To Convience my dad Asus ZenFone 2 is enough

I am using smartphone of my dad and mom from last 3 years. I like smartphone because of games but really I am getting upset when smartphone is hangs in between the game or not behaving properly. That time I thought better to through this smartphone and take something good. Even after that I got one tablet but still I was facing hardware and software issues. I am really frustrated with the running speed of smartphones and tablets. I told many times to my dad give me some good phone for games, but he is telling me every time that the phone is not for playing / gaming. Mobile is always for Text and Calls. Until and unless you will not have to make a call or send text I should not use mobile. That’s the learning from my Dad.
Still I am playing on my mom’s mobile and the mobile is very slow and as and when I am downloading games, my dad removing all games from the mobile and again I have to download and then again I need to play all levels of games, which I already completed before uninstallation by my dad. Now I am frustrated with the mom’s smartphone as well. I can’t download big games and even if I download this I can’t play. Mobile heats up and automatic shutting down.
Camera is also not with good quality. I need good camera quality to make my own home news. I am making good news for my home like a news anchor is delivering on news channel. I need a good smartphone which is having a good processor, good and big ram and big storage area. It should not hang, it should give me high performance.
I was discovering the mobile and I got to know that Asus Zenfone 2 is the worlds first mobile which is having 4 GB RAM. Unbelievable!! Now I can play big games and it will not hang. The following are the 5 good things for Asus Zenfone 2 by which I will convince to my dad – 
  1. It has 2.3 GHz processor, so It will have fast processing speed, I can play big games without any hassle.
  2. It has Good battery charging, normally smartphones are taking more than 2 hours for charging but Asus Zenfone 2 is taking only 39 minutes to charge 60% of battery. Its wow factor.
  3. I can take good photos in night with 400% more clarity without flash. It will help to get real pictures in night or in evening.
  4. Asus Zenfone 2 is having 4 GB ram and it will boost my gaming experience.
  5. It has good Rear camera of 13 Mega Pixel and Front camera with 5 Mega Pixel.
I think these 5 reasons are more than sufficient to buy Asus Zenphone 2 for my dad for me.
