Performance Issues
Experiencing lag or delays with your Bluetooth tablet? This guide covers common performance issues and solutions.
Quick Fixes (Try These First)
These simple steps often resolve performance issues:
- Toggle Bluetooth: Turn off and turn on Bluetooth on both your mobile device and PC
- Restart both devices: A fresh restart can clear temporary issues affecting performance
- Re-pair the device: Remove the pairing on both devices and set it up again
Mobile Device Fixes (Android/iOS)
Move Closer to Your PC
Bluetooth signal weakens with distance. Stay within a few meters of your PC for the best performance.
Reduce Bluetooth Interference
Bluetooth can be affected by interference from nearby devices and electronics:
- Turn off unused Bluetooth devices nearby
- Move away from other active Bluetooth devices
- Move away from WiFi routers
- Move away from USB 3.0 devices and cables (they can emit interference)
Disconnect Other Bluetooth Devices
Running too many Bluetooth devices simultaneously can degrade performance. For optimal results:
- Disconnect Bluetooth headsets, mice, and keyboards from your mobile device if possible
- Test again to see if performance improves
Disable Battery Optimization
Android may throttle Bluetooth performance in battery saver mode. Check your device’s battery settings and disable optimization for VirtualTablet to ensure consistent performance.
Adjust Input ‘Report Rate’
This setting controls how many position updates are sent from your mobile device to your PC every second.
- Higher Rates: Provide smoother, more fluid cursor movements and better precision for drawing or writing.
- Lower Rates: Reduce the amount of data being sent, which can help if your Bluetooth connection is unstable or your device is struggling to keep up.
Recommendation: While a higher rate improves the experience, exceeding your device’s processing capacity or Bluetooth bandwidth can actually cause lag. If you experience “stuttering,” try lowering the Input Rate until the movement becomes stable.
PC-Side Fixes
Check PC Performance
High CPU usage on your PC can affect input responsiveness. Close unnecessary applications and check Task Manager to ensure your system isn’t overloaded.
Disconnect Other Bluetooth Devices
Having too many Bluetooth devices connected to your PC can reduce available bandwidth. Disconnect Bluetooth headsets, mice, keyboards, and other devices temporarily to test if performance improves.
Desktop Onboard Bluetooth Chipset
Desktop motherboards sometimes use less powerful onboard chipsets, which can struggle to keep up with the data flow required for low-latency inputs. This is especially true for older chipsets that only support Bluetooth version 4.x.
To ensure the best possible, lag-free experience, we highly recommend one of the following:
- Use an External Bluetooth Dongle: This is the most reliable solution. A dedicated dongle (such as those made by
TP-Link or CSR) often includes its own dedicated antenna and consistently delivers high performance.
- Pro Tip: Even a BT 4.x dongle will often perform better than an onboard BT 4.x chipset.
- Use Bluetooth 5.0 or Higher: If you are buying a new dongle, look for one that supports Bluetooth 5.0 or newer to guarantee full, optimized performance.
