Hi, we have heard reports that most of the unofficial handler apps, specifically "imitation" and or "fraud", a "manipulated handler classes" to be exact, are not running and eventually collapses in almost all phone models. e.g. s60 3rd Symbian OS 9.1, 9.2 , 9.3 above, s60 5th, and others to mention.
( Notice: We advise this people not to release this type of apps for it is a disgrace to HUI applications, so as to the maker. )
This "posers" are not aware of this. The apps they generate is "unsafe" to your phones. Nevertheless, no development is expected to whatever they try to achieve. We do not treat this individuals as a threat to us, but we are in deep concern of you our beloved users, especially your device.
We encourage our loyal users to patronize the official HUI releases which we are confident to say "safe" various test are being implemented before lease and issues reported are instantly traced and fixed, "as we know what we do, and what to do."
