Phone freezes on the unlock screen/ slide button

Hi everyone, I just purchased 2 HTC HD2 phones from T-mobile 5 days ago and every thing was fine until 2 days ago. The phone that is mine started to freeze on the unlock screen / slide button, will not unlock all the time, sometimes it does sometime it doesn't. I have to remove the battery and reset to unlock. Both phones came with the same firmware version 2.13.531.1 but only my phone freezes and not my wifes. I read in the T-Mobile forums that, the latest update would fix my issue. So I update my firmware to the latest version (actually reinstalled latest version as it was already installed on phone, to see if that would fix issue) 2.13.531.1, to fix unlocking issues in the lock screen. But after updating several times and trying almost every thing I have read about in this forum and HTC's forum, like disabling sensing and cleaning the RAM removing locations from weather app and permanently deleting all text messages and emails, and disable autolock with cab file, Nothing has worked. I have 2 HTC HD2 but only 1 freezes. They both have the same firmware version 2.13.531.1. The only work around I have found is to deactivate automatic shut down in the settings menu to keep the phone from locking automatically sense it only freeze at the unlock screen/slide button.How ever this drains my battery alot faster because the screen only dims but never shuts off and its not a real fix to the issue. If anyone knows of a real fix please post here will I check again for any knew posts......................Thank you .
It might just be a defective phone.
I for one started on the (i believe its 2.10) firmware & then upgrade to the 2.13....HATED IT. They 2.13 which was supposed to "fix" certain bugs seemed to make mines worst so i reinstalled the original 2.10.
Im not sure if they do handset trade where you are, you could call the store and find out, if not, you could always downgrade the software to see if it works, or just flash a custom ROM....
Or wait on hole for a TMO rep and see if they can just send you a replacement (once you got through a bunch of troubleshooting that most likely wont work).
Good LUCK!
mine also freezes on the lock screen, is there a way to deactivate the lock screen during standby?

anoying white screen

Hi guys, this is my first post here and I hope someone can help me please!!
I got my phone 5 weeks no problem till last night,
basically when I am in screen lock state and then go unlock, I keep getting this anoying WHITE screen which coveres the whole screen and only on the top in narrow blue band it say "wiedges setting" to get out of this, I have to press the return button (on the right ) and it goes away , this happens everytime I go to lock position (after it stays in that position for 5 minutes or more),
Also I noticed even DURING my call after about 5-6 minutes through out the call this white screen appears and it ALWAYS goes away as soon as I press the return button.!!
so please tell me how to get ride of this?
if not, how to reset the phone without losing my apps and data? if I do factory reset is my apps will stay in andriod market, or do they also get deleted?
my phone IS NOT rooted phone.
what can I do, this is really killing me, as its everytimes into my face.
Please help me...
thanks so much
ps. is there any way that I can reset the phone to previously saved version! (3 days ago lets say),?
Sounds to me like an app causing this, as it seems it wants you to alter some settings.
Can you think of any apps you have installed since it started happening? It is usually always the fault of a dodgy app when you have issues.
I am not sure you can restore the phone back 3 days if you havent already done a backup.
Restoring your phone won't necessarily help as you will probably end up re installing the bad app once you are done.
I would try taking off some apps that you installed recently or anything you think might affect the screen.
Good luck and i'm sure someone else will be able to help
Biff.
edit: if it only started last night, is there anything you've installed just before it happened?

[Q] Random unresponsive home and lock button

Hi,
I am having some serious trouble with my note 3.
The basics of the problem are that the lock button seems to lock the screen but once pressed again it shows whatever was on the screen before, not the lock screen!? Holding the lock button does not come up with the turn off/reset options.
Another odd thing that happens along with this is that any application that is opened or closed the screen flashes black before opening up.
Along with this I have found that the alot of the native apps, including phone, contacts and most annoyingly, CLOCK, crash also. Making me late for work and rendering the phone useless unless I do a battery pull.
I will note that the most odd thing is that I contacted our business contract guy who who i expected to tell me to do a soft reset, told me that the supplier would swap out the phone?! That was last week and the new handset is showing early signs of the same thing.
Neither phones are rooted and I have not installed any unknown sources on the new handset to be sure it wasnt an outside source?!
Any help would be appreciated.

Factory Reset

if not work take to service cause it should be hardware problem.

But why would the problem occur on two separate brand new devices?
because you have the same app on both phones :highfive:

Well some of my apps install straight onto the phone.
Do you think I should remove as many as possible and try then?
Same exact issue here

I am having this same exact issue. First happened when I installed a SanDisk Ultra CLASS 10. I thought the card was causing me compatibility issues so I returned it to amazon. This was just a few days ago. The only thing that worked to fix this issue was to remove the battery.
On the way to work today I suddenly couldn't play any music downloaded from Google music to my device. However, I could stream music that was not downloaded to my device. I also couldn't view any pictures in my picture gallery. I tried rebooting the phone and guess what -- I got the same exact issue as the original post above.
I wasn't going to mess with my phone while driving so I made up my mind that I was going to return it to verizon tomorrow. About an hour into work I picked up my phone and it gave me the onscreen instructions to swipe up to get flip board -- same instructions it gives you after a reboot. I then tried playing the same music that wouldn't play before and it played. I tried viewing pictures in the gallery that were inviewable before and they were now viewable.
I'd like to know what is going on too. I can't just give up to the fact that my phone doesn't want to work at certain times of the day so I just have to give it an hour.

The best thing would be to remove all non-factory apps. But yes, start by removing as many of them as possible.
(If that doesn't work, do a factory reset and cache wipe through the recovery menu, and don't restore a single app. (I'm not talking abouy the bloatware, we all have those.))
If there are no problems at that point, add back your apps one by one. (no restoring anything, make sure they are clean installs.)
Eventually you should run into whatever app is causing the issue.

I reset the system to factory settings and started arranging only the installed apps and widgets and I got the same lock screen issues.
This time the phone wouldn't go to the lock screen but it would give me the option to restart or shut down. I set it aside again and when I picked it up a few later it showed me the home screen wwith instructions on how to access flipboard -- as if it was reset! I have a warranty on mine so I'm gonna return it to verizon tomorrow or friday.

screen constantly switching between lockscreen and stock homescreen

Okay, so yesterday I was out with friends and my battery was low.When I had to use my phone, shortly after the battery died.I came home, started charging it and when it had about 20% i turned it on.Ever since that, my phone is constantly switchung between my lockscreen and stock homescreen, with me not being able to do anything(go to the settings or something like that).So I hard reset the phone and when it booted up and I was going through the basics, one message popped up every few seconds: "The UI has stopped working." So it was difficult to go through all that stuff, but I made it only to see the problem is still the same.I also tried to take it apart and blow the dust off the MB hoping it would work, but unsuccesfully.I also have to mention the screen is cracked very bad and you can see inside the phone down where the LG logo is, but the phone was working absolutely fine in that state for over a year.Any help? :crying:
I'm guessing that you didn't have a lot of storage left on your phone, right ? A similar thing once happened to me, rebooted while storage was completely full. Refused to work until I reflashed it.

Fingerprint hardware not available and screen locks itself immediately!

Hi everyone!
I have a OP 2 for more than one and a half years now and never had any issues with it(stayed stock...) until recently. I didnt update the phone to the latest version and was putting it off, and today in the afternoon when I tried to unlock my phone it said the 'Fingerprint hardware is not available' and after unlocking the phone with the pattern, it IMMEDIATELY LOCKS ITSELF BACK !!! after split second it just locks the screen while everything is working like connection, wifi, messages, notifications, etc. but due to this I cannot access anything on the phone, can't go to settings and switch to onscreen nav bar buttons, can't force stop/wipe cache the com.fingerprints.serviceext either, tried restarting it several times, downloaded the update but can't even install it because the phone just locks!:crying: I have no idea what would fix it and I am avoiding a full reset and wipe on the phone(also based on all i have read, dont think it would fix it anyways)
If anyone knows whats the problem or has dealt with it or knows someone who has, please help me out here on how to fix this and what to do. I did not root it or flash custom ROM's on it yet and never had a flip cover or any sort of case so literally don't know why it happened.
Thanks in advance,
Max
Hi
I had the exact same issue with mine, I was on LineageOS and could access the logs so I was able to determine it was an hardware failure.
Went to a repair shop to replace the home button, and Bam it worked again.
If you didn't flash a custom ROM it is likely an hardware issue just like I had.
