GPS Fix, there's just one issue... - G2 Q&A, Help & Troubleshooting

My GPS sucked no mattrr what. I made sure the pins do contact the back cover, nothing helped
I took the back cover off and connected a copper wire to the bottom gps pin. This made the find 18 satellites indoor, with excellent signal strength, so yes, the issue is the anenna. I bought a new case, nothing changed. So I decicded to mod it.
I made a thin strip of aluminum foil, connected it to the bottom contact and got excellent signal. Assembled the back cover and.... the signal went BAD again. What I discovered is that if you let the strip stick away from the phone the sigbal in excellent. AS SOON AS YOU LAY THE STRIP FLAT AGAINST THE PHONE THE SIGNAL GOES TO HELL.
There must be some kind of interference or I don't know what. It's crazy, once it sticks out just few cm away you're all good. Press it against the phone, it all goes dead. Any idea why and how to solve this problem?

Fixed my reception

Don't know if this will do it for everyone since I'm not sure if there are several issues, however...
When I bought my Wizard I had superb reception for months but over time it became really lousy. So bad I was about to buy a new phone. However I popped the lid where the antenna is you to take a look at it and when I put it back the reception was excellent again. Didn't give it much thought, I was just glad my problem was solved.
Recently however I have had sporadic problems with my reception and I noticed that I sometimes lost reception (PhoneAlarm tells me if I'm not holding it) and I often had just one or two bars. I noticed that if I squeezed my phone (in anger) I immediately got better reception. For me the problem was the two springy things connecting to the antenna, they didn't always touch. I popped the lid and loosened the antenna foil with a knife, then i slid a piece of paper under it and then pressed the foil back in place. I have had full reception ever since.
I hope this info helps someone.

S100 Loses Signal

Hi, I hope someone can help me.
I dropped my phone a couple of months ago and now I'm experiencing a problem. It appears to work fine for hours then suddenly starts losing signal strength to the point where it goes altogether. I can start a call with 5 bars and be cut off with no signal in a minute even though I've not moved. It will nearly always lose the signal when I'm on the phone but takes longer when just in other use. All remaining elements of the phone work fine. Please can someone suggest what it could be as it is getting me down...thanks
I'm sure it's a hardware problem.
have got the same problem.Did you already find the problem.In the beginning the signal just dropped but know i even cannot find any service at all.
gr
I've had some luck by raising all the contacts under the sim card but the signal still comes and goes when I use the phone ??
Snap!
I droppped my phone the other day and it is doing exactly the same thing. Mine is a Qtek S110. I used to 'lurk' on this forum ages ago.. but [email protected] BACK to seek help! If and when I get my phone fixed I WILL post and let you know what it is, if I havent already found the solution here!
I think it definately has something to do with the SIM holder, whenever the signal decays and vanishes, if I take out the sim and put it back in it comes back straight away. if I just take out the battery and replace it doesn't
ok.. next time i lose signal I will do that. maybe even run some isopropyl alcohol over the contacts to make sure they are clean.
I will keep you posted in my findings!
(oh.. i tried a makeshift external aerial last night to see if I could see if it was an internal aerial fault. It didnt make any difference, so either my homemade job was [email protected] or it isnt an aerial problem, I'm yet to find out!!)
Cheers!
oh poooop..
that unfortunately didnt work for me.. Oh well. i even tried cleaning the contacts and making sure the 'sprung' contacts were connecting with the Sim correctly.
I actually lost signal until it came back 15 mins later.. hmmmmmmm!!!
Can anyone advise where I can look on the circuit board to see if there is any damage. I am capable of doing this and making a basic repair !!
I had a look at the mda strip down guide on here, but I could see any reference to the aerial or anything. I think I'll have to send off for repair! Doh!
I emailed HPC and they wouldn't take mine back as apparently it was not sold in the UK.
I think I'll give xdarepairs.co.uk a go. a mate of mine said they were good n' quick.
merceeeeeeeeeeeeeeeeeeeeeeeee
no wurries!
the unit that sorunded in red (in the Attached picture) is connected to the main board with tiny connector, and this connector is a male to female connector. the male is solderd to the main board and the female to the unit. my guess is that one of the connector parts (the male or the female) was disconnect from its soldering, and you need to resold it. but it is just my guess based on my experience.
I was taking a look at the mda-jam.pdf guide to removing the case and it suggests that the aerial contact on the board you have pictured is with the front panel.
Can anyone confirm if indeed, the aerial for the phone is the metal casing? That would suggest that the dents in the front of mine could have affected that very contact.
Would still like an answer to my previous post.. but I think I may have fixed my phone temporarily.
Using the above information I got a flat bladed blunt instrument (in this case a normal dinner knife) and carefully placed it into the empty sd card slot. Using the diagram from the case removal guide I applied pressure with the knife to the area where the 'aerial connector' rests against the front bezel, inside, whilst at the same time pushing on the front outer casing with my thumb in the same position.
The thought process being, that it may have worked loose.
Sure enough I have noticed a vast improvement in signal yesterday and today. I am going to keep an eye on the phone today when I go out to see if the signal stays up!
YAY!
Okay.. latest update.
The signal did drop out a little bit throughout the day, So I have taken it upon my self to put my electronic training to good use.
Using the (now much read) case removal manual I carefully .. and I MEAN carefully took my phone to pieces.
I was convinced that the reason my signal kept dropping out was either that something had worked loose or that there were some contacts that needed cleaning or reseating.. as I was able to get a signal by squeezing the case at the top.
So.. Here's what I did (In reverse order)
Page 9 straightened and cleaned the 3 contacts on the RHS plastic plate with isopropyl alcohol. Also cleaned the corresponding contact points on the main PCB with alcohol and dried with a lintless bud.
Page 10 3 contact points, top right and top edge left are the contact points I refer to above. Also cleaned the 2 sprung contacts at the bottom of the PCB RHS page 10
Page 16 cleaned sprung 'Aerial Output' contact with alcohol.. also pushed connector outwards to make a betterr contact. Also cleaned 'contact to the antenna' area and dried thorughly with a lintless bud. Any other contacts I could see were cleaned and dried too.
Whilst putting the phone back together I was very careful not to touch any components. Battery contacts and Sim contacts were also cleaned.
One thing to note in the manula is that it it possible to unclip the connector for the camera prior to removing the plate in page 8. However, it is probably best to follow the guide, if you are unfamiliar with the type of connectors used. They can break easily.
My phone booted correctly and is currently on charge.. I am checking functionality at this very moment and can see that the signal is good and all other parts / hardware functions appear to be good. watch this space! It COULD be one fixed phone!!
I can't remember who on this forum wrote the mda-jam.pdf manual, but I would like to publicly thank you as you have helped fix my phone!
I hope its worked !!! Let me know !
OK!
Well so far I have noticed a dramatic improvement on how the phone was. I am sitting here with full signal, whereas on Saturday I had between 2-3 bars.
I lost a little signal earlier today but as soon as I held the phone up, the siganl came back. So, it's not perfect, but the phone is useable now.
As long as it lasts for the rest of my contract, I'll be happy!!
Dood.

Magician Radio issue

Hi,
I recently had a Magician shipped which seemed fine the first day of use, but at the end of the day, the gsm radio icon showed me a no reception, or 'service unavailable' message...
Now, after upgrading the Rom's (several used) and Radio update to the latest one (1.13 as far as I can see), I don't have any reception or 'service' at all...
The gsm radio always shows the '!' marker...
Anyone any idea where to look?
Loose cable, loose or bad antenna, software/rom issue?
Any ideas are welcome!
This device will be my test-unit for xanadux, but I want to make sure it's functional before testing stuff and debugging things that will never work because of a hardware or firmware issue...
Thanks guys!
Great work, super forum!
this is clearly a hardare malfunction. your device may not be identifying the sim card.
thanks for the quick response, but I don't think it's the SIM-slot that is causing me troubles... The SIM card can be read without any problem, and the pin code is asked and aknowledged by the phone. Once in a while I get coverage, but it always looks like 1 bar maximum, while my Trinity is lying next to it, same operator, and all 5bars of coverage notification are there, so it's not that I'm in a dead zone or black spot where there's no cell coverage at all.
I checked the upper back part (after removing the plastic casing top) and checked where the antenna is connected. Once, while holding and pushing onto the metal part that looks like the antenna extension, I got (just for 5 seconds that is) a connection, and signal level of 1-2 bars, but that dropped and stopped after a few seconds already...
I think it's a connection issue of some kind, internal antenna or the connection to it, but I'm not that keen on taking the unit apart to find out it's not that easy to sort the issue out...
Any help, info, ... can help...
Thanks!
the metal plate just below the top-backside plastic panel acts like the antenna.On top side of it there are two legs which connect to the mainboard.try cleaning the two spots on mainboard and the contacts of antenna.
well, i can say this because i solved this problem once this way.
good luck.
Well, I tried what you mentioned: scratched and cleaned the squares on the pcb, straightened the connecting metal parts from the back plate, cleaned all contacts: no solution...
Any other ideas?
Possibly a sort of switch which makes the device choose between internal or external antenna? What external antenna might fit?
Thanks guys!
Well,
I got my hands on a 'broken' I-mate Jam (got stuck between the car door, screen is totally broken, pcb is fine) and replaced the antenna block: FULL RECEPTION...
at least, for half an hour.. after that: reception dropped, and again left me with the "!" mentioning "no service"
I tried switching the pcb's but for some odd reason, the screen didn't come up good... The backlight didn't turn on and the screen was all striped and smeared...
Is there a difference in pcb versions, connectors, screens?
I thought Magcian = Magician, but now I'm thinking there are different models around there...
Bon... so I'm looking for a pcb of a Qtek S100 now... to switch that one with mine, and see if that helps...
really strange the reception was 'perfect' for about an hour, I even succeeded in making calls with it! No jitter, no drops, perfect reception, and then: BONK, over with it... nothing left...
Any ideas on this one, or any ideas on how to get the I-mate's pcb working in my Qtek?
Thanks guys for the info and help!

XPeria Poor/Fluctuating Signal and GPS Solution

Looking at the results of the xda-developers pool I decided to get an XPeria as it clearly out shined all other phones. I got X1i this Saturday and was shocked about the poor signal strength. I was so looking forward to using this phone and keeping it but was more inclined in sending it back. Now after a couple of days just browsing the developers site which I am used to as I had an artemis before this. I see this was not the last of the problems. There have been mentions of overheating and GPS lag as well as the WIFI being rubbish. I have found the following problems
1. Signals fluctuating and mostly no service when in hand even in some good reception areas. Normally on H when in the carry case but switches to G as soon as held in hand.
2. GPS is frustrating. My artemis used to lock within seconds while having an upto date ephermis file. But even with AGPS and recently downloaded ephermis file, I had to wait over a minute to move off. It locked and then it lost and then it locked again(This was when it was in my hand). Once locked it was stable. It was on Google maps by the way.
Right for these, I have found a temporary solution and we have to work on it to make it a standard solution for all X1. Apparently the signals definitely fluctuate when you touch the lower metallic part on the back which has SE logo on it . The opinion on the forums here is that it may block the signal. I think otherwise as I have covered that area without touching the panel with my hand and there has been no signal drop but as soon as you have the slightest bit of flesh on that area the signal drops at least two bars. This led me to believe that there is an electric conduction or possibly u earth the antennas as they seem to be touching that panel from inside as it has been pointed out before.
So simple test was to put a cling film on that part and then test so I did and walah!! There was no signal drop and it worked flawlessly. I think it’s the same problem with GPS as well.
Now I couldn’t carry on using my phone half mummified. I had to take the cling film off. This is possibly the solution to everyone’s problem but I need someone to suggest either a plastic cover for that area or some sort of coating which does not conduct electricity. I think that will definitely sort the problem.
I think you've got a faulty X1 there mate..
Can you take it back to a store and compare it against another one?
The signal is weak on this compared to some other devices, (it's not as bad as the vario though), however I've never noticed a drop in signal by holding it, so I suspect somethings awry with the one you've got..
GPS signal is very very good with the later radios, what version have you got?
I get a lock within 2 seconds (8 seconds from hard reset or flashed a new rom), and it's very very accurate when it does lock.
My GPS works very well (better than htc cruise) also with previous radio.
So I think you have a fault X1, like say by fards.
I'm with Fards on this, I don't get issues when holding the phone and GPS is snappy.
crabby
Thanks guys. I know it has been discussed a million times before but I have compared the phone with other XPerias and it is the same. There are atleast 4 threads pointing out the same. My X1 would have better signals than my artemis as long as i dont touch the back base. Have you all got silver X1is? If so then can you check if you touch the back panel which i mentioned, if there is any fluctuation in the signals(its not instant it takes about 10 seconds for the phone to show the loss of signals).
I have updated radio to 55 and tried the two new stock roms which are R2A for O2 and 010 generic. The phone still looses signals but not completely when i touch the back panel.
About GPS, it does get a lock very quickly but looses it for a short while when i touch the back.
Anyway if someone else comes accross the same problem then please write here as I am sure there is a solution to be found. I was looking at the following
Clear coating
Antistatic spray coating
I must have missed those threads then.
I have a black x1, and definitely don't get any of those issues.
gps is steady and strong.. monitoring it now... as I type. 6 birds locked standing next to window in house hdop 0.6m which I think is very very good
gsm signal on 2 bars and steady
I had the same issue just once. And even when X1 was in the Brodit car holder.
In my case the soft reset was sufficient to solve the problem. But I guess that you already did that.
fards and pelriog? did you experience any fluctuation when touching the panel?
These are the links to threads
Thread1
Thread2
Thread3
Thread4
Same here, touch back panel, hold for 10 secs and signal drops 1 bar. Currently on 3G network, going from 2 bars to 1.
(And yes, my W810i gets a way better signal in low coverage areas. However, usually not a problem, since I hardly encounter Vodafone low coverage areas in The Netherlands).
Tested 5 times. Dutch Vodafone X1i, R2 stock ROM & stock radio.
Ok I did the touch the panel thing and my bars increased by one... hmmm perhaps there is another faulty batch out there as I get great signal (touch wood) and my gps is very responsive and accurate...
Silver X1 here.. Been touching it up for about 15 mins now
It does seem to drop by 1 bar when touched, but also drops if i just put my hand really close to the back without actually touching. hmm..
what concerns me more is how it just drops the whole line randomly and gives an x then has to search again. Lost a good few calls from that..
well here ive got no problem at all with signal.
But GPS does suck even though most people everywhere say X1 GPS is awesome.maybe it is just my zone/country.. could that be possible?
uhm.. of course not, their satellytes afetr all.
I have disassembled my X1 myself and found that under lower part of backside (piece that have SE logo) is an antenna of some kind.
The antenna is a thick circuit that ran on top of another piece of plastic that cover the loud speaker.
The circuit only have 2 contacts to the main PCB.
My guess is that the reception site of either GSM or GPS is on that part.(may be bluetooth or WiFi too, but I think that's not it)
I wonder what SE/HTC engineer is thinking, putting antenna on this part of the phone! (covered with my hand everytime I use it!)
The solution is "use bluetooth headset" and "hold your phone upside down" and you will be fine.
Yeah, mine loses a bar when touching the metal case at the back, I've not lost any calls (that I know of) because of this though.
I had a look under the speaker section myself last week, and can confirm the antenna circuit over the speaker section. Underneath there's also what looks like a tiny external antenna socket... we could mod our experias to have a rubber duck aerial? Who's up for walkie talkie lookalike xperia?
lol @ walkie talki and upside down. I think the designers have done a very poor job as far as the antenna location is concerned.
Tumpin does your phone loose all signals when in your hand?
Taking this seriously as suggested in my first post has anyone tried putting a cling film on or to that matter anything to cover that area and holding the phone. I did it with the cling film and there was no drop in the signal. So i think it is just a matter of us using some kind of invisible coating or cover on that area so there is no static conductivity. Look at post #5
I would appreciate if everyone gives there suggestions as well how to deal with it. For the people who took the phone apart you could have put something on the inner side to block the static discharge.
I returned my xperia for the second time for signal problems. The problems started after it was repaired for the crack in my case. After that the signal was very poor. GPS was not working in 90%. I wait for 15 minutes for signal, but the only thing that happend was heating the battery. Also HSDPA have a weak signal. In most times I only can use GPRS. The first time I returned the phone for this problem nothing changed. And this time I had a new crack in my case, so I hope they send me a new one!
Im using a X1a and I find its GSM/3G reception is really poor, I already upgraded the radio to the latest but its still the same poor poor reception. Specially when Im using the metal case I frequently get drop calls on my device

Just curious! Any chance that you see what for are the two metal plates contacts from the metal cover of the phone? Those near the SE logo. These two and the other two towards the camera are there for... what? The metal cover is used for something as when you rig in the phone and all four contacts are "online" but what for? Thanks!
I have a black X1i and noticed that reception increased when using it with the keyboard opened in horizontal position.
Same here, I tought it was because I open my metal case that is why reception goes up.

Anyone else having navigation issues?

I am currently running google maps 9.42.3. Android 6.0.1 Kernal 3.10.49-g6d40c12.
Last night, while taking my grandson to a soccer game, navigation would not update my position or take the next turn. I rebooted and that did nothing. As in the other thread, my GPS is not great. However, I could hit the location button on the map and it would get reasonably close to where I was at. Certainly close enough to suggest the next turn.
I know this has worked on this phone in the past. Is it possible that I "broke" it by turning off Google Play services access to my contacts? I now get messages saying that maps won't work properly because play can't access my contacts. I could understand why maps may not be able to navigate to a named contact if it didn't have access to my contacts but why would little ole me affect navigation? What could my limited contacts possibly have to offer to bring what used to be a great app to the point of being non-functional?
Thanks,
Wade
For what it's worth, Play Services needs access to pretty much your entire phone to work at all. And contacts is also tied to things like your Dialer, which is tied to your cell antenna... you get the picture. I found out the other day that if Google Maps can't get a fix from GPS, it takes a fix from whatever cell tower you're connected to, even if that tower is 10 miles away. More towers in your area, the better chance you won't notice the difference.
I am having navigation issue.
I don't know very much about the problem but you can fix navigation issue by just touching to the Harpia GPS device by removing the back cover of your mobile. It actually works for me every f***** time.
10 Seconds GPS Redneck Fix
Using @ashishwebmail touch tip I devised a 10 second solution for my XT1609 G4 Play. Sort of a temporary redneck fix but it works.
(Next I'll probably be experimenting with very thin conductive tape that might fit within the back of the phone.)
I straightened a paperclip except for the end with the bend upward. Took off the case and phone back. Put the paperclip in my case with the upward bend flush in the case corner so it contacts the GPS antenna. Replaced phone in case without phone back. Voila!
Getting a GPS fix every time in 2-6 seconds using both GPS Status and GPS Test, indoors with WiFi on or off!
Unable, as a newbie to this board, to post a link to the case I'm using. It's my favorite smartphone case ever, and cheap.
It's the one on eBay with the title "Slim Shockproof Rugged Hybrid Soft Silicone Case Cover For Motorola Moto G4 Play"
Conductive Tape GPS Fix Confirmed
Removed the case and phone back. Laid a 2 mm wide strip of aluminum tape from the top GPS corner, along the edge of the battery compartment, to the bottom corner, careful to keep it away from the phone back notches. Doubted the adhesive was electrically conductive as I think it's just cheap construction flashing tape, so I folded it back on itself on top of the GPS antenna to be sure it made electrical contact with it. Replaced phone back and case.
Getting GPS fix in 1-3 seconds indoors every time in 20 tries! (This is with WiFi on or off.)
I had an issue with the GPS not working for navigation on the Moto G4 Play and I ended up having the phone replaced under Motorola warranty, it was a bad GPS. This seems to be a fairly common issue for this model.
