Upon its release, ''4 Walls'' was praised by music critics for increasingly showcasing all members' vocal abilities with "trendy" production.

It also earned success for f(x) in the United States, becoming their second release to achieve No. 1 on the ''Billboard'' World Albums Chart and charted at number thirty-nine on the Japanese Oricon Albums Chart.
To promote the album, its titular track was released on October 27, 2015, to both critical and commercial success, peaking at number two on both the Gaon Digital Chart and the ''Billboard'' World Digital Songs. The group also appeared and performed the single on several music programs, including ''M Countdown'', ''Music Bank'' and ''Show! Music Core''. The group further embarked on their first concert tour, titled Dimension 4 – Docking Station, which visited South Korea and Japan in January and February 2016, to promote the majority of the album and their past releases.

''4 Walls'' was subject to favorable reviews from music critics. Jeff Benjamin from ''Billboard'' shared that despite the fact that the album was "arguably worse" than f(x)'s previous albums ''Pink Tape'' (2013) and ''Red Light'' (2014), it allowed the other members to showcase their vocal abilities more following the departure of Sulli. He praised it as a "rarity in K-pop to do once" by "finding the right sonicscapes" and appreciated the "house and trendy dance" production.<ref name="BB_Review"/> Benjamin subsequently named ''4 Walls'' the second best K-pop album of 2015, writing: "Known for crafting some of the best full-length K-pop albums, f(x) did not disappoint with their long-awaited 4 Walls comeback."<ref>{{cite magazine|url=https://www.billboard.com/music/music-news/best-k-pop-albums-2015-6828137/|title=The 10 Best K-Pop Albums of 2015|first=Jeff|last=Benjamin|magazine=Billboard|date=December 30, 2015|first2=Jessica|last2=Oak|access-date=May 9, 2016}}</ref>
Sheldon Pearce on behalf of ''Pitchfork'' labeled the record a "superficial rebirth" following f(x)'s lineup change and commented that the other members had the chance to express their talents more, particularly with Amber's alto "harmonies" on "Rude Love".<ref name="pitchfork"/> Jakob Dorof, upon reviewing the album for ''Spin'', disliked the songs "Deja Vu", "Papi", "Cash Me Out" and "When I'm Alone". He nonetheless labeled them "minor misgivings" and complimented ''4 Walls'' on featuring "sophisticated and innovative" musical styles that could "signal a surprise second life for the world's greatest living pop group."<ref name="spin"/> Echoing Dorof's viewpoint, Chester Chin of ''The Star'' was not impressed by the inclusion of the "derivative" tracks "Glitter" and "Cash Me Out", yet expressed his admiration for the "solid and edgy" album's "more cohesive" sound as well as "more polished and sharper" beats.<ref name="star"/>
