一日一計---What a shit is SideSync

Today, I keep trying to interact my Samsung Galaxy J2 with SideSync provided by Samsung. Yesterday, I use the USB cable to do this, but failed. Today's new approach is a little tricky. I setup my old Sony Xperia J as an AP, and connect both of my laptop and J2 to it. The result was sweet, I successfully sync with J2 and use mouse and keyboard on J2. But, there still exist some bugs that I can't get the mirror image of J2. Above all, I still wanna to Sync with my J2 on cable, in the consequence of speed and stability. After all, the stability isn't as perfect as I consider a product of international company should be and I am very disappointed with this application.😒😒😒😒
