Hi jaycee42788,

"sim 1 lte 4g signal always drop from 100% to 0% and recover after 2 to 3 seconds", What do you mean by this? no 4G icon missing for 2-3 second and come back after that? or signal icon turn "x"?

If possible, please make a small video to show this problem. thanks

Yess it turn "x"  if i fix in 4g signal.. If the setings is in "2g 3g 4g mode" it change the signal in 3g mode because the 4g sudenly gone.. After 2 to 3 sec the 4g recover and the 3g signal become 4g again.

Sadly, this also is happening to me. I highly suspect this is due to the firmware.

See my thread here: https://www.asus.com/zentalk/ph/thread-118727-1-1.html

And one more, my fone replaced 2x in the store where i bought my zen3 all of the fone they replace having the same problem....hmmmmm

Hi jaycee42788,

Please tell me your mobile operator and the their supported LTE band.

Does it happen to any 4G SIM card? sim 2 has no problem right?

Please upload your video to online space and share the link here.

thanks

It happened to me too. I had my phone replaced once because the phone cannot decide which frequency it will connect. The signal icon switches from 4g to 4g+ very fast and it looks like it is just blinking until i took a video of it in slow mo. Then when 4g stabilizes, i cannot connect to the internet anymore. The H+ is even reliable because i can connect to the internet. With a newly issued device, the switching doesnt happen anymore but the problem when 4G connection shows is still there. I hope that it can be resolved by just a FW update and not a hardware issue.
