i am xolo x900 user and facing a network issue since 2-3months now.
i had updated xolo from gingerbead to ICS long ago from www.xolo.in update file for 4.0 & after that also i had been updated a small file of some 27MB from the inbuilt app of mobile update.
Sorry! but i had found all threads & did not got the solution for my problem till now.
i dont use wifi so almost everytime i prefer mobile sim internet, so after taking xolo it was fine for 2months almost after that it started giving me problem about network issue.
The issue is as whenever i use internet from sim card on my xolo automatically the network vanishes & a "x" appears on the network signal with zero network.
After enabling internet connectivity just for 1-2min after i browse from any app as play store or chrome, android browser then network vanishes.
then i have to go to settings & select manual network, if its my luck then it searches for the network & i get it back again but after sometime again the same problem.
then next time when i search for network it shows "error while searching networks".
Then i have to reboot the handset after that only network appears.The issue is not at all with my vodafone sim because i used same sim in another handset & i get constant full network while using internet. Also i had changed my sim card to Docomo, still on that also i faced same issue.
But while calling or whenever my mobile is in no use condition that time there is no network drop issue.
Also i refered the www.flipkart.com which is official xolo marketing partner, on that xolo x900 section i read all comments, there also some users got network issues.
so after reading modaco thread i thought of rooting & downgrading that 27mb update, i succesfully did that but issue is not fixed. Also i reflashed the ICS image file, so that
it comes back to original state but still same issue.
Just last i had sent my xolo to authorized service centre, they told they will do some software changes, so they took 2weeks & gave me the handset in which they network issue is solved & some new options were added NFC smart card managing...i felt really my issue is resolved.
so inserted my sim & started using internet & here i was astonished to see the "x" again on my network bars with zero network. Ahhh it was so useless to give my xolo to service centre technicians.
what is the exact issue guys, why does network drops after switching ON internet?
Its like i took a wrong decision to buy my 1st android as xolo. inspite of that micromax canvas, xperia u, HTC desire X can be the best choice....in that price range.
