Yer, indeed. It's very irritating trend...
And it'd be nice to find a sure way to protect Android phone form such annoying behavior, coming nor only from Dolphin, but form other similar apps too.
The device is rooted long time ago and I have some (alas far from full) control over it.
Tools, that I use, include
System Tuner (currently v3.0.8) and it allows to make some arrangements for "Start up" apps. And particularly, Dolphin Browser is cleared from event
BOOT_COMPLETED there. But it still start itself all the times... And I can't find out the reason - why. What does trigger that?
One more thought related to Dolphin. Perhaps I need to find a better browser. Here is yet another reason for that - Dolphin Browser always tries to get IMEI of my phone. It doesn't need to get that unique ID to operate as a browser, that's for sure. The only reason for getting IMEI is to track my device. and I surely don't need that. I always block these attempts with LBE Privacy Guard.
