Hi There??.Now im gonna share you my experience about these phone.
Samsung z4 is worth to buy because it has 128 microSD up to 128GB you can download tons of app, games, pictures videos and anything with these phone. It is a soft touch so apparently it will not give a problem in typing texting. It is very smooth and I think it is very affordable and I promise you you wont regret .
Its not about how big your phone is its about the feeling you get about the phone. The phone that fits you the phone that is enough with you.
Not with other who demads it because of social media and what they see .
I would like you to reccomend it for you??.I think its the best.
