how to install?

Hello. There is a suggestion to add the generated contacts to a specific group. This will allow you to sort and hide fake contacts, which will also allow you to avoid generating contacts by mask.

OP7TPro with A11 here.

Need to report this app is absolutely useless. Let's start from practical part: started it, pushed "create", granted permisssions - and... nothing. I waited abouth half an hour - n.o.t.h.i.n.g. Rebooted - NOTHING!
Now - funny part: I decided to uninstall this useless piece of code. Aaand - the icon remains! Only reboot leads to cleaning the crap, but I had to set calls record function as it recognized ?new SIM card" for some reason.
So - from practical point oif view - the app simply DOES NOT work.

No - from theoretical point of view: I have about 600 hunderd so you will posion - how much? 50? 100? Will people who sell contacts care about 15% non-reliable part? I don't think so. Will I have issues finding correct names scrolling contacts with a number of fake people? Yes.

So - as I said - USELESS.

I would be really happy with interception calls for contacts with whitelisted apps and blacklisted apps - providing different contacts. I even ready to install Magisk/Lsposed hooks for that. But as for now this app look like a child toy.

Sorry - but I think I deserved having an opinion after an hour of test of this piece of code.

I have an idea for enhancement of the contact generation principle. It is hard for the app to identify fake contacts it has created, e.g. for later removal. Using a certain name pattern (all names starting with the letter "z") is simple, but the poisoned database also can be easily cleaned. So I would suggest the user to enter a 4-digit PIN at the startup of the app. All contacts will be coded with that PIN so that later fake contacts can be identified only if you know that PIN.

How to do it: Maintain two lists of 1024 names, 1024 surnames and 1024 last names. Now randomly combine them, (gives 20 bits code) and also combine them with the 12 bits generated by the PIN. Together we now have a 32 bit value for each combination. Now calculate a hash from these 32 bit (lookup table or 8bit checksum). And discrard all combinations which have a hash other than one speicific, say 0. Then all fake contacts can be identified and the chance of a false positive (to be removed from the contact list) is 1/256 (in this example with a 8 bit hash) which probably is good enough. One can use a 6-digit pin to further bring it down.
Lists with 1024 Names can easily be obtained/generated. One even can use customizes list according to the nationallity or so.

Hi, I like the idea of this App. However is crashes on my (rather old) Android Phone SAMSUNG Galaxy Alpha at start.
I use the f-droid version 1.6. It works on more recent phones (Android 9).

I love your ideas, I installed it on a fake phone I use for WhatsApp.
Can you integrate your application with https://thispersondoesnotexist.com/ ?
This would allow to create a fake contact photo too!.
Thanks!

i like this app, but the problem with it is, it generate a lot of contacts with the same name, even if it have 100 names, it will generate a lot with the same name.
