Bench Signal #007 — three things from the bench, every Tuesday.
① This week's tip
Intermittent Face ID after a drop on any recent iPhone. Before touching the TrueDepth module, check the earpiece bracket screw.
A hard drop can loosen it just enough to shift the module a fraction of a millimetre out of position — no visible damage, no cracked components, just geometry that's off. Tighten the screw, re-test Face ID enrolment. Fixes a surprising number of cases that looked like module failures.
Thirty seconds before you start pulling the TrueDepth assembly.
② Prompt of the week
Use this to build a response template for online reviews:
I run an Apple repair lab. Write professional response templates for Google and Facebook reviews. I need: (1) a response to a 5-star review that thanks the customer and mentions we're available if they need us again, (2) a response to a 3-star review where the customer was satisfied but had to wait longer than expected, (3) a response to a 1-star review where the customer claims we damaged their device. All under 80 words each. Tone: professional, human, not defensive.
Responding consistently to every review, positive or negative, is one of the few things you can do that directly affects whether new customers choose you. Most shops don't bother.
③ Resource this week
Complete specs database for every Mac ever made. Model identifier, RAM slots and type, storage interface, GPU, display specs, upgrade limits, and which OS versions are supported. Free, no login, no ads. Useful when a customer brings in something old and you need to know exactly what you're working with before quoting a repair or upgrade.
That's it for this week.
If this was useful, forward it to a colleague who'd appreciate it.
