If recent history is any indication, Apple (NASDAQ:AAPL) will unveil its next iPhone in September. The iPhone 6S is expected to resemble its predecessor, but sport improved internals, a better camera, and additional features, most notably Force Touch.

In recent weeks, Google's (NASDAQ:GOOG) (NASDAQ:GOOGL) Android partners have unveiled several new handsets, and more could be on the way. The following slideshow offers a rundown of the various smartphones that should compete with the iPhone 6S, including devices from Samsung (NASDAQOTH:SSNLF), HTC (NASDAQOTH:HTCXF), LG (NASDAQOTH:LGEAF) and BlackBerry (NYSE:BB).
