User opinions and reviews

  • Megahoggy

i have version with 4 GB RAM and its also works very well in 2025. so i think its consecuences of optimisation OS with the processor 9611 by Samsung

  • Gnusmas

my cousin using this smartphone for over 2 years already, it's 2025 and it still works really well, despite not so great Exynos 9611 it still works without lagging, probably 6gb of RAM helps.

  • Zakaria

Sorry, but you can't even install it if you wanted to. The Canadian model (that I also have) has a locked bootloader and it is unable to be unlocked, therefore you are stuck on the one ui 5.1 update
