Signal Drops after every call !!! ICS, build 6.1.A.2.50

[sachin_arora]

Whenever I make/receive a call and after I disconnect the call signal gets drop for 10-12 seconds and I have checked my sim card with other mobiles(Iphone) but could not found any problem. Now I am pretty sure that the problem is with Xperia phone only and I checked number of people having xperia S and they are also facing same issue..

Xperia S : 4.0.4, build number- 6.1.A.2.50

Please suggest the solution because in India every other person is facing this problem with xperia S phones.

Thanks much,

Sachin

is this a micro SIM or did you trimmed your sim card?

I fixed it myself.. here is the solution:

If your are using GSM network change network mode to GSM only, go to settings->mobile network settings->network mode-> GSM Only.

By default it was CDMA(preferred)/GSM.

It should be GSM only.

Now I dont have any problem with network!!!!!!!!!!!!!
