[Q] Antenna Mod - Xperia Play Q&A, Help & Troubleshooting

I'm thinking about trying to mod my xperia play's internal antenna since they decided not to include an external antenna port on the play. I need help identifying the internal 3g antenna I'm ok at soldering so i'm not to worried about that. Has anyone done this yet? I'm wondering if it is even worth it.
Any help or advice would be appreciated.

I remember people complaining about weak signal were talking about that - don't know what happened at the end - try searching weak signal posts.
Hope it helps

gsm/dcma signal dropped suddenly

I don't know what happened, but I have had the gio for a year and I've never gotten this kind of problem. I think it's not a rom related problem because I tried to stick a pin into the external antenna to boost the signal and I got it back immediately. Unfortunately there's no spare part of the antenna, so I should change the whole mainboard. Do you know where I can find it and whether it's worth the hassle?

Try flashing a new radio, and if that doesn't work, your gonna need to unroot and get it replaced by Sammy.

GPS dead?!? No GPS Signal

Hi,
EDIT: Fixed it by myself, resoldered the GPS Antenna 2 times, now it works
Can be deleted/closed.

Do you have any pics, tutorial ? or know a link. Just for knowledge sharing.
You can use FasterFix free app to choose your continent/region and get better GPS results

I used this one and some Pics of the Backcover to look where the contacts from GPS Antenna are.
now GPS Problems again :/
Replaced my LCD (was broken), all worked fine, but this week i needed GPS and i saw that it didn´t work.
I thaught ok, i already had contac Problems, so i soldered 2 wires to the GPS Antenna, but still no GPS Signal
Then i thought its Kernel related, so i reinstalled ROM (without Wipe) and the Stock Kernel. (ARHD 19.2) but still no GPS..
I deleted AGPS Data, no GPS also ((
Now i don´t know what to do, or test now :/
I measured the wires from One X Board to GPS Antenna, all ok, soldered good.
I have no idea what i can do now, but i want really a working GPS :crying:
no one has such silly problem like me???
How can i test if GPS works properly and its just a AGPS Problem?!?
How can i test GPS Antenna and the Hardware without getting a Sattelite??
The only thing i am sure is that the Antenna has contact to the Board, because i soldered 2 Wires in...
The antenna is is the same concact, so both wires are connected to the one contact antenna, right?
don´t know where the problem is
but im sick of searching, all things i thought could be didn´t help till now...
changed base, changed kernel, soldered wires directly to antenna and and and.. now i have no ideas
Even though you say you are sure you have soldered the wires in correctly, it sounds to me like a hardware issue as opposed to anything else. On my old hd2 my touchscreen broke and I sent it to a repair shop, had it fixed but then a week or so later had no gps, couldn't get it to work no matter what. My guess was that maybe one of the wires had been snipped when they had put the case back, I couldn't prove it without taking the back off, which I wasn't prepared to do. Can you not send it in for repair?
Sent from my HTC ONE X
if i send it to repair, they only can change motherboard or antenna, right? The price for this will be a new One X i think, so thats not rentable for me. But soldering something in and out should not be a problem for me, but i want to know whats not working, The Antenna i cant Mesure if it works correct or not, right?!? If its a Software Problem, i don´t know what i can do to solve it.
I tested, then after long time, GPS Test showed me 3 Satelites for 1 Second and then again nothing and nothing and nothing...
So what would be great, if i can look or do something to be sure its software or hardware related....
I even shortened all wires to let them very short, the are max. 3-4 cm long (Wifi. GPS, and 3G)
So i wired connectors top left, top right and middle down...
But on one side in near of NFC connectors (they are bigger) there are also 2 small connectors, for what are they? Should i wire them too??
Are there any things i can do, like delete some files or reset something, delete cache of definited apps or somewhate else? Reflash Rom with FULL Wipe, also didn´t work
AW: GPS dead?!? No GPS Signal
Is there any manual what connectors to check such are used for GPS? The 2 on the antenna I know, but perhaps there is a flat cable such is not connected good? And where can I buy a new antenna, I didn't find one yet.

Nobody knows?

yaaaaaaaaay, it finally works
after flashing to stock with full wipe, trying other kernel, other baseband, did different soldering tries (with cable, without cable) and nothing helped, i was shortly before to sell the one x (not really, but i was angry about it) and i tried lot of apps and gps.confs.....
resetted x times agps data etc, nothing helped...
then i tried GPS Aids from playstore and tadaaaaaaa -> now GPS works....
if i found it earlier, it would have saved me a lot of nervs and time and angryness ^^
what files are responsible for GPS? I played around a little bit, but now i have no Satellites again, and i tried all i did before, i tried different gps.confs and different ntp servers, no succes...
what files can i change again the stock ones to test if it works without a full wipe?
i didn´t think that the GPS is actually such complicated ^^
makes me crazy
AW: GPS dead?!? No GPS Signal
?
Sent from OneX using ARHD
is it possible to solder a bridge between the 2 Contacts responsible for GPS on the Board? So that even if one contact has contact to the Antenna, the other one also has... Because the Antenna also is only one Contact, so they are bridged there, or do i understand something wrong?
hm, nobody knows?
so i think i have to live without GPS
I'm also having issues with gps.. i get 0 maybe 1 sattallite with gps test.Running ARHD 21.0
is there a way to test if its problem with contacts on the motherboard (similar to sqeeze test for wifi) ?
I dont want to open my phone (its pain in the a**)
I hope there is a solution for our problem, would be great but at the moment I dont know what we can do. The only think what I didn't test was to flash stock ruu....
Sent from OneX using ARHD
Later on i even opened the phone and putted some solder to the contacts for the gps antenna and yet the result is the same. I don't think it's hardware,becouse i would't get any sattalites at all,
but i do get sometimes 1 sattalite (no fix to it though). So gps hardware itself probobly isn't defected, so it must be a software issue of some kind.
@W0RSCHD
yeah try the stock rom and report back...
The solder I already did, and tried lot of gps apps and installed Rom with full wipe, all doesbt work. I also sometimes get one sat. But only for a second or two then it loose it and then it doesn't find any sat.
At the moment I have no time to test with ruu, so I have to live without GPS or hope that someone has a solution for it.
Sent from OneX using ARHD
it looks like we have the exact same problem....
hopefully a fix will come someday ..

[Q] Wildfire Buzz A3333 Antenna Problem

Hi All,
My Buzz is having low signals mostly, doesn't matter whether outside or inside. Usually it will not attain full 4 bars & periodically only one bar & no network signals.
Tried inserting an aluminium foil to the bottom cover(i think that's the antenna) through one of the gold connectors but no real difference here.
I googled on the net & it seems that HTC phones are notorious for their low signal.... Not sure how true it is though.
Anyone have any ideas to go around this problem?
Thanks....
I am facing the same problem !!! do you find whats the matter

Press thanks if it helps.

[Q] Service Bars

Yesterday I replaced ad USB board (as an old one become faulty and I have had problems with charging the phone). I can confirm I used the appropriate board model.
Today I noticed that my service bars are not as good as they used to be. Generally in the room I usually used to talk and have weak 1 bar service, right now I have no service. I tested my phone outside as well and have a feeling like the phone has no as good perception as it used to have. Another words the service bars wen down everywhere about 20% or so. Phone works fine and I see no other problems. I wonder is there might be something that affects the service bars hardware-wise ? Any ideas appreciated.

The antenna. I think we have 2, one for GSM and one for LTE.
Google for a picture with exact location and try to re-tighten them.
That's all I can think of.

Thanks for suggestions. Yes the one for GPS works fine as I have no problem with GPS (that is the one on a foil. The one for connecting to the tower is a straight wire. This wire goes from the little board (with USB port I've replaced) to the MB. I reopened the phone today and removed the antenna cable. Tested for continuity - OK, cleaned the connectors but still not luck.
I wonder if this could be some compatybility issue or deffective USB board. The board shows T889 rev1.0 so it sound like it's one of the first ones. Unfortunately I made a big mistake (to late) and thrown away old board. It had a problem with the USB post but there was no problem with the signal strength. I wonder if it is common for the usb board to go bad or if there is anything else I could possibly check. I ordered new antenna cable and thinking about getting another USB board, but if this will not fix the problem I'm clueless. I also restored the phone to factory settings to make sure it is not software problem. I need to use this phone daily at work and I'm really pissed off with the problems. PLEASE HELP
Thank you - ARTHUR
Just a question, ,, have you tried flashing the modem? Not sure it would help but maybe rewriting the radio files will help you.
Good luck

GPS - Problem

Hello guys, I have a really big problem from a while. Actually im not shure from when, but I noticed hat when I tired to use Note as navigation. Problem is that then phone find satelites, lock GPS signal for a while and then starting to loosing signal, resarching locking witch interwals around 5 second and finally shut down for a while.... so for job as navigation is not a best option. I was trying to find any kind of hardware bug. I cleane all antena, motherboard, replace even whole parts including putting different motherboard for testing - yeah I know I should make a copy, but changing board was looking a quicker option.
So I get to point when I know it isnt be a hardware problem... so where I should look for a solution?

Hi, this is due to the Broadcom BCM4752 chip used by Samsung and it occurred after 6 april 2019 GPS rollover. Samsung could fix this with fixed firmware, but Samsung didn't, and I guess Samsung won't. Most of the Note 2 series use this chip, and if there is no firmware update, there is no chance but to continue using it with a GPS signal losing problem.
We have discussed this issue in detail before, please read what is written in the thread below, it will help you. :good:

Thanks for such a quick reply, yeah I read it however I was hopping this is not the case... well still my two other devices work without problem, if such kind of problems appear I just reboot them and this resolvr problem. One of those devices work on Jelly Bean android... im wondering if this could be a solution? Anyone check that allready maybe?
