guys, recently my mate 30 which got GMS installed by staff after I bought it from a shop, have problem regarding mobile data & home fibre. Both data I use Celcom. The problem I found out is, when I use celcom home fibre at home to watch youtube, movie in fb, play online game using ps4 or even using hotspot to share home fibre for my pc, my mobile data will be deducted as well! it will deduct about 40mb every 15min I watch youtube. If ps4 online, it will deduct about 100mb for an 1hr.

Then I suspect this problem happened bcos of my GMS no more valid eventhough I still can use google drive, youtube or gmail. In order to proof that this is the reason, I put my sim card into my wife's mobile which got pre-installed GMS and start to watch youtube, fb movies & also play ps4 online using home fibre.

Then I checked my mobile data, it remain the same amount of data before my testing. I don't know whether u guys facing the same problem like me here?
