Gps fix for note 3 - Sprint Samsung Galaxy Note 3

So, I've been trying to get Gps working properly for weeks now and nothing.
Factory resets
Different roms
Everything
I read somewhere that the screws on the back get loose so I tighten them and full 100% Gps.
Just thought I share because I've seen people with Gps issue on stock.

Take those 12 screws out,gently pry/remove backing up and in the upper right you'll see an orange-ish rectangular chip,press back into place with thumb.(Got an audible click with mine),replace screws and voila! Near instant GPS lock has returned.
All of my screws were tight too.

On mine I lifted the metal tabs on the top-left corner once you remove the screws and cover. The top 2 metal tabs are the GPS and the WiFi, they come in contact with the antennas in the cover, over time they get pushed down from the pressure of having the phone on the pocket, etc.

Having the same issue with GPS. Will disassemble and check then report back.

I have some troubles with my Cingular 3125

1- it's reboot many times without any reason(I read one thread about it but i dont understand what to do!!)
2-sometimes 2gb microSd card loosing?(i cant open it from phone...only rebooting helps!!)On other devices card works good!
The usual reason for a 3125 rebooting is that the battery cover has gotten worn down to the point that the micro-switch under it is not fully depressed. There are multiple potential wear-down points. The hooks on either side and the tabs at the bottom can get worn or even broken. There is also a raised pad at the lower left (looking at the cover from the inside) than can get worn, as can the contact point on the switch.
Typical solution, providing the hooks and/or tabs are not totally broken off, is to put a thin piece of plastic or cardstock between the microswitch (lower right of the batter compartment) and the cover. It's a temporary solution (it tends to get continually worse), so if this fixes it, you should check eBay for a replacement cover.
That said, I had a phone that reset for another reason, which I never found. So it could be something else. I ended up buying a phone with a bad keyboard and doing a keyboard transplant from my old one.
I had the same problem and I'll tell you what I did. Open the back cover and you will see a little black switch next to the sim card/below the battery. I took a pair of needle-nose pliers and just twisted that sucker right out like a bad tooth (carefully though, you don’t want to tear up the foil on the board). Then I put a small spot of solder on the two contacts that the switch used to connect to. Never had a random reboot ever again. From then on, just make sure you take the battery out first before ever messing with the sim/sd card.
That worked for me.
Thanks

i have the very same problem and this sounds like a perfect long term solution.. any chance of getting picture of ur mod for morons like me who need visual stimulation?

LG Bootloop? Only when plugged in? / Battery pull. Pics inside.

I recently flashed Mysteryemotionz v4.1 kernel and about an hour through bench-marking I came back to find my phone rebooting. I assumed it overheated or bugged out during testing and didn't think much of it until it went through the LG logo 3 times.
I noticed it would not turn on at all without the USB plugged in, my first instinct was that the battery became disconnected somehow. I could get to the fast boot and download screens, but any attempt to vol down into CWM was met with failure, and a fresh LG screen over again.
Any combination of buttons that included pressing power would result in the notification LED eventually flashing, approx 10 times. Sometimes slowly for 10x then slightly faster.
It is worth noting the phone would not charge while doing this, but the battery was full prior.
I tried leaving it unplugged overnight, same problem in the morning. Tried leaving it looping all day while at work, no dice. Finally figured I would attempt to see what was with the battery itself. I suppose if you were very patient, you could wait until your battery discharged completely, thus performing a "soft" battery pull, but this will take 4+ weeks at a full charge.
As the other battery pull thread is Sprint specific, here is a refresh for AT&T's LG E970.
I HIGHLY recommend you take a look at nericus' original thread in the Sprint LG Optimus G forum as this is only supplementary.

The tools I used: {{Picture 0}}View attachment 1931288
T-6 Torx bit - Your mileage may vary, 4's and 5's may also work, start big and do not strip your screws.
P00 Phillips screwdriver to remove the battery plate / connector.
Fingernails
Sewing needle or similar
Optional:
Business Cards (the phone has a tendency to re-engage the plastic clips when removing the back, these were used as shims to place in between the case and the phone while working the other sides)
Magnet (not only to hold the screws but you can magnetize your screwdriver / bits which will help when removing and inserting)
Also, for a little preview of what to expect, user Xiutehcuhtli has made a YouTube video, this is also Sprint specific but a good visual reference.

One of the main differences is that your power and volume buttons will NOT fall out, so you won't need to tape them in place.
Be sure to clear them with the back cover when re-installing it.
Also, you will notice that I did not include a spudger as you most likely will not need it.
Our phone is somewhat "inside out" compared to the original article, our back plate is very shallow and our phone is the cradle compared to the Sprint version. This also means there is different risk areas, and pry methods.
{{Picture 1}}View attachment 1931289
Once you have removed the Torx screws, my initial plan of attack was through the SD Card / SIM card cover. You will notice there is a hairline slit toward the volume buttons on the bottom side of the phone, you can very easily trace this with your fingernail and pop the first tab.
Alternatively, you can spread the phone apart gently from the two surfaces revealed by opening the SD/SIM cover and then work your fingernail or a flat object gently into the gap you created.
View attachment 1931290
Patience is key, the last thing you want is to apply too much force to the back cover in any one spot, it is deceptively thin and you risk cracking the glass.
In my personal experience, once I had a few tabs good on the side I simply traced the outline of the back cover toward the top of the phone, across and back down the opposite side, saving the bottom for last. I noticed after two traces around the perimeter of the phone that the back was still very snug and in random spots, as our tabs tend to re-engage themselves much more readily than the Sprint LG.
View attachment 1931291
My solution was to place business cards under the most exposed tabs and gently work it to cover as many tabs as possible and moving along. You shouldn't need more than two, as this can cover an entire side as well as the top and bottom simultaneously, allowing you to focus on the last side. Again, patience and determination will get you there after some time.
{{Picture 4}}View attachment 1931292
I cannot stress enough to come through at the shallowest angle possible when prying the battery cover with the sewing needle or similar tool.
I have highlighted the points of attack in green, be sure to get in between the two plastic pieces, and gently pry them apart.
Do not get under the entire assembly on accident or try to remove with your finger, it will pop the bottom connector off of the motherboard at the solder points leaving you in a bad situation.
After leaving the battery disconnected for about a minute, and then holding power for a good 10 seconds, I reconnected it and attempted to power on. SUCCESS!! - You can test this with the cover off, so don't make double work for yourself by closing it first.
I hope this helps for a few AT&T LG Optimus G specifics.
Attached should be a zip with a few very large originals if you need a better view.

YOU SIR ARE A SAINT> i had the exact problem you detailed here with my at&t LGOG, i LGNPST flashed multiple e970 stock roms, and after pulling my hair straight from the follicle, i went out and grabbed the tools, followed your method here and it worked PERFECTLY! THANK YOU GOOD SIR.
So if I pull the battery, wait a minute or two, hold the power down for ten seconds, and then reconnect and nothing happens, and plugging it into a wall charger shows a red flash, does that mean my battery is actually literally dead?
Edit: Also I would recommend following this dude's guide for his plan of attack: http://bit.ly/10VlQWK
I snapped the little bits along the power button and volume. Not a big deal, only aesthetic.. but its something that is avoidable.
Nice. Any idea what caused the boot loop?
i was struggling with ME kernel and rom for about a month. No matter how i wipe and reflash always had reboot/kernel crash/bootloop issues. ME kernel wouldnt even work with the stock rom for me. Now i just run stock rom and kernel, not many issues so far.

I would disregard 90% of that video because our back comes straight off, this video is not an AT&T Optimus G.
Especially the part where he is prying by the screen. Someone is going to take that literally and destroy their stuff lol.
Anyway. My guess for your question is that you might have ripped the connector off of the board. Check continuity of those pins in the connector and make sure they didn't come off.

Help Fixing GPS - Timmy E86 (mediatek)

My 2nd post with this accound but ive been a member for qutie a while but was inactive for a few years and cant recover my account.
Anyhow i bought a Timmy E86 . Its pretty cheap but pretty good apart from the GPS
It has the mediatek 6582 chip.
Ive been through just about every mediatek gps fix.

When i got the phone GPS signal was non existant. even after using many different gps fix apps.
I then discoverd that without the cover on and the antenna peeled back i managed to get signal, put cover back on and signal goes. So the cover is blocking signal.
I extended the antenna with a make shift foil antenna, which improved the signal slightly and allowed signal with the cover on. Great thinking its fixed, however navigation was terrible, loosing signal and the heading facing wrong way.
Then it lost all signal again after a restart and woukldnt get signal again randomly until smoe while later. Satilites show but zero signal.
The antenna is rubbish on this phone,
I know this is probably the main source of the problem, i plan on remove the case cleaning the contacts and installing a better antenna, either made of copper tape or perhaps something else.
But im pretty sure theres something else wrong deeper down in the software.
I done some further testing yesterday managed to get gps signal and 3d fix. Since i was being a passanger rather than driver i could see what was gong on. as soon as we started moving the satilite signals would drop to 0.....
ni thoughts?

Finally tracked the issue down to really poor GPS antenna.
Remoived it, replaced it with bare copper wire from a power cord , made sure it was well twisted so all the strands were together and neat.
Used the end of the GPS antanna that contacted the board and soldered it to the the pad of the old gps antanne end, so that when the case went back in it contacted the board pin.
Success. GPS lock indoors at a window and still picking up satilites away from window but not enough for lock.
Until i screwed everything back together and tried to put the back on, the cable was too thick and it pushed the board. GPS signal no longer works.
Even tried replacing with thinner cable and solering direct to board but same result. satalites in view but no signal, not even outside now.
Guess ive either burned out the gps somewhere or something on the board got damaged from the cable pushing on it. Even removed the SMD contact pin and soldered wire directly onto the board. Still nothing

Given up on getting this to work. either ive broken something in the gps or the phones setup has went iffy.
Satilites are apparently in view but dont ever get a signal from any, all 12 satalites sit there with zero signal even outdoors.
The easy solution?
Use my old phone that can get a lock inside next to a window as a bluetooth GPS reciever. Using Bluetooth GPS output, and then the bluetooth GPS app on my timmy phone.
Result? Perfect navigation using Tom Tom GO. This is actually a much better solution since the phones GPS is off its using much less power. My old phone is an alcatel one touch which is pretty good for battery even with gps on plus with the screen off doesnt need charged while using it for hours as gps+bluetooth.
Another advantage, i can have a gps app open on old phone for speed and have a GPS speedometer running while navagation running on my larger timmy e86.
My recomendation is just get a bluetooth GPS reciever if your gps sucks.

Xiaomi Redmi Note 3 (SnapDragon) wifi problems

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

No GPS lock despite fixed satellites

Hey guys,
so my G5 locks on to up to 20 satellites with more satellites being visible, but doesn't establish a GPS lock. It will sometimes acquire a lock after 15 minutes or so, but accuracy will be atrocious (300m+). It used to have <10m accuracy with less satellites locked. I did not change anything about my rom or installed software. Is there anything I can try?
Do a Google search for "LG G5 GPS Fix". There are several threads both on XDA and Reddit related to this and how to fix it, but this one should get you started...
https://www.reddit.com/r/lgg5/comments/4u8m9p/how_to_fix_your_gps_fixed_in_10_minutes/
Many commenters noted that bending the pins up only fixed the problem temporarily, that they eventually will lose contact w/ the back plate again. When I fixed mine last week, I put a 2x2mm square shim under the motherboard to keep the pins raised up enough to make good contact. I just cut a corner off a business card, removed the MB screw just above the pins, slid in the shim then replaced the screw. It only raised the MB a hair, but it was enough to keep the leads making contact with the back plate. My GPS has been working great ever since.
If you don't want to tear down your phone and risk voiding the warranty (or cracking the screen), others have said they had good luck sending their phones back for warranty repair. But you'll be w/o a phone for a week or more if you do that.
Thank you. The thing is, I already did that fix and my phone is seeing and gets a fix on plenty of satellites. It just doesn't get decent gps coordinates even with 20+ satellites connected.
So for anyone reading this: What worked for me was to open the phone again and actually use a slightly *thinner* piece of paper than before to raise the Mainboard. Currently seeing +-8m indoors and +-4m outdoors with 20+ SATs in use. No idea if it's going to last, though.
