220-1101 Mobile Devices Practice Question
A user's Android phone was dropped and now the screen displays a network of fine cracks that spread across the display, but the touchscreen still responds and the image is visible. The user wants the phone usable again as quickly as possible while preserving the existing data and avoiding a full device replacement. Which of the following should the technician perform?
⚠ Common exam trap
The trap here is assuming that a still-responsive touchscreen means only the glass is broken and a cheap glass-only repair is possible, when the digitizer and LCD are bonded into one module.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Replace the digitizer and LCD assembly with a compatible screen module.
Because the glass, digitizer, and LCD are laminated together on most modern Android handsets, the correct repair is to replace the complete screen module. This restores full usability and preserves the user's data since storage and mainboard components are not disturbed. Cosmetic coatings, software resets, and accessibility toggles cannot repair fractured glass or the display stack beneath it.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Replace the digitizer and LCD assembly with a compatible screen module.
Why this is correct
On most modern Android phones the outer glass, digitizer, and LCD are bonded into a single module, so a cracked display that still responds is repaired by replacing that entire assembly. The phone's storage and data remain intact because the mainboard is untouched, and the phone becomes fully usable again. This is the standard, fastest repair path that preserves user data without replacing the whole device.
- ✗
Enable a screen-protector mode in the accessibility settings to mask the cracks.
Why it's wrong here
Accessibility settings adjust how the interface behaves for vision or motor needs; there is no setting that hides or repairs physical cracks. Some phones offer a touch-sensitivity mode for screen protectors, but that does not address broken glass or the risk of further damage. The display would still be cracked and the user's problem unsolved.
- ✗
Apply a liquid screen protector to fill the cracks and seal the glass.
Why it's wrong here
Liquid screen products are cosmetic coatings applied to intact glass; they do not restore structural integrity or prevent crack propagation. The underlying damage remains, and pressure on the cracked glass can still injure the user or damage the display layers beneath. This does not return the phone to a reliable usable state and is not a repair for impact damage.
- ✗
Perform a factory reset to recalibrate the touchscreen after the impact.
Why it's wrong here
A factory reset erases user data and has no effect on physical glass damage; touchscreen calibration is a software function that cannot repair cracked layers. This action would destroy the data the user wants to preserve while leaving the crack untouched. It also risks losing the ability to back up if the device misbehaves after the wipe.
