How to customize the side button on your Samsung Galaxy phone

Samsung Galaxy users can remap the multifunction side button through Settings > Advanced features > Side button, assigning double-press actions such as Camera, Flashlight, Voice Recorder, Modes and Routines, or a chosen app. Long-press functionality is limited to assistant apps including Bixby, Google Gemini, ChatGPT and Claude, or the power-off menu; older Galaxy models with dedicated Bixby buttons have more limited remapping options.

Analysis

This is immaterial to Alphabet’s near-term earnings, but it modestly reinforces Gemini’s distribution advantage in Android ecosystems where Samsung permits assistant selection. The economic value is not the shortcut itself; it is whether repeated hardware-level invocation increases default assistant retention, query frequency, and eventual migration from low-monetization assistant interactions into Search, Workspace, and paid AI services. Any benefit will be measured over 6-18 months, not in the next quarter.

The competitive implication is more meaningful for Samsung’s bargaining position versus Google. Samsung can expose Gemini, ChatGPT, Claude, or Bixby through the same user behavior, limiting Google’s ability to treat Android distribution as exclusive. If Samsung broadens AI-assistant choice across Galaxy devices, Google’s incremental AI engagement may rise while its share of that engagement remains contested; this favors ecosystem-wide model providers but constrains direct monetization and supports a higher traffic-acquisition-cost risk over time.

Consensus should not extrapolate customization availability into a material Gemini adoption catalyst. The long-press interaction is a low-friction distribution surface, but users must actively change settings and the use case competes with the power menu, making conversion uncertain. The relevant verification points are Galaxy default settings, regional Gemini attachment rates, assistant query retention, and any Samsung-Google revenue-sharing disclosures; absent those, there is no standalone trade signal.

Key Decisions for Investors

• No directional trade in GOOG from this development; the expected earnings impact is below materiality and requires evidence of sustained Galaxy-level Gemini engagement over the next 2-4 quarters.
• Maintain a 6-18 month watch on GOOG’s Android AI distribution: upgrade the thesis only if Gemini becomes the default assistant on major Samsung flagships and Alphabet shows accelerating Gemini usage without a corresponding rise in TAC or AI serving-cost pressure.
• For AI-platform relative-value exposure, monitor GOOG versus MSFT rather than buying GOOG on handset integration headlines. A widening of Microsoft’s enterprise AI monetization lead, or Samsung materially promoting third-party assistants, would weaken the distribution-premium case for GOOG.
• Thesis falsifier for any future long-GOOG AI-distribution position: declining Search query share, accelerating TAC as a percentage of ad revenue, or disclosure that Gemini assistant usage is rising without incremental Search/paid-product conversion.
