Hi
tusharguin29,
1) SOUND QUALITY TOO LOW
Sound quality is expected to be improved through a future firmware update.
We will notify you once it is released.
2) CHARGING TIME HEATING ISSUE (USED ORIGINAL CHARGER)
About overheat device heating issue in regular use, we suggest that you avoid running apps that may use much memory for a long time, for example, 3D games and video.
Also, it's recommended that do not use your phone/tablet while it is charging.
Please also try removing the background apps in recent app list, and check again.
Please also check if this behavior appears in safe mode: How to Enter and Exit Safe Mode on Android phone ? | Official Support | ASUS Global
For more information on improving the overheating behavior:
https://www.asus.com/support/FAQ/1011555/If the problem still appears, please tell us:
Which zone is heating up (back/upper/middle/lower)
The app/ app version you're using
Were you using the app and charging at the same time? Or only charging? Only using the app?
How much is the ambient temperature when this appears
About how much is the temperature of the phone
3) NOTIFICATION LED NOT WORK WHEN RECEIVED NOTIFICATION
Please make sure you've enabled "blink light". Settings>Apps&Notifications>Advanced>Blink light.
If the behavior still appears, please tell us the app/app version/ notification type/ detailed steps you performed/ screenshot or short video.
How often does this behavior appear when you receive a notification?
5) CAMARA APP FLASH ON ALL TIME WHEN OPEN SELFIE SECTION
We didn't find this behavior on our phone here. Please make sure you've disabled the flash by tapping the lightning icon on the camera when you're using the front camera.
If the problem still appears, please show us a short video of the problem, and tell us how often it happens.
6) VODAFONE VOLTE NOT WORK
Sorry, VoLTE support will vary by country/operator. After checking with relevant teams, Vodafone VoTLE is not supported on ZB601KL.
7) SCREEN OFF TIME BATTERY DRAIN HUGE
After upgrading to Android 10, there will be new optimizations to enhance system performance (e.g. touch booster,...), and the chemical properties of Lithium ions may cause the battery capacity to decrease gradually over one year of use. Therefore, the current experience may not be the same as your previous experience. If the current experience is affecting your normal use, we would suggest that users downgrade to Android 9. You may also visit the service center to check the battery health (life cycle remain) and make sure if a new battery replacement is needed for your device when it is over one year of use.
Thanks for your understanding and support for ASUS products.
Thank you.
🙂
