My aunt had this same problem and I didn't believe how crazy it was until I attempted to use her phone, I never seen a phone act like that. I tried an assortment of things to fix it but nothing I tried worked. She did have a screen protector on that I thought could be causing that problem but I guess not. She has sense then taken it back to version and had it replaced. No issues from the referb.
