Watch out for
Common Mobile Devices exam traps
- ▸Assuming a driver update fixes erratic touchpad jumps; palm rejection or sensitivity settings are usually the actual fix.
- ▸Confusing NFC with Bluetooth for contactless payments; NFC must be enabled and a default payment app set.
- ▸Overlooking that Bluetooth auto-connect requires the headset to be paired and set as a trusted or preferred device.
