I'm a few months with the S8 now and can't stand it. The lag is just horrible, and I really don't want to have to reset my phone. If I could just reset like iPhone with restoring from iCloud it wouldn't be quite the ordeal.
I'm getting constant frame drops. Even the text messaging app is slow to draw texts.
The most annoying thing for me, though, is the camera. From the time I press the shutter button it takes about 5 seconds to save a photo. If I press the home button or turn off screen before those 5 seconds are up, it doesn't save the photo. I've been losing a lot of photos lately and just realized today that's what the issue is. I often take a pic and put phone back in my pocket, only to later find it never saved it. If I watch for the little icon in the bottom corner to show the pic was taken, I see it takes about 5 seconds for it to show up. If I turn off the screen before that point is when the photo is lost.
Also, when I'm recording video it isn't smooth motion on the screen, it stutters. However, the actual video playback is fine after I view it on my PC.
Another very annoying feature is how to answer a call when Do Not Disturb is turned on. It doesn't pop up on the screen like normal but rather a tiny icon like a notification on the screen, and you've got to turn on screen by pressing home button or power button prior to being able to answer. I've missed many calls at night trying to fumble in my sleep to answer calls from people on my favorites that I can hear ring.
And back to the camera... it can't capture color accurately. It thinks orange is yellow. I've taken some pictures of sunsets that were a beautiful deep orange and they come out as lemon yellow. I took some pictures a few days ago of candles and they come out yellow instead of orange. The dark green grass in my yard looks like a bright green -- completely different than what it looks like in pictures I took with my prior iPhone, which was always color accurate.
One other issue that's been troublesome lately is the GPS or location feature of my phone isn't doing right. I use IFTTT triggers for turning lights off and on when I leave and return home, and sometimes those trigger and turn the lights off while I'm sitting at home. I know it's an issue with the phone's location because I also use Smart Lock and it coincides when the lights turn off when I'm sitting at home that I have to use a password to unlock phone. It's like it thinks I'm somewhere else.
I'm ready to go back to iPhone already.
