I just recently switched from an iphone to a Samsung Galaxy S7 edge for the first time. I have always been an iphone user and used imessage and icloud. After I switched, I made sure to turn off imessage, remove my phone from the icloud etc. However I still am still not able to participate in group chats with iphone users. I know this was a huge problem in 2014/15 but I thought apple had fixed their glitch. I made sure that people deleted my contact information and re-added it (which is a very dumb solution by Apple), yet it still doesn't work. I almost regret making the switch and may just switch back to an iphone because it is such a pain. I would think Android would have taken care of this because they really are being affected by Apple's monopoly with the iMessage. A few friends that have made the switch before said to wait it out because after awhile it'll just fix itself, which makes no sense, or they just switched back to the iphone. Thanks for the help!
