Am getting pi**ed off with these computer automated telephone calls that are are basically scammers, ringing you once then waiting to see if you ring them back at a huge cost. Now I understand those that have iphones can block them all, but what about android phones? I have an app called Call Control but will only block three numbers. The majority of them are 0843, 0161 and sometimes +44843 numbers and this is now happening 6-8 times a day, and now I turn off at night. Is there no legislation against this. Just had another one as I type this. Anyone with info on how to block all numbers on an Android.
