Hello fellow lenovo p2 owners i purchased this phone 2 days ago everything most things seem to be working fine apart from a couple of quirks. double tap to wake is hit n miss which is rather annoying but i can live with it in the hope future software will fix it. On another note i have noticed their is very faint red led light always on to the left of the speaker after i turn the screen off. Has anyone experienced this issue with the faint red led which when the screen is switched on goes off but whenever the screen is off i can see it light up just left of the speaker. I am concerned that this led might affect the battery usage in some way iff it is always on. should i take it back to the shop on account of this faint light always being on which appears much brighter in complete darkness. t
Thankyou all for reading.
That's the proximity sensor. Have you got any apps that use it?

Hi thanks for the reply the only app I think might be using it is Ac display but not sure.
OK fixed its a false alarm its definetly the app AC display which is using the sensor while screen off because i disabled the app and the red faint light vanished. the only other thing left is double tap to wake is fragile and needs about 10 taps to wake screen sometimes. Hopefully this is software related.
Why use double tap when you can touch sensor once to wake the screen?
not too sure but i prefer double tapping the middle of the screen rather than all the way up on a specific point where the sensor is.
Finger print is at bottom. Can also click it once with a non registered finger to bring lock screen up.
Kind of think dttw is redundant on a phone with front finger print sensor and physical home button.
To reduce the wear-and-tear like in iPhone home button...

As for me, I'll use the DTTW feature just to see the time and glance thru incoming notifications and if nothing important, the screen will turn off after 5 seconds... If we wake the screen, then, we have to turn off the screen "manually" (unless we set the display off timing to 5 seconds...or DTT-sleep is implemented...)
If we were to always "press" the home button, there is high change of "wear-and-tear" failure in the near future...
My iPhone 4 after 3 years, the home button failed due to "wear-and-tear" because too many double-click to get to the background apps...now the iPhone is running "virtual floating button"...LOL...
My current Note 5 home button seems to be very reliable which is now closed to 2 years ownership... But I'm not too confident at P2a42's front fingerprint scanner "durability"... Hence, I'll try to reduce the "clicking" actions as much as possible...
I wonder after warranty ended, how much is the repair cost for the fingerprint scanner... Should be less than 20% of the selling price...
Can see your point. I never own a phone 2 years lol so makes no difference to me. Don't think I have had a phone 12 months before either, just too addicted to em lol.

Hey i don't know if this deserves its own thread or not, but i think it'd be pretty cool if the proximity sensor on the Touch Pro 2 could be used like those on blackberries, that when you put the phone in your pocket or a case with the screen on the screen would automatically turn off then turn back on when you took it out. Don't know if this would be possible but it is a really cool concept. Thanks
blackberries turn on cause theres a little magnet in the cases that turn on and off the screen. i dont think any blackberries have a proximity sensor. the storm is the only one with a touch screen to accidentally hit but you have to click it to do anything, and if your pushing a bb hard enough into your face to make the screen click, you deserve the have it push random buttons.
oh ok, that kinda sucks, still be kinda cool if it could be done though
i was wondering if theres some way to change the sensitivity or distance of the proximity sensor, i notice when my wife was using the phone the screen would turn on and off randomly i guess because of the way she was holding it to her ear, then i started noticing through the corner of my eye that my phone was doing this as well, it must think i've pulled it away from my ear when it senses different cavities in my ear, i'd like to turn it up to an extra 1/2" or so when i do hold the phone to my ear i know for certain it stays off, and when i really do pull it away from my head the screen wakes up. has anyone found the settings for this yet? i'm running juicy rom and my wife has mightyrom

you could have it that way but you would need to disable the power off after x minutes. then all you would need to do is keep the proximity sensor enabled
Changescreen has an option under the advanced settings to suspend the phone when it's placed face down or in your pocket (as long as its put in your pocket upside down). It doesn't turn back on when you pick it up or take it out of your pocket though, you have to hit the suspend button for that. I'd reccomend checking it out.
Oh ya it also does screen rotation via the G-sensor.

I'm not sure if Changescreen actually uses the proximity sensor. It will shut off the screen even if you turn it upside down in the air. And I have found on numerous occasions that it still leaves the screen on in your pocket, which is too bad because it's handy to have.
Try PocketShield. It will automatically shut the screen off when put in your pocket or case. There is a free and paid version.

I'm with t0mmyr on this issue.
I too find that when having been on a call, my screen can end up with started apps, on the programs page, etc.
I too think that a 'tweak' on the proximity sensor will go a long way to fixing this issue. The trick is to find exactly what to tweak and this is where we need a little guru-like guidence.......!!!

theres a few interesting keys in hklm\software\htc\proximity. i wont mess with them. i wouldnt like the screen to turn on every time i pick my phone off a table or something.

Thx for the heads-up
I looked into them but with no result.
There must surely be a way to 'fiddle' with the range..?
Cheers
Jabberoo
i dont think there is a boost on range. i think the emitter intensity is fixed and would require hardware tinkering to make reflections on object brighter for the receiving sensor.

Actually I played with it a little and realized that it does in fact use the proximty sensor and g sensor. It just seems to bug up some times (or it just might be my device)
Not just yours mine does this as well. I make sure I don't move the phone away from my ear at all but if it is a long call it always seems that either the notification bar or the start button got pressed during the call. It is driving me nuts. I had a program written by someone on XDA for my Fuze that worked awesome called touch in-call screen tweak I want that functionality with the tilt 2

TouchLockPro has InCallTweak built in. See youtube video in the link. And recently also has added ZoomBar unlock. And it is *FREE*
Hey, everytime I am in a call, my ear taps the taskbar and it opens the notification window which covers my call screen. I have googled and searched this forum with no success.
Apart from TouchLockPro, was just curious as to if there is anything that addresses this issue?
Thanks in advance.
Do you have something (case?) blocking the proximity sensor? The screen should be turning off as soon as you put the phone to your ear.
Yes I do. I've just tested it out, that seems to be the problem. So is there any tweak to prevent this?
i know even with the screen turning off with the proxy censor i will find i am in the screen with the connections and battery info when i am done with a call... its kind of annoying and worrys me a bit i might accadently end the call when the screen is off.... also the flip over to make it a confrence phone is a 50/50 thing... this device is so glitchy
I randomly get this too, I think sometimes the sensor isn't used.. There are times I've noticed I can cover it up completely with my thumb and the screen doesn't go off, but other times it works just fine.

Tweak...some testing to see where the sensor is (somewhere along the top near the HTC logo) and an X-acto knife to the case?
same thing happens to me, most of the time somehow I turn on airplane mode and the call disconnects.. sigh
TouchLockPro has a feature which turns the screen off using the G-sensor, but it's not just for calls, if you have it horizontal it'll be on, and if vertical it suspends/screen turns off; this would be good if it was just for calls, especially for those that use a case.
I'm just starting to use TouchLockPro (http://forum.xda-developers.com/showthread.php?t=444215) and I have most of the locking features turned off - I just hit the power button if I want to lock it.
It does keep the screen locked during a call so I no longer hit the buttons. Plus - when it unlocks I'm right back, exactly, where I left off.
There's lots of options to tweak, I think there's something for just about everyone.
I LOVE unlocking with the zoom bar - first time I've used that thing on my phone

Awesome. Mind sharing what settings you have enabled, please?
Sure
Light Sensor, Stylus Sensor, GSensor, Nav Sensor, :
Nothing checked (all disabled)
Keyboard:
Use Slider, Suspend On Slider In, Slider Out Disables LockMode and EnableInputAtSuspend are all checked, everything else is un-checked (HTC Lock API, Double TouchPanel Lock and KeepAliveAlways are un-checked.
BattClock:
just some preferences set for appearance
Telephone API:
Everything is checked (except light)
Software:
Nothing set up
Other Settings:
AutolockOnPowerOn and UnlockOnACPower are checked, everything else is un-checked (added vibrates Lock/Unlock once - I like the extra notification)
~Eric
thanks! works like a charm now, is there any way to lock it if it is idle for like 30 secs or something without havin to hit the power button
There's a number of ways to lock it using the various sensors - you can try one of those and see what fits your habits / style best. You can also click on the BattClock icon to get the menu - the lock icon is right there. That's 2 steps though...

Using Desire for months and everything prefect except one thing. Sometimes I need to press the button on the screen after some system message which need to be heard first. When I put the screen on my ear then its off. I can use the headphone sometimes but not always. I believe its because of the sensing function but cant find the place to turn it off. Could anyone who can tell me how to keep screen on when answering the call? Thanks in advance.
The screen goes off due to the proximity sensor, but it should be back on again when you take the phone away from your ear.
This definitely works for me, though I can imagine that if you have your hand close to the proximity sensor it could cause problems.
Regards,
Dave
I tried again and notice that, sometimes the screen can come back but after long time waiting, but in most case it cant. I am not sure the position where the sensor located. I am using the zagg invisible shield screen cover and not sure if that caused the error of the sensor. Anyhow, is here a place to turn this face sensing function off?
PS, after I cleaned the screen cover then it seems get better response time to show the screen after move the phone away from my face. But still not rapidly as normal phone with keyboard and influence the using experience. So if there was a option to turn this face sensing feature off then it could be better.
I found this link where some one who had the same issue found it was related to their Zagg protector, but on the same thread there are others who have had no such problems.
The proximity sensor is in the top left of the screen, within the black border. circles - see here.

Dave
I was wondering if someone has noticed similar behavior on their G3. My G3 is 100% stock and is only a week old. Wherever I wake up my device, about 5 seconds after turning it the screen has a small flicker and the screen seems to auto adjust or calibrate. This only happens once every time I wake up the device. My auto-brightness is set to off and the screen is at 100% brightness. I did some tests and noticed that when I wake up the device with the top sensors covered (proximity, front camera etc), that the screen doesn't have this flick to it. Is there some sort of "outdoor" mode or something on these where the screen will self calibrate when it notices it's in a bright situation?
Please test on your devices and let me know if you see anything similar to this. I tried taking a video but it's so quick and subtle that the video doesn't show it.
mine does same. vzw. covered sensors, still brightness adjustment.
only just now noticed today, but could have been happening all along.
I think it has something do with the proximity sensor. If you cover the sensor with a note pad you cannot turn on the screen, prob a tap to wake feature so it doesn't turn on in your pocket. But if you lift the note pad just enough to turn the screen on and quickly cover it, mine does not flick. I have tried this many times and worked 100% of the times.
My friend who works for at said that his does the same as well as the demo. Must be a weird firmware issue. Hopefully its resolved in the next ota
How many times are you gonna make this thread?

I realized today my phone was facing inwards towards my leg and that it may be double tapping and turning on in my pants. Any way of stopping this, but also monitoring? I am just curious as I faced my phone outward it kept my battery lasting much longer today.

I had the same issue, but for me it turned out to be neither the back button nor double tap to wake. For me it was greenify, which does evil things when it doesn't have root: it turns on the screen, goes to the app info of an app it wants to hibernate, and "clicks" the "force stop" button, before going back and just leaving the screen on.
Of course this may not be the cause of your problem. You may not even have greenify installed. Have a useful way to debug the issue: install tasker (or something similar, maybe condi can do it too), and make a profile that makes your phone vibrate when the screen turns on. Make sure the vibration duration is distinguishable from notifications, 200 ms worked for me.
This way, you will know exactly when your phone turns on in your pocket. You will be able to reason about whether the back button was accidentally pressed or whether it's double tap to wake, or something else altogether, like greenify in my case.
Just a side note: it's unlikely to be double tap to wake, because double tap to wake will not turn your screen on when the proximity sensor detects that something is close. You can try that by holding your finger over the proximity sensor while trying to turn it on. Double tap to wake won't turn the screen on in the first place, and the screen will turn on and immediately off when using the power button.
So yeah, try the tasker/condi profile and see what your phone does right after it wakes. I saw mine force closing Facebook messenger like 7 times in less than an hour, and it stopped after I uninstalled greenify.

Ive noticed the screen on out of pocket but rarely. One new feature is the "slide down" quick peek while the display is off. This new feature may have new side effects.

That too doesn't work when the proximity sensor senses something is close. Try it by holding a finger over it while trying to pull down the thing with another finger.
