Nokia has come a long way since morphing into HMD global. Their screens, batteries and cameras have greatly improved the only handicap is locked bootloaders especially on Android One flagships.
Oppo on the other hand have nice high-end phones. Their cameras are much better although their greatest weakness is battery life.
Overall Nokias have a solid build and some have full metallic bodies. Oppo is mostly plastic
One is Chinese the other one is European
“While our phones are designed in Finland, 100 percent of our devices are made in India.”
True, but the standards are strictly enforced, even Samsung has factories in China
Tiny Finland gave the world Nokia
Which is more pricier specs for specs?
Nokia is more price friendly than Oppo though; at this day and age anything below 64GB or 128GB issa NO, so you gotta dig deep…
I would rank battery life higher than internal memory capacity. Internal memory is highly priced thus I would prefer to pop in an SD card and manage data hoarding.
Back to the topic, Nokia one-ups (parent company makes OnePlus :D) Oppo with bloat-free stock Android, regular security and OS upgrades (Samsung- SMDH) and pricing.
