What are the four pins under thr camera for? - Thunderbolt Q&A, Help & Troubleshooting

I just noticed these four contact pins directly under the camera. Are they for the inductive charging battery door?

Rumor is either the inductive battery door or a future NFC battery door.

Considering the antenna is integrated into the back cover, I would assume it is for that. However, I could very well be wrong, as I do not have a Thunderbolt to check it out.

There are two pins separately connecting to the battery cover for antenna. And another 4 that connect to nothing right now.

Hoping it's inductive, could care less about NFC, personally.

Yeah every review I saw that commented on it seemed to hint at the NFC concept too. I agree, though its a neat technology, I don't really think that NFC is something I'd want to deal with as well credit cards w/ similar technology make it easier for people to steal your number... just adds another potential security issue w/ phones. Of course that technically is a good thing for me as that's sorta what I'm researching currently.

I think it is inductive battery door... because there were product leaks that hinted at this!

That is probably right, as I have seen the inductive battery door listed on quite a few places, but wasn't sure if that would have some other way to transfer the energy. But I saw that mentioned on articles along with discussions of the extended battery, which you can get currently. But I've seen prototypes for the induction charger to go w/ the door... so yeah that makes the most sense, but not sure why it'd need 4 pins??

Well I did a little experiment and the far right battery pin is connected to those four pins. So it looks like it is for the inductive battery door.

Inductive Battery Cover??? How have they not mentioned this before. That is really sweet if it works. Now what power mat will it work with?

I believe that means your battery is overheating. I think it happened to me on my og EVO once. I set my phone down turned it off came back later and it was all better!
Sent from my PG86100 using xda premium
Yeah..pretty common with some evo3d's..the battery isnt making good contact on the points..just put a little piece of cardboard or something between battery and the inner rim of the phone to help push the battery into the gold points of the phone..I had this problem and never seen it again after doing this.

LMAO go talk to Sprint and get a new phone. These so called "fixes" are the reason why manufacturers don't give a **** about quality products anymore, too many people settle with broken ****.
Oh and by the way, let's say his battery is overheating and he takes your advice; cardboard/paper catches fire... And he now has no phone.

pretty sure he can tell if his phone is over heating if he really wanted to..the cardboard is no where near where the battery connects to the points.So if it magically catches fire then I guess you would be right..As for the manufactures not caring about quality control sure I get your point.But thats not the point of the thread.He asked why its happining and there are only 2 ways it has ever happend to me.Over heating and/or battery not making good contact..Just offered a simple "fix" for the moment.If it doesn't fly with him then he can go waste his time getting a replacement that may very well do the same thing.
What kernel are you using? That can have an affect on it too

According to another thread, this phenomenon is known as "randomly sausage". (I really hope I'm not the only one that understands this)
Hello,
Of a similar bent, multiple times since I had a Refurbished 3D sent to me, the Battery has drained to zero whilst being plugged in to the Charger. This has primarily occurred when plugged into the Wall as opposed to say my Laptop. It happened again this Morning.
When I insert a different Battery, it seems to fix the problem and the 3D Charges as usual. However, this is one damn annoying issue.
Cheers,
JJ

What are the two holes on the back of the phone?

To the left of the speaker grill. Can't figure it out for the life of me. It has contacts so it has to be something.

External mic for speaker mode, when you flip the phone over? Completely random guess.
pretty sure I read a review that said the rezound has 2 noise cancelling mics.
Those holes are for the antennae. The noise cancelling mic looks like it's on the side. The thunderbolt had similar holes.
I asked the guy at the Verizon store and he said it has to do with wireless charging but that didn't make sense to me since it has contacts and wireless charging requires a different back cover.
I did notice some cases have a cutout for them and some don't.
There's no mention of them in the user manual.
Yeah. That is the main reason I would like to know. My case doesn't have the cut outs and I don't want to cover them if they were mics.
Surely there wouldn't be microphones built into the battery cover though.

pinholes for a dock station

Not mics, not for wireless charging, not for a dock.
HTC CS said:
If you remove the battery cover, you should see that there are copper contacts on the inside of the cover, and that the holes in question are the mounting points of those contacts to the battery cover. To my knowledge this is the only function these pin holes provide, and I see no way for covering these would have a negative impact on the device.

I'm getting a chuckle at some of the responses. Not sure if serious, though!
The five sets of contacts on the battery door are all antennae for the various radios. CDMA, Bluetooth, Wifi, LTE, GPS.

Holy test points!
I can only imagine that the holes that lead into the CDMA antenna contacts are for test points, as there is probably little reception inside the factory and an auxiliary antenna might be used to obtain a signal. OEM accessory covers, like the wireless charging and extended battery covers, do not have these holes, nor would they be needed since they are not supplied with the base unit.

kickstand complaint

After having my Photon for four days I have been loving it, but have one complaint regarding the kickstand.
If you have the kickstand employed, you can not plug in a charger. I was trying to watch a movie during my lunch break yesterday and the battery was dying, but I could not plug it in.

actually its a good thing its main kickstand side is on that side cause no buttons can be accisentally pressed(ive been charging and using the kickstand like so, was resting my hand ontop the phone reading and it hit the camera button exiting my window) so maybe in the future theyll come out with some alround better design for a kickstand and plugin/button placement

Maybe two centered kickstands that can rest and be locked either way. With a slant we could also do this vertically.

My favorite thing about the OG Evo right there.. bottom usb port.. made life so easy
Actually the port placement is terrible for the Photon/Electrify. Consider the car. You're driving, and you have your phone in a holster within reach of the driver. In America, where this phone is primarily sold, the driver sits in the left seat, so the phone is to his/her right, probably on the left side of the instrument panel. Probably, the 12V outlet is somewhere to the right of that, so the charging cable has to reach around. Mine isn't quite long enough, so it threatens to pull the phone out of its holster. This is unsafe for driving. With the port on the bottom, it would be convenient for drivers on both sides (e.g. UK for the right) as long as your holster has an open bottom (mine does).
Actually, my Electrify does the Hero S (Evo Design 4G, for you Sprint folks), which I had for 6 days, one better. Hero S also had it on the left, but right where the holster grabs the phone. So using the holster was impossible with that phone. Just one of the reasons I traded up to Electrify.
Back to topic: Reverse kickstand is cool, but it depends on the spring action being intact. I'm not sure if it can go out on you, but that would kill reverse kickstand if true. As it is, having the charger cable coming out the "top" can pull it back if the cable doesn't have enough slack.
If you want normal kickstand, I recommend rigging a stand, like a poor man's HD dock. Put a hole where the USB port goes, and if you really wanna be fancy, fix it in there permanently. But if you were gonna be fancy, you'd give it a backing (with a space for the speaker, of course) but all that implies you're better at woodworking than most people. I'd like to think with the right hardware I could do alright, but I know my zero woodworking experience means I would utterly fail to produce anything approaching reasonable quality.

Why put the micro USB port on the side?

Hey Guys,
Don't you guys think the USB port could have been placed on a better spot ? Maybe where the old evo had it or on the right side.
How are we support to charge our phone while using the kickstand Horizontally.

IIRC, the motherboard is limited to the top of the phone, so it would require additional wiring/circuitry/supports to have a jack at the bottom. I do agree, having it on the side is asinine. Hard to talk on it when plugged in too.

Until that hinge wears, loosens, and no longer holds the phone up
Its not a deal breaker. But this phone would be perfect if it had a bottom charger and removable battery.
I use the horizontal charging all the time at work. The cord sticking out the top looks stupid. So if you have it plugged in to a radio you have a cord sticking out two sides.
I would guess that it's so you can use a landscape dock with a charging port.

Probably has more to do with a space issue caused by the non-removable battery. The port could go anywhere on the phone and they could just run wires back to the USB/MHL header on the circuit board, but the port has to fit somewhere.

review of $14.89 Twin USB Cradle with 2nd Battery Slot for Samsung Galaxy Note

hi all, i just received this docking station from tmart.com for under 15 dollars.
i have a extended battery i reviewed from them and it was so good that i decided to review this item.
here is a link to the docking station
http://www.tmart.com/Twin-USB-Cradl...te-i9220-n7000-Black-Only-Cradle_p140022.html .
well first impressions is it is a good dock it has dual usb ports, you can plug your wall charger in to it and also plug it in to your computer at the same time which is a nice feature.
when charging your phone it stands straight up but you can lay it on its side for movie watching game playing just not charging.
pretty sturdy plastic and has a led that is red and turns blue when the spare battery is charged.
i have a few battery's and the extra charge bay is great.
here is a few pictures of the dock.

it does charge the battery pretty fast
well as of last night it topped of my 3250mah mt stock and my 5200mah battery's and has my sons galaxy blaze charging on it to.
i like this dock and it is very useful for media viewing or playing games with my wii mote
So I'm guessing this doesn't work with the Tmart extended battery cover, eh?
No it don't, what I will he doing after I test out my 3250mah battery is rotate so when my 5200 dies I can pit it in the charging slot and run my 3250 while that's charging or my OEM one.
I like the dock though it comes in pretty handy.
