S21 Intermittent SMS Fail - Samsung Galaxy S21 Questions

Hello folks.
I'm having an issue with my phone, S21 Unlocked SM-G991U1 (purchased directly from Samsung). This post might be long because I want to include all info to help answer questions that I might already have eliminated possible issues on.
I bought the phone March 18th and it's been working perfect up until exactly 4 days ago. What's been happening is that it will fail to send sms/texts randomly throughout the day. I can be having a conversation with someone then suddenly the texts I'm sending will begin to fail and they will get the ! or endless spinning circle depending which messaging app I'm using. I tried several apps (stock messaging, Google messages, textra) to eliminate the possibility of it being a specific one, it happens with all of them.
I then switched my sim card to another phone for several hours (S8) to see if it was a network issue... The S8 works perfect, no failed texts. As soon as I switch the sim back to the s21 the messages will fail again.
This happens at any given time, it will go from working fine for about 5 messages in a row then fail on every next message for about 10-15 mins then start working again.
This does not affect MMS or phone calls. Only SMS.
I'll also be able to receive any sms messages sent to me without issues at any time, even when outgoing ones fail.
I've tried resetting Network Settings to no avail.
I just did a complete factory reset, also no to avail. I'm lost here.
The phone has the latest update and had been working perfect up until 4 days ago. I can also say that I don't think the latest update was the cause because it started the day before I received the push notification for the update.
I'm on AT&T prepaid.
Please let me know if you have any questions I might not have covered or if you've encountered this issue before or what might be the fix. Thanks in advance!

delayed text messages

right,
my wifes starting to lose her temper with her hero.
she send over 150 text messages a day, but receiving them seems to be a very hit and miss affair.
she gets texts ok for a while, then gets nothing for 10-20 mins (from what i can tell) then all the ones she has missed arrive all at once.
orange UK have basically told her to naff off and talk to HTC.
so, can anyone tell me whats causing the problems, is it an orange problem, or a phone problem.
if its the phone, whats causing the problem
doing a bit of a search, one explanation seems to be that the phone is running out of memory and it shuts down the text app and relaunches it later on, if so, how can i prevent/stop this happening.
she is on the current rom from HTC which she installed about 10 days ago to try and prevent this.
thanks in advance for any advice / help you can give
from what i have read on the forum it might be a problem with the stock messaging app.
try installing handcent sms or chomp sms from the market and see how that goes.
don't forget to turn off the notifications from the stock sms app or you will get multiple notifications for the same message.
also if your wife is using task killer applications she should put the messaging app on the ignore list!
Me too!
I am having this very same problem, although on a slightly smaller scale (150 texts/day?!). I also get the problem where callers are going straight to my voicemail when the phone is right beside me, receiving full signal, which, to my mind, would seem to be related.
I spoke to Orange who fobbed me off with "oh, there's a mast down in your area, switch to use 2G only", despite my protestations that the problem occurred when I was in different parts of the country...
Interestingly, it happened with my Touch Diamond as well when I first got that, about 18 months ago; I was never sure that it was completely cured, but it sure as hell wasn't as bad as it is now on my 2 month old Hero with stock Orange ROM.
My twopenneth, for what it's worth.
P.
Try a new updated Radio rom maybe? One way to tell if its a network issue is to make calls to 150 for about 10 seconds and see if the stuck messages come through, if so its a network issue. I wouldn't let orange customer service fob you off they don't have the reporting tools to actually look into the issue's.

[Q] Phone can send texts and make calls but not receive either.

I usually find solutions to my own problems while lurking, but this one is stumping me.
Starting last night at some point I stopped being able to receive both calls and texts. I was quite confused because I was in the middle of a text conversation with someone and they just stopped responding.
Data still works and I can make calls and send texts, but when I send myself a text from another phone nothing happens and calls just go to voicemail.
The phone was on the Eugene 2E JK2 Froyo ROM. I re-flashed it, then flashed it back to stock and nothing helps. When data is off it still doesn't work.
Any ideas? I tried searching but couldn't find anything. My GoogleFu may be lacking
Weird, have you contacted t-mobile support? Many years ago on ATT, with an old school flip phone, I had a similar problem. One night, my phone just suddenly stopped being able to receive or make calls. It could only text. The only solution was to get a replacement--it was not software related.
I've got a new phone on the way because I've been experiencing a similar thing, off and on for the last few days. I called T-mo and went through all the troubleshooting but they can't find any reason for the phone to be behaving this way...gonna send me a new one as warranty replacement.

[Q] Stock Messaging causing reboots?

As part of my job responsibilities I am on call and receive pages for system alerts. Sometimes, we get many (hundreds) of alerts at once. The first time this happened with my S4 it rebooted itself after about 30 SMS messages were received in quick succession. Three more times this past weekend it did the same thing. At the time I was on the lock screen, so the SMS notification thing was up on the screen, and I could tell it was having trouble updating the screen with the frequency of incoming notifications.
Anyone else experience this problem, and do you think Verizon would accept this as "faulty" and exchange my phone for something that can handle SMS notifications, if there's no fix?
No I'm not rooting, if I pay for a working phone I want a working phone out of the box. If I mess with it afterwards, THEN I have only myself to blame, but I'd like to get this issue worked out before I do that, as I have done with all the phones I've rooted/unlocked.

Android 5.1.1 notifications don't notify when screen off

Hello,
Recently purchased an LG V10 with 5.1.1 stock, AT&T, and I've done absolutely no modding.
Scenario 1: sending hangouts data messages over LTE (for example; they are quick and easy to test with) work OK from my end. On receiving phone on different carrier, message arrives in about 5sec. Slower than I'm used to on every other phone I've used but not a big deal. SMS are sent faster and arrive in the normal amount of time which is still faster than hangouts.
Scenario 2: My phone is asleep\screen off and hangout messages are sent from the other phone to mine over LTE. My phone does nothing for as long as I let it stay asleep. But Incoming phone calls to my cell number notifies me instantly and
SMS sent to my phone notifies me instantly.
Scenario 1 and 2 are the same when using Wi-Fi, and with other apps that can trigger notifications when the screen is off. Those notifications only appear after I've unlocked the phone, and some appear only after I've opened the app. The notifications will have correct timestamps but the sounds and visuals only happen once I've picked up the phone and started using it; they all flood in at once.
I've made sure that my settings for allowing notifications (priority it's called on the LG ROM) is set to allow everything.
I've done a lot of searching online and people with various phones (Galaxy S6's most recently) appear to have this issue and it also appears to have a history as far back as Android 4.1. They say the fix is an app that changes the checking times from the stock Android 28minutes or something, down to like 5 minutes. I have tried one that doesn't require root and it has not changed any behaviour that I can measure.
My question is, is this a phone problem? Like a bad OS install from the factory (did i just get a bad unit?) or an APN setting issue (haven't messed with it from factory settings) or is it an Android problem that needs a bug submitted since I see it happening on Samsung phones too?
I've had many other phones, mostly Samsung and even a Note 4 with Android 5.1.1 but hangouts and emails and every other notification was practically instantaneous whether on Wi-Fi or cell network.
Thoughts?

Duplicate / Delayed Texts

Hey all,
I purchased this phone off Amazon about 6 weeks ago and instantly feel in love with it. And this was right before they announced that Sony would be selling these phones in local retailers in the US.
I've noticed for the last few weeks now, however, that some texts are coming in multiple times. It can range from 3-7 times that I receive the same text, and you can imagine how annoying that'd be. Sometimes, when I send a text to someone, I'll receive a duplicate of the previous text I got from whoever last texted me. Sometimes, I won't receive a text until much later- up to hours later. To top it off, sometimes MMS or group texts won't come through without prompting me to download the text. It wasn't bad at first, as it would happen sparingly, but now it's constant.
I've tried many options, from
- switching and updating/downgrading texting apps (Hangouts, Messenger, Stock texting app)
- editing and switching APN settings
- clearing my phone's cache.
To give some context, I transferred over my data from my Moto X 2013 and moved everything to my SD card the next day after transferring everything. The phone is not rooted. I'm also on AT&T but haven't contacted them about the issues yet (I would rather avoid hours of basic troubleshooting, unless they can actually fix it).
I'd really like to not have to lose all my text messages, and I shouldn't have to. Has anyone else had a similar problem and managed to fix it? What other routes should I try? If factory reset is the only option, what's the best way to back up and restore all my data (contacts, photos, texts)?

are you using the stock texting app? I had these issues when I tried to use a 3rd party messenger a very long time ago. other than that Ive not had this issue.
also maybe check out your system time, something might be up with your towers in the area. I use clocksync as cricket had issues a few months back and I fell in love with the app.

Thanks for the reply,
I use Hangouts as my default texting app. The week that I used the Stock Texting app, I still received duplicates and delayed texts, so I switched back to an interface that I enjoyed more. (Also, the Stock texting app is sometimes really slow when opening conversations)
My system time is on point, but I went ahead and turned off automatic sync for the time and dates.
What settings do you use for Clocksync, and did it fix any texting issues? I just now installed it.
Update to Marshmallow. See if that fixes the problem

Come to think of it google talk is what I was using when I was having those issues haha. probably not related but its something to keep in mind.
i use 1 hour intervals only when awake. idk if you need to be rooted or not for it to work.
There may be a problem with your sim card. Had this a while ago on another phone. Got the sim card replaced and it was gone
A few days later and I have some updates:
1. Have yet to change out my sim card. I will be going to ATT tomorrow to see if that fixes the issue.
2. Marshmallow update is not yet available. However, if I read it right, won't it disable using an external sd card? I wouldn't want to be rid of that feature, it was a big selling point for me.
3. I switched to the stock text message app, and it seemed to work well. It stopped duplicated texts from happening, but some MMS texts don't come through to me at all, and if they do they appear much later. Some texts I receive don't come in until about at least an hour after the contact sent it. Sometimes even 7 hours. Not to mention, the app itself is terribly slow.
4. I tried to switch back to Hangouts for a day after downgrading the app and using the stock texting app, but still had the existing issues from before.
5. Clocksync hasn't done anything for me.
Double Post,
Update:
It appears that getting a new SIM card did the trick after all. Went to the store on Saturday, days ago, and the texts don't appear to be duplicating and they seem to be showing up on time. I'm even back on Hangouts again. Yay!
You just need the patience to deal with how busy the store may be.
If anything changes, I'll let y'all know.
