[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] STEPHEM4:
Was this issue resolved on Samsung's end or did I just happen to luck out?

I ran four tests at different ranges from different rooms of the house with 0 -3 walls of signal interference, this is what came back;

Modem/router used was Motorola SURFboard SGB6580

Range less than 10ft, same room

speedtest.net/my-result/a/1083608841

Range 12-18ft, one wall between myself and router

speedtest.net/my-result/a/1083609917

Range 20-25ft, two walls between myself and router

speedtest.net/my-result/a/1083611441

Range 25-30ft, three walls between myself and router

speedtest.net/my-result/a/1083612485

You're going to have to add the www on all of those manually because I'm new. :P

Have used all kind of roms since I got the tab pro but on all of them WiFi reception is a lot weaker compaired to my HTC m8 and girlfriends HTC one X

2.4 ghz is what is use on n protocol.

For me it's one of the reasons to exploring a new tablet. I use the tablet in my backyard and 2nd floor and it drops regularly.

to bad because all the other specs are awesome!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] otyg:
Wireless N (2Ghz or 5Ghz) is limited to 150 Mbps on this tablet , so you will probably get 11 MB/s Max speed close to the router I tested with iperf (5Ghz , 40Mhz, ch 39 - 20Mhz performed half that rate) , if you have a AC router, then I think you can connect at 350 Mbps (will test when I get an AC router), dunno why the N network is limited as N should be able to handle up to 300 too.. so it must be a limitation of the wifi chip.

btw

-60 - -40 dBm is considered excellent

-80 - -60 dBm is considered good

anything lower then -80 is considered poor, realistically getting anything better then -40dBm is probably not possible unless you live in a cave

Also don't forget the wifi will always be trying to switch to low power modes, so it might show its only connected at 12Mbps but thats just because it has no activity and lowered the antenna power. (or you are really far away :) )

galaxy tab s wifi problem

I had the exact problem with my Galaxy Tab S 8.4 LTE. I've tried everything that's been proposed to many sites.

You don't have to do any of them.

Just type *#0011# and you'll be directed to the service mode.

From the menu, check wifi and you will see "wifi power save mode"" uncheck that and you are ready to surf the net for ever.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] Jonous:
That is if you have the lte version. What about the wifi version, there is no way to get into factory settings this way.

Is there actually a fix?

Hi everyone...

So I got a Tab 8.4 about 2 weeks ago and since that time, I've noticed that the wifi dropping has gotten worse.

I've been reading through lots of posts and trying different tactics (holding it different, changing the wifi settings, forgetting the networks... even tried changing from AC to B\G\N)... but nothing has worked.

I IM'd Samsung tonight and they are recommending a full factory reset. Before I did that though, I have 3 questions for the community.

1) does a factory reset actually fix the problem

2) If I do a full backup (minus wifi settings) via KIES, will that reintroduce the problem when I restore

3) What should I avoid doing\upgrading when I restore to avoid this problem in the future

I'm of the mindset that formatting is a lazy way of fixing a problem... but that sometimes its necessary. I just don't want to start a cycle here. Since I have not rooted my tablet yet, I'm unable to use the normal backup apps... so I'm hoping Kies is actually worth something and not just a piece of garbage when it comes to application files.

Thanks everyone!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] RageAgain:
I have recently purchased a Samsung Galaxy Note Pro 12.2, a Samsung Galaxy Tab Pro 12.2, and a Samsung Galaxy Tab Pro 8.4. Of these, only the Tab 8.4 had wifi issues. Not only did it drop wifi, but it ended up crashing my Comcast Modem/Router. After several reboots of the Comcast unit, I remembered an old fix for wifi problems involving renaming the device. Despite the fact that the auto-naming was the same as my Tab 12.2 and Note 12.2, once I had renamed it to take out spaces and special characters ( just using letters and numbers ) it started working as it should. So basically I went from "John Carter (SM-T320)" to "GalaxyTabPro84". It may sound stupid, but that is what has worked for me.

Oh, it also seems to have increased the speed of my connection as well.

As silly as it sounds I can't believe that worked.. lol..
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] Udonitron:
Bumping an older tread here.

I just got mine and it is on 4.4.2 but my WIFI just keeps turning on and off so I cannot even get onto the web to update it.

From what I have read, someone figured out that SideSync is causing all these issues but you cannot disable it however the issue seemed to be fixed once updated to 5.0.2.

My WIFI will be on and I will choose my router and put the password in but when I hit connect it just freezes for about 5 seconds followed by a "Failed to connect to network" and then the WIFI turns off...3 seconds later it turns back on.

Rinse repeat.

Trying to download the 5.0.2 now...Kies sees my tablet however it does not say there is a Firmware update for it at all and when I choose to search for one, my tablet does not appear in the list so it thinks there is nothing to update.

Really weird
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] Udonitron:
Well the update to 502, while a nice improvement, did nothing for the WIFI issue. :(

[Droid Ultra Q&A, Help & Troubleshooting] Charlierb3:
Hi all!

I rooted my Droid Maxx 4.2.2 successfully using an app I pushed to my phone then ran on my phone (MotoRoot I think, but I get the various MotoRoot, Slap, PwnMotos confused) .

Things were just peachy but I wanted to update to 4.4 while retaining root.

So I went to waynekent 's site page 6 page and the guide in xt1080kk.zip to do this.

Made it successfully through all steps and ended up with "Now your device is on a undefiled, clean install of 4.2.2_12.15.15."

and here I stay.

I cannot seem to get telnet to connect to my phone. Both PC and phone are on same WIFI, USB debugging enabled, verify apps off, firewalls and antivirus off. When I try start telnet as system on 2222 using Cydia Impactor, a "PayLoad" program opens and immediately closes with no chance for me to do anything. Telnet program itself times out.

Trying other methods like installing SlapMyMoto or PwnMymoto..apk via ADB results in a install_parse_FAILED_UNEXPECTED_EXCEPTION error

Unknown if related: My write protection has been disabled.

Any help would be greatly appreciated!
[Droid Ultra Q&A, Help & Troubleshooting] Charlierb3:
Got my telnet sorted out but now when I try the command dalvikvm -cp /sdcard/RockMyMoto.jar RockMyMot

I get the message

device is not write protected

and then it stops there. Any tips?
[Verizon LG G2] topurdue:
I had a problem with my LG G2 Verizon Smartphone. The GPS wouldn't lock on and didn't know which direction I would even be going ( I searched I couldn't find a solution.). I ran into this app and it works, Assisted GPS Injector. It's available in the market and it worked immediately and took care of all the issues I was having. I'm sorry if this has been posted here before, but I just wanted to make sure everybody knew becaue I tried many things to get the gps to work right and none of them worked until I used this app..
[Verizon LG G2] lartmander:
I tried a bunch of attempts at getting my GPS to fix (different roms, editing gps.conf, using various gps apps, etc), but after replacing it 3 times with VZW I got it. Some of the HW is known to crap out for GPS so if you have warranty with VZW, don't hestitate to call and swap devices.
[Verizon LG G2] madkillr05:
I'll try this tommorow, been having problems with my GPS as well, it'll lock but it will be sort of erratic/not accurate and lose signal. I'm on my third replacement device so I really don't wanna have to do all that again..
[Verizon LG G2] Dri94:
Didn't do anything for me
[Verizon LG G2] topurdue:
I have no idea if there's a difference other than ads on the pro or free. I paid the .99 for the app. It worked for me instantly. Clicked on the app then on the gps icon and away I went and it found my exact location immediately and kept locked on the entire trip. I only tried it because I read in the reviews somebody had similar issues with their lg g2 and it worked for them. I'm sorry it didn't work for you. I had downloaded A-GPS Xtra and reset all my previous gps data first. Although that didn't help my situation by itself it could of possibly helped.
[Verizon LG G2] DHM078:
On my first G2, the GPS wasn't great no matter what ROM I used, it didn't even work right out of the box. The replacement I got has been working on literally every every ROM I used. The original didn't work on any firmware release either. I tried many different apps and config files. The one I'm on now is perfect. I guess it's just bad luck sometimes :P I guess if still stock one can always go to Verizon about it
[Verizon LG G2] topurdue:
I didn't have a choice about taking it back to Verizon. I bought it off of CL and it was probably one the original owner had replaced. So, returning it isn't an option for everybody. I tried many things that didn't work also, but this app did and it's why I shared.
[Verizon LG G2] enik_fox:
I've had a similar issue on my sprint version. Doesn't make it unusable but sometimes I will magically be driving on the wrong side of the interstate or of the road backwards. I just hope that it's just a software bug

I bought my Verizon g2 on swappa so I am in the same boat. I don't know what this magic app does but works for me. Thanks for sharing.

Help

Any updates how to fix this?
[Verizon LG G2] cckeeler:
I have been going back and forth with Verizon and the GPS on my G2. I actually have my third replacement phone waiting for me when I get home. The last rep I spoke with said that it is a known issue that is to be fixed with an upcoming update. I would assume that update to be 4.4.2 but I haven't heard whether or not the GPS is any better in the leaked OTA. He did tell me that they have received the update from LG but it was currently being tested.
[Verizon LG G2] Ainvar:
The GPS issue is actually a hardware issue. There is a springy connector on the phone that tries to keep a steady connection to the anttenae strip on the battery cover. It is on the side opposite of the SIM card.

Here is a picture from another XDA thread by JTNiggle that shows the insides of the VZW LG G2.

First picture shows the battery cover and you can see the small square copper connector for the GPS antennae on the right hand side. Second picture shows on the right side of the phone above the battery the little springy copper connector for the GPS sensor on the phone. These are the two areas I used very tiny pieces of electrical tape on to make a solid connection. This has 100% resolved my issue with GPS signals and I have been sporting this change for over a week now. I get a signal lock between 3-7 seconds depending on where I am at (inside or outside) and the days weather. I have done this on a total of 4 phones now and all four phones no longer have GPS signal lock issue. Just make sure you use a non metal tool to pop the battery cover off so it doesn't scratch up the shiny silver bezel strip.

---------- Post added at 09:52 AM ---------- Previous post was at 09:50 AM ----------

I honestly don't think all the software updates in the world would fix this problem. It is a physical hardware issue that is causing the problem.
[Verizon LG G2] forgiven90:
This is great info! Could you clarify just a little what exactly you did with the electrical tape? Like put a tiny piece "under" the flex connector? I haven't actually taken mine apart yet so maybe this would be clearer then... Also is there a chance this would help my compass? I can't seem to get it calibrated and working.
[Verizon LG G2] Ainvar:
On the phone itself there is a small copy flex like connector. If you look on the link that shows the two images for the inside of the phone and the inside of the battery cover, you will see on the phone the tiny little flex connector I am speaking about. With gentle tender care slide some electrical tape (fold it together sticky sides in) underneath the flex connector. This will help it keep a solid connection to the antennae plate on the battery cover. I have done this on 4 phones total one of them mine. All four VZW LG G2 phones had the same issue. Depending on exactly where you were at you would get a weak lock/signal when needing to use GPS on the phone. After this was done the signal is nice and strong and locks within 3-7 seconds for me (yes I have timed it). This is both indoors and outdoors. The G2 is able to lock onto GPS just like any of my other phones in the past and also the MotoX.

I haven't had to modify the GPS.conf from stock (this never worked for me anyways as it wasn't able to acquire a signal 99% of the time). GPS just now works.
[Verizon LG G2] bigsnack:
Will this also fix the issue of showing that I am like 3-4 houses away, while when I was on JB it showed me I was next door(or at least in between next door and my actual location).
[Verizon LG G2] forgiven90:
Well that was an easy mod! I cut a strip of black elec tape about 3/32" x 3/8" and doubled the end to make approx 3/32" of the end doubled. this left a short tab that I could use to manipulate the doubled part under the flex connector and then stick in place to secure it there (or remove later if desired). My GPS and compass are both very responsive and accurate now. I'm also using GPS Status and I've used an app called GPS Injector that I believe help but not as much as this mod. :good:
[Verizon LG G2] Steamer86:
It must be batches, my GPS is about flawless.
[Verizon LG G2] Ainvar:
Yep was easy, I got this idea of course from seeing that image I linked in my previous post and I saw the inside of the phone.
[Verizon LG G2] fsiddique:
Do you mind posting some pictures of how/where you applied the tape? Thanks!
[Verizon LG G2] forgiven90:
I would if I could, but I have plastic/vinyl tape on the back of my phone that in not ready to remove yet :)

Member Ainver posted a link with pix just a few posts up.

I think when you get the back off the phone it will make more sense what has been posted here also.

Good luck :)

[Verizon LG G2] virginwidow:
Thanks for clarification

THANK YOU for clarifying this! I left a note (possibly in the wrong section for) @ xdabbeb's 230 thread asking about GPS but no response as yet. So far the 230(26a) ROM is working fine, so before I do anything I'll back it up :)

I'd like to hear something from users of the current version of my firmware -- is ANYONE getting GPS OK? And if there are 50% or better getting GPS on this vs980 / ROM, then I'd need to look at "hardware problem". It's pretty clear from the photographs I see in this thread what I'll need to address, if possible without breaking it (yes I did see where that happened)

Since the fone was a giveaway to me, I cant return it for warrantee. And I'd like not to destroy it :) I may have to accept that GPS doesn't work, that does seem to be a major problem with these. I didn't get to pick the fone.

I'll proceed when I have more information (from other firmware users) and let y'all know how it goes

Thanks again

I have only run Plain Andy by [MENTION=3419683]Snuzzo[/MENTION] for some time... I have never had GPS issues on his ROMs.

Just make sure you are on the correct radio for your ROM, flashing the incorrect radio could result in no communication for any services or sensor failures (proximity, rotation, GPS, etc)
[Verizon LG G2] virginwidow:
I've "somewhat" fixed GPS. Using the play app GPS Status, following destructions from that app: It said stand near a window, no satellites, so then I tried walking outdoors (my house has a tin roof) -- STILL no satellites. Since the destructions said, "Clear view of the Sky" I walked wayyyy up my driveway, out from under the BARE LIMBS OF TREES.... Suddenly (after restting GPS and etc), I get about 6-7 sats!

Which now locate me within like 80 meters which is fine. HOWEVER -- I have yet to test this in the car (with a metal roof)

Using AndroidTS GPS test, the gps fluctuates sometimes locating me accurately, then jumping to a point about 2 miles from here, then back to "close to" accurate. This seems to indicate the s/w (GPS testing app used) is getting "confused" ?? The accurate locates would have to be coming from satellites? But then it "flops" back to an inaccurated default when satellite signal becomes weak? (I am guessing how it works)

Would this indicate a hardware problem with my device (getting poor satellite signals) obviously GPS *IS* working in the ROM or it'd not work at all. I suspect the intermittent position jumps are HARDWARE for my vs980?

I like the looks of the Plain Andy ROM :) Might jump to that for simplicity sake but going to wait until I'm a little better grounded with ADB/Fastboot. I'd have to drop back from the stock 26A radio/bootloader etc thing and I have a feeling that will be tricky :)
[Verizon LG G2] acejavelin:
If you have TWRP installed its pretty easy, [MENTION=3419683]Snuzzo[/MENTION] has a modified radio ZIP, just flash, reboot to recovery, and flash ROM/Gapps.

Before that try FasterGPS from Play Store, and set your time servers for your region... It can help sometimes.
[Verizon LG G2] dkahs23:
How can you tell if the GPS chip is bad vs. the antenna? The reason I ask this is. Because when I use an app. that calls for the GPS the icon on the status bar comes on but never goes solid white...so it never locks on. I have used all of the different types of apps that are talked about in this thread and others. I have even tried the antenna fix. And nothing is working. A little bit of back ground on the phone is...It was dropped from about waste high, the screen was replaced. And ever since then the GPS hasn't worked. Everything else works great, just not the GPS. I'm trying to figure if its worth sending it off for repair. Or just sell for parts. Thanks for any info or input.
[Verizon LG G2] rnh:
The solution which I take no credit for is purely gps.conf based. I got the attached zip from a post in an xda forum but unfortunately I didn't bookmark it . You can flash the zip if you have a recovery installed or if you know how to replace the gps.conf i system/ etc just extract it from the zip. the lock is fast and the gps track while moving is accurate. It's a Gordon Derek server gps.conf not a samsumg s3 gps.conf.

GPS issues

Try a clean flash of the newest Verizon xxx27 rom.

It still can be rooted with Stump, and it has cured my unreliable GPS.
[Verizon LG G2] chairthrower:
After my 3rd replacement phone and lots of problems, I'm very confident most of the G2 GPS problems are hardware related, somewhere in the antenna harness under the back cover.

I did the thing with the antenna contacts and that did help a little bit on one phone, but subsequent ones had trouble locking on even with that. I replaced my phone a few months ago and the GPS locked on with better than 10 meter resolution, indoors, in seconds. It still generally does that.

If the phone's under warranty just convince them to replace it. They had me do a few things (factory reset, etc.) but they eventually let me replace the phone based on the data from the GPS Status app. If you're not on warranty, it may be worth trying to replace the midframe (the antenna part under the back cover.)

And yet going back to a Jellybean bootstack and compatible ROM fixes the issue 96% of the time.

I am on 24A rooted with Stock rom. Do you think that me on 24A or it rooted would be the issue? I have hardware fix and also tried software app fixes that I did on my old phone with no success. On Sunday I was with my sister and we needed to use my GPS to go somewhere but for like most of the trip is was saying GPS lost. My sister and I have the same phone but here is stock without root as she chooses not to mess with her phone but me I have it root and stock to 24A. Why would hers would without any problems but mine works like crap. Mind you I got my used on swappa.com and it seemed the GPS was working on at the time but did not really notice it not working till recently. I had the phone since Feb. 12, 2015.
[Verizon LG G2] michaelbsheldon:
Yes, the jump from 24A to 26A improved my GPS.

If you haven't already, carefully remove the back cover with plastic implements and your fingernail. No metal.

Locate the little gold contact that makes contact with the cover antenna. Place tiny piece of electrician's tape or

paper to hold it up more than it sits at present. This gives a more solid contact when you replace the cover.

There are several nice tutorials with pics for this surgery floating around in Google Search.

Next, backup everything and flash # 26A or 27A. Install GPS Status and Toolbox app from Play Store.

Am guessing this will perk up your GPS. Mine went from ridiculous to right on all the time with these steps.

I made sure GPS locked fine prior to rooting. Continued to work fine after using Stump. Hope this could work for you.
[Verizon LG G2] Trilback:
The problem is I have a hacked wifi hotspot and was told it does not work on 27A but that is why I am at 24A. I want to use my phone as a wifi hotspot. I have not the hardware part of the fix today.
