Oo.. mi5 is better than iphone SE?

To close app(s) on iPhone SE:
1. Double press the home button to activate the App Switcher
2. Tap and hold on an app preview card and swipe up until it pushes off the top of the screen to close that specific app
3. Repeat the swipe up trick to quit other apps as desired, you can swipe left and right to navigate the app switcher as usual to quit apps not shown on the initial screen
4. Press the Home button once or tap on any app to exit the App Switcher

Pressing the home button once will bring you from the app you were running to the home screen. It will still run on the background

Well, even though the display itself is tough, it's not harmful to take precautions and assume it's fragile. I personally have a tempered glass screen protector on my iPhone SE, not only for the safety of the display behind it, but also to retain the feeling of swiping along a glass surface.

Not as smooth as Android? Can you mention more details about it? There was one time I had a Nexus 6P and my iPhone SE side by side to test their performance and I find the scrolling capability is almost identical to each other.

Spotlight Search is a tool to find almost anything on your iPhone. You can use it to search for anything on your device, including apps, music, movies, contacts and even information stored inside apps, such as a particular episode of a TV show. The search feature will also bring up apps on the App Store as well as popular websites.  It can search inside of your email and text messages, search your cloud services like iCloud Drive or Dropbox and look up entries on Wikipedia.

I usually use assistive touch then put on "multitasking" then swipe off everything. no need to press button twice.
Spotlight Search is useful for me to find apps i lost somewhere in the folders. ahaha.

anyone use spigen screen protector here?

Currently use the 1 come with ringke case, I'm very satisfied with it , won't get oily... But d scratch ...

Currently using a Spigen tempered glass screen protector. No scratches until now.

Nowadays, tempered glass can be had for as little as RM5. However do take care that many are also ciplak brand. Buy from reputable reseller such as mac city, machines etc. also do check for fitment. Some are all the way to the edge of the screen, whereas some are 1 or 2 mm from the edge. This reduction is to cater for those cases that grips the end of the glass. Do test fit for best result.

Found something intriguing while playing with iOS 10 beta 3. There's a feature which warns users when the Lightning port gets wet. Probably too late for some I guess

Actually, I kinda appreciate this feature. It does require some getting used to but once an expert, the home button is less used. Good thing that the button is floating.

Don't get what you mean bro? . AFAIK iPhone can be directly connected to any powerbank using the USB to lightning cable.

better features, reduce battery performance.
good trade off
