On the inner display
Apps built with older SDKs are placed in a phone-sized safe area on a black background. Everything works; you just don't get the bigger screen.
In Split View
iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including League of Legends Mobile (China). Open it on the inner display, then add a second app next to it. You can save the pair and come back to it later.
Duo-specific features
None confirmed yet. Duo-specific features include side toolbars, layouts that react to the fold, and content on the outer display while the app is open inside.

Version 7.3.3.2818 · Sep 21, 2026
笔锋落定，虚空遁行！7.3版本迎来三位全新英雄——异画师 彗、解脱者 塞拉斯与虚空遁地兽 雷克塞，同步开启S23排位赛季与“卷笔刀”峡谷宝典。本次更新围绕普攻与暴击体系、射手生态、装备系统展开大规模重构，并为野区经济与防御塔带来全新的玩法机制，让峡谷对抗节奏更清晰、策略深度更高。 【新英雄】 彗：来自艾欧尼亚的天才画家彗，能将汹涌的情感倾注笔端，凝成撼动现实的法术。他是一名远程法师，主打中路。他以画为刃，可组合出十种法术，兼具远程消耗、范围控制与护盾治疗，是上限极高的全能型法师。 塞拉斯：“解脱者”塞拉斯生来就能感知魔法，因此被德玛西亚的搜魔人囚禁多年。逃出之后，他成为反抗禁魔的旗帜。他是一名近战法师战士，大招“其人之道”可窃取敌方英雄的终极技能，面对不同阵容随机应变，团战中愈战愈勇。 雷克塞：“虚空遁地兽”雷克塞潜伏于恕瑞玛沙海之下，靠震动感知一切猎物。她是一名打野战士，擅长遁地和挖洞，凭借遁地穿行与声呐标记神出鬼没，她总是长途游走与突袭gank，是让各条分路都不得安宁的顶级猎手。 【新赛季】 我们即将迎来S23排位赛季，赛季限定皮肤“声威助力 米利欧”上线。S23赛季开启时间为2026年9月23日，详情请关注排位赛入口界面提示。 【娱乐模式】 娱乐玩法更新：乐斗赛季S7将于2026年9月23日开启！符文大乱斗“音浪”赛季，新增“心之钢”“真实伤害”“五连摇滚”等乐队主题符文卡套系和多件专属装备，带来更多流派组合与战斗体验。 【新宝典】 新一期“卷笔刀”峡谷宝典将于2026年9月22日正式开启，带来全新皮肤 卷笔刀 克格莫及其升级版 卷笔刀 粉红侏罗纪 克格莫。本期宝典在福利与体验上全面加码： “圣诞驯鹿”小小宝典：“卷笔刀”峡谷宝典结束后，全新的“圣诞驯鹿”小小宝典将于2026年12月3日上架，带来全新皮肤 圣诞驯鹿 斯莫德 及炫彩皮肤 圣诞驯鹿 草莓糖果 斯莫德。星纹券在两者间通用，小小宝典结束后未使用的星纹券将被系统自动回收。 【全新系列皮肤】 7.3版本将陆续推出多款全新皮肤。“赤壁风华”系列将为斯维因、迦娜、崔斯特、费德提克、盖伦和蔚带来全新造型。此外，更多全新及返场系列皮肤也将在版本期间陆续登场，具体内容与上线时间请以游戏内公告为准。 【英雄调整】 全英雄普攻与暴击体系重构：暴击伤害率提升，攻击速度上限由2.5次/秒提升至3次/秒；攻速收益率不再按近战/远程一刀切，每个英雄将拥有独立的攻速收益率。这将从根本上改变暴击类英雄的出装思路与伤害节奏。 射手专题调整：伊泽瑞尔、卡莎、图奇、卢锡安、凯特琳、德莱文、厄运小姐、莎弥拉、泽丽、金克丝、阿克尚、库奇、霞、崔丝塔娜、希维尔、薇恩、艾希、烬、赛娜、芸阿娜等英雄围绕新暴击体系重做数值与机制，多名射手基础攻击力上调、技能伤害改为与暴击率/暴击伤害率联动，射手生态整体重塑。 其他暴击英雄适配：亚索、永恩的溢出暴击率转化系数下调，普攻与1技能暴击伤害调整为常规暴击伤害的90%；佛耶戈、泰达米尔的技能公式同步适配新暴击体系，泰达米尔基础攻击力大幅上调并重做战斗狂怒。 英雄耐久度调整：盖伦、亚托克斯、蕾欧娜、布隆、锤石、奥恩、塞拉斯、雷克塞等英雄的基础生命值、成长生命值、护甲与魔抗获得重新调配，整体上强化中后期成长、削减前期硬度，具体名单详见官方公告。 其他数值调整：奥拉夫生命值成长上调、技能系数下调；沃利贝尔被动伤害曲线调整。 【装备改动】 射手装备大规模更新：新增海克斯镜片C44、育恩塔尔荒野箭、岚切、疾射火炮、猎魔人弩箭、不朽盾弓、斯塔缇克电刃，以及十字镐、缚炉之斧两件中
Questions
Does League of Legends Mobile (China) work on iPhone Duo?
It works, but with black bars. League of Legends Mobile (China) 7.3.3.2818 is built with the iOS 26.2 SDK, so iPhone Duo runs it in a phone-sized window on the inner display.
Does League of Legends Mobile (China) work on the outer display?
Yes. iPhone Duo's 5.4-inch outer display behaves like a regular iPhone screen, so every iPhone app works there as usual.
Can I use League of Legends Mobile (China) in Split View on iPhone Duo?
Yes. On iPhone Duo every app can be placed side by side with another app on the inner display — developers don't need to opt in. How comfortable it feels at half width depends on the app's layout.
Why does League of Legends Mobile (China) have black bars on iPhone Duo?
Apps built with the iOS 26 SDK or earlier run in a phone-sized window on the inner display, and iOS 27 builds can still leave some space empty. The bars disappear once the developer rebuilds the app with the iOS 27.1 SDK — you only need to update the app.
When will League of Legends Mobile (China) fill iPhone Duo's inner display?
When its developer releases an update built with the iOS 27.1 SDK or later. We read the SDK of every new version of League of Legends Mobile (China) within about a day of its release and update this page.
What can I do about the black bars until then?
Use League of Legends Mobile (China) on the outer display, where it works like on any iPhone, or put it in Split View next to another app on the inner display so less of the screen goes unused.
