Just for discussion purposes.
I don't think the sensor is for convenience purposes. Why want to spend the money there, when they can just put a blank button there? No matter how you press, it will unlock the screen for you.
This is convenience.
Due to a dirty thumb, you cannot get it to unlock the screen, this is not convenient at all.
Because of security reason, you have to produce the exact image to unlock the screen.
Security got many levels. This is only one of it. The other is the 6 digits pin.
I have seen one company changed the 6 digits pin to 8 digits pin and every month has to change pin.

What you can do now is don't on it for few days. Let it complete dry, probably it will alive back.
Ask your friend buy back your phone, he/she need to responsible to this. If he/she refuse to it, remember such "friend" is not a true friend.

Exactly, I am shock when I seen the comment back. To them that is feature, what to do. Definitely not for me.

My company also need to change password every month la, and the password must combine with alphanumeric and symbol.
Re-used password is not allowed.

For me this is design flaw, not the reason strengthen the security. It had nothing to do with it.

I consider this very good security.
Fingerprint scan is also for security since banks are using it to verify your identity.

Fingerprint off course is security but how effective it can recognize is another story.

Thank you for this statement.

U have some good points but still I feel that touch id is more for convenient purpose rather than security.
For me, if it's really for security purpose it would be able to detect ur fingerprint no matter it's dry or wet. I don't understand the technical part of how a fingerprint is being registered or how distorted it gets if the finger is wet. But I compare my 7+ to an old iPhone 6 and the iPhone 6 recognize my sweaty fingers more accurate than my 7 plus. The 6 might not recognize it as fast but at least it's much much more accurate than my 7+.

This is my point of view.
For convenience, why want to scan the thumb/finger? Why not disabled the scanner? It is more convenient to press the home button with anything, pen or pencil.
To me, it is for security because like pin, you set your pin when you set up the phone. When you want to access the phone, you must key in the correct pin that matches the one you initially set.
Same for fingerprint scan. When you set to use the fingerprint scan, you have to scan your finger/thumb.
When you want to access the phone, you have to scan your finger/thumb. If it matches the one that you initially scanned, you are allowed to access.
Now, if your finger is dirty, lets say got ink on your finger, when you scan, the phone is trying to match it but fails to do so because there is a dot now but the original one got no dot. Since it is not the same, the phone denied access.
Maybe when you set up the fingerprint feature, you scanned all your 10 fingers, now the phone has to try and match all the prints in the database. At this instance, you might say that the phone fingerprint scanner is not working, but in fact it is trying to find the correct match in the database.
Now, the iPhone 7 home button is different from iPhone 6. Maybe because of the difference, both models behave differently.

Aiyo why all the fuss? Don't like then disable the feature lor. Apple didn't force it in ur throat. Better yet, then change android lor.
Example last time Sammy come out with eye scanning auto scroll up and down page feature. Use until I fed up. In the end just disable the useless feature and continue using the phone.

Haters gonna hate. But will continue using. Speechless.

Like above forumer say, just scan all 10 fingers. One will surely unlock it 😂

ya u have a good point there. Perhaps it's a mixture of both security and convenience. Like I want security so i set up passcode, but i don't want to always type the 4 numbers so i use fingerprint so it's more convenient.
Sadly u can't add all 10 fingers (if can i sure will lol) ya my guess was that the home button is different to previous models, so the mechanism oso different, hence the fingerprint doesn't work as well as previous models.

this is forum bro, which is used to post personal opinions. what's the fuss about that? Nobody is hating on anything, don't have to get so protective lol.
If can add 10 fingers I will sure add, now I even add 2 fingerprint for my right thumb

After going around, some sense is finally seen. Kudos to you for your patience and persistence.

I don't even bother to reply that person. HaHa!

I always add 4 fingerprint for convenient. Haha! each hand 2 thumbs because when holding is easier to use main thumb but if put on desk, 2nd finger is much easier.

Off course I know fingerprint purpose is security but not means a lousy sensor equal to more secure and better sensor equal to less secure.

Secure also not means shall be less convenient on usage.

Did anyone of you ever experienced some heat/warm behind the back of iPhone while using camera (for iPhone 7+).

I found out that when i took few pictures (5-10 shots), the body became warm a bit. i've never experienced this on my iP6+ before. just wondering, is it normal?

Morning all,

For those having reliability issues with the Finger Print system, at what percentage (%) of the time would the FP access fail on you and had to use the 4 pin password to enter home screen?

I myself assigned 4 fingers, r.thump & r.index and l.thumb & l.index and come to think back had only about 2 occasions that it failed to register and both of them was when i had it on a phone stand on the dashboard holder. I deduced that it failed due to the shaking of the unit. Thanks.

Anyone know where can i test BeatsX? Would like to try it.

i had 2 fingers registered and recently it started to fail on me a lot of times. previously it will work even with wet fingers, but now its starting to fail on me quite a lot of times, while holding it steadily.

i would say 50%.

i think the more sensible thing to do is straight ask for a new phone from your friend lor.

mine has been through ice bucket, shower and swimming pool, still fine

i read somewhere before register the same finger twice will improve the sensitivity of the home button. works well for me
