I am affected as well, loads of users also reported the issue update downloads and then on install at 26% aborts and reboots you then get an error message, update is corrupt you phone is perfect, report via members app and send @samsunguk a message on twitter the more people shouting the quicker the fix
What you need to do is download Samsung smart switch on your computer, connect your phone to the computer and then start Samsung smart switch. You can download the update from smart switch and it will install on your connected phone. 🤞 That helps.
since the other days latest update the battery runs out fast. I would normally get back home with 50 % remaining and thats using it all day video with a Bluetooth speaker at work now 0% straight after update draining the battery 🔋
