Samsung S6 After Update 5.1.1 Data signal and testing very slow!

[cee_dub2003]

So i updated a few days ago to 5.1.1 Sprint service! A couple differences/ problems are:
#1 Seems to me my data signal isnt good. It shows the LTE signal but when im surfing the next or even on ebay seems to just have the searching circle. then maybe a min or so later it will go. Ill surf again and data will just stop. It seems the data isn't communicating with the phone intermittently

#2 My text sending is way way slow now. Before update it would send pretty much within second of me hitting send. Now it displays the sending for a good 30 seconds! Sometimes even longer.

I have restarted multiple times/ update PRL/ Updated profile multiple times.

Welcome to Android Central! Also try a cache partition wipe: https://support.t-mobile.com/docs/DOC-21095. If nothing helps, then bring the phone to Sprint and/or the Samsung Store at your local Best Buy, and ask them to reflash the firmware.
