A Brief History of Krsnah Mobile OS

My phone model came out in 2015 running Android 5 Lollipop. The only upgrade that came from the manufacturer was Android 6 Marshmallow about 2 years later. By then I had already installed a Russian build of Marshmallow that worked pretty well for me.
I installed Android 7 Nougat at around the same time but the battery drained too quickly and the bottom half of the screen flashed on low brightness. Therefore I moved back to Marshmallow and stuck to it for almost 3 years.

Krsnah Mobile OS was based on from Android 6.0.1 Marshmallow after several tweaks. It was my first attempt at building a personalized mobile OS that catered specifically to my needs. It had major UI changes with a brand new launcher and was fully rooted and debloated. It still ran Google Play Services though.

Krsnah Mobile OS v2 was based on Android 8 Oreo. It was my first major upgrade since Marshmallow. It included MicroG. I experienced a major issue with the WiFi connectivity where the phone would go into bootloop when connected to the WiFi. I managed to fix the issue from the developer settings. The OS wasn’t as smooth as Marshmallow though. The battery didn’t last as long. I had to charge it everyday, sometimes twice a day, for long usage. It carried on the UI launcher and theme settings from Marshmallow. It couldn’t run Orbot though. And it couldn’t receive phone calls.

Krsnah Mobile OS v2.1 was another attempt at Android 8.1 Oreo that fixed the WiFi bootloop issues from a fresh install. It used a different launcher and several tweaks in the theme. It got rid of MicroG and ran barebones Android. There were some app incompatibilities and I had to use alternative apps to get around the problem. The major issue was that it kept hanging, all the time; e.g. while playing music, when receiving phone calls, when using apps etc
This problem had to be fixed urgently.

Krsnah Mobile OS v3 is the build on Android 9 Pie. It only lasted for a few minutes of use. Since I had directly tested the upgrade from 8.1 Oreo to 10 on my phone, the rollback to 9 Pie seemed like a letdown. Android 9 Pie seems like a half-baked version of 10. It seems like an incomplete OS with many missing features that were finalized in Android 10 release. While 9 Pie was certainly an improvement on 8.1, it wasn’t worth spending time on since I had already tested Android 10.

Krsnah Mobile OS v4 is built on Android 10. Doesn’t use MicroG. It runs smoothly, is quite fast and doesn’t hang or go into random bootloops. It is free from all bloatware. Battery lasts longer than the previous generations and even more so on standby. The UI launcher and theme are carried on from Krsnah Mobile OS v2.1
Had an issue running AdAway but it’s now fixed. Also couldn’t run Greenify as there seems to be an app incompatibility. Greenify would randomly close by itself. Haven’t done a comprehensive test on it but everything seems to be good at the moment.

With that said, I have also installed Krsnah Desktop OS v4.
This is the first desktop build that directly coincides with the Mobile OS build and with the same number of iterations.
More on this coming soon.
