Xiaomi recently released a new software update for its MIUI operating system to fix the overheating problems of the Mi 4i but also ended up adding more problems to the device. The patch, called V18.104.22.168 LXIMICD MIUI repair patch, was around 804MB in size.
According to Xiaomi, the patch included a new heat management algorithm that improves the device’s voltage and frequency control along with the number of cores running depending on the device’s current chipset temperature. The company claimed that the new update would eradicate with the Mi 4i’s overheating problems.
However, soon after the update was released, reports starting surfacing saying that after the update is downloaded and installed on the Mi 4i, the devices’ data connection becomes unstable, the battery life is cut in half, and the device’s camera stops working properly.
Because of these reports, Xiaomi has now pulled out the update and announced that a new update, version V22.214.171.124 will be available sometime within the next week. Sadly, those who have already updated to broken V126.96.36.199 update have no choice but to wait for the next update to come out.
The Xiaomi Mi 4i was released just last month and is currently available in India, Hong Kong, Singapore, and Malaysia. It is powered by a Qualcomm Snapdragon 615 1.7GHz 64-bit quad-core SoC, 2GB of RAM, and 3,120mAh battery.[source]
