Hey there Socrats
I am really sorry Socrats that you have had to go through this it sounds like your in for a bit of a rough ride and I really hope it is for a short time and the relationship between you and your Aunt is not permanant.
I don't mean to insult you at all with this question and it is of real and geniune concern but maybe you should get a job of 1 kind or another and save up enough Money to buy your own Android device?
If you are old enough to be employed then I highly recommend you get an income - and it does not have to be a very high income job at all, just enough to purchase your own Cell phone once you have saved up enough.
It will make you feel acomplished or proud of yourself.
Then my second bit of advice is to download the Bill of Rights / Human Rights and try your best to explain Human Rights to her. However... I really recommend you do
not go to a lawyer... that could have a bad impact on the relationship between you and your Aunt espicailly if she is paying for your accommodation then sadly you might have no where to stay however sad that may be.
Never burn your bridges is a lesson I have learnt pretty well in life.
My third bit of advice is do you have any close family / friends that you can go to to get some help?
And lastly Vinsaity93 actually had very good advice and could be the best adviceof all.
When Vinsaity93 recommended telling a "white lie" it is actually very good advice.
This way you
1) don't destroy / disrupt the relationship you have with your Aunt and
2) You get your phone back.
3) Everyone is happy
Telling a white lie can do a crap load more good than bad in most situations... espicially when it falls on deaf ears.
And it sounds like your very head strong so I am sure you will make a good choice.
Keep well
Regards
Stinky
