2. More accurate

It has an extra display on testbox which you can see the screns voltage and currency itself, from this function you will be able to find whether screen get some problem
Market many people sell TFT lcd as OLED screens, as their currency different so you will be able to find whether they are selling fake oled while it is a TFT screen.
S300 can test touch panel only which means if innder lcd broken you can switch to “tp test only” model and test whether its touch panel is able to recycle. And still as touch panel testing only model you can identify 8 Plus and below from Incell structure to other qualities.
When testing if flex cable not plug well the display will have error info so we know what cause it.
When updating system some people failed, before they dont know why it happened, now there is error info, like USB failed, file issue or something.
And there are more functions you can find from our S300
