EDIT Today, I have tested the new builds of Xiaomi.eu on Mi4, Mi5, Redmi 1S and Redmi Note 3 Pro (kenzo). And I have to say, Xiaomi.eu have come a long way... The performance is much better, and a clear improvement can be seen when comparing it to the official ROM, as the Xiaomi.eu is faster and with smoother animations. Congratulations on your hard work towards improving this ROM! END EDIT A while ago I posted this thread: http://xiaomi.eu/community/threads/miui-v6-weak-performance.27615/ As I had no feedback, and many users were complaining about the poor performance of this ROM on the Redmi 1S, I went and tested the original from Xiaomi servers. And I got really surprised: the performance was very good! As this ROM has no Portuguese, I went and flashed the ROM from the MIUI Forum of my country: MIUI Portugal. And, for my even greater surprise, despite it being the first release of MIUI V6 for Redmi 1S (5.4.24), the performance was GREAT! Great in a way I have never seen this device move around. I am saying this to point out some issues I have seen many people complaining. There is room for improvement here. Cheers to all! And thank you for your hard work.
