Issues with losing connection to network since September update??

Has anyone else had issues with the "radio" since the last update to G935TUVU4APIA??  I know John Legere had announced late August we would be getting an update for the radio to activate the 4X4 MIMO and 256QAM in the S7 and S7 Edge so wondering if there is a glitch in the firmware.  Since the update it has happened few times when I notice the phone has been quiet or I try to do something and it says it is in "offline" mode.  It shows bars but no E, 4Glte, 4G etc and when I go to service mode it shows what Band it is seeing but says "idle".  I have to go into airplane mode once or twice for over a minute or two and that seems to kick the radio back on and it is fine again.


Curious if anyone else has seen anything "hinky" with the radio since the update.

T-mobile should definitely be more responsive about this.  With that said it looks like the Nougat update is imminent. The support site shows the update has been released to TMO and they are currently testing the update on the S7 series.

Don't forget, a full reboot shouldn't be necessary.  You can use airplane mode on/off 2x and should be able to get a signal again.  Since I discovered that trick I've not had to reboot which has been a time saver.

Thanks for the input. I remember when it first started happening to me, way

back, a T-Mobile rep had me try the Airplane mode trick and it worked for

me...twice lol. I try it now and I haven't gotten it to work since. I've

tried to put it in AP mode, wait a full minute or two only to still have to

reboot. It doesn't work for some but it's because they are probably not

waiting long enough before turning APRIL mode off. Unfortunately, I'm

stuck with the reboots. It makes me wonder if the software issue might be

frying a component. If it worked before a couple times and then it stops

working to the point that only reboots will work, something changes. Maybe

something with files, I don't know. Like I keep saying, this is my

replacement S7 and it's been having the same issue right out the box.

They're looking into it lololol. Yep. ***I want the next person who

experiences this issue and has seen this thread but hasn't yet contacted

T-Mobile, when you finally do connect them, ask if they have heard of this

issue before. I wanna know how often they lie or try to cover up issues.

Then please post. I have 4 phones on my account and have been pouring $$$

into them for a long time now. I'd love to leave em.

I saw somewhere maybe back a few post to try safe mode to disable non factory-installed apps  I'm going to give it a shot and head to Costco where I know it will kill the signal. I'll report my results later or tomorrow.

Been busy never got to try the safe mode trick yet. Now I see they released the nougat update. Anyone try it yet to see if it helped fix the issue?

I just did the update this morning.  Looks like it's one of those you have to be really patient with.

It's been a couple of days since I've had the issue and hopefully that was the last.  If the problem continues I'll be sure to post an update.

BTW,  I didn't get the baseband/firmware versions before update.  I'd be curious if that's been updated at all.

Nougat Baseband: G935TUVU4BQB1

Kernel: 3.18.31-10376601

Build: NRD90M.G935TUVU4BQB1

Android 7.0.

1.3GB update inbound. Hopefully fixes this issue

So far so good.  As mentioned I did the update the day it was released.  I've been in and out of my office and the gym which are the two places most likely to force a reset.   No reboot/airplane mode toggles needed yet.

Anyone taken the update and still having issues?

Still good here as well. I was expecting to be disappointed but so far so


‌After the 7.0 update I am no longer have issues with connectivity. Yay! Looks like for now there's no more problems for me to complain about. Hope everybody else has the same experience. Best wishes!!!

So far so good, everything is going well.

I don't see the added 10% battery drain that I heard about.... In fact mine

seems slightly better.

My update is in and I have been to all the "dead spots" and all seems well. I use to walk into Costco and have emergency calls only. Now I have 4g on my display. When I walk outside I still have service. I was in Atlantic City in a few casinos where I had no service but as soon as I go outside the service returns. Even the trip down through the New Jersey pines where it was loaded with dead spots was much improved. I do think i am seeing a little more battery usage. I my need to tweek a little yet. My double down casino app crashes every time I open my chive app too.

I've noticed since that update if I go to a deadzone with my s7e and go back into a covered area my phone will never connect back to 4g. I normally have to activate airplane mode twice to reconnect.

I haven't gotten any update on the J7 issue continues but T-Mobile saved me they offered a brand nee Iphone SE or LG G5 free of charge no strings and told me to keep the J7 until an updat for the device is rolled out. Took the G5 no issues at all.

Thanks, I didn't try step 1, but 2 and 3 somehow got my phone to finally reconnect to the network!

Hi. I am having this exact problem and just found this thread. Any updates on a fix?

Having the same exact issue and it's infuriating! I had it happen 4 times this past Sunday while out and about, it's very sporadic and I can't seem to duplicate it. I did a factory reset in hopes it would help but it is still occurring (actually did the reset Friday evening and Sunday was terrible). I even had a situation where it showed I had 4G LTE but nothing would connect.
