After a brief testing period, Twitter's iOS and Android app now allow users to upload and consider 4K images, consistent with a politician company statement. This lets everyone tweet images within the higher resolutions that their phones’ fancy cameras are capable of shooting. 

Twitter initially allowed select users to undertake this call in March, but now it’s hospitable to all users of its Android and iOS apps as of today. You’ll need to change your preferences to upload photos in 4K – head to Settings and Privacy > Data Usage > High-Quality Image Uploads and choose whether to permit photos up to 4K to be uploaded using your mobile data or simply over Wi-Fi.

Time to Tweet those high res pics –– the choice to upload and consider 4K images on Android and iOS is now available for everybody. To start uploading and viewing images in 4K, update your high-quality image preferences in “Data usage” settings. 

Not every phone camera can take 4K photos, but most can: broadly, cameras above 10MP take photos in 4K or greater resolution, and even the iPhone 12 line’s suite of main, ultra-wide, and telephoto cameras are all 12MP. Users will need to confirm their phone cameras are taking the highest-quality 4K-and-higher-resolution photos, though, which may be toggled either within the camera app’s settings or nested within the phone’s settings app, as in iOS (Settings > Camera > Formats > High Efficiency).

The other side of the update now allows Twitter mobile app users to look at 4K photos on their phones – but given how few smartphones even have displays with resolutions reaching 4K, you almost certainly won’t be ready to see the photos at that sharpness on your device.

Most phones released today have Full HD displays (1920 x 1080, though that first number could be greater if the phone is taller), which are 1 / 4 of the resolution of 4K (3840 x 2160) screens. Even flagship phones just like the Samsung Galaxy S21 Ultra 5G have taller versions of Quad HD (2560 x 1440) resolution screens, while Apple’s phones have their own oddball resolutions somewhere between Full HD and QHD (iPhone 12: 2532 x 1170) – but all are below the 4K threshold, and won’t be ready to see 4K photos in their full glory.

Only a couple of phones sold today have 4K displays and include the Sony Xperia 1 II. That doesn’t make Twitter’s new mobile app feature useless, in fact – you’ll still be ready to upload 4K photos for all of your fans on computer reception, but they’ll get to have their own 4K-and-fancier displays to ascertain their fully resolution.
