The LG G4 is a decent smartphone, and that’s about all that can be said about it. With that in mind, it’s no surprise that the device was met with lukewarm responses from critics and customers alike, but LG must have learned from its mistake, because we’ve been hearing some crazy rumors about the device’s successor. According to a report from last month, the LG G5 will actually feature a semi-modular design and a unique button arrangement, and will be one of two flagship smartphones that LG releases this year. We won’t know if the former rumor is true until the LG G5 is actually announced, but we won’t have to wait that long to find out, because LG tweeted on Wednesday that it’ll be unveiling the smartphone at the Mobile World Congress on February 21st.
