Best trigger to wake up device for semi-disabled senior: Proximity vs Significant device motion (most sensitive with least effort)?

[Alex]

Device/context

• Initial device state: Sleeping with the screen turned OFF

• Goal: fire a flow which wakes up the sleeping device and turns ON the screen from the weakest possible gesture (no hardware buttons).

• Considering Samsung A-series (A15, A16, A20) that may use virtual proximity

What I’m trying to choose between

1. Proximity block (wave near the top bezel). Docs note: “May not work on devices with a ‘virtual’ proximity sensor.” — does anyone have reliability tips on devices with virtual proximity?

2. Significant device motion block (small nudge to the phone). Docs say it operates while asleep and wakes the device on motion — in practice, how light can the movement be before it triggers?

3. Device acceleration block (set a low threshold). For very weak movement, what ranges/filters have you found stable (to avoid false triggers)?

Ask

• For a semi-disabled senior, which trigger is more sensitive to minimal effort in real-world use: Proximity (wave) or Significant motion/Acceleration (tiny nudge)?

• Any recommended thresholds/sensitivity and battery-optimization caveats so the trigger remains responsive with the screen off?

• If proximity is virtual, should I abandon it and rely on Significant device motion instead?

Thanks for any guidance or example flows!

Interesting and you need to deactivate the trigger once screen is turned on or it may cause repeating trigger I don't think proximity work well for that mean.

The The sensitivity of Significant motion block is difficult to tell since it's determined by the system.

The Acceleration block is probably the most sensitive, but also use most battery. 

You need to test to see which works best.
