appreciate your feedback.

you will need to get the GPS signal locked first before you could use any of the apps.

my friend is using webe on redmi note 4 snapdragon malaysia set and claim there are no such issue. but his wife's redmi note 3 is having GPS signal lost almost all the time.. and she's not using u mobile. can't remember which telco she was using.

Here's some new finding ...

both are identical redmi note 4 Snapdragon malaysia set

left is u mobile network, right is webe network

both phone just rebooted.

left phone is running with miui 8, right phone running with miui 9

u mobile setting: 4g network, not automatic select network
webe setting: 4g network, automatic

Obviously not.
