I bought a S4 mini on eBay, I got it today and realized some marks on the soft key area (see photo)
So I messaged the seller and he claim that this phone is from the very first shipment which the made in Korea and those phones are like this and there's nothing I should worry about,
Now, I have the same identical phone which also says Made in Korea and I'd doesn't have those marks,
Does anyone here know what those marks are and knows that this doesn't indicate that something is wrong with the phone?
