Problem: I do not have really a technical problem but I ran out of space on SD (32gb). Is it possible (did anybody succeed) to put 64gb in the phone? I read that if you reformat original exfat to old fat32 even 64gb sd can be read on sdhc devices as is the phone. Tried to do this on Sandisk 64sdxc but just lost the card, it dyed. I do not want to buy other card and to find out that is hardware incompatible with the phone. Any advice, perhaps the samsung sd is better. Otherwise I like the phone for its robustness and do not want to change it.
Problem: Well when I have not used my phone for a while, it automatically locks its sim card. Why? This is annoying. I do not receive messages before I activate my sim card again. Well when I have turned on my phone, it should remain on, until I decide otherwise. They shouldn't lock my sim card before I turn off my phone. How do I disable it?
Please

Even if your phone was advertised as being *free* on a contract, you are paying for it through your monthly payments and you have the same rights that you would had you bought any other electronic item - i.e. at least a year under the Sale of Goods Act.
You do not have to take what you are offered. Don't feel pressured into taking a phone you know nothing about. Check reviews online before you buy a new phone.
Make sure you understand how much you use your phone before you sign up to a new contract. If you only use 250 minutes a month, a 1,000 minute a month contract isn't going to be any good for you. Work out how much you need and look at plans around that amount.
