Why my SideSync on Tab S keep scanning when I connect to PC?

SideSync on my Tab S can not find PC.

Ad

Make sure the Tab S and the PC are on the same network when scanning. For instance, the PC could be connected to one WiFi network while the Tab S is connected to Guest settings on your router. If you are connected to the same network, disable the firewall on your PC including the Windows firewall or Windows Defender if you have a separate 3rd party firewall. If these solutions do not resolve your issue then uninstall SideSync. Put the Tab S in Recovery Mode but Wipe Cache Partition and then Dalvik Cache. Install SideSync again. When using SideSync, disable any 3rd party security apps you may be using on the Tab S as well.

Update your Display drivers in the PC. If this does not work then upgrade your Windows version to Windows 10 since that will be the latest available update. After doing this, you still may need to update your display drivers from the PC manufacturer's website so wait until you update Windows. Uninstall and then reinstall the SideSync then try again. You will need the latest OS for the Samsung for the SideSync to work best.

SideSync should now work properly but if not then follow solutions above such as disabling your firewall and making sure that you are on the same network over WiFi for both devices.

SideSync connection problems with Samsung S4 and Lenovo Laptop?

SideSync 3.0 is on both the Samsung S4 and the laptop. But neither USB or WiFi will connect them. Via WiFi the devices won't "find" each other. Via USB it starts to work, the phone screen goes black and we got as far as getting typing to work, but the screen itself won't share. We've installed a lot of different drivers trying to get it to work but no luck

Disable your Firewall on the PC. This is the likely reason that neither WiFi or USB won't work. Then check to make sure your USB debugging is on within your phone settings which could be a secondary problem. If you have installed drivers and updated every other thing then one of these is stopping or interfering with the connection.

Connection problem, using USB cable?

I woke up to find my phone with a black screen, so I wanted to see in my computer all the last messages or phone calls before I take it to costumer support. I installed SideSync to help me with this task, but although it's connected to the computer with cable, it doesn't connect. (I can't access my Bluetooth either, because of the black screen). Can you help?

If your phone was locked then your USB is locked and this is why SideSync is not connecting. Depending on your Samsung device, you may be able to unlock it remotely using Samsung's Find My Mobile. Then you can try to connect using the USB. Also, if you have hardware damage which is causing the black screen this means that no matter what you do, it will not be able to connect to the PC.

How to connect to my laptop?

Connected Galaxy Tab 4 to laptop through USB. SideSync 3.0 running on both, just get scanning on tablet it never connects, same thing happens when I try to do with WiFi then get scanning on both

For the tablet, did you install SideSync from Google Play or Samsung apps. They are slightly different versions so uninstall and reinstall from the opposite and see if the tablet now connects. Also, your tablet may not yet be compatible or an older Samsung tablet which also would stop it. If your tablet OS is JellyBean this would be another issue because it works for Kitkat 4.4.2 and above. Try updating your tablet to a newer OS such as Lollipop or Marshmallow if compatible or available. You can get the version of OS within Settings and then About Tablet/Device.

You are probably not connecting both devices to the same network or your firewall on the PC is blocking the connection. Also, update your drivers in your laptop and see if this helps with the connection.

Have SideSync installed on S5 and HP Laptop. Works on WiFi but not on USB connection?

S5 and laptop USB fail. WiFi OK.

See if other things work through the USB. You may have a corrupted USB port. Also, make sure in the S5 that your USB debugging is set properly. Especially if you lock your screen on your phone. Disable the screen lock and then try. If all else fails, troubleshoot by disabling or enabling one thing at a time and then try to connect. Make sure that your USB cable is 3.0 or higher as well.

Just self-solved. iMac/S4 connection dropping. Perhaps for your FA?

Running Lollipop with developer options "Do not keep activities" enabled. Connection dropped within half a second. Disabled "Do not keep activities".....Sweet.

Awesome that you resolved the error on your own! Thanks for sharing your solution for pairing the iMac and S4!

My tablet and laptop don't recognize each other with SideSync while connected with USB. How can I solve this problem?

My tablet is a Samsung Galaxy Note 10.1 and my laptop is ASUS

Can you connect via WiFi? Follow the procedures mentioned above and also update your drivers directly from the ASUS website for your specific device. If you are not on Windows 10 then consider upgrading your ASUS to that Windows platform.

Have a Mac with 10.9.5 OS. Connects well through USB but not through WiFi?

Upgrade to SideSync 4.0. Samsung improved connections to Mac OS with this latest version. Disable Do Not Keep Activities on your Mac as well which is a solution another Mac user shared. Make sure that you installed the Mac version of SideSync from the PC download section on Samsung.

You would not use Samsung SideSync for this. Instead, the correct program would be Samsung Smart Switch. Connect over WiFi to the same network and share. You also could back up everything with Google and then when you sync your S7, it will appear on there. The S7 also comes with an OTG adapter to use to transfer items.
