The Calculator app is pre-installed on all four Wonder Phone variants — the L'Maaseh-approved Wonder Phone (Talk+Text and Talk+Features) and both VAAD Hakehilos-approved Wonder Star models (Talk+Text and Talk Only). No variant is missing it.
Opening the Calculator
Find the Calculator icon on your home screen and tap it, or navigate to it with the D-pad and press the center button.
Entering Calculations
Use the on-screen number pad to enter numbers and operators. Press the equals button to display the result. You can also use the physical keypad to type digits directly.
Known Fixes in Recent Updates
Two calculator-related bugs were addressed in recent software updates:
- Large equations — An earlier bug caused the result to have no room to display when an equation was long. This was fixed in WonderOS v1.5.8.
- Changing the operator symbol — A separate bug required pressing the back button to switch an operator (for example, from + to ×) mid-equation. This was also fixed in v1.5.8.
If you are experiencing either of these issues, open the System Updater app and install any available update. The current release is v1.5.8, which includes all prior fixes.
Keeping the App Up to Date
The Calculator app does not require any separate updates — it is updated as part of the regular WonderOS system updates. To check for updates, open System Updater from the home screen.
Variant Notes
The Calculator is available on every variant, including the stricter Wonder Star models. There are no calculator features that differ between variants.
