Yes I m also facing same problem can u give such idea bcoz it's not even 11 days old
Hey guys i found the solution it may help u r someone who needs it
Recently I had same problem that was experienced by all the Lenovo users. I had visited this website today itself by searching from Google Search.
I also could not see any solution by any of the users.
I had tried to understand from where this flash sign of Volume appears. I thought it was coming through the app called SIM TOOL KIT. Now the SIM TOOL KIT does not belong to SMARTPHONE makers but NETWORK providers. In my case it was belonging to VODAFONE. It could neither be FORCE STOPPED neither removed from Smartphone.
I just opened the app and there was a menu called VODAFONE SERVICES. Under VODAFONE SERVICES there were many sub menus out of which first was FLASH. I just clicked on FLASH . Under FLASH menu there were sub menus like Activation, Service Info, My topics and Alert.
After clicking on ALERT I could I could see sub menus as ACTIVATE AND DEACTIVATE. I clicked on DEACTIVATE when the system ask whether you wish to deactivate . Just click OK and the problem disappears.
Thank you.
