Does this happen randomly or when accessing particular application on your phone? Pressing the down volume and power keys together until the phone vibrates and starts up is what I'd suggest. Is this the reset you did?

Freezing may also occur when you are multitasking or accessing multiple applications. Make sure that connections you are not using are disabled (NFC, WiFi, Bluetooth, etc).

When did you purchase the phone? If the issues persists and is getting worse, it's best to bring it back to the retailer for replacement as soon as possible. Do not forget to bring the proof of purchase.

bought lumia 720 a few weeks back.. the lock screen freezes constantly does nt even restart with volume down plus power key.. please help happening since second day.. phone is not used much other than calls and fb on wifi

Hello RSM12,

You have to explain the situation a bit more like i did. What were you doing when the freeze happened? what freezes and what you seen on the screen. 

Do you know to press hard reset by Volume Down Key + Lock Key pressed together for about 10 seconds? Did you do that ?  Why you need to remove sim card? 

I think my problem and yours are different. Please give a clear picture. 

@ Moderator ; Could you please help with my explanation that i gave in detail? 

Regards,

Binny.

Hello Musica,

Thanks for the Prompt Reply.

I'll explain in neat how this happened.

OCCURENCE 1:  The first day

******************

1. I purchased my mobile on April 20'th, which is just 2 days after it was released to stores in India.
2. That day night i just tried Wifi, contacts, people hub etc and was going well till then.
3. I wanted to change brightness settings so, i was checking auto, low, high etc. I set it to Low, Then Locked the phone using the button on the side. After a minute i wanted to open up the Camera by pressing on the shutter button (when the phone is still in the locked condition). I did not see any camera opening up. I then tried to Unlock the screen and it dint. I tried almost everything, volume  up, down etc.. nothing happened. 

I tried to connect the USB cable to the Phone and access it through laptop, and gracefully i saw that the folders appearing on the browser. Hence i confirmed that the phone had power supply and some part of it is still running.

Please note that this just happened as i said 1) change screen brightness - changed few times between options, and finally settled down to Low 2) Locked the screen 3) Tried to Open camera by press and hold Shutter button of camera.  -> Thats it after that i was not able to see anything on the screen.. The screen was clear Black and even the windows and other two icons below did not glow for any operation i did.. 

I had to reset the phone to get something on the display back again.

And clearly to say that - This Problem is not re-producible in the same way again.

OCCURENCE 2:  4-5 days later(This time luckily i dint want to restart, plase read below)

******************

1. I was in the "settings" menu searching something on the settings. I think i set the wifi on and came back to the settings main view.
2. assuming wifi was on, i wanted to go back and open browser, so i press the back key and nothing happened. Still the settings menu was showing up. 
3. So i thought it was stuck and tried to click something on the settings. Neither a touch nor any sort of selection was not accepted. instead the screen Freezed in the same Settings menu.
4. NOW, i just randomly tried few moves on the screen just to try wake it up. And i found a glimpse of LOCK SCREEN coming down from the top (i think) in a slow motion (unusual than the normal appearance). 
5. Now i have the lock screen infront of me, and i slowly slide it up as usual. The phone was unlocked and then i had the settings menu there which now resumed working.

This was strange to me as a Software Programmer to realize why the lock screen appeared on the fist place and why was the settings menu first was not responding.

Please note that this time i dint have to restart the phone luckily.

OCCURENCE 3:  Seven days later after the purchase

******************

1. Installed photosyth. Took a photosynth capture

http://photosynth.net/view.aspx?cid=0b887c2e-aa42-4491-9c60-4d0fd43e6356

2. If you see this photosynth image, in some place you will note a Green Color like coating sort of a paint on just the left of the church View. It sort of covers the leaves like a thin green Film. 
3. Please note - that was the last frame i shot in the Photosynth lens before i continued to stitch. 
4. Stitching complete and the image was just as you see in the above photosynth Link. 
5. After this i wanted to use camera normally, and when i do so, i see everything as "that green color" which appears in the photosynth image that i mentioned.  i closed Camera and opened it again from the start menu, and NO... Still it was the same green. I wasnt able to see any objects that i aim. Fully green.
6. Left with no options, but in a hurry to take a picture, i had to restart the device..

These are the just three occurences that i had during these 10 days after purchase. 

I tried hard later on to test the device by trying the same things, but never happened. I am particularyly bothered ONLY about the issue 1 & 2. Third issue is definely because of PhotoSynth causing something. May be it didnt flush anything out of the camera buffer memory.. or dont know what exactly made that green there in the image and later on the full viewfinder... :( 

The device otherwise works exceptionally well and hence i dint want to immediatly go and check with Nokia Care, because the problem was not perfectly re-producible. 

==> What do you think? I certainly feel that it could be a software issue with 1 & 2? 

1. Would you be interested in some logs in case the issue occurs again? 
2. If the issue occurs again, and i just take the phone immediately to Nokia Care, should i suggest something to them on Your behalf so that they dont try to diagnose something wrong? Because if they reset it, reproducing the issue is hard. 
3. Do you think i would need to ask Nokia Care to run any diagnostic tests for "this specific  issue"? Do you have such a test available & instructed to all Nokia Care Engineers?

Please suggest.  Rest all things in the phone are fine and its absolutely smooth. Even if i exchange, i dont have guarantee / rather convinced that this issue will popup again in the new phone (if at all). So i want to know the root cause before i exchange so that it does not appear again in the new phone.

Thanks,

Binny.
