I have been facing network issues a lot in M30s from July update... It seems to be fine and very next minute I don't get any transmition, speed or data.. I used to think this is because of network provider I.e airtel so I raised a complaint on this too..
With no resolution yet and many calls with CC I decided to check with another device and here are the results...
Seriously? 4yr old J7 prime performing better.. Not even single issue or drop in whole day of my test..
Also you can Lte- A, 4CC and 2CC.
I contacted airtel on this too their reply is " Sir, we are providing CA even in band 40 unlike other networks who provide it in band 66+" that's the reason you are seeing those in J7 prime with supported band 40..
Then why I'm not seeing 4g+ ?
" Sir, network and CA is in our hand 4g, lte and + depends on device, manufacturer and how they tweaked it in their UI "
So here comes my M30s
With whole day test not a single time I saw bandwidth falling below 2300 in J7 prime and not a single time above 900 in M30s..
In same location, same place, same area why J7 prime is performing better than M30s?
Here are the hardware specs of both..
1. I didn't blurred location so everyone should know test conducted in same place
2. I used same airtel sim in both devices
3. Network issues are from last update and became serious from 15days.. 10days back I reinstalled firmware by visiting service center hoping it may fix.
