Hello people of XDA,
I just bought a brad new S7 edge SM-935F and NFC does not seem to work. I tried transferring profile(using nfc) from my old S6 when i first boot the phone, i tried transferring photos and reading nfc cards, none working.
This happened both before and after the upgrade to Nougat
The enable/disable function does work both for nfc and android beam.
Any suggestions that does not involve taking the phone to service ?
Please let me know

A friend of mine who works at Samsung gave me an S5 Mini (Samsung SM-G800X). He told me its only good for browsing, it doesn’t have the necessary hardware to use as a phone. It also came with Samsung Retail mode enabled. I’m wondering if it really is the case, that it doesn’t have the right hardware or could it be that I just need to flash it with the right firmware?
The Build Number was KOT49H.G800XXXU1ANG1_LLK
Android 4.4.2
I used the Phone INFO Samsung app and got following Info:
Hardware/Board: Universal3470
Platform/Chip: exynos3/xynos3470
Modem Board: SS222
Hardware Revision: Not Active
I managed to remove Samsung Retail Mode and flashed it with the closest Firmware I could find
G800FXXU1ANL1_G800FBTU1ANJ1_BTU
Before flashing there was not even a Mobile Network option under Network Connections. After I flashed it the option for Mobile networks is there.
But as before the phone will not connect/find a network with a working sim inserted. I know that the sim card slot works, because without a sim card it gives an message ‘No SIM’, this disappears as soon as it’s inserted.
Have I got it wrong, it really doesn’t have the hardware? It seems weird that the Modem Board is reported. Is there anything else I could try? Thanks
My knowledge is that models designated 900X do NOT have the radios to make a mobile connection, but CAN be used as WiFi only devices, so for instance Google voice will give you full functionality, but you'll need to be connected to WiFi at all times.

Ok, thanks for the Info
Hey guys, first time post here so apologies if this isn't formatted in a specific way which is the norm here.
I'm having an issue with my S7 running 6.0.1 and build number MMB29M.G930AUCS2APC2 being able to cast to my Chromecast2. I've gone through all of the troubleshooting steps I can think of and have not been able to duplicate this issue on any of my other android devices (Nexus tablet, S6 Edge, Chrome browser casting). The issue being that when I attempt to connect my phone through netflix/plex/hulu/youtube (any integrated casting app) the Icon will change to the connecting state but will never establish a connection allowing me to play the selected media. As mentioned above I've been unable to reproduce this issue on any of my other devices and am thinking it's isolated to either the phone or 6.0.1 (S6 Edge is on 5.1.1). Anyone else having these issues?
The only way i've been able to resolve this issue is to factory reset my Chromecast2 and set it back up on the network, at which point the S7 is able to cast to that TV.
Hi guys,
Been into android modification since 7 years but gave up since my last 2 phones. So i got this unlocked at&t galaxy s7 in uae and it worked like charm, the network and coverage. I then started usingthe phone in pakistan too and it worked well even here. So one day i connected to gear vr so that i can initiate the oculus data installation as first time setup but the gear vr kept on disconnecting automatically. I have used it before too but never had problem. Then i rebooted the phone and i find that i have no signals at all even though my sim contacts are being displayed and there is no “no sim” message on statusbar even. But dont have any signals at all. I then inserted my sim to iphone and it was working perfect. Then i inserted different carriers sims to s7 but yet they werent working even. I then cleared the cache, factory reset, cleaned the sim slot and the sim , but no success. I left ky ohone turned off for days andeven drained battery 100% many times to calibrate and perform hardware reset but no success. I then sent the phone back to uae for repairing from my friend as i thought that the antennae were the one’s responsible but before he even thought of disassembling the ohone, he inserted uae sim and it worked perfectly. Call and data were working perfectly. Any idea what is the problem? Kindly let me know pleaseeee. Is there any problem with frequency? Like gsm or cdma? But the phone worked before. I tried to enter the settings of manually selecting networks but there was error popup “No service and signal”. Signal strength 0asu -113dvm

Forgot to tell, my phone has never been rooted, i even tried to enable/disable “Enable hd LTE features” but no luck. Its on 7.0. Dont recieve OTA. Not blacklisted either. Pakistan doesnt have CDMA. I have even noticed it recieving weak signals compared to my iphone when the phone was working ok. And my radio is showing to be off and when i turn it on from the dial code menu. It doesnt keep turned on and it turns off automatically. I still have the imei amd baseband version. Dunno what the issue is.
Kindly reply guys
Please help

Manually enter your carriers information you'll have to ask them or look it up online sure its easy to find they might even help you in store
Its not good for you to buy these US phones outside of the US because changing CSC to INS/INU/PAK could prove to be difficult being it was never supported by snapdragon G930A model but only exynos G930F although it's not impossible
/system/csc/others.xml is where your answers are waiting for you unless you update to oreo then it'll be in /system/omc/cscfeature.xml and cscfeature_network.xml
You will need a root file manger to be able to see what I'm talking about then you will have to figure out what those "strings" mean
Unless you want to mod and figure out make your phone awesome just flash other US firmware that uses gsm network only i think ATT only uses gsm and you can root to debloat ect.
Here's a method for rooting
https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616/amp/
I'm sure there's people in your surrounding area that are into androids and rooting that understand and can help you figure things out if you know any one woth a G930F/G935F INS/INU/PAK thatd be awesome. If your imei number is truly gone from your phone its should still be on the back of the phone
I know this isn't the best help but you aren't the first post I've seen of Pakistanian with US S7 tryjng to figure it out.. idk if he ever did but if you learn you can help others as well
*note: when I say change csc I don't mean flashing firmware in odin, that is impossible. I mean porting it yourself with root like in the link below this one
*another note: I am not saying use the link below as anything other than an example because again that link was developed for Eynos phones and not your snapdragon so it probably wouldn't work but just so you have an idea of csc

Hey Guys, came here for some help.
My P Smart just stopped reading NFC cards, whenever I put any card on it it just says:
Sorry, this nfc tag is empty. To write on it. download NFC tag write from an aplication store.
NEver happened to me, I do have a nfc reading app and now I cant put money on my Leap card, any help would be great.
Backstory: My sister bought Samsung Galaxy S8. She lives in Canada and after using it for a while, she sent it to me. I live in India and i factory resetted the phone, put my jio sim in and to my surprise it didn't work.
So my problem is, how do I make my sim work with this phone.
Model name: SM-950W
Android version: 9.0
CSC: KDO
No root
Things I have tried:
- restarting with sim in it
- turning on and off VoLTE option
- changing bands with some makeshift methods
- installing jioPhone application (this worked, but it is very messy as I need to have my mobile data turned on, and I can't use my Wi-Fi with it. So that's a major issue)
Please someone find a solution because I really can't make do without it ;-;
