GPS Dropping - LG Optimus G Pro

Does anyone else have this issue? My GPS loses connection to the satellites every couple minutes. And yes, I have the latest map update.

Must be the bug in update. Try to use 3rd party app! Just because i never updated mine, and is working like a charm

The GPS in my phone is not very accurate. Maybe its just this phone. I only get relatively good GPS reception at night.

Thanks guys. I'm starting to think it may just be this phone as well. The first map told me I was 3 miles away from my house....lol...and the second was accurate but keeps dropping the signal. I do have carhome. I'll try that and see what happens.

I also have this issue though the GPS (which is used a lot by me) was quite OK in the beginning after I bought my LG OG PRO.
I read in one of the Samsung NOTE forums that people mention the same problem claiming that the drops come when there is an "interruption" (which can be an incoming call or SMS or switching from 3G antenna to 3.5G for example). After reading this I realized that my GPS gets lost always after an incoming call plus I see at least a couple of places along my daily driving routine where GPS is lost exactly at the same place every day (making antenna switch assumption logical).
There were no any conclusions or suggested solutions in these forums, people even do not know if it is software or hardware related.
Anyone has such an issue too? Any recommendations for possible fix?

I can't believe but it seems I solved the problem with GPS - 15-20 seconds for GPS lock, no dropping and GPS test application shows very nice picture of 8-9 satellites constantly locked up while most of the signal bars are yellow (i.e. the signal strength is good).
I searched a lot as it really bothered me because I use my GPS very much plus I can say that beside this annoying thing I am very satisfied with my LG OG Pro, but nothing helped until I found this video: https://www.youtube.com/watch?v=QBpNtWvY454 (it explains the solution for Nexus 5, but my problem is identical)
Basically, the problem is that there are special contacts on the motherboard connected to the GPS antenna which is part of the back cover and the contacts are not tightened well to the GPS antenna (look at the attached picture where I put the red arrows at the relevant places). Due to the bad touch between the contacts and the antenna, the GPS does not work properly. So, all you need to do is to remove your back cover, gently "un-glue" the GPS antenna end (the rectangle part on the back cover containing 2 golden dots), lift it up a little and put a piece of paper that will tighten the antenna and mother board contacts when the back cover is returned. Good luck.

It is NFC Antenna, you cant fix GPS this way.
I have same issue, but i think NFC and GPS antennas are different. I am disassemble the phone and pull up all golden springs - but gps still very weak(((
Any solution?

same GPS problem for my g pro.
GPS is weaker and weaker

I realigned all the pins inside the phone and fixed it for a bit, but the signal was still weak. I figured it was the modem. I installed a custom rom and it worked like a charm!

[Q] What could be causing Data/3G connectivity problems?

So I recently was able to replace my Samsung Fascinate because of the ED05 Update not fixing the missed call problem.
I recieved my DInc2 yesterday at 3pm & have noticed that it takes a minute or more to open links from Twitter in Dolphin browser hd and that the 3G icon and bars fluxuates from no bars, no 3g icon to full bars to 2 bars etc..
Just wondering if you guys no of a simple fix, if its a known issue, and your thoughts
Thanks

If you're not in a very well covered area, it seems the Inc2 doesn't work so well. For me, being in a well covered area, data functionality is actually exceptional (2mbit speeds not uncommon, usually 1+mbit in most areas, and only a few areas under 1mbit).
This seems to stem from the type of antenna being used. There is a discussion on trying to figure out the best/easiest way to fix this. So far what has been tried is aluminum foil in the back cover (this doesn't seem very well substantiated), small bus/magnet wire (personally tested and works to boost signal, but may not be worth the trouble), and the possibility of conductive ink to extend the existing antenna (possibly the best solution...if it works at all).

Possible fixes for very poor GPS signal

I have a One X which i have converted to the new layout. I was running Lollipop and i noticed that the GPS signal was very VERY poor. It never gets any fix and can only see 2 - 5 satelites, where as my Sone Z3 Compact in the very same spot can see over 20 satelites and gets a fix almost instantly.
I have tried a few things.
I have tried to do what is described in the following guides two guides:
http://forum.xda-developers.com/showthread.php?t=1930094
and
http://forum.xda-developers.com/showthread.php?t=1239713
Which didnt work. Then tried to install the following rom for the new layout:
http://forum.xda-developers.com/htc-one-x/development/stck-rom-sense-5-debloated-4-18-401-4-t3111605
Both with the stock kernel and with the sweep2wake,doubletap2wake, etc. but same result.. Only getting 2 - 5 satelites and never get any fix
What can i do at this point? Should i try another Radio rom if such even exist and if so where can i get it ( I'm running 5.1204.167.31 now ) ?
Pulling up the tabs wont solve the problem permanently. The tabs will with time retard to their original position or lower because of metal fatigue.
Pulling them up again will make them break after off after ~ three times of bending. They are fragile.
My original solution for the GPS antenna some years ago was to cut a credit card to small rectangle pieces that fit right below the connector.
Carefully glued into place with Loctite 401. This prevents the tab to retard any further than the thickness of the card. I was lucky to find out that the thickness was just right. I got a lock in about 30 seconds after this mod being outdoor.
Some years later for the wifi antenna I instead soldered a thin cable from the board to the antenna. The wifi reception is as good as it can get.
If you have some thin cable that you can use. Must be around 3mm OD (outer diameter) or thinner. Or you wont be able to fit the case back again.
This would be the better option to solder cables between the antenna on the case and the board.
One X never had good gps ...don't expect it to compete with other devices.
GPS is working fine for me. But I have to say that I disassembled HOX (screen replacement months ago) so I put those GPS pins a bit higher. Other thing that might help is to enable all location services (google, GPS etc.) in settings, then reboot phone and use GPS Status & Toolbox app (first, delete A-GPS data and then download A-GPS data). First fix might take some time, but other are fast (I only leave GPS sensor checked after first GPS fix - so no Google Location services enabled).

Poor wifi signal issue

Hi all!
I would like to know if anyone here has noticed if their Mi5s has a poor wifi signal strength compared to other phones they had.
I've used a Samsung Galaxy 5 NEO as comparison. While the samsung brings me nearly full speed at a distance of 10-15 meters from the wifi device, the mi5s just brings me 1 or almost zero if I move just 3 meters far.
There's something I did that maybe has broken the wifi signal. I had an accident where some coffee was spilled in the phone, and I had to unassemble it to clean the speaker that wasn't working properly. I just cleaned the speaker module (it can be deattached) carefully with little water and it started it to work good again. But not sure if it was because the unassemble but I noticed that the wifi signal was pretty poor comparing other phones.
I'm starting to think in changing the rom now with all the kernel hype and I would like to know if I'm the only one, because if it is that case, I'm probably going to unassemble it again (not a easy task) and recheck if I missed to connect something, but if I remember correctly, the wifi antenna is nothing more that just a metal part attached to the board.
So. Am I the only one who noticed this or just my xiaomi is broken?
many thanks!
Mi 5S have good Wi-Fi module, at least better than Samsung Galaxy S6. I think that your problem is connected with that accident. Metal can oxidize when the water touches it. I think that you have something like this with your Wi-Fi module connection.

Gps improvement (a weird solution)

So currently I'm having a major issue with my gps since it was so difficult to find any gps even outdoor, and even sometimes it didn't even found any gps at all. I've tried to reboot, change gps.config, change roms, reflash miui. Any of it doesn't solve the problem.
So I did some research a little bit about extending the gps antenna using wires. Then I peel the casing.
Before attaching the wire, I just try to test the gps. And surprisingly, the gps works very well. I even managed to connect to the gps indoor. The screenshot attached is the result of indoor gps test without the phone casing and antenna extension.
So what's the exact problem anyway with vince?
Does the metal casing interfere with the gps?
Do I need to use the phone without the casing?
In my case, yes I did found that that's the best solution. But it will not be practical to do so
Improvement workaround
Here is another method I used to improve the gps reception. The more practical way.
Simply take a small flathead screwdriver and scratch the contact point at the phone casing. I'm not sure which one is used for gps so just scratch every contact point in the picture.
Make sure the contact pin in high enough in order to make full contact with the phone casing.
Install the casing and the gps worked wonderfully just like without the casing earlier.
What definitive (and practical) solution did you find?
Actually, all you need to do is to press the case from behind, around camera 1 cm from top x 1cm from left/right + 3cm from top/1cm left/right.
My signal went from 0 inside, to 5 meters accuracy. Outside 3 meters. Device only. You can literally delete gps.conf and flp.conf file on redmi 5 plus, and it won't affect gps SNR ratio at all. It's like it isn't reading them. I've been messing around with fixing the issue for 3 days, read all possible posts on the subject, rooted my phone, experimented with everything available till this date. It's just upgraded version of what you have here
It seems there's a design flaw, because GPS antenna and contacts are on the back, and during time, that back seems to bend upwards, which is causing loose connection. One push restored everything in it's place.

GT-I9195: Where is the GPS antenna/connector?

Hi,
I have an old s4mini (LTE) which I have been using as car and bike GPS for many yrs. The GPS was always great but last autumn it stopped working. I put it in the drawer and have been using my old ASUS Z00ED since then which has a better performance, a larger screen and a perfectly working GPS.
Still, the ASUS is way too big to use it as bike GPS while the s4mini's size is perfect, so I want to revive it.
Currently, the phone sees some satellites (with a very bad signal strength or SNR or whatever it is) but is unable to use them, even after trying to get a fix for a long time. The screenshot was taken on my balcony outside where my other phones easily get > 10 sats fix. I am quite sure this is a hardware problem as there was no software update before the problem occured. The phone then was on the latest official LOS 14.1, now I have test installed AOKP 2019-10-25 with no change. It may be a corrosion problem as the phone lay in the mud and rain for an hour after a severe car accident, but after cleaning it, it had worked for 2,5 years without any issues...
So now my question: Where is the s4mini's GPS connector and antenna? I would like to try and fix these. I have a second s4mini with cracked screen which could serve as a spare parts donator.
Take a look at this video:
https://www.youtube.com/watch?v=4sOKKoxu3L4&t=275s
At about 2:40 and 9:15 this guy explaines the location. Maybe skip ahead a few seconds.
I had also an bad GPS receiption and I "cleaned" with a screwdriver the part at 2:40 in the video. Afterwards it was shiny again. Also I "cleaned" the part (of clips) on the board and I did also lift up the board a bit and put a piece of paper behind it so (I was hoping) I get an better connection between those two parts. I am pretening that that helped.

Thanks, at the moment I have it back working. I'm afraid the problem was more due to the GPS rollover than due to the antenna.

I've heard the GPS Rollover isn't an issue on most devices, and a lot of patches are softwrae based. The epoch is set entirely in software iirc.
