I updated my Xperia L to 2.17 yesterday,and today,about a few hours ago,my phone lost all signal.
How it happened was weird though-
I first noticed this when i tried to make a call and it wouldn't go through.At that time,the signal bars were full.
Then,i tried to send a text message.Same issue-not delivered,with the signal bars still full.
I thought it could be network issue and put the phone into airplane mode and out of,about 3-4 times.still the signal bars are full,but no call/message was going through.
Fed up,i rebooted the phone twice.Same status!signal meter is showing full,but no calls/messages going through.
Then,after 5 minutes,the signal meter showed no signal-emergency calls only.
then,about half an hour,network came back up and i was able to use the phone as usual.
It couldnt be a provider issue as another phone with the same provider sim worked fine.I also had plenty of talk-time left so,its not an issue of that either.plus,i was in direct line of sight of multiple towers.
for some background-the sim is about 4 years old.plus,to get 3g working on my phone,i had to play with the settings a bit and it could only be activated after my service provider did some hocus-pocus.since then,i got fed up with their ridiculous prices and shifted back to 2g.
The same sim was in use in a hardy nokia1100 and then a Nokia 6020 till a month back,when i got the XL.and never have i faced such an issue before.
Is it a phone issue?I checked
View attachment 11741the battery usage-it shows the network issue in red.
Initially,i neglected this in the battery page-this is not the first time the battery page shows network was dropped.it has happened multiple times before,only-this time,i saw it happen live when i was using the phone.so,its not a sudden issue and has been there for a bit of a while.but its not for a long duration.short periods of signal loss and its back up again.
Another fault i noticed sometimes-when i receive a call-it drops off and i have to dial them back.
However,if i were to make the call,it works just fine.happens very rarely though.
so,do i change the sim or go to the service center?is it a radio/antenna issue?
