Xiaomi’s big battery budget devices for 2019, namely the Redmi 8 and Redmi 8A has officially received the green signal from Xiaomi for third-party development. The company has just released the kernel source code for both the devices, allowing developers to tinker with its code and develop custom ROMs for the device.


Xiaomi’s smartphones are popular for their extensive custom ROM development. Even the MediaTek powered Redmi Note 8 Pro kernel source code was released back in September. So, we can expect to see some new custom ROMs for the Redmi 8 and 8A in the coming months.
Xiaomi recently revealed that the Redmi 8 and 8A have a special sonic dust removal feature built-in. It’s essentially just a way to clear out the dust and gunk that tends to gather up in smartphone speakers, which is a fairly common problem.


According to Xiaomi, the Redmi devices achieve this by playing a custom sound designed to achieve the maximum amplitude of the speaker for 30 seconds. This allegedly gets all the dust out by pure force, without damaging the speaker we’d hope. It’s an interesting solution to a common problem.
Both devices have a large 5000mAh battery that easily offers two-day battery life. They share the same octa-core Snapdragon 439 processor inside with the Redmi 8 getting a 4GB RAM version while the 8A maxing out at 3GB RAM and 32GB of internal storage. Another major difference is in its camera setup as the higher-end Redmi 8 gets a dual 12MP   2MP shooter at the back while the 8A has to settle for a single 12MP sensor. Note that the cheaper 8A doesn’t have a fingerprint sensor.
