Galaxy S4 : Weird issue with magnetic sensor when mobile data is on
I have got a strange issue. First let me tell my story. My phone was fallen down 2 weeks before and the screen was broken but the functionality wise(including mobile data), phone was good. After 4 days, i replaced the screen from customer care, after that my sim card was not getting any signals. then i gave back to customer care and they fixed the problem with in 5 minutes. (On the same day night, my phone was fallen again to water, fortunately nothing happened, only the speaker was acting weird, it went OK after sometime)
Here the problem part starts, after the screen replacement, for the first time i turned on the mobile data on my phone. then magnetic sensor weird issue started. When the mobile data is on, the phone feels some magnetic noise and the S view cover display will flash through screen. This will happen like once in few minutes or in a such gap. it will just flash for 1 sec and go. When the mobile data is OFF/ in the flight mode, the issue never occurs. Any idea on this
I ran few tests, the results are in the attachment, i changed SIM and the behavior is same.
When i contacted the customer care, they said they have seen this issue and they can make it good by installing fresh s/w again. But my phone is out of warranty(so i need me pay for this) and i already tried cleaning my phone, wiping everything, installing fresh ROM's..
But nothing does the job
