Not all phone cameras can take 4K photos, but most can: Generally, cameras with resolutions greater than 10MP take photos in 4K or higher, and even the main, ultra wide-angle and telephoto cameras in the iPhone 12 lines are all 12 MP. Users need to make sure their phones’ cameras take 4K and higher resolution photos with the highest quality. This can be set in the camera app settings or in the phone settings app, such as in iOS (Settings> Camera> Formats> High Efficiency).
The other side of the update now allows users of the Twitter mobile app to view 4K photos on their phone, but given the number of smartphones that actually have displays at resolutions reaching 4K, you probably won’t be able to see them. photos with that sharpness on your device.
Most phones released today have Full HD (1920 x 1080) screens, although the first number may be larger if the phone is longer), which are a quarter of the resolution of 4K (3840 x 2160) screens. Even flagship phones like the Samsung Galaxy S21 Ultra 5G have higher versions of Quad HD (2560 x 1440) resolution screens, while Apple’s phones have their own unbalanced resolutions that lie somewhere between Full HD and QHD (iPhone 12: 2532 x 1170), but they’re all below the 4K threshold and won’t be able to see 4K photos in their full glory.
Only a few phones sold today have a 4K screen, including the Sony Xperia 1 II. Of course this doesn’t work Twitter’s new mobile app functionality is useless – you’ll still be able to upload 4K photos for all your fans to home computers, but they’ll need to have their own 4K and fancier displays to see them at full resolution.
