Hey
ive noticed a weird thing goin on with my phone...the screen stays on while chargin and it also randomly turns on while in stand by mode. I cant rly see any pattern in it...its toaly random. When i press the power button in order to go into the stand by mode, it goes back on...but again this happens only sometimes. Anyone knows what it could b?
Ill rly appreciate any help from u guys...
PS: could the cause b the ROM/radio?
for the screen staying on while charging: go to: settings - all settings - system - power - Advanced. There you have "on external power". The 2 settings for you to change as you want. Also can use advanced config (needs .Net Framework 3.5 Compact). About your other problem ... might be some notification or something ...
I noticed this behavior too with my old phone (HTC P3300) when I used a USB charger other than the original. There was no such problem with the original charger. I haven't charged the TD2 with a non original charger yet.

Hey guys,
A friend of mine recently bought this tablet and everything was running very very smooth, until he received the OTA to 3.1 . Besides the wifi bug ( very easy to get rid of ), he is now experiencing a really really weird touch lag. Let me explain: as soon as he plugs the tablet in the charger the touch gets really unresponsive forcing him to slide/touch several times before the tablet detects the input even if the system keeps working as it should, ie no slowdowns etc.
Funny things is this bug only shows up (for now) when he plugs the charger in university while not happening at home.
Has anyone experienced the same? Im starting to think that the charger plug has a defect and is in some way affecting the touch system ( electric\magnetic stuff ) leading this to an hardware related problem, but I want to be sure so maybe we will try to flash something (Are there Acer tools to flash full stock roms?). Tablet is running original rom and recovery, I just messed with the wpa_supplicant files but I dont see how this could be related.
Thanks in advance guys
When my screen is off and I turn it back on when I switch from charger to battery I get laggie for a minute. Same on my notebook and my cell.I believe its to do with changing some power profiles/settings. If you recover in a minute or so its prob fine. If not watch running apps. If you see something running all the time.use a freeze program to trouble shoot if its a rouge app.
Hope this helps to troubleshoot your isssue
If im wrong with this information please just give your correct response to the open. Do not bash my openion.thanks
saw one other thread with similar problem...

110 volts
I live in indiana.
When you plug your charger in the fram becomes hot. 110 volts to earth. Just check it, can't be good.

Fram? 110 volts? What are you talking about?
More details - please. "110 volts to earth"? Not making much sense.
My guess, and its just a guess, is that his charger is somewhat faulty and not regulating the power correctly. Ask him if he plugs straight to the wall at university and into a power strip/surge protector at home. If he is, then I would imagine that the power strip is regulating the voltage enough to let the charger work, where the wall outlet is making the charger fail. I'd try a new charger if one is available and see if that fixes the issue...or take a surge protector with him to university and see if that also takes care of it. If he isn't using a power strip at either place, then we are back at square one.
Have you tried going back to an unmodded system to see if that works? (by that I mean remove/undo wpa supplicant).
I have no idea what that problem could be as it seems hardware based by just reading what you typed, but it could be software too which is called into question by the little mod you did.
What I find odd is that it works in one place and not another.
Does it happen when Wifi is off completely? (Just asking because I'm thinking if it has to do with the wifi mod you made, perhaps turning Wifi off and testing would show up something).
I'll just tell you what I would try in that situation.
1. Go back to a stock ROM, fully. No mods, no root, no hacks. Preferably one designed for your region. (We have no idea if any of the hardware in these units is different based on region, which is why I never recommend putting a ROM on the device unless it's 100% certified to be originated from a device purchased within that region).
2. Factory reset. (It doesn't fix everything, but it fixes most software glitches - especially when they're caused by outside sources like apps or settings mess ups).
If it still happens after that then you've at least ruled out all software suspects.
The frame of the a500 is hot. The charger is none polorized so makes no difference which way you plug it into the wall or extention plug is the same. Check your charger to earth and you will see line voltage no mater where it's pluged in, and don't have to be pluged into the a500. They need replaced. Just meter from the outside of the charger plug to ground and you will see the problem. Might not be on all chargers, but I would check mine.
Just check you charger plug to earth without the a500 pluged in, the problem is not in the unit or software just the charger.

I had an issue like this with a palm pre, and the only solution i could determine was that i was using an offbrand charger that wasn't supplying the right voltage/amperage and causing flakiness with the electrical charge on the screen. maybe the charger is damaged, or they're using an off-brand one?
Ty guys and sorry for the late reply. Yeah I was thinking about reverting back to the stock system but unfortunately I'm not very familiar with the tablet scene not having one and since he is a little frustrated atm about his situation maybe flashing a recovery to flash a stock rom isnt really the way to go. Isn't Acer delivering any tool to flash a full rom just to try if that will solve the problem?
Thanks again!
So wait someone is getting 110v from ground to the metal frame of the tablet?

Same issue
I found this thread, and this is exactly what's happening to my tablet. When it's plugged in, the screen becomes very unresponsive, and it's very annoying. I can't charge it and use it at the same time. It's not even like galaxy tab 10.1 or ipad 2 where the battery life lasts like 10 hours! I am extremely frustrated about this issue..Mine has this issue at home. I don't bring charger to school, so I don't know about that. I'm really surprised that only very few people actually have this issue..
electrical grounding no good
Anyone has a solution to this?? Should I buy a new charger? I don't want to just waste money if it's not gonna fix the problem.
Thanks.
I had a similar experience to all of this when I was recently travelling by airplane. There were charging outlets (US-style 2-prong) on the back of each seat and my tablet absolutely REFUSED to respond properly to touch when I plugged it in. At the airport, in the hotel, at home, and everywhere else I've used it, it worked properly.
My conclusion: touch screens on A500 are very sensitive to electrical problems. I suspect that an airplane's electrical system isn't as "standard" as everywhere else, and whatever the difference was (a grounding issue, or a voltage regulation issue, or whatever) caused the touchscreen to freeze.
My suggestion to the poster and others with "when I plug in the touch screen stops working": go to another location (i.e., a friend's house, work, school, a coffee shop, etc.), plug in and see if the same problem happens. If it does, it might be your charger, so try someone else's A500 charger at a bunch of locations and see if the the same problem occurs.
I would guess that most people with this problem (not the "when I plug it in it gets for a few seconds" problem, but the "touch screen doesn't work when plugged in" problem) will find a solution lies in their power source, not the A500 itself.

Thanks for your suggestion. I'm actually moving to a new home tomorrow, so I'll try the new power outlet. Hope it won't have problems like right now..

I have run into another problem related to touch screens - mine doesn't work on airplanes. I think that there is some sort of pressure differential issue - the screen works fine on the ground, but once I open the tablet when the plane is at altitude, the screen just stops working - it doesn't matter if the tablet is plugged in or not.
Annoying to say the least. Last night I pulled out my wireless mouse to use the tablet, and a stewardess noticed this and told me to put it away as wireless devices aren't allowed on airplanes.......
Any suggestions?
Hi all,
I just bought an LG G2 (D802 international unlocked version) and the behavior when plugging in the charger cable is very strange:
When I plug in any charger (tried 4 different ones with different cables incl. stock), the phone is not charging.
BUT, there are a few strange things happening:
1. On the lock screen it shows "Charging"
2. In the settings menu under the battery menu it shows "not charging" (this is different from being unplugged, then it shows something like "discharging")
3. Sometimes the popup comes up when I plug it in, but not always.
3. When I turn the phone off and plug the cable in, the display lights up (also the LED) and it shows the "charging" battery symbol.
IN ANY CASE, THE PHONE BATTERY IS NOT CHARGING!
Here is what I tried so far:
- Used 4 different chargers & cables
- Tried to charge via USB
- Did a factory reset
Nothing helped so far.
I suppose that its a hardware failure, but maybe someone has a different suggestion/solution?
Only thing i can recommend is maybe do a factory reset to see if that corrects it which i doubt it will. Other then that i would have the phone warrantied then.
If its a software issue then that is at the kernel level. I would assume its a hardware issue though

I got a replacement unit, it was a hardware issue.
The same problem i am facing with my G2 Sprint LS980 and i am pretty sure this is not hardware problem because my phone had signal issues and LG charged repair fee around US$ 55. My phone was not rooted before repair and also my phone was charging fast too. It has installed ZVD7 ROM. But once i get my phone it was completely changed. They rooted my phone, They converted my ROM from ZVD7 to Cloud G3 2.2 and they also installed TWRP recovery. But still phone is not charging same like as you posted. I just noticed another thing phone is perfectly charging in TWRP recovery mode. Therefore i am 99% sure it's not hardware issue. 2nd issue is that phone is also not detect with my PC. I tried different drivers but failed. Anybody can help me or suggest me any suitable ROM and provide me correct driver or PC suite?
having same issue , have u solved??

Not yet Dear...It is the piece of junk for me. Now my ROM has been deleted. I want it back
I have the same problem. The phone is acting very inconsistent with charging after I replaced my broken display. This is the second time I replace the display, and it didn't cause any issues the first time. Basically, my phone won't charge more than maybe 2% over a period of 12-16 hours. The phone does not discharge as others have mentioned in previous posts.
No one seems to have a solution to this problem. Some people online are arguing that is it a "security measure" LG have installed into the phone, which makes it impossible to properly charge the phone without an official LG charger/cable. However, I never used the official charger, but been using various chargers and cables without problems!
But now comes the really weird part. I decided to take off the backcover, and then plug in the charger to see if pushing down on different parts would somehow fix it (loose connections etc..). But before I got around to test such hackery, I plugged in the USB and the phone suddenly started charging! I proceeded reproduce the problem/solution, and the result was very confusing: no real charging with backcover on; perfect charging with the backcover off.
Would anyone here on XDA have any ideas as to why this is happening? I've been thinking that the connectors on the backside on the cover might have something to do with it. Not having the backcover on does not seem to affect the phone at all (i can use it like I would without the cover).
TLR: My phone won't charge with the backcover on, magically works when the backcover is off. I suspect that it might have something to do with the connectors on the back of the cover.
Maybe putting the back cover on the phone is causing a grounding problem or shorting a circuit. Maybe put some insulating material on the inside of the back cover and then put on the phone?

Yes, I thought about doing this, trying one connectors at a time. Do you think that the sticky part of a post-it note like do? I don't have electrical tape lying around atm :/
Anything that is non-conductive should be fine since it is just a test.
You could also use a non-sticky piece of paper between the cover and the phone's components.

So you solved the problem?
I have very same problem decon89 described - I replaced screen and cannot charge it properly. And even worse: charging is possible with the phone being switched off completely. And after phone is charged - I cannot turn on the phone unless i open back cover and unplug-plug battery cable. Phone MAY turn on without unplugging-plugging battery, but it is blind luck. Yesterday i accidently turned off my 100% charged lg g2 and could not turn it back on during whole day. If someone has a solution please share it.
Hi everyone,
I'm so sorry for not following up on this thread. I haven't fix the problem yet, but it worked for same time, then started acting up again.
I've put a few strips of electrical tape on the bottom part of the phone, behind the black plastic thing. I did this because of an issue with my display having a loose connection. This fixed the screen problem, but the charging fault came back.
The idea of putting a piece of paper between the battery and cover did not work at the time, but I'll try it again tonight.
As I'm writing this, the phone is charging with the cover half off. It works, charges, no problem. I can even use the phone even though the bottom part of the cover is off.

same here with my phone when i take off the back cover it started charging.
Hello, mates, have a few problems that I want to discuss.
First of all, the screen issue. I don't believe any of you had such thing but sometimes when I wake the device, the touch screen is just crazy. I mean I touch somewhere specificaly, but the screen 'gets' the touch somewhere else. Plus, sometimes, I don't know if it's lag or smth but the screen starts moving through pages even though I didn't touch the screen. I happens after device has been asleep for a while. Reboot solves this problem but it is a problem even trying to select the reboot option. Sometimes it's like some side of screen isn't responding. Tried different roms, still nothing (the stock one also did this).
Then there is charging problem. Well, it's not a problem, actualy. My nexus charger got broken and I bought a moderate price new not asus charger, which states that the output is 2.1 A. But my nexus can't get more than ~600 mA output with that charger. Using a phone charger 1.1 amps output everything is fine, the battery monitor shows about 1000 mA while screen is off. So the question is, whether there is a kernel/rom that would have a fastcharge feauture (like some phone kernels have) or there are some of them but I'm not smart enough to turn fastcharge on?
I tried franco's, faux, oxydos, kangaroo, M-kernel.
I have installed stock v20f via OTA and did factory reset to my phone to avoid any problems.
While charging, the touch screen goes crazy and does not register many times the right touches. It is very apparent when I press and hold the home soft button. It does open random apps!
When the phone does not charge, everything works as it should. I have updated the touch firmware many times via the hidden menu but it did not work. I have done factory reset once again but nothing has changed.
I did not have this issue with v20b. Any ideas ??
might be coincidence and the charger has gone bad
can you try another?
I checked again today, same behaviour..
The phone works without problems when I charge via usb cable in computer. I have used an HTC charger with 1A and again worked ok.
Maybe the 1.8A coming from stock charger produce too much heat that make the touchscreen probelmatic ? I say it because we are in the middle of the summer and I live in a very warm country :
The charger otherwise works ok so I cannot make a warranty claim I suppose.
