and only in the last week (I bought an N4 a over a month ago sealed NIB/HW vers.: rev_11). Because the connection between Synaptics digitizer ribbon and main board is solid, and because the touches only appear at the microUSB/charger I/O end of the device, I am left wondering if there is a contact/shielding issue going on, or if it is some other problem allowing static to build up and discharge through the digi.
More research is needed, including reviewing bug reports and logcats. What other diagnostics could be run to get more information on the electrical status of various components to help track the issue? Have any other E960 users experienced a phantom touch issue? How many have seen (maybe) a correlation between charging and the weird screen/digitizer events?
results of testing
attempted fix 1: re-locked the bootloader, then OEM unlocked, affecting a FULL WIPE of the device. RUUed from occam stock (7-zip, fastbooted everything from bootloader to radio by-the-book), beginning with old JB and then up to 4.3. the problem "quieted down" for a full five days, and then flared right back up.
attempted fix 2: pulled the phone apart, disconnected battery. cleaned the digitizer connections with 90% Isopropyl. applied a tinfoil ground, first to the metal chassis (which honestly made my armhair stand up a bit when it turned on), and then to the grounding/shielding covering the NFC pcb. the problem "quited down" for 2 days, then flared right back up.
attempted fix 3: called LG. said, "this phone's f*$#ed; here's the ESN." LG guy tells me the screen's already been replaced on this handset. it was a refurb, "but it weren't our guys what applied the new screen assembly that's giving you all the bollocks" - it was the carrier, and that warranty just went out of date yesterday. THERE IS OIL FROM SOME FINGERS making dodgy contact between the digitizer in the assembly and the chassis, and this results in RADIO INTERFERENCE THAT FLARES UP the phantom touches when there's a perfect storm of COLD (static!), VOLTAGE IRREGULARITIES (mains/cables/municipality!), and USAGE (lots of cache!)
attempted fix 4: can anyone recommend a trustworthy online vendor for a properly grounded screen assembly? I'm going to finish the teardown and replace the full assembly, and when that doesn't work out, I'm going to throw this glass static machine on the ground.
has anyone else been doing testing/have any positive results that stick longer than a business week?
screen going berserk when placed on qi charger
I have had this same issue yesterday, but only on one of my phones.
I have an E-Ceros One (Chinese MTK Octacore phone, twin/clone Ulefone U5) and my old (now my wife's) SG Note 1 (GT n7000).
Bought a qi receiver from eBay for each phone that plugs into micro usb port of the phone and receiver pad lies inside between battery and back case, and a cheap qi charger pad.
Put the receiver in the Note, chuck it on the charger & starts charging - no problems! (other than it does get a little warm when charging)
Put the other receiver in my E-Ceros One, lay it on the charger, starts charging but the screen goes berserk - definitely looks like the electromagnetic field is making the screen digitizer go crazy.
I have sort of found workaround/s though:
- either turn the phone off first and put it on the qi charger, OR
- the qi charger I have is rectangular, and if I sit the phone across the width of the charger, i.e. so the top and bottom of phone are sitting over the sides of the charger with nothing underneath, it starts charging and screen doesn't go crazy. If I wait ~30 secs I can then turn the phone so it sits along the length of the charger and screen doesn't go crazy - I'm thinking the electromagnetic field "settles" after charging for a few moments.
So yes, it's weird
I have a Galaxy s4. When I plug it in to the wall charger, it says, changing paused, temperature too low. I have an app to read my phone temperature and it says give or take -5 c. I've tried a master reset and tried looking online for solutions, I also tried putting my battery in another s4 and it works fine, the only way I can charge my phone is to use a heating app for about an hour Do you have any suggestions on how to fix this glitch? i tried calibrating my heat censor but i don't think it worked, the heat sensor in my phone doesn't seem to work. Any help you can give me is greatly appreciated. maybe if i could get an app to force charge my phone, or disable my heat sensor all together? i tried finding a diagram of the mother board so i know exactly were the heat sensor is and i also had no luck. PLEASE HELP!!!
Hello,
Unfortunately I do not have any pictures to show the issue so I will try to explain the problem as best I can.
I recently replaced the screen and bezel on a LG G2 (D802) Moving everything accross from one bezel to the other went fine with the only difficulty I had was removing the battry from the old bezel (The battery got a little bent, but nothing major).
After putting everything back together in the new bezel/screen I started getting a strange issue. The phone refused to turn on and if I plugged the charger in it would show me a battery symbol with a thermometer in a yellow triangle. After a few minutes it would then turn on.
When the phone is on, it will charge and work perfectly fine until the phone is turned off next.
Looking online I have read that after changing a screen on this particular phone some people have reported that the battery reports its temperature being -30c.
Does anyone have any idea what is causing this issue, and if it is the battery temperature sensor, where is this located?
Have you been able to fix thi problem? i am having the same issue after changing my screen
I'm having the same issue. sometimes when i'm getting the -30 temp issue, I'd literally bang the phone a few times and it would correct itself. while showing -30 temp it would not charge... with the charger connected, it would remain at the same battery level.
I'd appreciate if someone would find a way to hack the charging function not to look at battery temperature as i'm sure it does. I think this is something that runs deep within the device - not a simple OS parameter since the device wouldn't even boot up if it's "too cold".
not sure what i have to replace to fix this issue. I never removed the battery, the issue started after I changed the screen myself (kept the same chassis)
Hi,
I have an issue with my device.
Basically, when I try to charge it, I get the error that the temperature is too low.
I read that the issue could be my NFC-antenna/wireless charger (which is the same part), however, I can still read all of my NFC cards, so that seems to work fine.
I have replaced the charging port about 6 months ago, and it does not seem to be the issue this time.
When reading the temperature with an app, it says -20 degrees Celsius, so that is obviously the issue.
Does anyone know how I could fix this?
I have 2 friends that repair phones and I'll try to fix it in the next few days and I'll tell you how it ended up. I also read about the NFC module and bad contact in it, but we'll have to see. I'm currently heating it up to see if that works. So far it doesn't, but I'm very cautious not to damage the phone and maybe it's not warm enough.
I had my NFC module replaced... bummer...
Have a Sm-T530NU that has misbehaved for a long while, originally the OEM battery was thought bad. Yet after it was changed to a new off-brand battery and working on and off for a year and some, the tablet has started misbehaving again, mostly not charging and turning off alone. And recently has started showing the temperature warning icon while charging while off.
So, I've opened it again and digged down, and discovered the battery connector on the PCB wasn't well soldered, the contacts danced in the pad, so I retouched the soldering with flux and a little new solder and it seems ok (I can recheck again later if needed be), so I tested the original battery with multimeter and seemed acceptable, so I installed the original battery back. Charged it for a while, and, again, warning icon for temperature while off, and it switches back and forth between charging and warning... I turned it on, and it works, but throws an error once in a while about being too hot and closes all apps... this, I think should be something related to cpu heat and not battery one... (also wasnt charging during this). So, I read online that some of these tablets with a modem have a service menu (*#0*#) but of course this one has no dialer, so I've tried several programs to try and get into the service menu, my idea is to see if it's possible to recalibrate temperature sensors, for battery and for cpu, but I've not been able to open the service menu by any means (the last mean I have is trying an intent initiated by am but the tablet is not rooted and there's permission issue for asking an intent of uid 2 from uid 0....).
My questions are:
1) Is it possible to get to the service menu of this model somehow? with or without rooting? Is it possible to recalibrate sensors from it?
2) Should I recheck the battery connector? would a battery "overheat" (caused by a bad connector connection to the sensor cable, or a miscalibration) cause app shutdown during run? or is it related to cpu/gpu overheat? I see some phoen models (S2) can cause this message from torubles with the usb connector/pcb, this doesn't sound too logical on my case, but, is it a possible source of problems for this tablet too?
3) If it IS a cpu overheat (though tablet feels cool to the touch) is there anything can be done to help with this issue? micro disipator maybe?
Thanks for any advice. I'm willing to try odd or hard stuff to fix this.
