There is a gap between the back cover and body of my device.

A gap has formed between the back cover and body of my device and it is getting wider day by day. Initially I thought it was due to falling, later when I realized it is getting wider I thought of writing here. One of my friend said your battery has swelled and that's pushing the cover outward. 

As far as I know battery is placed downwards, my device is opening from top. Battery backup is okay, thus, according to me it's not the battery.

Also, some sticky material is often seen coming out at the opening.

Help! Do I need to check out at service center, if yes, is this covered under Care+ extended warranty?

How old is your s20fe? If it's more than one year old, check your phone's backpanel carefully. S20fe is one of the most affected models.

Immediately go samsung service center. And check that device.

S20 and A52 series have this issue. You don't have to necessarily post a photo. We all know that the issue is genuine. Go to a service centre and paste the panel back. It's the only option. Hundreds of users are facing this issue due to poor manufacturing quality. I faced it myself.
