[Q] Q9 wireless charging problem

Hi!
I've just received the Q9 Wireless Charger from a manufacturer in china.
It's Qi-compatible and have been seen working with the Nexus 4.
Mine does not seem to work.
The manual says a led should be shining green when it's ready to charge or when it's charging. It's hard to read the chinese translated manual.
Mine just shines red and blue constantly and nothing is happening with the phone.
Am i doing something wrong? Do i have to activate it in my phone? I've tried putting it in any direction in any place on the pad.
Someone have a clue?
EDIT:

I have the Energizer Qi charger and when I place the phone on the charging plate, a light over the plate shines a steady blue until charging is complete. Flashing multiple colors (especially if one of them is red) probably means there is a problem with the charging system or the power.

That's what i'm afraid of. The thing is that the leads shows blue and red all the time, even when the phone's of the pad. Updating with a picture.

try position it with the centre?

Done that too...

Is the power cord connected securely? Maybe it's not pushed in completely (or shouldn't be pushed in so far).
For what it's worth that's not the Qi symbol on the charge plate.
If possible, send it back for replacement. It seems to me that those two LEDs should light up for no more hen a few seconds after the device is plugged in and then turn off until they nerd to indicate some condition like charge complete or error.

I have the Q9 charger for couple of days.
It's takes many tries of locating Nexus 4 on chargers surface to make it work.
Many times (most of my tries) I unable to make it work at all.
I am wary disappointed with this charger. It was waist of many.
I shouldn't have to be such cheapskate.

Q9 Qi-charger broken
I had mine for about a week now. Used it with my Nexus 4. Charges the Nexus quickly, but when at 100% it stops charging. Only when unplugging charger and re-plugging it, it will charge again. One morning Nexus was at 77% while laying on charger. After a few times unplugging, the connector was pushed into the charger leaving it useless. Do not buy!

Just got one too
I have to place my Nexus towards the top of the charger for it to activate and start charging.
Took me a while to find the correct placement.
My pad is supposed to flash blue when its charging - It starts charging and then seems to stop, then start again, then stop - not sure if this is normal or not.
So far i'm pretty disappointed with it, I assume because I got a cheapy from china that this isn't the normal experience with QI chargers, but I doubt I will be buying another until I see someone else with a much better model.

(Q) Using Samsung Galaxy S2 charger with the Nexus 4?

Is it safe to use the charger from the Samsung Galaxy S2 with my Nexus 4? It fits perfectly. Will it deplete the batteries health or anything? Thanks!

That's the whole point of making a standard charger. Of course it's safe, any micro USB charger is safe.
I'm charging my Sony Ericsson with Samsung charger in one room, and Nexus 7 charger in other room, and my SE charger is in my backpack to carry around.

It's safe and it's better you use the Samsung one rather than stock nexus 4, since it has deep problems! (red light of death)

I've used the charger of my Samsung Galaxy S2 a couple of times. Works fine.
So do other chargers, like my old Nokia 1.2A charger. And charging via Qi (Philips pad) and USB port of a PC works fine too.
Just make sure you use good quality chargers, and not fakes.
And yes sometimes it's hard to differentiate between the two...

I'm sure any micro usb charger is fine. I use different chargers all the time. If it fits, it'll charge.

The charger has nothing to do with causing the "red light of death".

If you'll look through Q&A there are several threads about it. People panic and create them instead of looking for others with the same problem. The phone shuts off and gives a blinking red led. Most of the time it's fixable

I Think My Nexus is Dead

Hi,
I have a Nexus 4 for about a year, and until the last 2 months I had no problems at all. I started noticing my phone shut down after about an hour because of my battery swelling. I replaced the battery and I had great battery life for about 2 days, after that it drained super fast.
A few times my phone shut down and a red LED started blinking, I fixed it thanks to a thread in this forum.
But now, I had 100% battery and it turned town. I tried to start the phone but nothing happened. Connected the charger and pressed the power button a long time until a red LED showed but for a long time.
The blinking LED didn't worry me because I knew my battery drained and it fixed but now the battery is full, the LED lasts for long time and no matter what I do, nothing turns on the phone.
I don't know what to do and I'm really close to throw it away.
Please help.

I've sent it to a lab and they said my voltage component of the motherboard has gone and they charge me for 100$. Is it possible?

Well, you can find new logic boards over 100$ on eBay, but with the replacement fees and the cost of a new logic board, the price seems reasonable...

Dead Nexus 4

unfortunatly my Nexus 4 fell into water and Iv'e tried the rice trick and it didn't helped. now after few weeks when I plug it to the charger I get a solid yellow notification light (sometimes it gets red too).
I just wondered what does it mean. it says the phone is just dead?

How long did you charge it?
Yellow light normally suggests it's charging. Let it charge for 3-4 hours and then see. But before this make sure that there is not water inside the phone.

I didn't actually tried to let it charge I 'll try it now.
it just light up when I plug the phone in. it's more orange light but the first time I plugged the phone it was red.
I replaced the battery yesterday from my friend's nexus 4 and it's still the same (the battery was half charged on his phone).
but the phone can be dead even though the battery charging right?

It's not responding, but Iv'e noticed that the light is still on when I took out the battery.
what does it mean?

Phone burned through cable

Has anyone had this before?
My phone burned through the cable I received with it.
http://imgur.com/ZLXNU8E
I tried charging it today, but the charging light didn't turn on. Didn't think much of it, but when I removed it from the charger after 10 minutes, I smelled burned plastic. And part of the cable got stuck in the phone. Had to pry it out with pliers.
Phone doesn't charge anymore, but it still works.
Really glad I noticed it in time, otherwise I could have had a fire on my hands... Was really hot
Sucks pretty hard to be without a phone for the time now.
Guess I'll start annoying the hell out of google and LG until they fix it?

Yes, a couple people have had this already:

Yes. I have heard of this.
And it scares the h*ll out of me!

I'm not a fan of fast charging due to this issue. I've seen it happen on other devices as well. Batteries are not meant to charge at such rates. I'd rather have a slower charge personally

This is why whenever I charge my phone, I keep the AC/Cooler/fan on of that room, keeps the phone temp low and helps in faster charging.

Whut? This is actually very concerning....is this a usb type c problem you think? Or does this happen with other phones too?
You should report this to LG

This needs more media attention. I don't think anyone has zeroed in on what's causing it yet. This could happen to all of us for all I know.
Need a response from Google.

Definitely not charging my phone over night anymore, Google and LG need to look into this.

I absolutely adored my galaxy note 2 back in the day, probably would have kept it for another two years had it not burnt to a crisp overnight. I woke up and my bedpost was smoking, almost burnt myself touching the note 2 when I woke up. Took off the back and it was absolutely destroyed, some parts completely burnt. Shame this is happening to people, its a scary thing to wake up to

I suspect this isn't very widespread, but it's kind of scary. I've always charged my phones overnight, and don't really want to stop now.

I had this happen with my old HTC Desire way back when. Woke up in the middle of the night to a burning smell. Could hardly touch the phone it was so hot. Battery was swelled up to the point it was deforming the back cover of the phone.

i just purchased the 5x on saturday and paid for 1 day shipping so hoping to get it tomorrow. but this is making me worried... i might get a usb type c charger thats rated at much lower current to help prevent this instead of using the included 3A charger. or get a standard usb to type c cable and use a regular 1-1.5A charger.

I use a USB-A to Type C cable with a Samsung 2.0A charger for overnight. Just cause I don't need to fast charge while I'm sleeping.

Same thing happened to my LG nexus 5x. The phone works but does not charge anymore. Very bad as LG claims that it is out of warranty due to customer usage. Really bad!!

Speaking generally, this almost always has happened, for years, to people who pull the cord by the wire, not by the plug. My wife is terrible about this and she goes through 3-4 cords to my one.
Anyway, that may not fully explajn this problem, bug it'll sure makd it more likely.

Well. I just googled and I found this article. My nexus 5x just burned yesterday and the worst was that everything was wood, even the floors. It almost started a fire at my home yesterday and I am mad because of that.
There is a picture I attached and I'm returning it tomorrow because I had it for almost 3 weeks now.
