Okay so today I went to the exclusive nothing service centre in Delhi experience was awesome
First they changed the middle glyph section (that big c type which comes with wireless coil) but issue was still there so they replaced the motherboard. it worked fine but when I reached home they glyph issue is still there
I have contacted the service centre they asked me to visit them on Monday hopefully it gets resolved.
Now I am having issues with insta gram.i cannot login into my account from app and web both I guess it happened because of motherboard change
