I posted this message at www.pdaphonehome.com but I thought I might give it a shot here and see if I can get diffrent results.
I'm in Sydney Australia and have recently puchased (brand new.. not off of ebay or anything) the O2 XDA (32/64mb). Rom version is 3.14.17 ENG with a Radio version of 4.16 and have encountered the dreaded SIGNAL LOSS / REAQUISITION problem.
I switched from a Treo 270 (which had the dreaded back light problem) and absolutely LOOOOOOVE the XDA (plus the fact that I can code VB apps for it too is kinda nice without paying for the dev env) aaannnyway....
(is it me or does it seem like most PDA-Phones have at least one Dreaded Problem).
I'm currently with a carrier which has almost no signal at my workplace (vodafone) and am at least 12 months away from my contract ending so swapping carriers to the better Optus or Telstra is a no-no.
I've managed to trawl around and managed to find some information on the Signal loss / reaquisition.
1) The phone takes an awfully long time to reaquire a signal after coming back from an area with almost no signal. I've managed to time it and on average it seems to take about 10-15 minutes to reaquire. It also needs a STRONG signal to reaquire it and will take longer to reaquire if it's a weak signal.
2) Occasionally the phone gets "stuck" and while it reports a full strength signal, no-one can seem to call or send SMSs
I've tried to use "Phone Today" and it does seem to make little or no diffrence in my situation.
From what other sites (as well as this one) have reported, it has something to do with people only in fluctuating areas of signal combined with a long refresh interval on the phone rather than a defective phone. Am I right?
What I'd like to know (throught your wealth of contacts) is the following.
1) Is O2 Aware of this problem? I've seem forum postings where O2 have admitted to it. Can anyone confirm this? I managed to contact O2 Australia and they've denied (surprise surprise) any knowledge of the problem. Mind you I'm not sure how prevalent the XDA is in Aus so the guy on the phone may have been genuinely ignorant of the problem)
2) Can anyone confirm whether O2 is working on a patch or update for this. I know an ETA is too much to expect but some acknowledgement would be nice.
3) I understand that the AT&T SX56 is practically the same machine and it has it's refresh rate set to 90 seconds as opposed to o2 which I'm assuming is every christmas (but only if you feed it cookies). Would fixing the problem be as simple as using the radio rom from an AT&T on a XDA?
4) Is there anyway to hack the radio to up it's refresh rate? (might breach some copyright laws ... apologies if I've stepped on anyone's toes)
5) Is it true that when it tried to reaquire a signal, it goes into a high frequency seach mode (or something like that.. I don't know.. *sigh* ) which chews up more power? Does this mean that if a more frequent refresh rate were to be implemented, the battery life would decrease significantly?
**new addition**
Since I do have a little knowledge about emVB may be a temporary solution might be possible if I could code one.
Is there an API / for the GSM component of the phone. I noticed the "register on network" button seems to force the phone to reaquire the network if there isn't any signal. I would be nice to write an app to detect a "no bars" status on the phone and get it to hit the refresh button (or at least call the function) every minute or so until it finds a signal.
Any hints?
I may be hoping for a little too much here but it never hurts to try right? Thanks in advance.
XDA fails tto turn on phone
This looks a lot like "XDA fails tto turn on phone." in http://www.sourceo2.com/Communities...tm?frameset=found&NewsGroupID=8&iPageNumber=1.
Thanks for that I'll have a look-see. Didn't know about the SourceO2 site's communities.
I checked the site and it seems that it's pretty much the same gripe everyone's whingeing about. O2 doesn't seem to say anything about it and some poor guy called "xdaguy" seems to be taking all the heat. I don't envy him.
I'll live with it a while longer if not, it's back to the store and since there doesn't seem to be any other PPC phones apart from the XDA here, it's back to the treo.. Booo Hooo.. No MP3's for me anymore
Thanks for pointing me in the right direction anyway.
Paper clip to boost signal
Yes, a paper clip...
I too have experienced just the other day A weak signal to a no signal at all...anyhow here's how to dot it ( at your own risk of course)
1. Bend to straight the paper clip
2. Strip the plastic cover off the metal paper clip using a blade or a small box cutter.
3. bend 1/4 of an inch at a right angle
4. Remove rubber cover beside camera lens
5. Insert the 1/4 inch bended paper clip into the female socket
6. wait for signal
Note: this is only TEMPORARY of course as am looking into the after market antenae booster
hi - looking for a solution to this. is there any?
if my phone loses the signal it won't regain it.
I'm sure i read somewhere that this is actually a design fault and the xda (version 1) is only designed to try to regain signal for 30 mins then give up. That right? Can it be fixed?

I used to get this but a soft reset usually got it back online.
I'm noticing that I'm pretty consistently losing a bar of signal (cell & wifi) when I'm holding my Thunderbolt. Also, streaming music to a bluetooth receiver across the room, it cuts out a lot more than my OG Droid did when I'm holding/messing with it.
Anybody else? Is this normal?
I notice it. Drops from 4g, 2 bars, down to 3g almost all the time when i pick it up. Happens mostly inside buildings.
During antenna gate, it was shown that almost every phone has some effect when being held.
I haven't really noticed it behaving that way. When I pick mine up the cell signal bars will drop a little, but then they go right back where they were a few seconds later. 3G and 4G so far have been unaffected.
Most recent phones have the antenna in the bottom, so you have to leave it exposed to not block the signal and cause attenuation. My nexus one I can drop all the bars covering the bottom.
I'm 99% positive the antenna is placed about an inch and a half from the top of the phone. Hold the phone on the bottom half and all is good. While holding at the bottom with one hand put your other hand around the top and you'll get an instant signal fade...

Hmm. Thanks for the feedback guys. Good to know it's not a huge problem. And my issue doesn't seem nearly as bad as blusgtone's.
It does seem to occur when I touch the sides of the phone though, not really the bottom, or even the back. I can make the bars go up and down by switching back and forth between holding it at the top and bottom with my thumb and middle finger, to the sides with the thumb and middle finger.
Oh well. It still kicks ass.
no I love my sgs2 and so does every that holds it, ive a major issue that i thought was caused by switching from orange uk to o2 uk, but as it happens i have full signal when the phone is rested down... however when i pick it up it drops signal... more often than not the signal completely drops out as does the call and sometimes it just goes down to 1 bar... does anyone else have this problem? ive tried my o2 sim and my orange sim its the same for both... is it possible i have a defective handset ? weak radio ???
heres my quick vid to show you what i mean, apologies for the video quality... filmed on my bb9700
http://www.youtube.com/watch?v=9VthdB4V3D8&feature=channel_video_title
well the GSM and 3G antenna looks to be located in the bottom, back part of the device. so this seems like the exact place your hand would be covering when holding the phone, so i can easily see some significant signal attentuation happening with this phone.
i dont know where the antenna was located on the original galaxy s. but all phones i own always have attentuation. not much you can do about it i'd guess.
Applies to all wireless devices - signal transmits worse through your hand than through empty air. Rules of the universe.
However, I can't seem to replicate what you're seeing. In order for bars to drop, I have to block the entire bottom of my device using both hands. Holding it in one hand doesn't seem to be causing a drop for me.
But again : air > hand for signal transmission.

That's right, quick start guide shows the location of the antenna. If you look at the back of the device, the antenna is in the lower left hand corner, opposite the speaker.
When holding the device in your right hand, it should rest in your palm.
Actually holding the device in my right hand doesn't seem to be affecting my signal though, for some reason. I might just be in an area with good signal though (3 bars of h+, stays at 3 bars when holding it in 1 hand, drops to 1 bar when covering the device completely with 2 hands, and then changes to edge with full bars).
I just tested with my S2 and I had no problems whatsoever.
See my youtube channel (../user/Poppefieke) Can't post links yet.
I have some other S2 video's there too
i think sampullen who has been posting quite a few vids on youtube is going to cover this now too, see i hold my sgs2 in my left had for holding when im surfing etc but also when im on calls...
its good to hear some of you cannot replicate this, maybe mines faulty might try to exchange for a new 1 just to be on the safe side
OMG!
can more people confirm if this is real?
is it as bad as the antenna-gate issue from apple or no where as bad
Hey (samjpullen) here
I have been doing the tests like Sticky and have been getting some rather conflicting results to say the least.
I am not in the best area for Orange so i get a weak signal most of the time, when i do the test infront of my iMac and extra screen with the TV, Sky (you know the drill) on it seems to drop down from H with 1 bar, then down to 3G then down to G and then it can jump onto the Edge network (rathe strange)
But when i do this same test in other rooms e.g bathroom, other bedroom, even downstairs with the tv etc on it is fine!
So my guess is that it might be my rooms location and maybe all the electrical equipment within a small space.

im hoping no where near as bad and im hoping that i was the only affected, one chap has placed a video reply to mine showing he doesnt have the issue which is good news, lets hope more can confirm im rather a 1 off and that if i replace this unit all will be well...... fingers crossed
cheers sam,
btw ppl follow sam on twitter, guys good!!!
The wifi signal strength is normal and good before, and it becomes worse about one month before, the wifi signal strength becomes weak, I have tested with other phones. At the beginning, I think it is the problem of the MIUI, then I flash Cm14.1 to see, but the wifi signal strength still the same. Can anyone suggest any method?
how exactly did you measure wifi strength?
and what can possibly go wrong with weaken wifi signal?
care to explain?????

I have already fixed the wifi problem with opening the case of the phone and put a soft metal clip between the two wifi contacting points and the antenna.
I think it is the problem of the aging of the the two wifi contacting points .

I did some search on the internet first, finding out that many ppl having the same problems due to the reasons of falling down the phone on ground.
It is easy, First open the case, then open the upper part which is with 4 screws. then remove it and you can see there is two contacting point on the upper right side.
They are are the contacting point for wifi.
Just use some soft clip to increase the contact area and install back the upper part. that's all

i hope you already solved the problem, but if not, try this out, it work for me at least now my redmi note 3 wifi keep connect and the signal increase, first open your phone back cover (you can use thick material such as guitar pick) then at the top remove 4 screws (one screw is hidden in the back of small mi sticker) then remove the black small cover, there at two contact point put something (for me i use aluminium foil, i take it from coaxial antena cable, cut small square or so put in there) that's it put it back, try to test it first before you put the cover back because a little bit hard to open the cover though. goodluck....

This works in Xiaomi Redmi 3S? I am with the same problem, but i am not sure how to open it and where are the part that i must put something in that two contact point.
This is a very weird issue. I had very good wifi strength before and with the miui updates the signal is very weak now. Redmi 2 and any other phone has better signal.
I have the same router than before.
But its strange that other ROM also has weak signal... Because redmi note 3 pro used to be considered a phone with wifi signal strength
I have my phone suddenly got low wifi signal. I try your suggestion, and it works. Wifi signal is as good as new phone.
I do both put paper under the pin to leverage the connection point, AND put aluminum foil to the contact point in the small black cover to increase the contact area. Not sure which action do the magic

i need to try
As the title goes I tried to make a GPS fix buy adding a little thin plastic under the pins showed in the video tutorial I used but after assembling back the phone noticed that I cannot connect to 2G anymore. I switch to 4G and 3G with full coverage but when I try to went back on 2G the network signal drops and phone says "Emergency calls only". I opened it again and removed the plastic board and switched it on and got slmost perfect 2G coverage but my microphone stopped working - nobody was able to hear me speaking so I opened it again and added a little card board piece on the place and now I have good mic with good 4G/3G signal but again with no 2G signal again. Can somebody tell me what I'm doing wrong ? Also where are the exact places of the 2G/3G/4G/GPS antenas ? I travel a lot on places with low 4G and even low 3G coverage so I really need the 2G mode again. Please help me fix it as it was before. I need 2G more than GPS so if somebody tell me how to reverse this would really appreciate it, thank you !

Ima follow this one closely. Mine has the very same issues ive bassicly asked the same thing
Mine does it one all three. Rarely picks up 2g gsm network gets crappy 3g and lte. I use lte discovery to verify all this. Now i have noticed that if i pinch the chin or hold the phone like laying in bed only by the chin i get killer signal and even pick up 2g at the same time as lte.
I watched other devices all get band 5 lte and gsm at the same time.
I cant find any confirmation on where the antennes are even located in this device.
Today I noticed that my sim tray stays slightly out of the phone body so I tried to push it in and it wasn't going any furder as before. So I though there must be something in the tray preventing it to push in till the end and I used a magnifyer to see inside and noticed a small plastic that seemed from the same material of the pick I used to open the phone so I got it out and now the sim tray is closing nice again and now I'm able to connect to 2G but still the reception is not good as it was and it drops from time to time... Still this is an advance in the right direction. I think I had broken or bent or moved something slightly off place from these several interventions so I'm f****d up.
Please guys don't try to make any gps fixes because you will do more harm than good ! That is my advice !
If still somebody can help me, please write ! Thank you !

Please share where the f**k is the 2g/3g/4g cellular antennas PLEASE !!!!
Nobody here is engineer at LG. And nobody here has any real solution for GPS / 2G / 3G fix. Looks like GPS breaks again even after sending it to repair. This LG G5 has been the crappiest phone I ever bought. I'll be buying a G6 soon.

The 3pins in the video are for the Volume buttons. The REAL GPS antenna are the ones next to the headphone jack.
So far I experimented that the cell antennas lies at the top of the phone since covering the top-middle section of the phone Cell signal drops.
Maybe the plastic shim you put in is too thick that it's interfere with other internal components, like the black RF antenna ribbon that runs across the top section of the G5. See if removing the plastic piece resolves the problem
Hi guys,
Just want to let you know that I gave the phone to a service and they found out that I broke some of the pins even without noticing. That is why this problem occured! They were able to replace them so now my phone is live and kicking again with full network coverage on all bands (2g,3g,4g). So happy with it ! So go ahead and bring your phones to a repair service center and make sure it will be a good one! First I went to affiliate LG service and they told me that most of the things are unrepairable and will have to change the whole motherboard which costs as a new phone so I lost any hope fixing it but later a friend of mine recommended another service where the guy told me he will inspect all the parts of the phone and will call me if he finds anything suspicious or broken. So I left the phone and after 2 days he called back and told me that 4 pins were broken and 2 more damaged and bent badly. He also told me he thinks that if we change them the problem should be solved so I agreed and he did fantastic work on the phone and now works as new !
So don't be disappointed and find a good service where they can try to help you. Also when you are doing some mods to your phones please be very careful!! I confess that I wasn't careful while doing the mod - I was at work and even didn't had the necessary tools for the task, also the colleagues were around and distracting me so I wasn't able to focus entirely on the task and did more harm than good! Good luck !
Thread may be closed, problem solved !
