Bluetooth 5.0 worked well with Motorola Pulse Escape earphones and with other smartphones while sharing files. I had no problems with other modules, like Wi-Fi, 4G LTE (Cat 6.), GPS with aGPS, GLONASS, NFC, USB type C with OTG and a 3.5 mm minijack.
I have no concerns towards the quality of calls - Nokia 7.1 is a solid model in this matter. It does not have problems with maintaining the coverage, everything is loud, clean and clear enough. The smartphone uses two SIM cards and we can choose which will be default for calls, texting and data transfer.
Memory and efficiency
After running the phone for the first time, the user has around 22.46GB left for apps and files – 30% out of declared 32GB of internal memory is taken by the system and preinstalled apps. We can of course place a memory card, though then we cannot use two SIM cards.
The unit is powered by an octa-core Qualcomm Snapdragon 636 with 1.8 GHz clock, supported by Adreno 509 GPU and 3GB of RAM. The efficiency was fine most of the time, but the smartphone had this irritating manner of not being able to respond to touch and the apps stopped. This happened on different occasions, with different frequency – there was no rule to it. Sometimes the camera app or Chrome closed up – the software definitely needs some updates. But maybe this is not a global problem, maybe this is just this particular device…
Nokia 7.1 is not a gaming smartphone, but it can run simpler and some more demanding ones. Titles like Asphalt 8 or Real Racing 3 or playable, though we cannot use higher graphics settings. I will add that the smartphone can heat up noticeably both while working and while charging.
