After the latest update on my Galaxy S20 Ultra, fast charging stopped working with my 100W charger, though it still works fine on my boyfriend's Galaxy S22. Removing the update fixed the issue. Has anyone else experienced this? Do you think Samsung is intentionally crippling older phones to push users toward newer models?
You can remove a firmware update. I removed the latest phone update, and it fixed the issue. You can do it with a clear cache partition by booting recovery mode š
@YenniWin That does not remove the firmware update. The wipes out old temporary cache values which may be corrupted or invalid with the new updated software.
It's a good practice to do this after every firmware update.
Okay, I talked to a Samsung technician, and that's what they said. So I'm just repeating what I was told. Regardless, clearing temporary cached data resolved the issue of not being able to fast charge.
