touchscreen scrolling and wifihostspot

[orangzeb]

Sometimes when I scroll it clicks automatically. Could this be issue of protector? or should I install a custom ROM?
Also when I enable wifi hotspot without mobile data on it says "Error occured while"

Stock D6603 Unrooted.

Re flash the latest stock ROM and check if you having the issues. Hotspot issue will be fixed for sure.
About the touchscreen clicks, your LCD might be having dead pixels.
Download touchscreen test app and check if all the touches are visible.
