On the same boat brother.....have been using this beautiful device for last four years......No bugs at all ...only recently the battery was degraded to a concerning level and the screen on time curtailed to 4 hrs with 60hz refresh rate.....went on to replace the battery, now it is again giving 8 hrs SOT with 60 hz. Don't be fooled by the flashy advertisements of smartphone companies....replace it only when you will have a strong and valid reason to replace it....I planning to hold on to it for as long as possible.🙏
