Got tagged by haruka091. I'll answer as detail as possible.

1. What are your favorite 5 apps?

I don't know if you counts PC apps as well, so I'll answer on both my laptop, phone (and maybe future phone if I studies well! XD)

#5: Asphalt 8: Airborne
Guessing you already know (my previous chapters), so I won't say much about it.
(Old photo below)

#4: Nox App Player
This is where I can play Android games on my PC. Pretty comfortable except for music games XD
You can find this on Google. Just type in "Nox App"

#3: Love Live! School Idol Festival
My favorite music game on phone. I became a pro in 2 days I first played this game. No offensive XD

#2: Osu!
However, my most favorite music game stands on my laptop.
I literally has to use a drawing tablet to play this game, since my mouse skill is terrible.

I'll post a video of me playing this game later.

#1: FIFA Online 3
This is my most favorite game on laptop. I login everyday possible for in-game bonus and play matches in weekends.
Here's a photo for people who don't know about this!
(It's Vietnamese so...)

2. What will you do if your favorite app was deleted?
Just download it again. But, if it's SIF then I would be really annoyed if I forget to save the transfer code.
And FIFA as well, since the game is really heavy. (~4-5GB, I think?)

3. Where is your background from?
I don't have a background on my phone, but I have one on my PC. And yes, it's my favorite game. Again.

4. Have you named your phone?
I just put the phone name as it's normal name: Nokia Lumia 525. Gosh, I really want to get rid of that phone.
My PC has a name, and it's HUANFIFAONLINE.

5. What percentage of apps you don't use but have for no reason?
Around 45-50%. Most of them are like Weather, Wallet, FM (Radio),... for my phone and some like Cortana (not even an app), Snagit, Sony Vegas, Photoshop (I am actually finding a person to teach me how to use those, 'cause I want to be a Youtuber) for my laptop.
