The Galaxy S7 is an older Android phone, so this is mainly an old-stock and used-market category. Its Android version, Bluetooth pairing mode and the specific game’s controller support matter more than the controller’s brand. Bluetooth HID controllers are the least physically demanding option; a wired USB controller needs the S7’s micro-USB OTG adapter and may not leave room for charging. None of these makes every Android game support a controller: use games with native Android gamepad support, or confirm that a controller’s own mapping app still supports the S7’s Android version before purchasing.

An older Bluetooth Android controller with a full-size grip and MOGA Arm phone holder, appropriate only when its companion-mode and app requirements work on the installed S7 software.

- Used-market option for native-controller Android games

- separate phone mount needed
- Comfortable full-size form
- No clamp size to force around the S7
- Discontinued and does not include a phone mount
GameSir G3s

- phone clip
- multiple device modes
- Phone clip makes a self-contained handheld setup
- Common used-market Android controller

- Modern controls and readily available used/new stock
- Clip avoids needing a separate mount
- Check Android-version support and game recognition before purchase

- Bluetooth wireless
- Android mode
- compact SNES-style layout
- Portable and well suited to D-pad-focused games
- Separate clip lets the buyer choose a case-friendly mount
- No included S7 clamp and native game support still varies
Razer Raiju Mobile
A Bluetooth Android controller with an adjustable phone mount, made for Android 6.0 and later; its mount range needs checking against the S7 plus any protective case.
- Bluetooth Android connection

- remappable controls through supported software
- Purpose-built mobile-controller form factor
- Android 6.0 minimum includes a normally updated Galaxy S7
- Discontinued and companion-app availability can affect remapping
iPega PG-9023
A telescopic Bluetooth Android controller whose expandable clamp holds the phone between two control halves; confirm the S7-with-case width against the seller’s listed clamp range.
- Bluetooth Android mode
- telescopic phone clamp
- built-in controls on both sides
- Handheld-console form avoids a top-heavy clip
- Often inexpensive on the old-stock market
- Generic-controller firmware and mapping quality are variable
Buying tips
- Update the Galaxy S7 as far as your carrier model permits, then test Bluetooth pairing before installing a mapping utility. A controller that pairs successfully may still not be recognized by a particular game.
- Remove a thick case before judging a clamp fit, and do not force the phone into a telescopic controller. The S7 itself is about 70.6 mm wide; the case and clamp padding change the real fit.
- For wired controllers, use a known-good micro-USB OTG adapter. OTG confirms a physical USB connection, not automatic controller support or a way to charge at the same time.
