My Samsung A70's cellular has been dropping in and out of service every 3-5 seconds. I was following this guide on unlocking more data bands for my device and the phone disconnected while I was in the process. My phone is now dropping in and out of service every 3-5 seconds, taking the wifi with it. I have factory reset and reflashed my phone multiple times and have tried to go back into QPST & QXDM to revert the changes. In QPST & QXDM it can't find the phone again because of the constant loss of service. Is there any way to reset the Qualcomm memory addresses or any known fix?

I have 8525 with official ATT WM6 and noticed the following problem - after getting to the area with no reception (deep in the garage) when I return to the area with perfect reception my data connection never restores until I manually turn flight mode on and then off. If I forget to do that - my email is not pushed until the next reboot. I quickly realized that I can restore it by soft reset, but then I figured that cycling of the flight mode helps as well.
Can something be done about it?
I discussed that with ATT tech support and they basically say it is “by design”:
“Nigel_G: To konste
I have checked into this further for you what happens is when you go into a area with no service and come back the voice should reconnect automatically but the data service needs to refreshed to connect like power cycle, soft reset or turning flight mode on and off this forces the device and the network to reconnect the data services.”
Sounds weird to me. Anybody can comment?
Thank you!

Same problem with my phone
It seems that we have the same problem.
I have noticed that the phone would report "Searching..." if it is currently searching for a signal. "No Service" means that the phone is in a no service area.
In my experience, after going into back into an area with known good signal, sometimes my phone displays "Searching..." but will never get a signal. I have to manually turn on and off flight mode. When "No Service" is displayed, the phone never ever tries to find a signal.
I have tried upgrading radio rom but it never helped.
I hope someone can shed a light into this matter.
Hi, my phone keeps losing connection from cellular network.. I've had my phone for about a week and I keep disconnecting from cellular network, or sometimes when I'm picking up a call from home the reception is really bad this has never happened to me from my previous phone, Apple iPhone 3G
does anyone have a solution to this?
I had this issue as well. I know you won't like what I did, but it's the only way that Samsung knew how to fix the issue (I had tried things like disabling the LTE antenna to no avail). I did a complete factory reset, and it helped. What Sprint has you do is go into Settings, then Backup and Reset, then Factory data reset. What I did, however, was using Odin to flash the PALEN firmware to my phone, then do a factory reset as Sprint said above (using Odin will not erase data), and lastly doing OTA updates until I got back to LI3. I will post a video from QBKing below on how to do this. From there, I reinstalled all of my apps and re-synced my music.
I did this about two weeks ago. Since then, my phone has only disconnected from the network once, which it did so to switch from 3G to Wi-Fi.

This video shows you how to unroot your device if it is already rooted. However, you can use this video to know how to flash back to PALEN (just ignore the part about unrooting at the beginning).
Good luck!!
Disclaimer: I am not responsible for any loss of data.
So, I have had the G3 since day 1, D85110c (haven't taken the update due to TWRP), rooted. For the past I have been having an issue where my phone will be connected to 4g fine (in a very strong 4g area) and my phone will randomly lose data connection completely. It will show I still have bars (4 to 5) but I am unable to receive or send calls and text and obviously don't have data.
The only way to fix this is to either airplane mode on then off, which does not work most of the time, or completely reboot the phone. It started with only happening once every few days, but in the past 2 weeks it has been every 30 minutes I find my phone has no connection.
I tried using the mod to change to IPv4 but that did not work.
Any help would be much appreciated.
So I got this phone from my Grandpa who recently passed. I was able to insert my AT&T SIM, reboot, and use the phone as normal on 4G+ without any issues what so ever.
Fast foward 24 hours and after rebooting my phone a couple of times and accidentally "Updating Profile" my 3G/4G no longer wants to connect. What's strange is Voice and Text still work as long as the text isn't a MMS since that server is also no longer connecting.
I have confirmed the radio is functioning as I can switch it off, verify it's receiving signal from the nearest WCDMA tower through the 4636 menu.
As well as airplane mode and wifi are working
Sometimes my wifi will not connect first-time unless I "forget this network" and use WPS button on Router to connect - it's like my phone won't authenticate the network once a password is entered. Once connected it stays connected without issue.
Some things I have tried already:
I have attempted to change APN settings to strictly AT&Ts 3G connection - no luck.
I've installed custom ROM, Recovery (Bad Boyz HTC 10 Oreo Stock ROM, TWRP) - no luck.
I've reinstalled stock firmware from HTC RUU - no luck.
Got a new SIM from AT&T and had a tech "diagnose" my phone - no luck.
I've searched all over the internet and found multiple threads about having no signal or no IMEI, but this doesn't completely fit my issue as you can see in my pictures I still have a valid IMEI and cell signal. AT&T said everything is fine on their end regarding my phone, but since it is not an AT&T phone any other support I'm going to have to find elsewhere (Screw AT&T)
The only other thing I can think to try is purchasing a Sunshine license to S-OFF and try manually deleting the radio partitions and then reflashing an older radio or stock radio, but I'd rather not spend $25 for this solution to not work or further complicate my matters.
My question is has anyone experienced this random loss of 4G connection but still have the ability to call and text on their HTC 10? I know this is an older phone, but I really like this phone after using my LG V20 for so long.
UPDATE: Put the SIM in my LG V20 that I was using prior to switching to this device and it is also now having the same issues.... Wtf is going on?
Thanks for any responses!

At your own risk, this:
In the bootloader enter these commands:
fastboot erase modemst1
fastboot erase modemst2
(this will wipe the faulty modem partitions we are about to reset)

I'm hoping someone has seen this and knows the solution.
I have a Pixel 3XL, bought Nov.`18. Unit has a case, never dropped outside, it's in immaculate condition.
A few weeks ago, I noticed the LTE Connection would restart every 8 to 12 seconds (going from LTE - LTE+, back to LTE)
I did a ton of things (restarted device, safe mode, Factory Reset with stock setup (no backup) and even did a Factory Image restore of Android 10 from September)
Nothing has resolved this issue. The case has been removed, a different SIM Card was purchased.
Even when changing the connection to 3G, it changes from HSPA - to 3G every 10-15 seconds. I've disabled VoLTE and even used the phone after factory image restore, with a new google account (to make sure no settings were copied over from previous install). Checked APN settings, all good there. I've had every PIXEL phone on my carrier (Rogers, in Toronto) without any issues like this.
At this point, I am thinking hardware.,
Does anyone have any insight into why this would just start randomly in November?

Mine and now my pixel 4 have a similar issue. But it seems to randomly drop to 3G and get stuck until I put it in airplane mode and take it out...

Take a SIM Card from a different Carrier, see what happens. That will show if its Hardware, if it keeps happening.
Mine had the LTE connection reset every 10 seconds no matter what SIM Card I used from different carriers.
I got a replacement Pixel3XL today, and the new unit is working perfectly - so it was hardware 100% on my end.
