inductive charging?

anybody know what the pins on the back of the battery cover are for? it looks like what you would find on a phone capable of inductive charging. if so, anybody figure out how to do it?

They act as an antenna, dont **** with them

hmm ok. ill have to try it with the cover off to see its actually the antenna but ill take your word for now.

it does when i was playing with my phone without the backcase on i had no service

I only get 2G service when the back cover is off. I think it has something to do with the antenna as well.

I actually was wondering what the pins were for. I just took my back cover off and immediately dropped all signal.

thats kinda weird to have an antenna in the back cover. maybe they plan to release a new back cover that will improve strength? i cant seem to understand why.

Its just the design. And it saves space on the device.

Its definitely the antenna... and i personally think it was a brilliant design!

inductive charging would be great for our phones, i know the palms do it!

So anyone want to do the palm pre inductive charging hack. I think it has been done on a hd2

HTC states that the battery cover of the aria is the antenna on their website under troubleshooting:
My device shows “No Service” but I know that there is coverage at my location. close
The antenna for this device is embedded in the battery cover. If the battery cover is not installed correctly, securely affixed, or if it has been damaged, this could be the cause of the device not picking up on a signal.

None to low wifi reception after housing change .

Hi!
I changed my housing and now i barely have a connection to my wifi. I dont even have a full reception when i hold the phone next to the router. What can i do? Any tricks to make it better?
Thanks for help and excuse my english.

Housing where you live or phone housing?
If it's phone housing then you've done something wrong mate.

Yea the phone housing.
Any idea what to do? I dont know where the wifi antenna is.

I have no idea mate. A friend had a similar issue, he ended up just taking it to a repair centre, but he had actually caused damage.

Did you find this thread:
http://forum.xda-developers.com/showthread.php?p=16143004#post16143004
ans specifically post 34, it contains a link to download full (official) disassembly guide and parts list.
I replaced my middle frame awhile ago cuz it was damaged and remember there was a sticky piece on it called something like ANT/GPS flex, might just be for GPS but could easily also be an antenna/amplifier for more wireless signals.
Usually the wifi chip itself is on the motherboard, but i didn't have to disassemble that far for the middle frame.
You could open up your device and see if you have replaced that 'flex thingy' correctly.
Hope it works out for you!

Gps problem?

Hi all.
Recently I went to use my gps and it detected me around 200-500m off from where I was at. I refreshed it and problem still exists. Feel like uninstalling gps, but how? Any ideas/solutions? Thanks in advance.

What rom are you running? dont know what to say, i run stock with 2.3 and the gps has always been spot on so my guess its the rom thats probably not the best cause the desire gps is known to be very good.

Thanks for quick reply. Followed the guide, problem still exists. Any other options/fixes?

My (wife's) Desire developed a GPS problem as well. Eventually I had to disassemble the phone and bend the antenna contacts a little bit to fix the problem.

So there is no other solution?

In my case, no. The problem was not software or faulty hardware, but GPS antenna contacts that came loose (probably caused by dropping the phone).
I just posted this under another thread, but here goes again (this was a while ago and I can't recall exactly where all the contacts were that I bent slightly). If your phone is no longer under warranty it is a worthwhile procedure; it will save hundreds of dollars/euros if you can fix it this way. In my case the GPS eventually stopped working altogether - it would never see any satellites under GPS Status, never mind lock on.
I fixed it by opening up the phone and making sure all GPS connections were good. If you are reasonably handy you can follow these instructions to dismantle the phone:
http://www.youtube.com/watch?v=sXZqIjtFoAU
The GPS antenna is shown at 2:47 (it has a connector at both ends - make sure that both are snapped into place).
But before you disassemble the phone that far, at 1:49 in the video ("Remove the antenna") try the following: when you have removed the antenna you will see several copper contacts (similar to the two vibrator contacts highlighted in the attached photo). I seem to recall there were 4 copper contacts under that antenna cover. Gently bend the contacts slightly upwards - this will either ensure better contact or (as with my phone) re-establish contact. To remove the antenna is very quick.

Awesome guide. However, since I'm only 15 I don't think I can do it. The tools that are required are currently not available...
Sent from my HTC Desire using xda premium

It's not as complex as it seems - to remove the antenna you only need a Torx T5 screwdriver to remove the 2 screws. It will however void your warranty if you're still under warranty. In case it helps anyone else, you need 3 tools to disassemble the phone to the point where you can access the GPS antenna: a Torx T5 screwdriver, a small Phillips screwdriver (the type you get in cheap precision screwdriver sets) and a plastic guitar pick (to gently pry the phone apart starting at the indents provided in the phone's body).
Actually there are also contacts to be adjusted on either side of the camera, accessible at 2:11 in the disassembly video (and not only under the antenna at 1:49 in the video). These screenshots shows all the contacts I adjusted (in addition to the GPS antenna).

Touch screen problem

Just recently acquired a g2.
Im having a problem with the screen where after revealing keyboard and then closing the screen jumps back after scrolling.
I don't know if it is something with using custom ROMs on the phone or could be the ribbon cable going bad.
Seems to happen worse and better depending on the ROM.
CM7 was almost impossible to use the screen without everything being long press with only a tap
Sent from my HTC myTouch 4g using xda app-developers app

Found the problem in case anyone finds something similar:
The ribbon cable had a spot worn out from opening and closing keyboard over the years. So I guess it was grounding out on the base of the phone causing the screen to act up when touching. In case u don't know that cable provides input and feedback to motherboard.
Solution:
Just took apart phone and removed motherboard to expose problem area. Cut a piece of electrical of standard width with about 4mm tall and covered area. Works perfect now.

[HELP] Poor reception after repair

So, A week ago, I broke my galaxy s4 successfuly damaging the LCD. No Big problem, Ordered a used LCD from e-bay and carefully took the old one off and installed this one. Boot up the phone and wallah! it works fine. EXCEPT! The stupid thing doesn't have reception half the time.
Sometimes its stuck on edge with full bars, sometimes its got 4gLTE but no bars, Sometimes its got a circle with a line through it saying no service and sometimes it has all bars and 4glte yet it still says searching...WEIRD.
So I tore apart the phone again up till the board and carefuly started inspecting everything , looked normal. Looked on the rear frame. A plastic piece where it says R1 was coming off, so I took it out completely and re-glued it back on. Turn the phone on and same thing. I did lose all the screws during the repair.... silly me lost the magnet they were stuck on and have not been able to find it. So unless the screws act as antennas which is possible, it is losing service all the time. I suspect the plastic piece where it says R1 is the problem and have ordered a new piece due to arrive on monday next week. The only problem is I just moved and am expecting quite a few calls for job interviews. Can't risk losing a great opportunity.PLEASE HELP ME WITH ANY ADVICE YOU CAN GIVE!!!! thanks!

If you're having issues with the reception I recommend having a look at the micro USB/charging board. I swapped that part out before after breaking it and had horrible reception. I then purchased another one (actually meant for my phone) and all was well again.
