Razer Viper Mini DPI Deviation Problem

Hi,I have bought my razer viper mini 3 days ago,and I don't know,and I tested the DPI deviation on this site, https://www.mouse-sensitivity.com/dpianalyzer/ (DPI Analyzer - Mouse Sensitivity Community) I have installed the Synapse and I have the newest Firmware. Please Razer or the community,respond to this,I have 11 days more to send it back,but I don't want that,It is very good for me,not really used to it,but I can because I have it less than one week. So if you know how to solve this,pls respond to this,or Razer,pls update your Firmware ,because I saw other mice that are having this problem,and the companies fixed their dpi deviation problem,not fully but a lot better. Thank You for all the comments!
