Hey everyone! I ran into the same issue with the One UI 7 update getting stuck during download. After some trial and error, I found a simple trick that actually worked:
1. Pause the download
2. Restart your phone
3. Resume the download
It started downloading again smoothly. I was stuck at 57%, and with just two restarts, I had the full update installed in about 10–12 minutes.
If it gets stuck again, just repeat the process. Hope this helps someone out!
