Cell phone contacts lost when phone automatically updated

So my phone, a Samsung S7, just automatically updated and erased 90% of my contacts, which apparently weren't backed up on my Gmail account. Any fancy techy people know if there's a way to jumpstart my phone's memory into remembering all of these lost numbers?
