The rankings were limited to the top 10 OEM Android brands which provide software and security updates, with devices older than three years and Android Go variants not considered.
Counterpoint said in a white paper that Nokia phones were first in all price tiers when it came to the speed of providing software and security updates.
HMD was also joint first in providing the latest software updates across its range and led other brands in build quality by applying tougher tests than the industry average.
Counterpoint vice-president and research director Peter Richardson said: "The COVID-19 pandemic has made the world even more digitally connected than before. With smartphones being devices that are always-on and connected, they are more vulnerable to cyber attacks which are growing both in frequency and severity.
"This makes software and security updates for Android smartphones a critical aspect.
"Due to the pandemic, there have been changes in the work environment with many more people working remotely. This situation calls for an enterprise-grade security solution for data security, to block malware, and to prevent things like phishing attacks.
"For the second year in a row, Nokia phones have topped our rankings in providing the most comprehensive software and security updates and they have the highest share of portfolio recommended for enterprise use.
"The performance of Nokia phones continues to be a competitive advantage over the rest of the smartphone brands in the Android ecosystem. Ninety-eight percent of Android smartphone brands still offer inconsistent software and security updates or none at all.
"OnePlus also did well by providing faster software updates to all its devices currently selling in the market, followed by Samsung and realme.”
Counterpoint global content manager Ritesh Bendre said some brands concentrated on keeping their products up-to-date, while others only issued software and security updates after considerable delay.
"Regular software and security updates help not just the overall device experience, but also help devices retain their value over time," he pointed out.
"Surprisingly, there are top 10 smartphone manufacturers that don’t have any clear strategy to inform customers whether their devices are eligible for security and software updates.
"We think this issue will become increasingly important as consumers keep their smartphones for longer and rely on them more. Nokia and OnePlus devices have done well here.”
Counterpoint associate director Tarun Pathak noted that build quality was evaluated based on several criteria, including product robustness, force measurement, drop and impact, fatigue, wear and scratch, thermal tests, moisture and liquid tests, and other qualitative and quantitative aspects.
"We found that Nokia phones undergo tougher tests than the industry average," he said.
"We therefore concluded that, when considered alongside the faster software and security updates, the strong build quality means Nokia phones will last the test of time which is increasingly important at a time when global device replacement cycles are getting longer, now approaching 30 months.”
