Sorry. The Windows Central app gave me an error on this thread so I assumed that my thread didn't get started so I started another threadYou've got two threads on this... Here's what I typed into the other one:
faith3935... I don't know what "sunspots" are in terms of screen display.
Let me ask. Do the spots show in a screen shot? (I'm guessing not.) If yes, share a screen shot here...
It sounds more like your phone may have been water damaged and it affected the display or someone cheaped out and only replaced the glass and your digitizer is not adhered properly.
Take a pic of it with a camera and upload that.
Start a conversation with the seller about a return and if they are being a jerk get (eBay? Amazon?) the site involved.
I Binged 'sun spot on screen' as I've never really heard of this term.
Do you have a photo?
There are many threads here on bright spots on the screen in the area around the main camera. That light leakage can be seen only in light backgrounds. I've had two 1520s and both developed spots. They are annoying but these days I'll have to forcefully notice to see them, I got used to it and doesn't bother much..
But if by sunspots you actually mean a dark spot.. then I guess I have not seen that anywhere...
