TheXiaomi Redmi 1S, code-namedarmani HM 1S, is a smartphone released in May 2014, developed by theChinese companyXiaomi Inc. It is a part of theRedmi series ofsmartphones, and succeeded the Redmi 1. Visually similar to its predecessor, it comes with a 4.7-inch screen, a quad-core 1.6 GHz Cortex-A7 processor and runsAndroid version 4.3 (Jellybean), bundled with the proprietaryMIUI v5 user interface,[1] which can be upgraded to MIUI v9 based onAndroid 4.4.4 KTU84P.
Noted for its low price (₹5,999 (US$69) inIndia), the Redmi 1S was an extremely popular and a demanded smartphone. Xiaomi opted to sell the smartphone online in order to comply with their minimal capital input.[2]Flipkart was the exclusive retailer of Redmi 1S in India. The company discontinued the smartphone's sale in India in favor of the successorsRedmi 2 andRedmi Note.
The Redmi 1S offers Android 4.3 Jellybean, with proprietaryMIUI v5 custom graphical user interface pre-installed by the manufacturer, and can be upgraded to Android 4.4.4 (Kitkat) with MIUI v9 viaOTA. The Redmi 1S comes with a factory-unlockedbootloader, allowing users from the outset to further develop the OS and "root" the device, or gain legitimate privileged control in Android's subsystem. Software-development community XDA-Developers was among the first to release acustom rom and kernel for the phone, and since then the phone can unofficially be upgraded to newer versions of the Android OS family and other aftermarket versions. The Redmi 1S has received many unofficial operating systems such as:LineageOS 18.1,CyanogenMod andMokee OS.[3][4] Itskernel isopen sourced and is available to developers for modification.[5]
The Redmi 1S has a plastic chassis that is 5.39 in (137 mm) long, 2.72 in (69 mm) wide, and 0.39 in (9.9 mm) thick, and weighs 158 g (5.6 oz). The screen is a 4.7-inch IPS LCD capacitive touchscreen, supporting 16-million colors at a resolution of 1280 x 720 pixels, equating to around 312 pixel-per-inch density. The device features a Qualcomm Snapdragon MSM8228 which comprises 1.6 GHz Cortex-A7 quad-core central processing unit (CPU) and an Adreno 305 graphics processing unit (GPU), in conjunction with an accelerometer, gyroscope, compass and a proximity sensor. The device is also equipped with 1 GBRAM and 8 GB internal storage, supporting microSD expansion up to 64 GB. Other features include a microphone, GPS, an 8-megapixel rear camera with auto-focus and LED flash, and a 1.6-megapixel front camera. The rear camera is capable of recording videos at 1080p resolution, while the front camera supports 720p resolution recording. The rear of the smartphone features a plain plastic surface with a brushed metal Xiaomi logo at the center-bottom of the rear cover. The smartphone is shipped with a 2,000 mA AC power charger, for charging its 2000–2,050 mAh(min/typ) battery.
