So in one room in second floor there is 1 bar wifi. My i9195 disconnects after sometimes and have to wait until it connects while others have no problems. With other phones (s2, lg 70.....) it don't disconnect and everything perfect. Even they can brows in third floor and for me no chance to connect wifi and browse etc. Is this problem with phone or this phone has bad anttena? If someone has same problem with i9190 please respond is everything Ok.

I recently got S4 Mini i9195, and noticed same problem, wifi was absolutely poor. I started searching on the internet, found where the antenna is, and decided to take my device apart. And you wouldn´t believe what I found.... all other antenna contacts on motherboard are bent, they are in a ˂ shape - so they can flex and touch antennas integrated in middle frame chassis. Wifi antenna contact was absolutely straight, parallel with the MB, so there was no way it can touch antenna on the chassis. I used needle and carefully bent the contact in correct shape, assembled phone and voila - wifi signal is full.
It seems it was a production error, I´m surprised nobody noticed it before.

Hi,
I am not sure but after my phone fell from 50cm table! my phone always shows "no service".
I changed my SIM card and flight on/off mode. It didn't work.
The other phones sees the signals but mine doesn't.
Yesterday I recognized that if I am very very near to the link of the service provider (say 100m) I have signal! and can connect.
I think my antenna has vey poor performance. Do you have any idea to fix it?
Thanks in advance.

Same problem! It randomly lost service signal, and now I am missing signal everywhere except in a big city, but even there I mostly don't have signal. I have tested this with 3 other friends who have the same service provider and have 3 out of 4 bars - while I have 0.
I lose signal when the phone is in my pocket, when holding it below a table/desk (in school), when holding it wrong in my hands. It's a really annoying problem and I'll send my phone back today.
Try squeezing the phone a bit, maybe it slided around inside the case a bit and lost the connection to the antenna
Sounds strange but fixed my Wi-Fi temporally (at the end I bend up the antennas a bit...)

That only works with Wifi, but the wifi issue is already fixed on my phone.
So my note 2 has really really weak wifi signal, I am 20 ft from the router with only 1 wall between us and the wifi keeps timing out and sputtering.
I have turned off the power saving wifi and replaced the drivers with the ones from 4.1.1, I have tried numerous kernel and roms.
Is it time to open up the phone to look for a hardware fault?
Also screen sensitivity on the bottom right of the screen is terrible, trying to hit the back space key can be a nightmare at times

Found the wifi fix
I just figured out what the problem is, the wifi antennae in the case was buggered! I ordered a new back of the phone and replaced that and the wifi is fixed!!! I had a feeling that was the cause of the issue but I couldn't be sure till I replaced it. The wifi antennae is above the power button, with the back off you can see it as the long piece of plastic that is stuck in on the very edge. I had to buy a whole new back - it was only about $11 shipped. But it solved all my wifi problems.

I took the main part out of the chassis frame and found that the spring contact on the PCB (which is supposed to touch the wifi antenna on the chassis frame) wasn't springing up. I bent it up so it matched the profile of the other spring contacts and put it back in the chassis frame and all was well. My suspicion is your wifi antenna wasn't broken (it's just a bit of metal so there's nothing to break, really), just not quite touching the spring contact.
Same Problem

Good day I am assuming that this is the same thing that has happened to my note 2 it had a fall, everything else is working fine just the wifi signal drops when I step a couple feet away from the router so can I ask for a link of where I can purchase the same part you are speaking of or a picture of where the spring contact is so I can try just bending it up please
Yeah mate when my wife comes home with her phone I will be able to take some pics of my phone and post them up

I,m experiencing the exact same problem. Wifi signal has gone extremely weak after a severe fall. Can u please tell me exactly which part to change.
Post a picture, or an amazon link to buy that part?
any help would be appreciated.
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.
Sent from my LG-E980 using Tapatalk
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!
Hello. Recently, I opened the back cover of my note a couple of time to reattach the loose LCD ribbon in my tablet. During this time, Isomehow,noticed that the wifi was not working! Well, it was working, but I cant use my device unless im < 10 feet away from a router. However before, it was working perfectly fine, and on my other.devices, everything is fine. Is this a well known problem? Did I damge the internet card in my tablet? Also, the signal is around -60 when im close b
ut when.I walk 10 feet away it is like -90.
I would imagine you have disturbed the Wifi antenna. I haven't seen inside the tablet, but it would more than likely have at least one antenna connected to the Wifi module.
It's usually a thin wire running on the outer frame.

My tablet can not see my wifi router when it suddenly shutdown.
I don't know why my tablet never see name of my wifi router if suddenly turnoff wifi router. I used WP2 and AES & TSKIP.
And if want my tablet P600 see my rounter wifi, i must go to wifi router setting to change AES or TSKIP and then my tablet can see it. But my galaxy s4 don't have this problem. Maybe kernel of galaxy note?
Hello guys
Is just me or anyone here is having weak wifi signal even when I am near the router while other phones not having this issue!!
Ps: it's only my second day after buying the phone

Sorry To Read You Received A Faulty Device.. :angel:
There Are Zero Wi-Fi Issues With The A70 On A Mass Level.
You Should Begin The Process Of Obtaining A New Replacement Unit A.S.A.P.
Mine drops frequently to the point that it's frustrating. Check out my post about the screen and tell me if you have the same issues too. We might have the same versions of the device, which appear to be a bunch of faulty versions from the same batch.
I'm having an issue as well. My old phone can and able to detect and connect to my WiFi (which is quite distant tho) meanwhile my A70 can't, I have to get closer to the Wi-Fi in order for it to detect/connect to it but after that if I return to the other place when it doesn't pick it up, I'm able to maintain the connection. It's weird..
Use 3rd party app to connect on wifi. Im using wifi master. Playstore have it

Here you go buddy
That Wifi Master app is unsupported by the A70 so I don't know why you'd recommend it here
wifi is definitely one of the worst thing on the a70...it drives me up the wall, and i am ready to sell my phone and never touch any samsung anymore because of this...i am not sure, but samsung is trying too hard to make some things "smarter" meaning if samsung thinks your wifi signal is bad it drops connection just like that...exclamation mark, lost connection, switch to data, are countless through the day...and samsung is playing dumb about this problem...
my wife is using lg and meizu on the same network and wifi is working perfectly fine 24/7...
same here. my friend is able to get a stable connection on the same network with a much older phone. However samsung won't do anything about it.

As my A70 also has weak wifi issue.
Can't see the wifi router downstairs when my old. Samsung note 4 can, laptop can
I'm having the same issue. Weak Wi-Fi signal in my A70. While my other phones are getting full signal. Is there any way to fix?
seems like some antenna problem. you can probably fix it by bridging antenna contacts with the pins on the motherboard with a lump of copper wire. Solder can also help.
to take itapart:
1) insert a thin piece of plastic( like a flexible plastic file) into the gap between the rear plastic and frame, and cut the adhesive, and peel away the rear plastic
2) remove the screws and sim tray
3)slide your finger nail into the gap between the rough plastic and the smooth plastic on the side rails. The rough plastic is the part that is touching the screen, and the smooth plastic is the side rails. The smooth plastic is of a different colour, and the rough plastic is black.
4 pull the side rails away, and examine the copper antenna contacts. you might want to replace the mid frame. If you still have warranty, bring it back to store
