I have seen that every smartphone that used to be flagship device start facing lag after a span of time. why does the same RAM, same CPU becomes slower over the years. Taking example of Samsung device from S3 to S6.
Samsung claimed S3 as most powerful device on May 2012
but now its not even having power why does it happen irrespective of the android updates.
similarly Samsung galaxy S4 now lags and freezes.
Are the new software updates and apps this heavy that the older device cannot handle?
