I have a Samsung Galaxy 7, and for the past month I have been experiencing an issue with a delay in sending text messages and receiving them. I am using the messaging app which came with the phone, and do not use other messaging apps. When I attempt to send a message, I will see a spinning circle where the time stamp should be. After I realized this was happening, I also discovered I was not receiving text messages when others had been sending them. I have a screenshot to share which demonstrates my issue. The circle will spin for a long time, and sometimes it will say it failed to send and I will have to attempt to resend, or it will eventually send. Initially, I attempted to solve the problem by closing all apps, and rebooting the phone. When this did not solve the issue, I called T-Mobile for assistance. They had me check the phone setting be sure it was set to the preference to use the cellular network instead of Wi-Fi, and then had me clear the cache & data for the app, as well as sent a refresh signal to my phone. It worked initially, but two days later I was experiencing the same problem. T-Mobile suggested I reboot the phone in Safe Mode to check if there was any interference with other apps which may be causing the issue. This attempt did not solve the problem, and T-Mobile suggested I factory reset my device (and I am still struggling to regain all of my personalized phone settings). After all of this, I am still experiencing the same problem. I have just checked the coverage in my area, and where I am the T-Mobile website shows "4G LTE - Excellent Signal." I do not appear to be experiencing delays with any other functions on the phone. I have no idea where to go from here. I would greatly appreciate any help.

Wow, over 14 years!! That's incredible. I definitely don't want to jeopardize that and I completely understand the need for your outgoing texts to send right away. There are times when I can't physically talk on the phone and rely on text messaging. I'm truly sorry this option isn't as reliable as it used to be. I ran across another thread of users that had S8's and they're having the same exact issue. As I mentioned to them, I'm going to reach out to our Samsung guru to see if they are not only aware of the issue but have any fixes. I know this means waiting a few more days for answers and if I could avoid the wait I would certainly do that. I may not hear back from them until Monday or Tuesday but as soon as I do I'll be sure to follow-up with you. In the meantime, I'm going to send you a private message to get a few details about your device to pass along. You can check your inbox here.
