4K ULTRA APK: questions and answers
Can I install this APK over the version I already have?
Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.
Is the 4K ULTRA APK safe?
No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. It is signed with Android's public test key, which anyone can use. After downloading, check that the file's MD5 is 52eebe3536ed391136d549c52d850e88.
