@"lalit.sobhani" I am having a great time with this device and literally have very few demands from ASUS now (Dark mode, AR Core and some 6z camera features). They have solved almost every problem. After every update i clean cache and reboot my device twice or thrice (i suggest you do same for smoother performance as cache f**ks with the performance). Never faced any problem (fingers crossed). I am experiencing better sound with every update asus is pushing. It is better than any smartphone in this range. Except me many other users are also giving positive feedback. I use Evidson (in ear), Sony(Over the head), sennheiser (In ear) and JBL (Over the head) headphones and the sound is so spot on with my custom equalizer setting, i also use wide setting DTS (Try playing with the settings and you will find your perfect setting too). The UI is smooth, crisp and lag free. I dont use Asus launcher and have shifted to evie launcher long back (it leaves me with more than 3gb unused Ram). I am getting around 8 hours SOT and 30 hours standby backup (i dont play PUBG). I use pixelmaster (For wide angle and manual camera) and gcam (modded for 6z for point and shoot). All these tweaks give me a complete flagship experience. Try some of the above tweaks if you wish. No phone is perfect, we just need to find the workarounds for simple problems. Hope this helps
