After a brief trial period, Twitter’s iOS and Android apps will allow users to upload and view 4K images, according to an official Corporate statement. This way, everyone can tweet pictures in the higher resolutions that their phone’s fancy cameras can capture.
Twitter initially allowed select users to try this out in March, but it’s now open to all users of its Android and iOS apps starting today. You need to change your settings to upload photos in 4K. Go to Settings & Privacy> Data Usage> High Quality Image Uploads and choose whether to upload photos up to 4K with your mobile data or just via WiFi.
Time to tweet those high resolution images – the option to upload and view 4K images on Android and iOS is now available to everyone. To start uploading and viewing pictures in 4K, update your high quality picture settings in the Data Usage Settings. https://t.co/XDnWOji3nxApril 21, 2021
Not every phone camera can take 4K photos, but most can: On the whole, cameras over 10 MP will take photos at 4K or higher resolution, and even the iPhone 12 The line’s main, ultra-wide, and telephoto cameras are all 12 MP. Users need to make sure their phone cameras are there to take The highest quality photos in 4K and higher resolution that can either be toggled in the camera app settings or nested in the phone settings app, like in iOS (Settings> Camera> Formats> High Efficiency).
You can tweet 4K, but you cannot watch 4K on mobile devices
On the other side of the update, Twitter mobile app users can now view 4K photos on their phones. Given that few smartphones actually have displays with a resolution of 4K, you probably won’t be able to see the photos on your device with this sharpness.
Most phones released today have full HD displays (1920 x 1080, although that first number may be larger if the phone is larger), which is a quarter the resolution of 4K (3840 x 2160) screens. Even flagship phones like that Samsung Galaxy S21 Ultra 5G has larger versions of Quad HD screens (2560 x 1440), while Apple’s phones have their own special resolutions between Full HD and QHD (iPhone 12: 2532 x 1170) – but all of them are below the 4K threshold and won’t be able to see 4K photos in their full glory.
Few phones sold today have and contain 4K displays Sony Xperia 1 II. That doesn’t make Twitter’s new mobile app feature useless, of course – you can still upload 4K photos to home computers for all of your fans, but they need to have their own 4K and fancier displays to see them in full resolution.
