Note 7's Iris Scanner & Light Sensor Stopped Working...

I finally received my preorder Note 7 on Thursday 18th Aug, was very excited to try the Iris scanner but unfortunately it stopped working after setup/transferring everything from Note 4 to Note 7 and also realized that the phone doesn't have auto brightness check box in quick setting or in settings->Display. So did a factory reset hoping to get Iris and brightness sensor to work but
no luck.
So I called T-Mobile about the issue, she told me to call Samsung. Called Samsung explained everything to the Samsung Rep, he said he is gonna put me on hold and phone got disconnected plus he didn't call me back even though he asked for me number in case of disconnect.
when i called the second time the samsung rep told me to take the phone to Best Buy for Samsung Experience Consultant to REFLASH the Firmware. I asked her if she can send me the firmware so i could flash it myself, she said No it has to be a Secure Flash.
Today i took the phone to Best Buy and samsung consultant check the phone and saw that Iris is keep failing when he tried to Setup it up so he connect it to his Laptop to flash but unfortunately the phone would register with his laptop so he couldn't do anything and told me to have T-Mobile replace the phone since it is defective.
Called T-Mobile after going through all that BS. TMO Rep told me since the phone is on JOD I'd have to return the phone by Mail and wait till they receive the phone then i can go to a T-Mobile store and buy a new Note 7.
I love the phone but all this BS makes me not to get another Note 7 after i return this defective one on Monday.
UPDATE:
Returned the defective Note 7 and bought another one from the store. this one is working fine and No issues yet. Thank God.
And it will probably take weeks till i get refund for the defective one that i returned...

I am sorry if you got a defective unit. Just be aware that T-mobile does treats this as RMA, which in this case, they will process it as a return, then they would send a new one. If I am you, I would return it, then get one from the store. If you had any issues escalate the issue because it's certainly not your fault and they should be faster!

man that sucks. I normally dont have to go through all that if i need a replacement. They send me out another phone and i put mines in that box and return it.
But i would try a full reset from the boot menu.
Once you done that add your patten then reboot.
Then try the iris scanner.
Also have you try to use odin yourself to see if the phone get detected?

I couldn't find the Firmware that time to odin it myself. I tried to Smart switch's device initialization and it asked me for model and serial but no firmware available to download.
I did factory reset from Recovery and from setting but didn't help.
it was definitely hardware failure not software.

SM-G800F not registered on network, what can i do?

Hello, my S5 mini has the first problems 1 year after bought, sometimes there was the error not registered on network. I have sent it twice to the support, but it was returned with "no error".
Now warranty over i have the error not registered on network, and can not use it for telefoning. The IMEI was correct, i can receive the network, but i can not register to it. I have the last marshmallow update flashed over OTA.
in former times, i have to remove the sim and reinsert it, to get it work again, but now this does not work. The simcard ist changed from the provider, and i bouhgt another simcard from another networkk, to test it.
Can i fix this problem?

Sam here, call me cynical but happened 6 months after phone ran out of warranty. Done all the basics, diff SIM from different provider reset phone, even re-flashed phone and no joy, tried all the modem software going and phone will only work on 2G. Samsung support said take it to repairers hmmm wonder what that's going to cost. New phone, New manufacturer I think. This is 2nd Samsung ive had issues with

I've only just got my first Android phone from a mate after obnoxiously using iPhones for years+, an S5 Mini that lags and ****s itself at every moment. I've now got a gangsaf little unit learning anything I can about this phone and after all my errors, not once have I seen this.
Just for relevancy, I have a G800Y model but I'm using one of the two kernels I could find that looked decent which the devs have listed under G800F and as far as I can tell or what I've read, there's no real difference other than a difference between the LTE bands they can access (someone please correct me if I'm wrong). If it would be so much as to ask what exactly is the software specifications of both of your devices? By this I mean:
- What ROM are you running; [Stock] or [Custom]?
- Have you rooted your device?
- Have you tried finding your device's most recent stock modem software?
- Did anything lead to this or is there anything you believe could have contributed to the occurence of such a problem?
- What carrier are you with in what location? If you do not wish to say for whatever reason, have you tried a search for devices with similar problems and a possible resolution method?

Hello, i have stock rom, IMEI is intact, not rooted,
Basisbandversion G800FXXU1CQB2
Kernel Version 3.4.39-895f4887
Buildnummer MMB29K.G800FXXU1CPL1
AP: G800FXXU1CPL1
CP: G800FXXU!CQB2
CSC: G800FDBT1CPL1
SIM-Card from Telekom or blau.de, both does not work.
I can receive the Providers, but can not connect.

Galaxy S6 T-mobile relocked automatically

I had gotten a T-Mobile Galaxy S6 off ebay (refurbished), and I'm not a US resident. The phone and network worked perfectly fome until today, two days after the nougat update, the phone automatically restarted and said that my device is network locked and it can be unlocked using the Device Unlock app. Now when i opened the device unlock app it stated that my device is not elegible for unlock. What should i do now? There is no chance of me going to US or any way tgrough which i can send this phone back to US. Is there ANY possible way in which this can be unlocked? Additionally, the IMEI has changed I guess, the IMEI on the back is different from the one in the *#06# menu. Is there any way to restore the network on this phone or am i stuck with a $250 brick?

Same thing happened to me. I know the person who I bought it from, she has called tmobile and requested another unlock to be sent to the phone, aftet 48 hours they just sent an email saying the device can only be unlocked through the app. Have you found any resolution? I'm thinking we'll have to downgrade the software somehow.

First check your IMEI if its changed you'll have to get it fixed by Z3X box, I got my phone fixed through Z3X box, you can't fix it yourself, and after the repair I had to stay on Marshmallow as the latest update at that time (a month ago) didn't support Nougat. Only unlocking the phone won't fix your issue, it'll keep showing (Searching) in the network name.

Likelihood of Warranty Exchange

Hi all,
Have a question for you. Bought a used S8 off of a guy on the internet awhile back. Phone worked fine for a few weeks, but now has developed a problem where it claims no service and as such there is no data/calling/texting. Factory resets sometimes do or don't fix this issue. If it is fixed with a reset, it reoccurs within some hours. I have sent this in five times to Samsung. It has been out of my possession for weeks and weeks with the constant shipping back and forth. It is currently being shipped back to me. I assume in a not-fixed state. The service center people can't replicate the issue because it magically doesn't occur when they run their suite of tests on the device. As a result, they literally do nothing to the phone and also won't replace it. What is the chance I could go into a T-Mobile store and have it replaced? Thanks for your time.

Normally in order for T-Mobile to exchange the unit, they would need to access the original buyer's account and see the warranty status. I first thought your phone's IMEI could have been blocked by T-Mobile, but you mention that after factory reset it works sometimes. Use T-Mobile's IMEI checker website and see what it shows you. https://www.t-mobile.com/verifyIMEI.aspx If you phone is unlocked, try another sim card, from another provider such as AT&T.

I was just assuming it wasn't blocked since it works on and off, but yeah, that site is telling me it is blocked on their network. Thanks. Guess this was a complete waste of money.

I believe there is a chance that T-Mobile might unblock it depending on why it was blocked in the first place.

Samsung S10 G973F mobile data issue.

I recently bought a second-hand S10 off eBay with the intention of refurbishing it. The screen was badly damaged and I was able to fix it. The phone runs as it should but it turns out it has an issue. Whatever sim I put inside, It doesn't recognize it, Defaulting to Emergency calls only. At first, I tried checking the IMEI number to see if the phone was blacklisted; From what I could find nothing really helped. One website said that Telstra had blacklisted it in 2021 and most of the others said that it was clean with an expired warranty. (IMEI: 354616100350193) I am currently installing Aussie (TEL) firmware onto it to see if that helps due to the fact that it had Baltic (SEB) firmware on it. I'm not sure if the phone is locked to Telstra though, as I put in a Telstra sim and it also couldn't recognize that. Here is where it gets weird. I ended up trying to root the phone but forgot to flash an RMS disabler and the phone got bricked. I used Odin to reflash the Baltic firmware onto it and alas, it booted again, This time it had a data connection though. I used it for a while but then had to call someone, they picked up and we both said hello; Then the phone hung up and the issue started again. Somehow calling someone made the phone bug again but messaging that same person and using data didn't?
TL;DR: So the phone is capable of reading the sim but chooses not to, and somehow bricking it fixed it until I called someone.
