Could Samsung Galaxy R (i9103) have hidden NFC capability? Photo inside.

According to the phone specs, it doesn't support NFC.
But there are two metal contacts in the back, near the battery, that connect to the back cover.
Removing the back cover doesn't seem to affect gsm, wifi, bluetooth or gps reception.
So I am wondering if it could be some hidden NFC support and whether there is a way to test it.

Doesn't seem...If there would be NFC support in the device, then Samsung would surely reveal that feature when the phone was launched..because it will directly increase their sales. But they didn't..no chance for NFC..

Seems to NOT be the case....
List of NFC-Phones
Would be neat if there's a possibility to get it, some how....

Yes, I know about the specs, but what about my photos? What could these metal contacts to the back cover be?
The kernel source (released from Samsung) hasn't any NFC driver related code apart from the chipset's support for NFC chips.
In the ROM there is firmware for the PN544 (the NFC chip of Nexus S) but libnfc.so is missing. I tried copying it just in case from a Nexus S 2.3.4 ROM but it didn't work of course.
Since some i9103s are supposed to be NFC enabled, I guess it may just be that part of the NFC hardware is there because differentiation in some parts would make for bigger manufacturing costs but some other parts (like the actual NFC chip) are missing.
I still hope though!

May be NFC not annonced cause it ICS feature, so it will be revealed later, when galaxy royal will be upgrated to ICS. For now they dont actually need to increase 9103 sales, they want to sell galaxy II as much as possible first. IMHO.

BTW, look at the bottom of the page in "Additional_Features".

until now it seems to be so

Your metallic pins are used for inductive charging pads (usually stick inside back of the case or over the battery).

^^^ is right... Galaxy s3 has it too... It's for wireless charging.... I think the methods to add wireless charging (using the palm pixie back cover) to s3 even works for this...

Data Speed and Connectivity Issues - test of holding positions

I have been EXTREMELY disappointed in the data speed and connectivity of my new HTC One M8 on Verizon. The phone was having difficulty where my previous phone (HTC Thunderbolt... yes I used it for 3 years) was working fine.
This evening I conducted a test holding the phone differently:

test time
1 1:33 Phone sitting on desk
2 1:35 Phone held in left hand in palm with finger touching both sides
3 1:35 Phone placed back on desk to repeat desk test... test did not complete.
4 1:37 Phone held with 2 thumbs and fingers at bottom and held up (new server after restarting the app after the previous test failure)
5 1:40 Phone sitting on desk
My phone is NOT in a case and does NOT have a bumper. I will repeat the test when I get a case.
This is only a single set of data and should be tried by others and at other times of day etc.
For those of you experiencing data issues -- do you use a cover or bumper?
For those NOT experiencing data issues -- do you use a cover or bumper?

If you're having problems then you probably have a defective phone. Just replace it at Verizon.

I appreciate your reply.
I did another test with a phone case around my HTC.
with case on Desk 12.25M up 5.56M down 57 ping
with case in hand 10.05M up 3.57M down 51 ping
with case in hand 10.07M up 3.45M down 81 ping
with case on desk 12.61M up 3.55M down 69 ping
without case in hand connection failure
The case helped a lot. There are admittedly many variables out of my control.
Would you still recommend replacement for a unit that worked fine with a case but poorly without one?

I've been getting poor speeds with my M8 when my Thunderbolt was fine, but I've figured out it's only on certain towers. An example: .6-5.5 down at home, 55-65 down at my brother's. Try testing distant locations as well.

Those speeds are average for semi weak signal areas. Depending on your city, the tower layout may not be very dense and more spread out. My city is decent size but spread out and has a few large traffic areas which have aws working. My house pulls 2-5mbps, I get 15-20 at work, while at my friends house I'll get 80-100+ down ( aws obviously). It just really depends on the signal strength and traffic on the tower. You could have a bad phone but I doubt it

[Q] [Help] Query about a Display problem

I just got myself a XIaomi mi3
everything was fine i but two days into use I find myself at the eng of a nagging problem..
the bottom edge of the screen is dim compared to other edges , this is apparent mostly when you are viewing white pages.and the top edge is slightly brighter..im not sure whether i can say it is backlight bleed or not..but when i loaded a full screen black page..there was a bit more light coming out of top and bit less
MY question is this a problem worth replacing the phone..? i can live with this as its not much of a deal breaker for daily use..you dont notice it often
Does it have any impications on the life of LCD , battery life etc?
Here are some pics i tried ,but the camera is poor and i dont think i was really able to capture the issue ..but i you look closely you can see the difference between top and bottom edges [top is left side btw]

no way i would "live" with any problem like that on a phone i just bought. if nothing other than being annoyed it doesnt look like it should, i would be worried constantly that it will get worse or spread.
if it were mine, it would have gone back the second i noticed that.

yeah thanx for the reply man ,which is exactly what im doing..hoping the new device doesnt have issues

Display bleed issue

Does replacement Mi3 have bleeding issue too?

Seems it's a bit common, the replacement does have it but compared to the original one it's far less
You will notice it if you look for it., using the phone for over 2 months
No problems otherwise

[Q] Antenna signal

I know the phone is still not in the hands of everyday usage. But im worried about the antenna signal, particularly with LTE, I have the m7 now and in my house i get lte as long as im not holding my phone. This is partly due to metal framing of the phone and im worried if i chose the s6 im going to have similar issues.
Im really hoping that the metal design on the new phone does not impact lte signal significantly. I need fast lte at home since i dont have internet at the house. Does anyone know any specfics on methods or design that should hopefully let this phone have great signal

The phone doesn't have a metal back like the htc phones, it has a metal frame with a colored glass back.

I was referring to the rumor that samsung is ultrasonically welding the antenna to the chassis. Obviously its not a metal back i know the difference between metal and glass fortunately!
Do we know for sure if the lte modem will be ultrasonically welded to the chassis or is it just going to sit under the glass?

So I just found this which is concerning, looks like m9 shows better rf signals for lte bands . I hope this phone doesn't have modem and signal issues
s4gru.com/index.php?/blog/1/entry-3...rock-out-with-their-flagships-for-the-season/

So the M9 has way better signal... Wonder how this plays out in the real world. This does worry me though I frequent places with low (almost non-existant) signal coverage...

Yea which is making me nervous, one of the main reasons i was ecstatic to get rid of my m7 was signal issues and figured the m9 wouldnt have fixed much but now it seems i may have similar issues with the s6 compared to the m7.
I was dead set on getting an m9 simply for boomsound and the fact ive been with HTC for quite some time now. Never thought i would consider a samsung phone, but then they changed my mind by ditching the plastic and adding fingerprint scanner which ive been wanting since the atrix.

I'm going to say you probably dropped it and it broke the touch screen. I had a similar issue where I dropped my A53 from 3 feet, no visible damage at all to the case, screen protector or phone at all, but the battery would drain over 20% overnight just sitting on my nightstand and Wi-Fi was broken. I tried resetting, nothing worked.
Your next step is to register your phone on the Samsung website, request a repair, and they will send you a prepaid shipping box to send it out to their repair center, and you should get it back in about a week.
The A53 isn't durable at all. It's a nice phone, just don't drop it from more than 18 inches.

Why didn't you send it to Samsung? It's under warranty.
