Hello dev/s, i just wanted to confirm that the app works on hyperos 1.0.9, on mi 11 lite with android 14. I just had to reboot the device immediatelly after the mtz apply and the theme is ok after 2 days. The only situation is that when i go on heavy gaming , i have to re-apply it afterwards cause of limited ram (7.3 gb). I think it's better on newer brands. Nevertheless, i'm satisfied with the results. Keep it up!

I just hope this application can develop further, because I hope the theme I imported will become permanent :) Because it's a hassle if every day I go back and forth to the application almost 30 - 40 times to re-import files....:(

Hey, this is for whoever wants to install a theme for your phone. PLEASE CREATE A BACKUP OF YOUR PHONE I got bricked out of my phone and completely locked unable to switch on my phone. It shows a blank screen and nothing else. I had to do a factory reset to use it so PLEASE be careful.
