Sometimes when my phone rings I can't get it out of lock to answer the phone. When the caller hangs up only then I can answer. This is intermitant. I don't know what to do.
Running the stock ROM, and rooted with unrevoked.

What ROM are you running? Rooted or not rooted? These are things you should remember to post when you're having issues. Makes diagnostics much easier
All I have done was root it. I didn't install any rom or anything. I only rooted it to get the wifi tethering.
So screen turns on, but you are not able to press "answer" when a call is incoming?
Its telling you to hang up on stock rom and go custom. Plus you have better support specially being in this community.

I'm inclined to agree. Custom ROMs definitely go waaaaay above and beyond the stock one. I use a combination of MyBackup Root and Titanium Backup free for contacts/messages and apps, respectively. Once you go custom, you never go back
What I was trying to say is that the screen is locked when the phone rings and then when I go to answer the phone it will not unlock until the phone stops ringing. But like I said in the first post this doesn't happen all the time. I would say about 25% of the time it does this. Sooo... Thats what I was trying to say.
Are you using Google Voice?
Are you using Google Voice to direct your calls? I have 3 phones that GV directs my calls to, and I've noticed that sometimes that causes one or the other of the phones to ring "late". Sometimes the Inc, sometimes not. I don't notice an issue when someone calls my direct line to any of the phones.
I am wondering what you would get if you use an app like No Lock that disables the lock screen.
I started using it when I had a roms lock screen fighting with a launcher's lock screen. I would get stacked lock screens, but only sometimes.
Running without a lock screen is not for everyone, so think about how you use your phone before disabling this great security feature. For me, my phone never leaves my side, and I mean NEVER. And if a "friend" starts poking at my phone I start poking in their face or purse... They learn after awhile.

I'm not sure if I would like the no lock because I tend to put my phone in my pocket all the time and it would just turn on and pocket dial people. LoL

SetCPU?
Assuming screen is off when it cannot be unlocked - but...
Are you running SetCPU w/ a low screen off profile?
If not, maybe install SetCPU, and set a higher frequency in the screen off profile settings.
SetCPU is available in the market; it's also available as a free d/l for XDA members here on XDA.

Good call, I do remember when I was revving CPU way down with screen off. When it had been off for ~1-2 hours it'd be sluggish and take a bit for the CPU to rev back up. Never used it that long though because the Kernel I'm using now does this and using setCPU just chews up battery.

Well, there's something to try then - if the kernel is making the device slow to wake, use SetCPU to bump up the screen off profile and see if the issue persists.
Couple folk note just this issue in the kernel threads.
This is a known problem I struggle with myself. You may find that you can stroke up to deny the call but not unlock. It seems that this is some kind of grounding problem. Hearing that I tried setting the phone down and swiping while I wasn't touching it otherwise with some success. I've heard a quick cycle of the power button followed by an immediate swipe down can work. Some report pressing the screen firmly before swiping works. I usually just swipe up, call back and say "sorry about that, what's up?" After all, most people are used to drops and stuff because of Iphones.
I periodically goog "incredible can't answer" looking for the golden bullet.

The drag up/down (accept/deny call) is really idiotic when the phone is in a pocket, where you have to pull up the phone from the pocket when you get a call. Do anybody have any solution to this problem? are there any alternatives accepting/denying calls?
Yes, this is very frustrating for me also, haven't found a solution though!
Use Lockbot Pro from the market
You can choose from several types of locking screens, and modify them.
Word of advice: get the Pro version, it is much more stable then the free one
Thanks, I'll give it a try.
@fluor: I know a guy that use fluor as nickname...are you from norway by any chance?
Lockbot pro, is a bit lame, it only works intermittently!
I have only tried the free version, and have no intention of trying the paid one, just on the off chance that it may work correctly!!
Surely, a developer would wish to entice someone into paying for their app, by making a trial/free version that actually works!!
What's the bloody point, in making a free app that doesn't work properly, as if I would pay for this rubbish!
HTC should have designed an unlock screen that doesn't hang up your call, simply when you take it out of your pocket, I mean, is it really to much to ask, for a device that costs this much!
It's pretty basic stuff really.... I don't want an elephants ear on a bun, I just don't want to keep hanging up on people when I take my phone out of my bloody pocket!
i also hope for a free app. i see there are a lot when i search for lock, but not sure which actually work.
for the hang up problem, a workaround is to put the phone the other way when you insert it into the pocket, so it picks up instead of hanging up when you pull it up. however it's stupid.

You say Lockbot Pro is lame, but have only tried the free version??
I think you mean the developer is lame if he made an unstable free version?
All I can say is that it works perfectly for me, and I can only recommend it based on my own experience.
I had a few problems with the free version, yes...but I took the chance on the Pro version anyways...after all, what's $1.99 or whatever anyway.
And, now I have a lockscreen that works as I want it
also using lockbot pro now to get rid of the useless lock screen from sense.
but it doesnt solve this prob, as it doesnt lock on incoming calls
I have a workaround for you.
Put your desire in your pocket top first.
Then when you take it out of the pocket, if the screen is pressed, then "gesture" will be the opposite of what is needed to answer the call.
You will do a gesture up instead of down to answer the call. That is how I do it
Pattern unlock is useless too. You still get the slide to answer/reject screen before the pattern thingy comes up.
Is there a way we can solve this with a cooked rom? I'm trying to wait for the 2.2 rom to be ready, but this problem is annoying enough to flash now I think.

No pulling te screen up doesn't do anything, while pulling it up answers it.
I had a htc hero for about 8 months, always had it top down face towards leg.
Use the desire in the same way and never ever had a call in my pants.
I can't believe HTC have made such an elementary mistake.
I ended up buying a flip case for the phone. Solved the problem and protects the phone and screen as well.
Similar Problem
I have a very similar problem.. Because the vibration is so weak I often do not feel the phone go off in my pocket. Due to the warmth of my leg and moving around the phone continuously picks up by itself.
Does anyone else have this problem?
This is very annoying!!!
If I could only choose to answer calls by the hard button, it would solve it.
Has anybody (rooted) tried using the stock lock screen (the horizonal swipe as opposed to vertical), could this solve your problem?

Hello everyone,
I just bought my S3 last Sunday. Since then I have noticed several issues with it and I'm wondering if it's worth exchanging. They seem to be both software and hardware issues.
1. It's pretty laggy. For such a "groundbreaking" phone this is lagging much more than my old Sensation. It's rarely smooth switching between screens and going from lock screen to home screen is also laggy. Overall, it's not very smooth. Is this common on this device? Maybe I'm expecting too much.
2. The music player skips and repeats A LOT. Whenever a song is playing, it will constantly have gaps in the music. It will just stop playing for a brief second but then continue normally. It also will repeat parts of a song, such as saying some lyrics twice.
3. Whenever someone calls me, my voice sounds "distant" to them. If I call someone my voice sounds totally normal but when I receive the call I am either echoing or I sound like I'm holding my phone away from my face.
I guess my biggest problem is the lag. It really bothers me since it's supposed to be such an amazing and smooth phone. It takes several times longer to load apps and things than my old Sensation did, and I don't have many apps installed at all. Opening the app drawer is consistently laggy as well.
Are these common issues or do you guys think it would be worthwhile to exchange the phone? As of right now, I'm not very pleased with it.
Thanks for all your input, guys!
Edit: Also, whenever I hit the home button it takes several seconds to load it up. Is there a way to speed this up?
Also, I am not rooted yet. I always like to spend a few weeks with the stock setup before rooting.
Edit 2: Last thing, S Voice is a piece of **** on this. Literally. It takes FOREVER to load up and RARELY does what I say. Does this actually work for you guys or is S voice generally useless?
Not common at all. Exchange.

Smooth as butter.
Have you tried installing the latest OTA? It may help with some of your problems. For the home key lag, double press to open s voice, then go into settings and turn off double press home to open.
Sent from my SGH-T999 using xda app-developers app
1. Try this. Settings >Developer Options > Window animation scale ->change to 0.5x or off. Transition animation scale >animation is off
Also make sure Do not keep activities under developer options is unchecked. Check it first then uncheck it. This should solve the redraw issue on teh homescreen (at least it did for me)
2. Did not happen to me
3. Turn off noise reduction
For the distant sound issue open the dialer>call settings>additional settings>uncheck noise reduction. Even running unrooted the interface should be very smooth however.

that is yet another odd thing about my device. it claims I have the latest OTA, when I know I don't. Also, it says the music hub is still unavailable (even though I know several people who have it running)
I haven't actually used s-voice myself, but a lot of reviews said it wasn't very good.
Another thing you can try for the lag you mentioned is in Developer Options, change the Force GPU Rendering option.
Also try limiting background processes to 3 or 4. Though you shouldn't have to resort to this. If other options don't work id still take it back for exchange.

I just tried all the things you listed in number 1 and it is definitely faster, in a way. When I click the home button, the wallpaper pops up immediately. The apps however take significantly longer to load up and the app drawer still takes quite a while to load. I think I am stuck with a return. Thank you for all your help!

To speed up the home screen button:
Double tap home screen (bring up s-voice)
Tap menu softkey
Tap settings
Uncheck launch s-voice
You will need to do this with your new device as well.
And s-voice is generally useless, or as far as I've found.

Yea s-voice makes home button laggy. And have u tried to factory reset it?
Do a master reset without restoring back up. Sometimes this all that is necessary on any Rom. If that fails do a buyers remorse exchange.

I was just wondering if this happens to anyone else. So sometimes I go to unlock and the screen doesn't let me do anything, it happens not just when unlocking but when I'm using the phone too, it's really annoying when I'm trying to text someone back or try to answer a call. It doesn't happen all the time so I could live with it....but I'm wondering if anyone has a fix or has the same problem.
Also I have my phone rooted and g3 tweaksbox, and I turned off the knock in code..I don't know if any of these have factors.

It's not lag..I don't think unless it's a really long lag ?... I turn my screen on and off and it would still be frozen. Maybe after a few mins of turning the screen off and on again it will work...

i had this problem..it would lock up..freeze and i had to wait for a min or so to come back to life..a hard reset fixed it
Oh okay! That is good to know...I guess I'll be trying that soon
I have the same issue as well.
It's not that the screen "stopped" working. It works, except there's no update on the screen. As if the entire phone is frozen, but it's still giving me haptic feedbacks. Except, actions aren't being reflected on the UI; things like, tapping home navbar button, doesn't take me to the launcher, tapping up/back doesn't take me to the previous screen. I can lock/unlock the phone, but I'd return to the whatever page of the app that corresponds to the back/up command I previously made.
I think, the easiest way I can summarize this is that the OS stopped doing visual updates, while there's actually stuff going on despite that "stuck" screen.
Problem: Cannot turn on the screen by pressing the power button sometimes. The screen is black or very dim, I cannot tell. One can see nothing on the screen, and it doesn’t accept any touch input, either. The phone still rings if there’s an incoming call. If this happens, the following several presses (about 10 - 20) on the power button will probably lead to a reboot. The “screen auto-rotate” and the proximity sensor may fail after the reboot, but will recover after a manual reboot.
Frequency: Fewer with higher Rom version. About once per day for 4.3.
Other description:
The problem frequently happens when I just take the phone outside my house/office, and seldom happens when the phone just stays somewhere.
The problem seems to be irrelevant to the remaining battery capacity or the uptime, but it never happens when charging.
The problem seems to be irrelevant to the Apps installed.
The problem seldom happens in the first 3-4 days after flashing a Rom, but happens more and more frequently as time goes by. My guess is some cache is stuffed by some trash, which causes the problem. The phone may be fine as long as the trash can be cleaned up on a regular basis.
I manually reboot my phone at most every two days.
Solutions tried, but don’t work
Flashing official ROMs 4.0.4, 4.1.1, 4.1.2, 4.2.2 and 4.3 following the procedure “adb reboot bootloader; fastboot oem unlock; flash-all; fastboot oem lock”, without google wallet, not rooted.
Turning off the auto-brightness control, as suggested by some post on the Internet.

I think it's standing-by normally even through the screen is black (or very dim, I cannot tell), since it rings if there's an incoming call. I can see nothing from the screen, and I don't think the screen accepts any touch input, either.

I've also had this blank screen with calls still ring issue for as long as I can remember, nearly 2.5 yrs.
I've always suspected it's my ROM and so I'd try out another ROM'S, BUT no other ROM works like how I'd like, so I always come back to my ROM.
It doesn't happen every single day, but it does happen very often.
I've tried using apps that auto reboot daily, but eventually this blank screen issue will return.
Unfortunately I can't seem to find any solution, so I just put up with it, it's like the 1 only flaw with my ROM.
&
Not to be at all rude, but I'm really glad op has had this issue from testing other versions of Android, cause then at least I know I don't need to give up my great tablet mode ROM.
LOL
I think I've finally found a work around for this screen of death.
Using Exposed, download/install this module/extension:
Disable Proximity
http://repo.xposed.info/module/com.mrchandler.disableprox
It does exactly what it's name is and ever since then I've not once had to remove my GN battery to work again because the screen went completely dead.
NVM
Screen still goes dead.
Anyone find an actual fix to this?
isajoo,
I had pretty much the same problems with my Galaxy Nexus running CyanogenMod 11 M12.
It got better by doing the following :
Blowing dry air in the earpiece… though the proximity sensor is clearly beside it. Can't do any harm though, I guess.
Settings/Applications/All/menu/Reset applications preferences (or whatever that's called in english) : that seemed to do a lot of good to my phone ! However, it's a very unsatisfactory answer on a technical point of view, as I still don't know WHAT was precisely needed. It's a "magic wand" solution for which I can't give an explanation.
Not specifically related, but greatly helped my phone in the responsiveness area : Trimmer (fstrim) (https://play.google.com/store/apps/details?id=com.fifthelement.trimmer), an updated version of LagFix that you may already know
Hope that helped !

Not sure if this is how it's suppose to work or what.
I never really messed with the edge news, etc.. since i got phone, but today i played around with it. Once you initiate the edge display (with the clock) and start scrolling thru information. No matter what you do, the edge screen only stays lit for 6 seconds, even if you are in the process of scrolling thru. Is this how it's intended, what is the purpose, or is there a problem that would be causing this. Using Tmoible 925T with 5.11 (root and kernel) but i noticed this issue before going back to root.

Mine doesn't do that. I'm all stock. If I'm scrolling, it will stay on.

I think i found the problem.. I was using AcDisplay (Active Display App) - which does WHAT our phone should do automatically (adaptive display). When you pick up phone, it shows any messages, or calls or when you take out of pocket. (My S4 did this built in (running the s6 ROM)).
But i removed the app and it seems to be OK now, i think the app was messing with it.
Thanks for the responses everyone, that led me to believe it something specific to mine.
Now the only last problem i have is the samsung fitness tracker doesn't seem to count the steps all the time.. It seems like it's sleeping 80% of the time!
