After all these years, Notebookcheck still didn't learned how to put GPS tracks on the same map. There were some reviews which had it, so my hopes were high.

Also you need the true track which you will draw in the mapping software, because you know it, besides the reference device (Garmin) which itself can't be perfect.

Is it hard to have three tracks on same map?

For me, this is a quality device. My previous phone was the oneplus 6 - one of their last true "flagship killers". This does feel like a significant upgrade for me in many departments, albeit there are some  compromises. However, for less than half the price of a oneplus 10, I can live without wireless charging or IP rating (never been bothered) and the plastic frame VS metal is no issue. The only thing I miss is the 4k 60fps video. The main camera is great, not so the others unfortunately. The charging is amazing and battery life absolutely fine. Nice screen, smooth software, definitely a premium feel. Yes, the true flagships will be marginally better all round, but for less than half the price, this is certainly all I need.
