A couple of months ago, one of my co-worker's Palm Pre phone attempted to swim in a pool and drowned (electronically anyway). My co-worker replaced it with a Samsung Galaxy S2 and when he got it he was complaining about how much he loved his Palm touchstone inductive charger. Basically you just stick the phone near a little hockey-puck thing and magnets align it and it starts charging without connecting any wires.
We thought about it and had this great idea to mod his new SGS2 phone and at the time we thought we were the first to think of this. So, I bought an inductive charging kit on Amazon and we both mod'd our phones and I'm very happy with the inductive charging system.
While lots of people have done it for lots of different phones, this thread is about the i777 and I haven't seen any mod instructions out there for the i777 SGS2.
First you need to get a Palm Pre inductive charging kit. Go to Amazon and search for a Palm Pre inductive charging kit. They run less than $10 including shipping (yeah, seriously, I couldn't believe it either). I paid $8.35 for mine. While you are there, get a Palm Pre AC adapter... the kit is finicky about the AC adapter and most of mine didn't work with it. So that's another $3.70 (inc. shipping), so you are now up to $12 or so.
Once you get it, it should look like this:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And inside it looks like this:
Open the kit box, and you will see a touchstone that you stick on your desk that is the charger and then the Palm Pre case back cover with the inductive coil on it. Peel off the inductive coil very very carefully as well as the four silver circular magnets and try to leave everything intact. Set it aside because when you put it on you want the contacts to line up.
Now comes the fun part, taking apart the phone, soldering the wire, and then routing the wire.
To take apart the phone, your best bet is to watch a Youtube video (that's how I did it), but fundamentally, unscrew the 7 small silver screws and then carefully, use your fingernails (best) to work your way around the gap in the edge of the plastic. Or - if like me you don't really have much in the way of fingernails - use a guitar pick or a thin credit card... like a store shopper reward card. Slide it into the gap and work your way around... not too hard. Don't use anything metal or it will scuff the plastic. Just start in a corner and work your way around, be patient and don't try to take them apart until you've worked all the way around. And if this description doesn't make sense, then watch a i777 disassembly video on YouTube.
Once you are done, you need to solder a wire to a resistor at the bottom. There's a close up here:
You could try to solder to the VCC pin on the USB connector but it's tiny and I personally thought the resistor was much easier to solder to without risking shorting any pins. I suck at soldering so if I can do it, others can too. Just get a fine tip for your soldering iron, get it hot (but not red hot), put some solder on the wire, and then touch the iron to the wire and then the resistor quickly. Do it quickly to make sure you don't damage the resistor or the PCB. It took me three tries but I got it.
Then route the wire.
You can see the wire route. I routed right... if you are looking at it yourself, you might think the the left side looks better, but it's next to the antenna and I thought the right side was less risky. I routed down, across the speaker (the bare black gap at the bottom is where the speaker is), under the PCB, then crossed up, and then dodged the screw slot in the upper right of the battery compartment by tucking the wire under the plastic there. But you don't have to do it like this... do it any way you want (although I'd steer clear of the antenna), you just want to route from the VCC resistor at the botton up to wherever you want to put the contact.
For the ground connection, any of the screws, or the sim slot metal or anything else works. I used copper tape and just routed with the tape to the screw in above the upper right of the battery compartment. But it doesn't matter. The metal of the SIM card slot works too... whatever you want. Ground is easy.
When you are done, it should look like this (more or less):
I used copper tape ($5 from a hobby store, look in the jewelry section) for the contacts, then lined them up with the contacts from the Palm Pre coil by putting the stock cover with the coil onto the separated plastic from the phone and lining them up by looking at them together.
Yes, this mod is not easy, and it voids warranties, but it is magic every time you stick your phone on a touchstone and it just starts charging. I bought a touchstone for my car, and then one for my nightstand. For <$20, I have a car charger and a home charger and it's super easy to just put the phone near the touchstone and let the built-in magnets hook it up.
Things to be careful of:
Do not short anything. Make sure not to short VCC to ground on the USB connector
Do not flip the power connections. Make sure not to tie VCC on the inductor coil to ground in the phone and visa versa.
Don't damage the resistor when you solder to it. Be fast. But get a good connection too
I used a multimeter to check for shorts and to make sure that I got VCC -> VCC, GND -> GND.
Very nice, only problem I see is you should of posted to the accessories forum. But overall a very nice mod and the directions were clear.

Nice mod! Thanks for posting it up. What's the difference in charging time compared to charging via USB?
Sweet, the TouchStone has been one of my favorite features with my TouchPad. I saw lots of people doing this with the Galaxy Nexus, but I wasn't sure if it would work with the i777. I know what I'll be doing with my next Amazon gift card.

Now THIS is the kind of inductive charging mod I wanted to see!
Saving the pics for later, just in case.
I see that you have a case on your S2 in the first picture, does the inductive charging work through cases?
Hasn't this been done on the sgsiiet?

I haven't timed it, but it's not significantly slower. I'm not sure what the difference is, though, because I just stick it on the charger when I go to bed and wake up and it's charged. But when I was testing it, it seemed to charge at a rate slightly slower than the USB charger.

You, my friend, have incredibly sharp eyes. I'm using a bumper case - so there's no backing to it. I don't know how well the system would work with a real case, but I'd assume you'd lose some charging current/efficiency by increasing the gap.

Yes, but not as far as I know on an i777 and the internal routing is a bit different from SGS2 model to model.
This is a cool idea. Maybe make a side job out of it for those that don't have the patience or time to do it? I work in electronics for the semiconductor industry so I have the hardware skills but between life and work i don't know if/when i will find time to get around to doing it. Just wanted to suggest it to ya since it is a really cool idea. Thanks for sharing it.

Nice. Would you be willing to post some higher res pictures showing the contact placement and the inductive coil installed on the back panel?
Also, were the inductive coil contacts labeled, or did you have to figure out which one was VCC and which was ground?
I've been meaning to attempt this mod after I saw a Galaxy S video showing it.
Can I get a picture of the back of the phone after everything is complete? Without the case, ofc.

I can do ones of the inductive coil, but I'm not going to take the phone apart again... I should have taken better phones when I had it apart last night... but every time I need to put it back together, it takes a while. I think what we have will have to serve.
There's only one resistor near the USB connector so even though the photo is a bit blurry, if you take the phone apart, you'll see right away which one it is. There's not much there... just a capacitor (the yellow thing) a small IC (the black thing) and then the surface mount resistor (the orange thing in the photo).
As far as the coil, I just peeled it off of the Palm Pre kit and stuck it on the case of the i777. The only thing was lining up the contacts so that they matched the places that I put the copper tape. For that I used to back plastic that was off the phone, that the back cover would attach to, attached it as if the phone was together, and then eyeballed it from the other side.
Also, were the inductive coil contacts labeled, or did you have to figure out which one was VCC and which was ground?

I used a multimeter to check. But the contact farthest from the coil is 5V, and the other, the inside one closer to the coil, is GND.

It looks like this:
It might look like the wire would interfere with a real SIM (instead of the microSIM that I have in there now) but it doesn't. Last week I was in Costa Rica and I had an ICE full SIM card in there and it worked fine. The wire doesn't push into the SIM card slot as much as it looks... or rather, you can tuck it under the plastic so that it's more out of the way.
Very snazzy. Got my parts in and going to complete this evening.
Stupid radio shack didn't have any copper tape tho...I'm going to try using the wire ends strategically placed and/or taped to get the same effect.

I tried it last night, but it didn't work for me. I'm trying to find out what I did wrong. I solder a wire to the resistor and to the touchstone cover directly to test. Then I wrapped the ground cable around a screw and screwed it down. The tester displays that the cables are receiving all 5 volts.
Mine seems to be a different model because that "U" that is next to the resistor in the picture appears to be on top of my resistor.
I'll keep trying to see if I can get it.

Cool. Congrats.
Mine is still working great too.
For the copper tape, I should have elaborated on that. I bought it at Michael's (a hobby/craft store). I think hobby stores that have supplies for making jewelry have it. I tried Radio Shack as well and they had no idea what I was talking about. Amazon has it too. But I think the cheapest option is a place like Hobby Lobby or Michaels or any other jewelry or stained glass window supply.
I tried aluminum tape - from Home Depot - but I had a really hard time soldering to it without soldering through it. Someone at work recommended copper tape instead.
Also, someone on another forum (I'm the moderator of the mobile devices forum at Anandtech) mentioned that their back cover has been popping off. This hasn't been a problem that I've had much - very rarely a corner will pop off after a day in my pocket, but otherwise everything fits pretty well. If people have problems with that, one could move the coil further down on the back cover and that should solve it. Or else you could use double-sided permanent tape from an office supply store and apply it to the inside cover where the cover is coming off.
I just picked up the parts to do this. $3 each for kits with charger and back from Amazon, so I picked up three. I have a couple of batteries that charge off USB that this could work for as well.
Test fit inside my otterbox commuter case seems ok, but will need more metal for the magnets in the charger to hang onto.

Sorry to bump an old thread, but this is an awesome mod.
@pfmahoney (or anybody else who has done this) have there been any adverse effects over time? I've read that on some other phones, you can't use the touchscreen while connected to the Touchstone. Is that the case on our model? I've also heard about overheating issues and compass issues. These reports were on other phones, though. Any thoughts?

Yes, you are right, you can't use the touchscreen while it's charging... well, actually, you can... just not the spot right in the middle. There's a circle about the size of the inductive coil that doesn't respond to input or responds erratically.
I haven't had any issues over time. I put it on the charger every night and it's been fine.
It does get a little warm, but not what I would consider excessively hot. I've had it get hotter playing games than it does on the inductive charger, but it definitely does warm up.
I have never noticed any issues with the compass - by issues, you mean the compass not working? I have never noticed that. I just tried the compass now and it seems to work fine... are these issues with the compass while it's charging? I've never tried that and I can imagine that there might be problems using the compass while it's charging inductively. If you need the compass while it's charging (for example in the car), you can always just plug it in to the USB plug - the inductive mod doesn't stop the regular USB plug from working.
Curious if anyone is using the Palm Touchstone wireless charging mod for the SGS3. I got everything for a Palm Pre, touchstone, cable, etc.. Did the mod which was stupid easy... but the buldge of the back cover is driving me nuts. I have no idea how to make it more flush again. There is ZERO chance of putting an case on here now, for 1 it seems like the charging signal wouldn't be strong enough... and the buldge would absolutely prevent it.
Any help would be appreciated.
BTW: I used super thin 24 gauge wire out of a cable (like a usb cable/printer cable) to go from the palm pre charging pads to the pins of the sgs3.
I used the palm pixi's back for my mid. It is thinner that the pre's so there is less bulge.
Edit: I also used copper foil/tape to make my connections. I don't know if that would reduce bulge or not though.

I read somewhere the pixi back was thinner but I read that after I ordered the pre back. I didn't have any copper foil tape so I used wire from a usb cable, and if I did use foil tape it seems like I would need something to push down into the phone connectors as they seem a tiny bit recessed.
Don't get me wrong, everything works, and charging works, but the bulge is noticeable and there is no way I could use a case back now. Glad I got the whole body Zagg invisible shield. :thumbup:
How did you address the phone connectors being deep inside? What did you use to make your foil tape touch the leads in the phone? I just kind of pushed the wires in there and used a little rape to prevent shorts.

On the Sprint model there is no sim card. If you cut a square out of the internal cover to the right of the microSD card you have a nice little space to hide the circuit board that causes the buldge. I just posted a question- where to buy the internal plastic cover? I don't want to risk screwing up my original.. BTW I used copper tape. On the pixie back I soldered the tape to the leads. For the phone connection I cut the tape too long and rolled it up to the spot it needed to be to make contact with the S3 contacts.
I have the touchstone and palm charging back. Is it possible to do this mod without soldiering the GS3?
Roll the tape up...:fingers-crossed: Sometimes I hate myself, I always think of the hardest way to do something.... Of course - why not roll the tape into a little ball. DUH!
I think I could probably get the bulge down a little, but I'm not sure it would make a lot of difference... I guess I could always just buy a pixi back and try again? or just wait for Sept and get the samsung kit.
I had read that the samsung kit will charge when the phone is relatively close by - I read 2 meters, but that doesnt sound right - that would be like 6ft... I would settle for 1 ft. The touchstone has to be RIGHT on it... If I had an otterbox case, I am 99% sure the magnetics wouldn't catch and I doubt think the charging field would work, because I can hold it just above the reach of the magnets and no charge. Touch it to the touchstone and BINGO.
I got tired of taking off my case every time i charge my phone,.... so i did alil bit of modification and i thought I'd share with you guys and maybe find it helpful,...
ok,... the case that i have is a Ringke FUSION Xperia Z2 Bumper Case,... i also have a Spigen Ultra Fit which like a lot,... but I've been using the Ringke FUSION coz i think it has the best protection all around,....
your going to need a Dremel for this modification or something similar
1.) your going to need to open the Sony DK36 Magnetic Charging Dock (don't forget to remove the adapters that goes into the charging port slot),... once it's open,... your going to want to raise the magnetic port so it can reach the cellphones port when you have the case / bumper case on,.... i used a 3M double sided tape (which is 1.90mm thick) so the magnetic port can be raised permanently (as you on the picture) (and don't forget to remove the USB cable while working on it)
2.) this is where you need the Dremel or something similar,..... make your marking on your case on where your going to cut out the hole,..... i used the Dremel with a grinding tool with a small tip,.... remember to start small and slowly make your way out (don't forget to remove the phone off the case when you start griding / cut),.... use the magnetic charging port as reference to how much you should grind out / cut out,.... every now and then test fit the case to the magnetic port charger,....
3.) by now,.... your magnetic charging dock should be closed and back together,..... your not going to need any of the adapters anymore,.... try testing the phone with the case to the magnetic charging dock,.... it should fit and charge your phone already,... if not,... grind alil bit more on case so that it clears the charging port completely,..... if that still doesn't work,... you may need to open the DK36 Magnetic Charging Dock again and raise the port alil bit more,....
4.) this part is optional,.... but i did this mod to give the phone more back support,.... i found a old CD case that i wasn't using and cut out a small piece,.. about the same size as the back panel,... grind the plastic until it fits on the back panel just right,.... i used a 3M painters tape to keep the plastic piece attached to the dock,.... (the 3M double sided tape was to thick and wouldn't allow the charging port the join,.... thats why i used a thinner tape on the back of the small plastic piece,.... just roll the tape together to make it a double sided tape)
(you'll see on the picture how the small plastic piece looks like with the charging dock)
Opening the dock
How can we open the dock? It's made of so premium plastic that I am not able to open it. Can you please post a video on how to open the dock? I have a flip cover which just uses the magnet to stick but does not charge because the golden pins are not able touch each other. Just write a proper step by step on how to open it or post a video.
sorry about that,... but its kinda late for me to do a video on how to do this mod since I've already done it,...
but i can still help you,...
i kinda had a hard time opening the dock to,... and learned my lesson,... so here's what you gotta do,...
on the bottom dock,... you would see a grip tape around the surface of the dock (it helps keep the dock from moving around the table)
there are 2 screws holding the dock together,.... and they are located on the side where the grip tape is at,..... so its actually covered underneath the grip tape (the middle section of the side grip tape) just remove a small portion of the grip tape so the screws can be revealed,.....and just remove it with a small screwdriver,.... (use the first picture that i posted as reference to get an idea on where the screw mount is at)
i hope that helps,....
SCR10 official case
I have bought my SCR10 official case, from ebay this seller: http://stores.ebay.co.uk/London-Magic-Store
You can use magnetic dock with it
It seems totally legit to me, I've made a small review, check it out.http://www.4gnews.pt/sony-xperia-z2-flip-case-scr10-review/
Really awesome and quiet cheap flip-case.
Tell me what you think
yeah i saw that case,.... i was thinking about getting it but i didn't really want a flip cover case,... while it gives you protection on the LCD screen,... it also has some down side like holding it up like a book when taking a picture,...

You are the best. After reading and following your instructions million a times finally I could achieve what I desired. I just made a few arrangements from my side as my cover is the ultra slim 0.3 mm which required only a small amount of tweaking.
You can see in the pic below that I used the plastic in both the ends with double sided tape because the Z2 used slip out of the dock sometimes.
Again a very big thank you for solving this issue for me.i was a bit afraid that what would happen if my charging flap came out. But you solved it for me. Keep up the good work
I´ve this case http://www.ebay.com/itm/11135176963...eName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 and fit to dock very well.
First let me apologize about the quality of the photos. I did the mod at around 3am in the morning and the lighting was lousy. Anyway, after months of searching for a good but relatively cheap QI solution for the G2 F320L, I decided to go ahead and mod it instead. It works great so far so I'm posting basic instructions and some pics so others can do the same and also learn from my mistakes in the process. Essentially what I did was connect the middle 2 pins of the extra 4 pins to a QI receiver coil mounted on the outer side of the phone's back cover. I don't know the actual polarity of the pins since I just did some trial and error with the QI coil and the 4 pins to figure out the correct ones. Oh and yes, I did a sucky job with the mod. Fortunately, none of it is visible once everything is in place.
Here's what you need:
1. 3rd party internal QI receiver coil - I used one that was designed for the Samsung Galaxy S3. You may be able to get more flexibility in positioning the receiver by getting one with a relatively long ribbon cable leading to the contacts instead. Also if the contacts area are as thin as the ribbon cable, you may get a neater result.
2. A working QI charger that has charging indicator LEDs - duh. But seriously, there's a number of things you may want to test before you start doing the mod and you want the indicator LEDs to tell you whether you're charging or not.
3. An extra back cover - I actually used the original back cover that came with the phone as it had physical damage already, but I recommend you get a cheaper third party back cover instead, just in case.
4. A two layer case with a soft inner layer and a not-so-thick, non-transparent outer layer - I used a Spigen Slim Armor case and it works marvelously. I have a Ballistic Shell case somewhere but since I can't find it at the moment, I can't check if it will work, but I do expect it will work too. (EDIT: I found my Ballistic Shell case, the mod will work with it and I'm considering modding it soon) Also, your QI charger will also determine whether or not the case of your choice works. Particularly, the charger's plastic cover on the charging surface combined with your chosen case's outer layer should be thin enough to still let you charge wirelessly. If the distance between the actual charger coil and receiver coil is too far, you won't be able to charge properly.
5. A small, sharp knife that can cut through the extra back cover and your chosen case's inner soft layer cleanly - I used one, but I just suck at cutting stuff.
6. A roll of thin double sided tape, and preferrably, also a roll of thick double sided tape - My receiver coil already had a thin strip of double sided tape so I ended up not needing anymore, but you might, even if your receiver coil has a strip of double sided tape too.
Ok, first thing you do is test, test, test. As far as I know, the extra 4 pins also exist on other F320 variants and that the QI pins are also there. Since I only have an F320L, I can't be sure for certain. Also, it's very unlikely, but it's possible that there are different F320L revisions with actual changes in wiring those 4 extra pins. So test everything before you start the modding. Do test your case's outer layer by putting it on the charging surface and putting the coil on the case, the outer layer that is, while it's on the QI charger. Chargers will detect if your a receiver coil is present but they can't detect if your coil is actually connected to something so you don't have to actually connect it to your phone yet. Don't keep the coil on the charging surface for more than a few seconds when it isn't connected though. Once the charger detects the receiver coil, it will start sending charge to the receiver and if the receiver can't send that charge elsewhere, it will just accumulate on the receiver's electronics which will cause it to overheat and eventually burn out. Once you're confident that everything works, then you can start the mutila- err cutting.
First thing you want to do is to cut a hole on the extra back cover such that you can make the receivers contacts connect with the QI pins on the phone without having to put the rest of the receiver inside the back cover. The receiver will be taped to the outside the back cover. If your receiver has a thin ribbon cable and with exposed copper surfaces an the end to serve as contacts, you can cut a small slit into the case that will let you insert the ribbon cable through. If you have the ribbon cable but with thick contacts, you'll need a bigger hole. If, like me, you only have a stub sticking out from the side of the receiver coil containing thick contacts, you will need a hole that exposes the QI pins on the phone. Before you start making the hole, make sure you plan on the actual position you will tape the receiver in so you can make as small a hole as possible. As you'll see on the photos, I didn't exactly plan it right.

Once you're done with the back cover and installed it along with the receiver coil onto your phone, get your QI charger again and test your handiwork. Make sure the phone actually detects that you're charging. I was being a retard and proceeded along without testing at this point. :silly: Don't make the same mistake. Also, take note that I put a rubber tape shim on top of the receiver's contacts. This is because I have to push it down for the contacts to connect with the QI pins. It might not be necessary in your case, or it might. Do whatever you need to to make sure that the connection is secure. You don't want your receiver coil to burn out because the connection went lose while you were charging your phone at night when you're asleep.
Now, it looks rather ugly doesn't it? Well, that's where the two layer case comes in. If you just put the case on your phone right now though, you'll probably have a bulge on it where the receiver is. For the Spigen Slim Armor, you won't even be able to fit the outer layer properly. So go ahead and cut a hole on the inner layer to make room for your receiver. You should already be sure of your QI coil's positioning at this point so you can should cut a hole in the inner layer as precisely as you can. Here's a photo of my lousy worksmanship:
If you want to know how it looks like with the case's inner layer installed with the outer layer, use your imagination. What? Do you expect me to do everything for you? (Actually, I'm sorry. I forgot to take a photo. This is what happens if you do things at 3am in the morning. )
When you're done cutting a hole on your case's inner layer, go ahead and put the case on and test it out again. If that works, then you're now a proud owner of an LG G2 F320* with QI charging. :victory:
If it doesn't work, it's very likely that your case's outer layer is just too thick and you didn't test it beforehand. Good job. :good: Well, that, or your case's inner layer is so thick. If that's the case, you can remedy the problem by putting additional layers of double sided tape underneath the receiver coil to bring it closer to the charger's coil when charging. Ideally, the receiver coil's surface should be flush with your case's inner layer when installed. See end results below:
(yeah, this is an old battered case, but the nice thing about this particular one is that I can buy a new one and use the outer layer with my modded inner layer)
NOTES:
Your ROM might not be able to detect wireless charging, in which case, it will say you're charging via USB instead. In fact, unless you're using a ROM based on the G3's ROM, your ROM will probably not be able to differentiate between USB and wireless charging. I don't know if Tasker will be able to differentiate either. I'll make sure to post results of whatever I test.
The mod is sort of non-permanent. You can install an unmodded back cover (you didn't use the original one for the mod did you?) and nobody will be the wiser.
Repairs are easy with this mod. If you choose a receiver coil that's readily available in your area, if your receiver breaks, you can just remove it and replace it with the exact same receiver with very little fuss.
If you do the mod correctly, you can remove the back cover at will without fear of things falling apart. If you didn't do it correctly, well, too bad.
If you do the mod correctly, you can transfer the mod onto any other F320* if the QI pins are also in the same location. If you're an enterprising individual and can do the mod very cleanly, you can even sell your work. But please send me some Guinness if you do.
If you didn't sell your work but find this useful, feel free to send me some Guinness anyway.
If you didn't find this useful, eh, I'll still accept free Guinness.
So... Why not trying to fit one of those chinese QI wireless receiver modules inside? They look thinner. And after dissasembly one of them, maybe you'll get the same functionality as the one in the pics. Do you think it could fit inside?

The thinnest ones I could find definitely do not fit inside without causing a very noticeable bulge on the back cover. Even a microSD card causes a noticeable bulge, so there's very little room between the back cover and the battery. An additional problem is that the NFC coil on the back cover will likely interfere with wireless charging. NFC works fine with the wireless charging coil on top of it.
Why didn't all g2's come with those pins...
Im thinking of trying this mod but keeping everything behind the cover, gonna get one of those chinese receiver pad's and run some thin wires to the 5v and ground on the usb connector... this should work right?
The other options is getting the verizon usb flex cable which seems identical to the d803 cable, even the connector near what i believe is the digitizer is the same size.
Has anyone tried this before?

I expect it will work. I've seen a similar mod done to a OnePlus One. There's a couple of caveats though. For obvious reasons, Android will not be able to detect that you're using wireless charging and will assume that you're using a wire to charge. The 2nd caveat is that you cannot charge while you have a USB OTG device plugged in. You may be able to power the USB OTG device via the QI coil. That's normally a good thing, however, if your coil delivers too much current, something (the coil's electronics or the USB OTG device) will likely overheat and burn out if used long enough.
EDIT: I forgot to add that the NFC coil on the back cover will make it harder for you to get this to work, but it is possible. I've found though that certain coils just don't work unless the NFC coil is not in between the QI coil and the charger. It may be a charger related problem as well. You will need to find a coil and charger that will work despite the NFC coil being in between. Or you can just remove the NFC coil.
@jaybz
Hey I tried the same thing you did with everything you provided but its not working... The wireless pad lights up as charging but nothing indicating on the phone that its charging. Is there something Im missing?
Thank you

It likely means that either your wireless charging coil is connected to the wrong pins, or they're not connected at all. Also make sure you're using a coil for the Galaxy S3 as those for other phones may have their polarity reversed.

I tested the pins with the multimeter for 5volts and ground and its making contact...
Ugh lol

You sure it's the correct pins then? The ones you want are the middle 2 pins on that group of 4.

Yes the middle 2. The top pin of the middle 2 is 5volts and the bottom of the middle two is ground.

Aside from a broken charging coil, or shorts somewhere, the only thing I can think of is that those 2 pins are not actually connected to the charging circuit on your phone like it is on mine.

Well I did just flash the lollipop update 2 days before I did this. Could that be a issue. I heard that lollipop has a bug for some qi devices...

I suppose that's possible but I'm afraid I can't verify that myself since my G2's screen is broken.
Discovered my back cover is bent after taking my phone case off. tried to bend it back but now there are gaps where the buttons are. Still works fine I am just looking for a replacement back cover.
Any recommendations? I've looked on aliexpress not sure which ones are good or not, and some comes with "fingreprint flex cable" and "Sim card holder" they look dodge as, not sure if its meant to be inside the cover or outside. . . . regardless do i need one with fingerprint flex cable? is this somehow attached to the external covers?
Covers i am looking at https://www.aliexpress.com/item/for-Xiaomi-Redmi-Note-4-Global-Battery-Back-Cover-Rear-Back-Door-Housing-Card-Tray-Holder/32905160801.html?spm=2114.search0104.3.10.3749fb1ar1oAVk&ws_ab_test=searchweb0_0,searchweb201602_4_10065_10068_10130_10547_319_317_10548_10696_453_10084_454_10083_10618_10307_537_536_10131_10132_10902_10133_10059_10884_10887_321_322_10103,searchweb201603_70,ppcSwitch_0&algo_expid=f3ba9a01-2a7e-4b0f-ae21-4f6e684df1cc-1&algo_pvid=f3ba9a01-2a7e-4b0f-ae21-4f6e684df1cc
If anyone knows where i can get genuine covers would be great as well.
