But now the correctly tapped letters aren&rsquo;t even registering\n          correctly.<\/p>\n<p>[&#8230;]<\/p>\n<p>iOS has bugs across the whole ecosystem. But having the keyboard,\n          the thing I interact with hundreds of times a day on my primary\n          device, get progressively worse with every update is absolutely\n          maddening.<\/p>\n<p>I randomly tried Android again for a few months last spring. Using a\n          functioning keyboard was revelatory.<\/p>\n<\/blockquote>\n\n<p>I had to turn off autocorrect because it kept changing correctly spelled words&mdash;that are in the dictionary&mdash;to complete nonsense: camel case words with numbers mixed in, as if they were usernames from Reddit.<\/p>\n\n<p><a href=\"https:\/\/www.macworld.com\/article\/2952872\/heres-proof-that-those-iphone-typos-you-keep-making-arent-your-fault.html\">Filipe Esposito<\/a>:<\/p>\n<blockquote cite=\"https:\/\/www.macworld.com\/article\/2952872\/heres-proof-that-those-iphone-typos-you-keep-making-arent-your-fault.html\">\n<p>I filmed a slow-motion video while typing a few phrases, and the bug showed up immediately. In one test, I repeatedly typed &ldquo;thumbs up,&rdquo; and several times the system replaced letters I had correctly tapped. In one case, pressing &ldquo;H&rdquo; produced a &ldquo;U&rdquo; instead.<\/p>\n<p>[&#8230;]<\/p>\n<p>At first glance, it&rsquo;s easy to blame auto-correct, but that doesn&rsquo;t seem to be the reason. The keyboard registers the correct tap, and yet the output changes afterward, meaning the issue likely occurs after input recognition, not before.<\/p>\n<\/blockquote>\n\n<p><a href=\"https:\/\/x.com\/Appyg99\/status\/2023746665338073291\">Apoorva Govind<\/a>:<\/p>\n<blockquote cite=\"https:\/\/x.com\/Appyg99\/status\/2023746665338073291\">\n<p>As a service to the society, I just want to go back to work at Apple for 1 week so I can fix whatever garbage dictionary they&rsquo;re using for word prediction on their keyboard.<\/p>\n<p>Look at this effort of mine to type the word &ldquo;barbaric&rdquo; using the swipe keyboard.<\/p>\n<\/blockquote>\n\n<p>Previously:<\/p>\n<ul>\n<li><a href=\"https:\/\/mjtsai.com\/blog\/2025\/10\/24\/what-happened-to-apples-legendary-attention-to-detail\/\">What Happened to Apple&rsquo;s Legendary Attention to Detail?<\/a><\/li>\n<\/ul>\n\n<p id=\"ios-18-and-ios-26-autocorrect-update-2026-03-19\">Update (<a href=\"#ios-18-and-ios-26-autocorrect-update-2026-03-19\">2026-03-19<\/a>): <a href=\"https:\/\/x.com\/codyaims\/status\/2033813087124644236\">Cody James<\/a>:<\/p>\n<blockquote cite=\"https:\/\/x.com\/codyaims\/status\/2033813087124644236\">\n<p>I found my 9 year old iPhone X and decided to charge it to test a few things<\/p>\n<ul>\n<li><p>There&rsquo;s no lag switching between apps \/ screens<\/p><\/li>\n<li><p>I had zero typos while typing 6x faster.<\/p><\/li>\n<\/ul>\n<p>Returning to my &ldquo;new&rdquo; phone, I had 7 typos while just writing this post<\/p>\n<\/blockquote>\n\n<p><a href=\"https:\/\/9to5mac.com\/2026\/03\/18\/ios-26-4-fixes-iphone-keyboard\/\">Chance Miller<\/a>:<\/p>\n<blockquote cite=\"https:\/\/9to5mac.com\/2026\/03\/18\/ios-26-4-fixes-iphone-keyboard\/\">\n<p>iOS 26.4 specifically focuses on fixing a bug where characters on the keyboard appeared as if they were tapped, but were not actually inserted.
