In the early 2010s, larger smartphones with screen sizes of at least {{convert|5.5|inch|mm|order=flip|round=5}} diagonal, dubbed "[[phablet]]s", began to achieve popularity, with the 2011 [[Samsung Galaxy Note series]] gaining notably wide adoption.<ref>{{cite web |url=https://www.engadget.com/2011/12/29/1-million-galaxy-notes-shipped-worldwide-us-fans-throw-money-at/|title=1 million Galaxy Notes shipped worldwide, US fans throw money at their screens |first=Mat |last=Smith |publisher=[[Engadget]] |date=December 29, 2011}}</ref><ref>{{cite web|title=Samsung: 10M Galaxy Notes sold in nine months |url=http://news.cnet.com/8301-1035_3-57493718-94/samsung-10m-galaxy-notes-sold-in-nine-months/ |website=[[CNET]] |access-date=January 18, 2013}}</ref> In 2013, Huawei launched the [[Huawei Mate series]], sporting a {{convert|6.1|inch|mm|order=flip|round=5}} HD (1280 x 720) IPS+ LCD display, which was considered to be quite large at the time.<ref>[https://www.androidheadlines.com/2019/05/huawei-mate-flagships-history.html/amp History Of The Huawei Mate Flagships] 2 May 2019.</ref>

Some companies began to release smartphones in 2013 incorporating [[flexible display]]s to create curved form factors, such as the [[Samsung Galaxy Round]] and [[LG G Flex]].<ref>{{cite web |title=Samsung's Galaxy Round is the first phone with a curved display |url=https://www.theverge.com/2013/10/8/4818572/samsung-galaxy-round-curved-oled-smartphone-official |website=The Verge |date=October 8, 2013 |publisher=Vox Media |access-date=March 21, 2017}}</ref><ref name=engadget-gflexfcc>{{cite web |title=LG G Flex appears on the FCC with AT&T-friendly LTE |url=https://www.engadget.com/2013/11/15/lg-g-flex-att-lte/ |work=Engadget |date=November 15, 2013 |access-date=March 9, 2014}}</ref><ref name=engadget-gflexannounce>{{cite web |title=LG G Flex announced with vertically curved 6-inch 720p screen, 'self-repairing' back cover |url=https://www.engadget.com/2013/10/27/lg-g-flex/ |work=Engadget |date=October 28, 2013 |publisher=Verizon Media |access-date=March 9, 2014}}</ref>

By 2014, [[1440p]] displays began to appear on high-end smartphones.<ref>{{cite web |last=Dent |first=Steve |url=https://www.engadget.com/2014/02/18/do-you-really-need-a-4k-smartphone-screen/ |title=Do you really need a 4K smartphone screen? |date=February 18, 2014}}</ref> In 2015, Sony released the [[Xperia Z5 Premium]], featuring a [[4K resolution]] display, although only images and videos could actually be rendered at that resolution (all other software was shown at 1080p).<ref name="engadget-4k1080psony">{{cite web |title=Sony's 4K smartphone shows most content in 1080p |url=https://www.engadget.com/2015/09/15/sony-xperia-z5-premium-not-so-4k/ |website=Engadget |date=September 15, 2015 |access-date=March 21, 2017}}</ref>

New trends for smartphone displays began to emerge in 2017, with both LG and Samsung releasing flagship smartphones ([[LG G6]] and [[Galaxy S8]]), utilizing displays with taller [[Display aspect ratio|aspect ratio]]s than the common [[16:9]] ratio, and a high screen-to-body ratio, also known as a "bezel-less design". These designs allow the display to have a larger diagonal measurement, but with a slimmer width than 16:9 displays with an equivalent screen size.<ref name="ndtv-lgg6">{{cite web |title=LG G6 With 5.7-Inch FullVision Display, Google Assistant Launched at MWC 2017 |url=http://gadgets.ndtv.com/mobiles/news/lg-g6-launched-at-mwc-2017-price-release-date-specifications-and-more-1663697 |website=Gadgets360 |date=February 26, 2017 |publisher=NDTV |access-date=February 26, 2017}}</ref><ref name="verge-g6unveil">{{cite web |title=The LG G6 is sleek, solid, and surprisingly sensible |url=https://www.theverge.com/circuitbreaker/2017/2/26/14741886/lg-g6-announced-specs-features-mwc-2017 |website=The Verge |date=February 26, 2017 |publisher=Vox Media |access-date=February 26, 2017}}</ref><ref>{{Cite news |url=https://www.theverge.com/2017/3/29/15087530/samsung-galaxy-s8-announced-features-release-date-video-specifications |title=This is the Samsung Galaxy S8, coming April 21st |work=The Verge |access-date=October 4, 2018}}</ref>
Another trend popularized in 2017 were displays containing tab-like cut-outs at the top-centre—colloquially known as a "notch"—to contain the front-facing camera, and sometimes other sensors typically located along the top bezel of a device.<ref>{{cite news |url=https://www.livemint.com/Technology/YFHDoI8YuK4SkZqViPN4VN/Why-do-Android-phones-want-a-notch.html |title=Why do Android phones want a notch? |last=Mathur |first=Vishal |date=April 29, 2018 |work=Livemint |access-date=October 4, 2018}}</ref><ref>{{cite news |url=https://www.pcworld.com/article/3293447/android/android-phone-notch-requirements.html |title=Google thankfully bans Android phones with three notches or other exotic configurations |work=PCWorld |access-date=October 4, 2018}}</ref> These designs allow for "edge-to-edge" displays that take up nearly the entire height of the device, with little to no bezel along the top, and sometimes a minimal bottom bezel as well. This design characteristic appeared almost simultaneously on the Sharp Aquos S2 and the [[Essential Phone]],<ref>{{cite news |url=https://www.phonearena.com/news/First-notch-phone-Sharp-not-Essential_id105608 |title=What was the first phone with a notch?

Other variations of the practice later emerged, such as a "[[Hole punch|hole-punch]]" camera (such as those of the [[Honor (brand)|Honor]] View 20, and Samsung's [[Samsung Galaxy A8s|Galaxy A8s]] and [[Galaxy S10]])—eschewing the tabbed "notch" for a circular or rounded-rectangular cut-out within the screen instead,<ref>{{Cite web|url=https://www.pocket-lint.com/phones/news/146822-hole-punch-camera-vs-notch-vs-slider-honor-samsung|title=Is the hole-punch camera here to stay?

Displays supporting [[refresh rate]]s higher than 60&nbsp;Hz (such as 90&nbsp;Hz or 120&nbsp;Hz) also began to appear on smartphones in 2017; initially confined to "gaming" smartphones such as the [[Razer Phone]] (2017) and [[ROG Phone|Asus ROG Phone]] (2018), they later became more common on flagship phones such as the [[Pixel 4]] (2019) and [[Samsung Galaxy S21|Samsung Galaxy S21 series]] (2021). Higher refresh rates allow for smoother motion and lower input latency, but often at the cost of battery life. As such, the device may offer a means to disable high refresh rates, or be configured to automatically reduce the refresh rate when there is low on-screen motion.<ref>{{Cite web|url=https://www.digitaltrends.com/mobile/refresh-rate-smartphone-screen-explainer/|title=What does a 90Hz or 120Hz refresh rate mean for your smartphone screen?|work=[[Digital Trends]]|last=Jansen|first=Mark|date=19 July 2020|access-date=23 July 2020}}</ref><ref>{{Cite web|last=Savov|first=Vlad|date=2018-06-07|title=Android gaming phones have a lot of growing up to do|url=https://www.theverge.com/2018/6/7/17436168/android-gaming-rog-phone-computex-2018|access-date=2021-05-26|website=The Verge|language=en}}</ref>

====Multi-tasking====
An early implementation of multiple simultaneous tasks on a smartphone display are the [[picture-in-picture]] video playback mode ("pop-up play") and "live video list" with playing video thumbnails of the 2012 [[Samsung Galaxy S3]], the former of which was later delivered to the 2011 [[Samsung Galaxy Note]] through a software update.<ref>{{cite news |title=Samsung I9300 Galaxy S III review: S to the third |url=https://www.gsmarena.com/samsung_i9300_galaxy_s_iii-review-761p8.php |website=GSMArena.com |access-date=29 May 2021 |page=8 |date=2012-05-20}}</ref><ref>{{cite web |title=N7000UBLS4 – Galaxy Note Android 4.1.2 Jelly Bean TEST firmware From Tel Cel Mexico |url=https://www.sammobile.com/2012/12/13/n7000bls4tce-%E2%80%93-galaxy-note-android-4-1-2-jelly-bean-test-firmware/ |website=SamMobile |date=2013-02-17}}</ref> Later that year, a [[Split screen (computing)|split-screen]] mode was implemented on the [[Galaxy Note 2]], later retrofitted on the Galaxy S3 through the "premium suite upgrade".<ref>{{cite web |last1=Reisinger |first1=Don |title=Samsung's Galaxy S3 to get Premium Suite upgrade |url=https://www.cnet.com/news/samsungs-galaxy-s3-to-get-premium-suite-upgrade/ |website=CNET |language=en |date=2012-12-07}}</ref>

The earliest implementation of [[Window (computing)|desktop and laptop-like windowing]] was on the 2013 [[Samsung Galaxy Note 3]].<ref>{{cite web |last1= |title=Samsung Galaxy Note 3 User Guide |url=https://www.tomsguide.com/us/samsung-galaxy-note-3-guide,review-2906-3.html |website=Tom's Guide |language=en |date=2013-09-07}}</ref>
