Absolute garbage......havent had a single issue intil i did the android update last night and now its garbage no messages sent Properly.....internet issues..... app updates etc. Crap......Sprint WTF!??!
I was thinking the same things... I think it has to do with the Marshmallow update. Since I upgrade last week I have been having a lot of network issues.
My Galaxy S6 has been having nothing but problems sunce the last update!! No one can hear me when i make calls and text are not going out. Did all updates and Sprint did a reset. Todays code.... 425. Very fustrating!! I have a tower (Airave) in my home. Zip code is 78028. Ive been hearing for years that the towers are being worked on.
