Nokia Lumia 920 sensitive screen might be a battery hog the way Windows Phone manages touch

Nokia Lumia 920 sensitive screen might be a battery hog the way Windows Phone manages touch
One of the most useful features in the Nokia Lumia 920, apart from the low-light camera, is the ability to operate the screen with something other than your bare fingers, which are not always bare when we get a call - on the ski lift, for example.

The guys over at JDB Pocketware are worried that this feature might cause unacceptable battery drain the way Windows Phone is structured right now. When you press the lock/power button or the dedicated camera key, and then touch on the screen, the standby sequence reboots each time, even if the proximity sensor tells it there is something very nearby.

Thus, if one of those keys gets inadvertently pressed while the Lumia 920 is in your pocket, the ultra-sensitive screen will keep getting touched, the standby sequence rebooted, and the phone will never be able to get into the frugal standby mode, thus draining the battery quickly.

We were also wondering about what happens if the power key gets pressed by accident in your pocket, and whether the phone might slide up the lock screen and start chaotically running apps or dialing numbers, but we are sure Nokia has given this some thought way before us, too. Still, we intend to test the bejeezus out of the Lumia 920's pocket behavior in our review.

The PocketShield makers even sent a letter to Nokia, detailing their concerns, asking for the Finns to look into this possibility, and set the proximity sensor not to power the screen if there is something nearby, if they haven't yet done so. 

Is the super-sensitive Lumia 920 screen taking from your sleep at night, or do you think Nokia has thought QAed this and taken measures way before all of us started to worry?

Really? I had to press the Lumia 900's camera button very hard to turn it on. Is it more sensitive on the Lumia 920 or something?

There is a thing called proximity sensor that can be used to make the phone not working if it is covered.

Add a password to the lock screen. Problem solved! and I dont think camera buttons on the phone are not very sensitive

Nokia will have to do something to fix this problem or else that could be a big problem on the part of the consumers when they're using their lumia 920 already

Think it should be quite obvious Nokia has thought of this looooong ago... what a massive non-issue, and this JDB site is most likely making fools of themselves.

ow comeon the issue is not even identified in the phone and people already getting panics it is someones imagination that may happen

If you read the source, it's a theory based on how WP behaves today and how Lumias behave today. Hopefully Nokia will change the related firmware (if allowed by WP8) - or - hopefully WP8 will change the behavior of the lockscreen.

Looks to me like someone is trying REAL HARD to engineer a controversy without ANY evidence and only pure conjecture. I suppose the next article will be on the 920 having an antennae coupling issue when you hold it...or misplacing cities and towns in its global navigation suite. Do you really think the Finns would release something without testing it in real world conditions? Do you think they forgot everything when it came to designing the 920? Go back to drinking your Koolaid.

That's why they're taking time to release the NL920!! Unlike the iPhone.

Are people so dumb even the author, common people. Its a known fact that all Nokia phones dont turn on unless the proximity and light sensor turns on. If the phone is in the pocket or in any bag even by press the on button the screen wont turn on. Why cant people with nokia lumia or any other phones test it by covering the proximity or even the light sensor and try to turn on the screen, it wont work. It did not work for mine. So i am sure this issue that the author or the other guy who wrote the letter has not researched before posting this.

I have 3 Lumia 800 and 1 Samsung Focus S. On ALL, if you press the power button they will turn on even if you cover the proximity sensor.

First we'll wait for Lumia 920 to hit the market. Then we'll try to draw conclusions. Btw, I stll think the Samsung Ativ S will be a better device, both in terms of battery life and quality.

battery life cant say but Quality forget it samy dont hold water on quality againt nokia not a bit

The solution to this issue is, screen must not power on if the proximity sensor detects proximity. Current version of Windows Phone does not take care of this. The big question is: will Windows Phone 8 take care of this?

I have not pressed any button on my Lumia 900 in my pocket once in the past 4 months. This is making something out of nothing. If the button could be hit by mistake in a pocket, that could happen to most phone out there in the market.

Until some reviewers get it in their hands all we can do is speculate. Lets give Nokia the benefit of the doubt, surely they have taken this into account and know what they are doing.

the sensor can save all that issue..when the screen is locked,,the sensor can act as lock if someone was calling,,and when u put ur phone onto ur ear,,the phone automaticlly off the lights so in that scenario, sensor can also be use to act as a lock too.because inside the pocket is a zero visibilty area.the same when we put the phone near our ears to answer calls.. i hope you got my point guys.. its not that big problem anyway.

Hey guys never mind this article. When Nokia announced the Lumia 920 they said that while the phone is in your pocket, the proximity sensor will not let the screen light up. This wil not be an issue, Nokia already thought about that.

All thumbs down from me, cause i don't like the OS and the Phone but love the Nokia 8800 series....

Good discovery, but no one has to teach Nokia, they would have done lots of research before bringing the technology to the market, so it won't be half-baked!

Talk about a crazy standard for Nokia- they are asked to defend against a speculative claim for a unreleased product by someone who has never even held it. Slow news day?

more easier solution although their is not such probem found yet lock the screen if press too long on and static response unlike in games which have motion all over the screen. it will work i know i make solutions like these in my projects :P
