Back Tap on your Galaxy phone has been a let’s-see-if-it-works feature until now, but Samsung has released an update for the feature that will make it click with far greater regularity. The company’s RegiStar module in the Good Lock suite has been updated to enhance detection, mitigate false negatives, and fix a glitch that broke Back Tap under power saving mode. There’s also a small but crucial bug fix that’ll allow Gemini to launch properly on the Z Flip cover screen.
What Changed in RegiStar to Improve Back Tap Reliability
Per Samsung’s changelog in the Galaxy Store, today’s RegiStar build is all about stability, not new functionalities. The Back Tap engine has been optimized to more accurately recognize taps, and a “function error” that occurred when power saving was turned on has been fixed. In real-world terms, that translates to fewer missed double- or triple-tap actions and occurrences of Back Tap quietly ceasing to work after you turn off battery-saving features for it.
The update was first pointed out by the Samsung watchers at SamMobile, and it comports with what I’ve heard from several users on Samsung Community forums: Back Tap worked well initially, then became inconsistent (particularly if you used cases or battery-saving optimizations). This release is aimed at those exact weak spots.
Why Back Tap Doesn’t Register Every Tap You Make
Back Tap uses your phone’s motion sensors and on-device pattern recognition to interpret rapid, rhythmic taps on the rear panel. Three things frequently get in the way: large inelastic cases that deaden vibrations; background limits that slow down sensor polling; and settings that turn the sensitivity up too high. When power saving mode is activated, Android can lower the sample rate of sensors and shift background tasks to a low-priority task list, which means that gestures sometimes don’t register right when you’re looking to save on battery.
It’s not unique to Samsung. Google’s Quick Tap on the Pixel series experienced its own similar reliability “ups and downs” for a while, until Google changed the sensor thresholds. The takeaway: Small tweaks to sampling windows and motion thresholds can have a major, daily impact on success rates, and that’s exactly what Samsung seems to have tuned here.
How To Get The Update & Improve Accuracy
Updating is, again, simple: open up Galaxy Store and search for Good Lock and RegiStar; update both to their latest versions. Once you have installed the apps, restart your phone to make sure that the gesture service is cleanly loaded.
Then recalibrate your setup in Good Lock > RegiStar > Back Tap. Try these expert tweaks:
- Use medium sensitivity to start and test with your case on, nudging it up only if need be. Higher is not always better — too high can lead to unintended actions when you set down the phone.
- Select the gesture that matches your grip. The double tap opens quicker but can be prone to false positives with a bit of movement; the triple tap is slightly more determined and often works better with thicker cases.
- Allow RegiStar and Good Lock to bypass battery restrictions: Settings > Battery > Background usage limits, then add them to Never sleeping apps. Check App power management as well, and if available set it to Unrestricted.
- If you use power saving mode a lot, try using Back Tap after activating it. With this active, behavior should be the same throughout, but it’s a little safety valve to make sure you trigger what you intend.
- Stay away from cases with chunky air gaps or a rigid kickstand near the center of your phone; those can absorb the micro-vibrations that Back Tap relies on to detect your taps.
Fix Lands for Gemini on Z Flip Cover Screen
Samsung also mentions a fix for a “Gemini app launch issue” on the cover screens of Flip phones. The company doesn’t make the root cause explicit, but it seems to have something to do with how an external display brings up app activity. If you lean on Gemini from the cover screen to quickly run prompts, they’ll launch more reliably after updating.
What This Means for Good Lock Power Users
This is a quality-of-life upgrade, but it’s a significant one. For Samsung, Good Lock has emerged as its play space for advanced features, and RegiStar is the module that a lot of users are going to find themselves touching every day. A reliable Back Tap, even one you must stabilize occasionally, refines a gesture that, when it’s functioning as designed, feels invisible — in the very best way. Combine it with an action like flashlight toggle or camera launch and you’ve got muscle memory that can translate to real time saved.
Recent updates to Good Lock have broadened the scope of automation and customization, including Routines Plus, Home Up, and One Hand Operation Plus. With the latest reliability boost today, it once again proves that the Samsung ecosystem has always favored individuals who love to customize their devices beyond stock settings.
