Network problem in Galaxy M30s.

[Sumitpatel]

After an update in Galaxy M30s, network difficulty stared as well as a sluggish data speed issue. Another thing carrier aggregation is not enabled. That's so soo rubbish.

I also use M30s, but I didn't found any such problem after the update!

Maybe some other issue?!?
Nevermind!

The June Patch Solved Majority Of These Issue.
Also You Be A Region Thing.
I Am Getting Excellent Speed on Airtel & Vodafone.

Carrier Aggregation Is Not Supported On Mseries Devices.

After June update you are getting 32mbps in 2g?

[RohanGhag]

That Was Due To Accidently Turned On Airplane Mode & Quickly Turned It Off.
Hence The 2G Symbol.
Anyways Here Is The Test Again
