It might be a good idea NOT to do the most recent software updates for the Galaxy S7 phones. We KNOW it's affecting unlocked phones, such as my Straight Talk phone and other carriers as well. Uncertain of carrier-locked phones. Simply put, the update (the Straight Talk S7's rolled that update out 8/16, I have two, both are now experiencing the issue) has "braoken" the SMS Function. If we send an SMS message, we receive the "Message failed to send" error, even though the text often goes through to the recipient. The concern is, while we can still have a text conversation, we end up with a ton of "failed" messages. Strangely, however MMS works great, so we're forced to send every message as an MMS message with a "ghost" message to some unassigned landline (in my case, my home number) as a "group" conversation.
Samsung refuses to take responsibility. They're saying contact the carrier. The carrier says "contact samsung". It's not carrier specific. It's happening on multiple carriers. Samsung will not acknowledge the problem nor are they offering any type of solution.
Until we can find some way to make them take accountability for their update and fix it....users might want to delay or avoid that software update that's rolling out.
Is this something you can help us get the word out on?
