Hi!
Can somebody pls explain to me which part of the touch cruise is the actual antenna responsible for gsm and gps reception? When dismantling the cruise, there is a thing called antenna-cover (where the camera lens and external gps-antenna plug are located). Underneath i find an orange thing. Is this supposed to be the antenna? If so, how is it conected to the board? Is it only the three pins on the board, touching the antenna?
I am asking, because my cruise got pinched at the top where the antenna should be located. After that i suddenly got bad gsm/gps reception. If this orange thing is the antenna, i doubt that it is damaged. The only explanation to me is that the connection antenna-board is disrupted.
Any suggestions are appreciated. Thanks!

Check the Polaris section in the XDA-Wiki for the service manual... maybe it will answer your HW related questions...
Hi
I recently did a rebuild on my one s to replace the vibrate motor/ribbon cable & also inadvertently resolved my touch buttons not working
Since then unless the phone is in a very strong signal area (we have a femto cell in the office which it connects to fine) it gets nothing at all - my sim works without issue in other phones so that's not it
I understand that the GSM antenna is in the lower section of the phone, I've checked all the gold contacts and the wire running down from the mainboard to this daughterboard, disassembled and rebuilt etc but the issue persists.
My question is, is it worth going through the radios and flashing to see if thats it - or could it be the replacement part was faulty?
Any advice or things to try would be appreciated
Cheers
Hi,
yesterday my brand new Photon Q arrived, which - after doing the SIM mod - hopefully will replace my Sony Xperia Pro.
While playing around with the Photon there was some thing that disappointed me a lot:
The sensitivity of WLAN is very poor. I own 6 android devices with WLAN, and the Photon has the poorest WLAN sensitivity of all.
Using it about 10 m away from my router, through a thin wall of bricks, it tells me connection rates of about 2 MBit only (varies from 1 - 5 MBit).
My Xperia Pro shows - at the same place - connection rates from 60 to 65 MBit!
What are your expierences with WLAN on your Photon Q devices - compared to other devices you own?
Thank you.
P.S.: 2 m away from the router the speed is 60-65 MBit too, so maybe I have an issue with the antenna of the photon Q?
Hi.
Although this is pretty old, I feel like answering to it, since there never has been any answer.
What was it, that caused your poor WLAN? I guess, the guys who do the SIM mod, when they cut the small gap the inner cover where you insert the SIM later, they sometimes damage the antenna in that spot, which may be the WLAN antenna. What do you think?
I have a SIM-modded PQ, but no problems with wi-fi.When I disaśembled PQ I haven't seen anything antenna-like (wires, fractal mazes) on the motherboard...
The back piece of the phone that holds the speaker and camera flash also contains the antennas. On the bottom there is a piece of black tape that I'm pretty sure covers one. Maybe this piece was damaged where an antenna is located?

That's correct. It holds all sorts of antennas, and on the back of the battery there must be the NFC antenna, right?
The seller, who modded the phone now told me, that at the bottm, where he made the SIM slot, there is the GSM antenna, not the WLAN one. So, today I'll get to open it and have a look, what else looks disordered. Maybe some plug on the mainboard or some of the antenna contact is bad. And just in case - I have one more cover from another PQ.
But if all this doesn't help - I'm grateful for more ideas
Yes, on the back of battery that's NFC antenna. Dismounting PQ is quite easy, but you have to have a T5 torx screwdriver.
I know how to unscrew the cover and even the mainboard of the PQ and I have precise tools.
Having done so and having replaced the cover with the slightly damaged antenna by another one where everything is intact - I experience the same weak WLAN It says 1 MBit/s in 2m distance or up to 20 MBit/s, when I am 10cm next to the access point. What else can be wrong or damaged?
If the cover is ok, maybe connectors to PCB are dirty/damaged (but you've probably already checked it). And how about another router? Maybe the one you're using is damaged or "doesn't like" PQ?
Thanks for the ideas, but from what I can see, they look good and clean and bent the right way to make safe contact And yes I tries other access points. I tried with my Droid4 providing a hotspot, my tablet, at my family's house, my girlfriend's, at work, at home... It's the same everywhere: very close or up to 3 meters, no obstacles, I have signal, but 1 or 6 MBit/s only, Further away or a door in between it's gone.
Can Android (CM 12.1 / 5.1.1) cause this, or must there be a hardware issue? How likely is it that these kind of problems are caused by a broken WLAN chip rather than an antenna problem?
I bought it in this condition from a guy who modded it (SIM mod)

Flash stock if you'd like to rule out issues with CM - although I doubt it, definitely sounds like a hardware issue.
I returned the phone to the seller, it was definitely something wrong with the hardware. I ordered a fully working board from another seller, since I still had a damaged Photon Q anyway, SIM modded it myselt and got everything working now, incl. GSM and WLAN. Thanks here.
Yo there folks, I have an important quick question!
Is OPO's daughterboard the hardware part responsible of cellular signal?
(Yeah I know about the antenna, but is it daughterboard or motherboard which doing the cellular job?)
I'm about to buy a new daughterboard cause after the screen replacement I did myself i no longer have cellular signal!
Please I need a respond to this fast!!

Hey mate, did you fixed your cellular signal changing the daughterboard? I have come accross the same problem. Would you mind sharing your findings, since nobody answered your question?
Thank you in advance.

The network antenna is connected to both daughter board and motherboard but I guess changing just the network antenna should do the work.

Thank you. I'm positive that the Motherboard is in mint condition. I have changed the antenna coaxial cable, the last resort is to change the daughter board. I'have just bought one from Aliexpress. Hoe I can bring back my beloved OPO alive.
Thank you for the tip.
Cheers from Brazil.
Hi,
my woman dropped here N5 (again), now theres no more cell mobile networks and GPS available,
means, no calls possible, no mobile network (exept wifi), no GPS.
is it possible that the antenna block (black bottom piece) is broken and a replacement could solve it ?
i teared the N5 down and checked all connectors, everything is looking fine. light grey and black antenna cable on the sides are properly sitting,
the black bottom antenna and speaker block is sitting, i dont see any destruction inside ...
is it possible that theres one chip broken wich rules the cell and gps function ? or may its really just the antenna in the bottom ?
if theres on chip i wouldnt need to look further anymore couldnt find the info about this ...
for an hint thanks ahead
Edit, can be closed, found the description and yes, Network IC is responsible for my Problem ...
