[Q] Restarting once when i switch on phone.

Hi everyone. Just upgraded from a Galaxy S4 octa to a note 3 4G and I noticed that when I start or restart the phone as soon as it reaches the lock screen it restarts again once and then its OK. This only happens when there is a sim card inserted and it is not in flight mode. We don't have 4g in our country. Could this be the reason?
Anyone noticed the same thing? It is a EUR model N9005 and I live in Cyprus.

Yeah i get that but I'm rooted with a custom rom if you are stock shouldn't really happen
Yeah i'm fully stock. on MJ7
MJ1 rooted/unrooted does it too
Mine has always done it, even before I rooted it. Never understood, but I don't very often restart, so it never bothered me.

935F edge stopped receiving texts on AT&T

A few hours ago my 935F stopped getting texts on AT&T. I can send them fine, but nothing ever receives - they are totally gone.
If I throw my SIM back into my official AT&T phone, SMS works perfectly fine. I tried doing a factory reset, checking APNs etc and nothing will work. The phone is NOT rooted, and was working for several weeks perfectly fine.
Anyone know of something I could try to fix this?
I'm having the exact same issue, also got a 935F and not getting texts on at&t. please help.

me too. not just text but also "no service" at all. ><. Not sure it's because it's not US version but international version has anything to do with it? Region lock?
I have the 935A and have intermittent texting issues on mine but it's sending (maybe I'm not receiving some too??) I am also on AT&T I hope this doesn't happen to me permanently.
Same here. 935F on AT&T. Texts are coming in 6 hours delayed. No idea how many haven't come in at all.

Rooted T-Mobile Galaxy S7 (G930T) Having Signal Issues and Verizon-Related Wierdness

I recently bought a used, unlocked T-Mobile Galaxy S7 and almost immediately rooted it using this guide.
Having used it for a few days however, I've noticed that it's been having issues getting a signal and dropping calls (which doesn't seem to be an issue with T-Mobile which is my carrier and naturally the SIM I'm using, as my spouse has an unrooted T-Mobile Galaxy J7 with none of these issues) and its become quite irritating.
When I rooted the phone it seemingly changed into a Verizon phone or something, as the T-Mobile logo was replaced with a Verizon one, the phone was suddenly filled with Verizon-branded bloatware and I would get notifications from a 'setup wizard' telling me that I'm not using a Verizon SIM card.
I can still call, and receive calls but it's incredibly inconsistent and the Verizon stuff is making me think the root may be the issue as I've tried messing with the network mode (switching from 'Global' to 'LTE/GSM/UTMS', etc.) but it's still really wonky.
I'm not sure what exactly is going on, or if anybody else has had this problem so any help is greatly appreciated.

Help me with my Verizon S8

Hi
I owned an S8 on Verizon for a year or so and switched to Sprint's Bring Your Own Device Plan. One a Sprint SIM was inserted, the phone was rebranded and all Verizon apps were wiped off and replaced with Sprint. Fast forward a few months after, early June, I get a firmware update notification which I prompted to accept (as I have many times before for Verizon and Sprint updates). After the update, the phone worked for a few days and then all of the sudden gets stuck on the word Samsung S8 logo and restarts on its own. It keeps looping!
Resetting didn't work and I sent it to a store nearby (You Break, We Fix) and nothing could get this thing to go back to normal. I think the fact that the phone was on Verizon and was rebranded to Sprint is what caused the problem.
I downloaded Odin but can't figure out which version of the firmware I should use to flash the phone and get it to work. The original box that came with it says SM-G950UZKV and the SW-VER is G950USQU1AQC8. I don't care about the phone's photos/other data, I just want it to work again.
What firmware should I download to get the phone to work?
