Hi I have several issues with my otherwise awesome Acer Liquid Z530 (8 GB variant). First of all I need to be able to block calls. Acer themselves stated in their "Acer Tutorial" app (the one with letter "i" in green circle icon), that to block calls, we need to press three dots menu within desired contact and select "block calls". But there is no option like that there. I know there are other options like apps but they always tend to ring at least once before blocking and sometimes doesnt block call at all, which native call blocking could solve by my opinion.
Other issue is that some floating apps namely browser, maps, notes, crashing quite a lot. Some of them somewhot work over home screen with all other apps closed, but when i for example try to open link from skype with floating browser it crashes immediately, thus prety much rendering floating browser useless.
Latest issue I had encoutered is that i cant log in to "Acer Care Center" app, it always states that i dont have interenet connection, which I am realy sure I do have.
Thats all for now (I hope) thank you for your support
Have a nice day
