Hello everyone, I bought my Xiaomi mi4c a few months ago. It used to get an update every week or so, But unfortunately weekly updates stopped after 6.1.28. About Phone: Android Version - 5.1.1 LMY47V MIUI Version - MIUI 7 by xiaomi.eu. 6.1.28 | Beta Is there a way to fix this without flashing a custom rom and voiding my warranty? Thanks in advance!!
