One major complaint on GSMforum against competitors like Octoplus or Z3X is server downtime. If their licensing server goes down, you cannot work.

According to GSMForum users, the December 2024 and January 2025 updates specifically addressed Android 14 locks and enhanced UFS (Universal Flash Storage) support—something competitors were slow to fix. umt card manager gsmforum best
