Exactly!!! If someone doesn't have any info on how ROMs work and how security patches are incorporated to build of each ROM, one shouldn't be creating useless threads pointing fingers and do should first learn a thing or two about ROM development first.
Subir you don't understand software terms that you agree to while purchasing a phone. Nokia committed that 6.1+ being android one device will receive regular security patches. No company will say outright that we will deliver the patch on 5th of everyone at 11:59 pm. And being called for doing advocacy for Nokia, I certainly don't care if Nokia misses a deadline as long as the update is not buggy as other brands.
Google can certainly afford to provide patches on above-mentioned dates as there portfolio is not as huge as other brands. Not being sure on what exactly Nokia is stuck m going to shut up!!
Can the Battery drain be improved and optimized in future updates in Nokia 6.1plus?
Nokia and HMD global are making everything suspense, regarding security updates, regarding android P, regarding release of FOTA for camera or other bugs. Nothing they are revealing. Dont know what they are planning of?
