Xiaomi has pushed an over-the-air update for the Redmi 1S. The latest firmware version brings MIUI 5 v4.5 and brings a fix to several performance-related issues. One of the key issues that users report fixed is the occasional overheating of the device. With the new update the RAM handling is also improved - background apps are now given a shorter lease of life so they don't clog up your system. The update weighs in at 514.4MB and should already be waiting for you to download it. Xiaomi held several big sales campaigns for the Redmi 1S in India selling over 100,000 phones in seconds. The smartphone is offered for just $98 (INR 5,999), which considered its specifications is a spectacular price.
