i have a simple question (i think).
what is the maximal distance to a NFC reader device to get the signal ?
thanks.

I've heard that it's round 4 in but I highly doubt that. I've only ever been able to get it to work by actually touching the devices together.

unfortunately i was able to get the signal only buy touching too.
It would depend on the reader, Ive had something work from a good 10cm away

The NFC chip in an Android phone is usually in the battery right? I would think that they would make them low power and compact, as to get as much space out of the battery as they can, which would mean that unfortunately, they would have a shorter than average range, right?
It seems counter productive to put such an important chip in the battery, but according to Samsung it is located in the battery and the maximum distance is 20 cm to allow through cases but short enough to provide security from would be data thieves

Theoretically a scanner can read a chip up to 10cm away, though realistically it's more likelly gonna require a maximum distance of 4cm.
from my experience, not more than 5 cm.
In my experience, with phones and those HID security card readers, the distance is almost nothing. With phones, about 3 - 5 cm, and with HID cards, about half an inch.

does anyone here have one and if so, which brand do you use?
Are you talking about those things you stick on the phone to reduce radiation? Those things are a joke. Nothing you stick on your phone is going to reduce or block radiation to any significant degree. And if it did, it would also affect your phone reception. Remember, cell phone radiation goes right through buildings, trees, cars, etc. A little sticker isn't going to block it.
Those things are just like the stickers that are supposed to amplify your cell signal for better reception. They do nothing, and are just a waste of money. In fact, I wouldn't be surprised if they were the same product, just sold in a different package.
If you want to reduce your exposure, buy a phone with a low SAR, minimize your use, and keep the phone as far away from your body as is practical when not in use.
Just wanted to second that. The information posted is 100% correct.

That can't happen with me. I need my phone with me most of the time. Don't worry - You'll find me in a few years. I'll be the only person on earth glowing green
lol, thanks guys.
I just got worried bc i will be carrying around 2 tp2' now instead of one S) and on one, I will have data running constantly.
Get a bluetooth headseat and keep the phone just within range of it

yep... Bluetooth headset and keep it in your pocket... that way the radiation isn't going to your brain but to your crotch!
PHONE DO NOT WORK THIS WAY!
Mobile phones use non-ionizing microwave radiation and you will NOT get cancer from them.
Hi everyone
I have this problem:
http://www.youtube.com/watch?v=2Gu9oKlWq1Y
Anyone know how to solve this problem ?
Just as a disclaimer, every phone will lose signal if you grip it a certain way. Remember the iphone debacle?
But the quick fix is to just put a case on it. Your body will no longer interfere with the antenna and your phone will have the added bonus of surviving a fall.

Downside is cases tarnish the natural beauty of the phone that the cell phone manufacturers intended. I just take the risk. I would rather have a nice looking phone IMHO.
I already have this one http://www.otterbox.com/HTC-G2-/-HT...C4-G2XXX_color=20&start=1&cgid=desire-z-cases
gripping ANY phone tightly/awkwardly over the antenna will cause loss of signal. Some are worse than others, but it happens to any modern phone with an internal antenna. Cases help, but you're still going to be able to replicate it if you try hard enough. The phones are designed so that the antenna will more than likely not be blocked if you're holding it in any normal conventional way during regular use.
One usual culprit for the G2/DZ is the WiFi signal getting weaker when using the hardware keyboard, because your hands are covering the top and bottom of the device.
so isn't any idea to solve or help a little with this problem ?

Like I just said, there's nothing you can do other than just don't hold the phone in such a ridiculous way. You can't move the antenna inside the phone, it is where it is.
In normal use I highly doubt you'll ever see drastic signal drop because of the way you hold your phone. Nobody normally holds a phone in the way shown in the video.

like I said, using the phone normally (yes even playing games in landscape) your signal shouldn't drop so low that you will be completely disconnected from the network. Don't get scared just because the bars drop.
But i already play at Order and Chaos and this game are also in landscape mode and unhappily i get lost connection every few minutes ;/ and the game has reconnecting.

There's nothing I can tell you. The antenna is where it is. If for some reason you're in a low signal area to start and you cover the antenna you're going to see loss of signal.

You're not listening. Every phone has this issue if you hold it in the right place. Its a cell phone with an antenna. Its just going to happen, there's nothing you or the manufacturer can do to "fix" it after the phone has been made.
I acutally thought this was a radio problem. I switched radios and noticed a slight improvement.

A radio update can help your signal a bit overall, but it will never remove the effect of strategically covering the physical antenna. What it would help with is a default low signal, that gets worsened to the point of disconnection from the network by covering the antenna (aka your normal signal could be higher, so that when it gets lessened it still stays connected).
When testing nfc my phone must actually touch my credit card to register the tag.
Even then it sometimes will take a few seconds or require me to move up and down the card to register.
Is this normal or is my antenna weak? Been having trouble at stores with using Google wallet lately also.

Even with a fairly thick case on my phone, Google wallet works for me on the first try every time, but I always touch the pay pass pad with my phone. I use it daily at gas pumps and vending machines at my college and I switch out between 5 different cases on a daily basis.
Do you have another battery you can try? I've never tested my standard battery. I use the extended with my VZ CDMA Nexus.
I'm using extended GSM battery (OEM). It was about the same on the standard battery.

It is not normal. My first gnex had this issue. My second does not. You still have to touch, but not find the 'sweet spot'.
It isn't the antenna in the battery either. I tried switching batteries with the same issue.
Conflicting reports in regards to NFC on the higher-end Deluxe models. GSM Arena reports it's available, PDAdb, which i believe is more reliable doesn't even mention 'NFC'.
I believe this VERY common feature has been 'avoided' in this phone, absolutely foolish by ASUS as it's keeping me away from this phone. Can someone please confirm? Anyone know why this decision was made despite the fact they have the 5.5", 5.7" deluxe variants and the ULTRA, which isn't much better?
Thanks

It is available BUT it is in the very top of the phone.
Most phones use the battery and have NFC centered around the middle of the back. The ASUS Zenfone 3 deluxe, and the ZTE Axon 7, have it at the top of the phone, around where the speaker is located.
I don't know WHY it was put there but I eventually found it with a bit of hair pulling...
Somethings need to be the top part of the back but you can also use the very top of the phone too. A little annoying as this isn't very well explained...
NFC sensor is on the front near the top of the screen.
Yes, it have NFC, in te top of the phone near the call's speaker
I used it all days with some nfc tags.
An awkward location to put the NFC. You cannot see the screen when it is contacting the other device.

Hey, so I sometimes get the NFC to work (unlike my zenfone 2) bit when I tap to send / beam a picture it goes to Google play and tries to install the gallery app. Anyone know how to send the picture instead?

I get NCF to work.. Did not realize the chip was in a different location than model 2. Model 2 is rooted and can send pics via beam with no problem. Version 3 when I try to beam tries to install the app. Don't need wise ass comments. Joined XDA for "real" advice. If I need bull**** comments, remarks, etc I would have just posted on ****ty websites. Real question for real answers. If you have nothing else to do shut the **** up
The NFC is located at the top of the phone. You could "image" it's using the 3.5mm jack as the center of antenna. (Although it's actually there..)
I use the NFC function almost daily for payment (for convenience store purchase as well as subway ride) and it works 100% of time. (never second time touch) The way I use it is screen facing me, only the very top of phone (basically where the 3.5mm jack is located) is touching the payment terminal reception pad.
Most of the payment terminal will even accept the phone lying flat, LCD up as long as the 3.5mm jack is located near center of the payment terminal's reception pad.
The reason why NFC is located at top of phone is that the back of this phone is made by one piece of metal. NFC signal will have trouble pass this metal barrier. Beside, I found it's easier to use as NFC is at top since can hold the phone 45 degrees (LCD facing me) instead stick the back of the phone flat to the payment terminal when making payment.
Also, the screen is not needed to be on when making payment (YMMV, may depend on APP). The sensitivity of NFC is even better then my cashless credit card. (I tested both at same terminal).

Thanks for the info. One of the downsides of the body design I guess... Good to see its working for you and there's a way around it. I would've gone for this phone had root been available on it by now. Lack of IR is something I don't use all the time, but still find it important and am using on my V20...

Can anyone explain how this is a feature? I mean it doesn't bother me. But the more I think about it . The less it feels like a feature. And more it feels like something fishy. I don't know enough about stuff to understand access to data under a proprietary feature. But at the bare minimum I've never thought you know what this phone needs is that small crappy front facing camera to be in the display . I think I prefer it not there at all since the phone opens the back camera is sufficient for both. End of the day I believe this will be my last samsung. I hate the front screen and inside screen is cool and impressive but still kinda annoying. In my mind these devices should come with all the quirks ironed out. I still enjoy my note 3 rooted as much if not more. And the note 20 ultra was a solid device but wasn't a big upgrade from my 10+. Bare minimum samsung not including accessories is just lame. I would have probably made the closed screen slightly larger for easier use on the go and then the use on the inside screen for less often use in casual settings.
Just my thoughts a month in and was curious to hear others thoughts. I know it's probably and amazing device for someone who doesn't upgrade frequently but as someone who does it was probably the device that has ended my desire for new and cool over tested and true. .
Anyone stumble across any lesser known features or functions that aren't well known?
Customization wise:
I use wavelet and my bose in car sounds amazing.
And have good lock/nice lock until hex is functional again.
Ad block
and system ui tuner that doesn't seem to be adding much
and I tried to see if I could use adb and 3c but it doesn't seem to improve much or increase any functional use but I just had it long ago and thought I'd see if it was useful
The latest update has improved my mobile service in rural areas near by sprint on tmobile experience
I haven't debloated because honestly the device probably wouldn't improve much with less and I'm kinda waiting to understand what all is needed until my account is fully tmobile. I assume nothing they have changes much but since it can't currently be unlocked on tmobile side I'm curious to how it's locked since it's not supposed to be sprint sim compatible. But still has the sprint unlock uicdd on device hidden with tmobile unlock visible. I also hope someone comes out with a case that has a tiny bluetooth keyboard , I think that would be kinda cool.
Ok
I know that for everyone, no device is perfect. As much as I LOVE this Fold 3, it's not perfect, but it's about as close as a mobile device has come for me. Then again, I know that I am also an edge-case as I use my Fold 3 in a way that most others do not. I use it as a Mobile Office. I call it my 3-pocket-laptop (look on YT for a video titled 4 pocket laptop to see what I am getting at).
I have a foldable BT KB with Trackpad, folding Tablet Stand and a 20kMah battery pack I take along and I can literally work from anywhere I have signal. I even made a portable, battery powered monitor (from an old Laptop and some parts I had to order (controller and the like)) I made that I can stuff in a backpack and have an even better experience when on the go. I no longer need to carry my work laptop with me with this setup.
So yeah, I get why it may not work for you, but for me, I love it.
