NFC Tag Reading and WiFi Calling - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

So my GF has (I'm 99% sure) the L720T (almost positive it's spark, I can double check). I flashed it to Stock Rooted Deodexed NG2 Refitted for her and haven't been able to read NFC tags at all. I can Android Beam from my phone (LG G3) to hers and back, but can NOT detect tags at all. I believe the battery is a the NFC antenna?
Also, it does not seem to have included WiFi calling? I didn't see it in the ROM either (though the activation app shows it's active for the phone). Any way to get the executables for it? (I tried using the ones from the stock ROM, but they just FC).
Also, I couldn't get WiFi working until I changed the kernel out, was very frustrating over all!
Thanks!

Yes, the NFC hardware is built into the battery. I think your problem may stem from the Rom itself, as Refitted is intended for the L720, not the L720T. Could be missing some libraries or whatever that she needs. I recommend flashing the stock rom, or a custom rom that is proven to support the L720T and see if that corrects your problem.
Not sure about Wifi calling - again, could just be an issue of the rom doesn't support the tri-band model. Does wifi calling work for the device on a stock Rom?

[Q] xcover 2 (GT-S7710L) not getting high internet

Hi all!
1. I bought my phone (xcover 2 GT-S7710L) in the states, and when I brought it back with me to Israel, the internet doesn’t work properly. It's very slow, and shows only "G", not 3G, H or H+ like it should. Is there anything that can be done? A new modem?
2. I tried to update it do KK (from JB), and it wouldn't recognize the sim at all. Perhaps it's because I got a rom for S7710 and not S7710L (?) - do you know about a rom that supports the device? I've tried both Vanir and CM11, with no success.
Thanks! Itai
zilmsys have
Did you ever get this figured out? I'm having a similar problem with my GT-S7710L (i'm in the US) after having flashed Rom and recovery for the GT-S7710. Except I have not mobile data at all. I can still text, call, and I have wifi.
nope

The KK rom (for GT-S7710) i've flashed made the phone pretty useless - sim not working at all.. I manged to flash the JB stock rom, and it is back as it used to be - low speed internet, and a working sim card.

Cross ROM Flashing

I am trying to find solid answers on this before I do it, but can't find any evidence it will work, and without issue. I just want to gain my T-Mobile wifi calling, and be able to use IPv6, but the ROM that my Note 3 came with, does not allow any of this (APN protocol is perma-greyed out and of course no wifi calling).
So here's what I have: Mexican N900W8
The ROM I want to flash: N900T for T-Mobile. Stock ROM.
Can I just simply use Odin and just flash it without rooting or anything since both are stock ROMs? Or do I still need to root it?
Also, if it will just flash right over, will my phone identify itself as a N900T and get over the air updates for T-Mobile, or will it ID itself as a N900W8 still, and possibly have future update problems?
Lastly, will all the other hardware work fine without issue? Wifi (most important obviously), NFC, etc?
Thanks.
I tried looking for this kind of cross flash but could not find anything whatsoever concrete that re-assures me this will work.
I would really like an answer for this.
Can I cross flash a stock ROM or not, and in this case N900T to N900W8 without any wifi issues?

You can flash 900T ROMS on the W8, however, not via Odin. Has to be done via Custom Recovery and you still have to flash the W8 kernel for it to work. - Essentially yes, You have to root, but I don't think you can get your T-Mobile WiFi calling unless you have an actual N900T.

As radical said, you can flash it using custom recovery.
It will show up as N900T instead of N900W8, but you can change this using "build prop editor" from the Play Store.
You will not get any OTA from T-mobile, custom ROMs don't get official OTAs.
I went and got a N900T then from T-Mobile. Have a N900W8 for sale now.

[Q] Data Drops During Calls. Please Help.

Hello guys. I have the n900t, I am now running tweaked s5 base n4 style v6.0. And I run alot of n9005 ROMS as well. With that said here is my issue. For only the past few weeks ( month tops) every time i make or recieve a phone call my data drips down to hspa. The second i hit call and right before my phone rings is when it happens. After my call the data takes a very long time to jump back up. This is a new issue and i have no idea what it is. However, i did flash back to a stock ROM and the issue was solved. And i forget which rom it was but it was soley TE based and there were no issues. I did try to flash a modem but it didnt take. Is anyone else experiencing this problem? Or can anyone suggest a fix for it.
Thank you for your help.
bump.
Still having the issue. I tried to flash a new modem and it just failed anyway. Dont know if I should try a radio. I just cant fivure out why this happened out of no where. I was fine no matter what ROM I was running. Now...this crap. Please guys, 40 people saw this, can SOMEBODY please help.

1) Quite strange - your picture suggests you are on Verizon yet you comment about a N900T in the forum for the INTERNATIONAL Note 3. On what network are you? Are you aware that there might be network-specific factors involved which could only be visible for other users on exactly the same network in exactly the same region?
2) Try stock ROM (with corresponding stock modem) from a location with very good signal.
5 he physical device is an n900t, however, I am running as of now, the hyper drive note 5 port with n4 UI. When I do flash back to a full stock TW ROM all is good, A FEW TW based ROMs seem to be OK. Like this one, the calls do not affect the data signal. But most ROMs do effect it in that way. You said that it shows I'm running Verizon?
But I am very curious why all of the sudden I am having this issue. I have never had it before. Except with a few specific AOSP based ROMs. I just can't figure out what it is that's causing it. I have done vigorous wipes of the phone to no avail.
And I am in Philadelphia so there really is no place that is actually bad reception (except in the susubways of course...lol)
And thank you for your reply.

1) Your avatar mentions Verizon for some reason.
2) If it is all OK with the stock ROM then it is a problem with the custom ROM, ask in the specific thread for that specific ROM. Most likely it has something to do with the modem and the corresponding RIL.
So when ever a new ROM is flashed the modem is flashed as well. Unless the dev says otherwise?

SVA ROM v10 - problem - can't find location

Hey guys, a few days ago I bought from ebay a used I9502. It came with SVA rom with android lolipop 5.0.1 preinstalled. I like the rom very much but i have a major issue. It is impossible to find my location using only wireless networks (wifi, 3g)(power saving mode). It can only find my location when using GPS and I am outdoors (high accuracy mode). I have tried to reset to factory but nothing changes.
Do you know what may cause this issue?
Thank you.
update
I have an update for those who might be interested.
I flashed the latest stock rom from sammobile to see if the problem continues. With the stock rom the location servicve works fine.
After a reseach I figured out that the SVA rom is missing "NetworkLocation" that's why it wont find my location using wireless networks.
The problem is that I discovered that the version of "NetworkLocation" I have, collects and sends data to Baidu(something like the chinese google). So I was wondering if any of you guys using an international lollipop Galaxy S4 would like to help me and send me his version of "NetworkLocations".

G928G + Wi-Fi calling (MetroPCS) help

I got a G928G off monoprice and it seems to work fine, M update was waiting when I powered on and everything. We are switching to MetroPCS/T-Mobile but the problem is, we get 1 bar of LTE inside the house and can't make/receive calls. Wi-Fi calling would be the answer but it isn't available in the settings anywhere. I know MetroPCS offers Wi-Fi calling and through searching it appears it is available on other FWs for the GS6E+ but not the stock one for G928G. I would prefer to keep the stock FW but I'm OK w/ rooting if I can get this added. Guessing a new bootloader won't change this so I'm afraid I will need a new ROM but I would at least like it to be a stock Samsung one. Found something about "Aroma" here but not exactly sure how this works.
Can someone point me to one that will work on the G928G and includes Wi-Fi calling? (Also, any recommendations on the best process for rooting/flashing for Samsung would be appreciated - I have rooted a Note 3 in the past and some other devices but not flashed a custom ROM - is this procedure good if I find a stock ROM that supports Wi-Fi calling?
