Back light delay when unlocking phone - HTC Sensation

Hello,
I recently got an insurance replacement of my phone, and this one seems to have an odd issue and I'm not sure if its software or hardware. Basically, sometimes, (frequently) when I go to unlock the phone, I will swipe my finger to unlock and feel the haptic feedback and such, and if its bright I can see the LCD on, but the back light will take an extra 2 or 3 seconds to actually turn on. There's also a bright area in the screen, not too major, but noticeable when reading text on a white screen. Should I contact T-Mobile for a replacement? My phone is still in the 1 year warranty. Could this be a software thing? I'm running virtuous Inquisition 4.0.2. I don't remember this happening on my phone prior to the insurance replacement. My old display was the acer, and this one is the sharp, if that makes any difference.

Bump? Should I warranty this?

I think you should try to warranty it.
I'm also running Virtuous 4.0.2 and never had similar issue.
But before that try to test other ROMs - do they have similar issues?

I tthink the bright spot may have actually been caused by my phone overheating overnight a few weeks ago. Was at like 170f before I woke up and turned it off. The bright spot is right near the sim card slot which is what was hottest, where the processor must be. I think I'll just warranty it, T-Mobile tends to be pretty easy going with warranty returns.

I called tmobile, told them my phone overheated for no reason overnight (even though it was probably my fault) and that now there's a screen defect, they didn't even put up a fight, took like 5 minutes to get a replacement out of them. So easy. Should I unroot the phone and go back to s-on and all of that stuff? Do they check for that? Or do they just check for water damage and cracked screens, etc.? I'd hate for them to claim it was out of the warranty terms. I just don't want to brick my phone returning to s-on, which I know is a bigger risk than when going s-off.

WTF is wrong with this phone?

Hey guys.. So I've had my inspire for about 2 or 3 months now, and this thing is driving me apeshhh. Here is why...
For a few weeks now, the phone would randomly restart in the middle of doing something, always random. Sometimes while writing a msg in the stock facebook app. Sometimes when browsing market, sometimes when browsing using the web browser. Today I wanted to download Astro to see if the music I put on the phone went to external or internal SD. As soon as the download finished, the phone restarted. After it booted back up I looked through apps, and it never installed. I went back to market and searched it, pulled it up, and it shows installing.... let it sit for 5 minutes... nothing. Restarted, same thing. Pulled the battery... same thing... I can't cancel it, or try again. It will now no longer install anything else.
I figured maybe it needs to download something that it just doesn't have the network speed to use, and trying turning on wifi. IT WONT EVEN TURN ON. Under the settings menu to turn it on, it says error. When i tap on it, the error msg just goes off then comes back right away.
Anybody else experience this? I really wish SOMEBODY would come out with a decent f**king phone on the AT&T network.... I guess I can now add HTC to the list of people that can't build a decent phone. Just below Samsung... (What a POS line of phones they have released).
Anyway, phone is stock, not rooted, nothing turned off, completely stock.
How does the warrenty work now? I bought the phone outright, cash, $500... for this....
Thanks for any help.
Could be your phone mate. I've had this phone maybe about three months and haven't experienced those issues. Just might be a lemon you have. Where did you purchase the phone?

I bought the phone at an authorized AT&T retailer store. The kind you find in common shopping strips.
Try to see if they will give you a replacement

Back up your stuff and factory reset. If that doesn't work then either Root it and try a different ROM or get a replacement phone.
You might want to look at the thread in here about random shutdowns. It looks like the batteries on these phones can be the culprit. My phone randomly shutdown, sometimes restarted. I thought it was a ROM I had loaded at first. The problem got progressively worse no matter what ROM I used. It would do it maybe once a day & then within less than 3 weeks I have to keep it plugged in all the time. It happened when I opened a power-intensive app like navigation or a game. The battery is covered under warranty.
This issue seems to be rather uncommon, but it does exist.
Nothing compared to what Captivate owners went through.
Lemons do happen, but as suggested, I'd try another battery first. If that doesn't solve the problem, there shouldn't be any issue with getting a warranty replacement.
And that warranty replacement will, with near certainty, be a good one. Again, unlike the Captivate.
I've had mine for about 3 months with none of these issues. HTC phones for me have been great. Even their customer service and support if their products. And I have had Samsung,motorolla, and LG none at the same level of build quality. If you continue having problems get in touch with the HTC support they will help if not let u know if you can get a replacement.

I am a former captivate owner. That phone was so bad that it destroyed it's own internal memory. Every app continously force close, every process, upon startup one day. Restored a backup, got nothing, reflashed, got nothing, mounted it and formated it then ran a memory checking utility on my computer with it, and it showed like 46% of the sectors being bad, after then 2nd test somewhere in the high 50s. I promtly punched in the screen and folded the phone in half, and tore it into 2 pieces... So i think that may be why I'm relatively patient with this phone.. (that was also my 3rd captivate replacement). (Debating using a picture of the phone as-is in a DIY to fixing captivates and post it in that forum... get all your frustration out and buy a new phone.. ha ha.)
I will call HTC and see talk to a rep, maybe they know more about the problem and will be able to determine whether the phone or the battery is at fault.
Also, factory reset did not fix the wifi problem. Instead of immediately going back to error under it's status, and spent about 10 seconds trying to connect, then came up with error. This leads me to believe it's hardware related.
I will most likely push for a replacement phone then. I do have a concern with that though... My phone has never gotten wet, and only has a small indication of falling out of my pocket while sitting in a stadium chair (maybe a 12 inch drop onto concrete). Will this void my warrenty? The scar left behind is hardly noticeable, but if they looked for it, it will be seen. Another thing is, when I pull my battery cover off, there are 2 screws along the side, one is covered by a sticker that reads VOID, black sticker with white text. Is that some kind of indicator of water damage? I'm more familiar with white stickers turning red or pink from water damage... and as said, this phones never been wet.
Thanks again for the help.
At&t is usually good about replacing defective phones and will be faster than dealing with htc. You obviously have experience with at&t warranty having owned a captivate.

Those stickers are intact right? As long as their intact and not "punched in," which would indicate a screwdriver has penetrated in order to get the phone open, you should be good, as far as that's concerned.
Uhh well bad luck for you... I dont think this is a common problem...
Im guessing the iphone is on top of your list xD

Sensation needs reseating into back cover occasionally

I've had my sensation for a little over a month now, and recently I've been having a bit of a problem.
A couple times a week, I'll pick up my sensation from sitting on the desk and use it like normal, but every time I touch/tap on the left side of the screen, the phone has a little give as the screen pushes into the battery cover and I hear a light click. this usually freaks me out, but I'll continue to use the phone like normal (since there's not much else I can do). after a minute of typing and checking email, the screen finishes reseating into the cover, and the phone feels perfectly solid again.
has anyone else had this problem? It's hard to recreate, the first time it happened was while rooting (having usb connected) and it took almost 5 minutes for it to reseat. Now it usually only takes a few touches to reseat, and the best way I have to recreate it is to leave it out in a cool room overnight without charging.
Should I try a warranty repair on this? I doubt HTC will even be able to recreate the problem. I ready don't want to have to deal with it like this, and it has the dust under screen issue as well, so I might be able to push it until I get a replacement. Any advice would be appreciated.

Warranty!
Your metal parts are expanding when its getting hot never heard of this!
Dust under the screen is a point where you will get a new phone 100%
Yeah warranty for sure but if I were you I would leave out the screen coming apart and only note the dust under the scree. I would leave out the screen issue only because they may use that as a reasonm to deny the claim. Not saying this is what happened buty I know working at T-Mobile tey look for any reason not to process a warranty and thy could say that that is physical damage caused by the user. So I would recommend just pushing it together telling them about the dust and calling it a night

Sensation screen unresponsive for short time after turning on

I have just replaced my digitizer (was dust under the screen and also a scratch on the digitizer itself, along with the fact I damaged it removing the sticky tape) and the whole screen is almost completely unresponsive. Brand new, but wont work fully until I touch the screen for a bit or give it time to sit after activating the lockscreen.
Once it is through it's "warmup" the screen works flawlessly. It just acts like a slug before that... Also rendering the quick launch lock screen completely worthless. Anyone have any ideas what could be the culprit?

I too replaced a broken screen on my sensation, and i am experiencing the exact same problem as you. Only for me it's only the lower left part of the screen that 'takes time to warm up'.
Did you find any solution?
Not yet. I have another digitizer on order, and fingers are crossed. If not, ill be biting the bullet and waiting for the nexus prime. I have this feeling that it is something other than the digitizer which is extremely sensitive. If people are claiming responsiveness issues after a week or two of use, and while on their sixth or seventh sensation... It sounds like something is slowly deteriorating or building up.
Sent from my HTC Sensation 4G using xda premium
I don't think it's the digitizer either, probably something else ont he phone. However i don't think it is the same problem as everybody else is having, since they experience their screen being unresponsive in general rather than just after turning on.
I am though going to try some of the fixes suggested, i.e. improve the grounding by placing some aluminum foil under the cover and see if it helps.
What does "turning on" mean? Cold boot up? If so, then the CPU on the phone will be busy doing stuff. If you mean waking up from sleep, then that's another problem.
for me it's both cases, both when booting the phone and just when turning the screen back on. What's strange is that it is only the lower part of the screen that's frozen :-S after 10-20 seconds it suddenly springs back to life just as nothing had happened and works flawlessly until i turn the screen of. Then i see the exact same problem again.
I also noticed now that the screen also freezes after calling somebody and when you hang up :-0 I really don't know what is wrong with the phone!
If the phone is unsecured (never sleeps) it will work flawlessly. As soon as I click the top button to secure the screen, or take a phone call, once I try to unlock/ use the screen again... The problem comes back. The left side of the screen is the most responsive, usually moving my finger around for about five or ten seconds will restore full sensitvity. I received a new digitizer in the mail, just waiting on tape. Interesting note; they are different digitizers. The original was HTC/ tmobile brand while the replacement is simply HTC. The ribbon cable also reads different. My original: pyd v1.0, sw-10 94v-0, e3082521117. The new one reads: pyd v1.0, e21954-1, ruICACichia, 94v-0 1112. The current digitizer replacement is also a standard HTC label... I wonder if it is because it isn't a specific model replacement.

Alright so i tried doing all the fixes related to the grounding issue, and i didn't affect anything at all.
I'm going back to the repair shop today (have a three months warranty) to tell them to have a look at it again and see if they can fix the issue. Maybe they have a spare digitizer they could try instead of my current one. I will let you know if anything helps!
Sounds good. I am betting its either an incorrect digitizer for the model of phone (us/eu/whatever) improper mounting or damage, or just planetary alignment or something equally stupid. I'm really hoping someone figures out this problem... It is frustrating to spend more time figuring out how to fix a phone than you actually do using it.

True, had i known from the start i would probably just have bought a new phone, rather than spend on the money on getting the screen replaced :-S
Well, I replaced the digitizer for a second time. Seems to be the same thing so far. Different initial responsiveness spot (looks like the right side might be more sensitive now) but I didn't have high hopes. I wonder what it could be...
Sent from my HTC Sensation 4G using xda premium
So i went back to the repair shop and got it fixed. I guess they weren't in the mood for scientific inquiry, because they simply disassembled the phone and installed a new digitizer. After that everything is working fine, altough i will never know if it was the digitizer itself or some faulty wiring somewhere :-S
Worked for me
I have had exactly the same problem you all have experienced. The first digitizer I ordered from a company on e-bay gave me huge problems at the unlock screen. Bought a new one from skalshop and it works perfectly. I even tried it without tape to make sure it worked before I glued the thing together and it worked perfect.

[Q] Screen lag after changing digitizer

I dropped my Sensation while on vacation in Key West. I arrived home and bought an HTC OEM digitizer. It came, I put it in and now when I unlock the phone the screen lags for 5-10 seconds and then it is perfectly normal. It will lag that long also if a call comes in. Hard to answer it sometimes. But then it is fine until the next time I shut off the screen and put it back on. If I leave my display on all the time it is fine. Only coming back from sleep. I am in IT, A+, Net+, Sec+ and MCSA certified. So no problem with changing it, it went fine. Any idea what it could be?
You sure it's OEM. I think you bought ebay stuff that is from china. You get what you pay for. I would try to flash another ROM just to be sure.
Also download z-devicetest from the market and check out the screen specs.

I replaced my digitizer and I currently get incredibly annoying unresponsiveness every time I unlock the screen. Very frustrating. Also, it seems to only have zero response on the right side. The left side (with the phone quick launch) will move after fidgeting with it for a second, and then the rest of the screen will follow suit.

sounds like the EXACT problem i had with an TMOUS 1024mb HD2, replaced digi with the one from a EU 512mb HD2
its a hardware conflict between varying models, and these hardware revisions may have spilled into HTC's latest gen of devices

What to check for when gettng this phone?

I'm coming back to TMo and getting the G2x... I decided to go with a refurb on the idea that if something was wrong with it, it must've been fixed and if I get a new one, I'll get a refurb replacement anyway if something is wrong with the new one.
Is there a quick checklist of what problems to look for when checking the phone?
Mostly screen bleed. IDK know if its bad but its the only annoying thing you might find. Also, make sure its updated to latest Baseband using LG Tool to update. I'll be honest my phone had reboot issue. Since the Baseband update, I've not had a reboot and any issues are really minimal.
Thats about it. The screen and richness is what keeps me attached to this phone. That and its blazing speed. You'll be happy. Devs here have done great job giving options for ROMs. Just find best one for your taste.
Other than that, this phone is beast!!!
If you are getting a refurb be aware it only has a 90 guarantee on the hardware through T-mobile so make sure you get either the 3.99 warranty protection or the 7.99 insurance bundle since both of those include a lifetime hardware guarantee while you still have the service
As long as your device doesn't get the screen of death, or random reboots, you should be fine. Screen bleed isn't bad.
Got mine... Been a few hours and so far, so good. The only "issue" is the screen bleed (white coming from all four corners) - the only time I really see this in with screen on almost full brightness and only in that drawing app. Does this show up anywhere else?
On another hand, the phone came with a damaged battery cover. The edge by the power button is pretty much raised at almost 90 degrees - should I perster TMo for replacement or will they tell me to pound sand since I got a refurb?
Also, what exactly is the screen of death? Cursory search doesn't really turn anything up...

I think you're referring to the "sleep of death" which is when the phone goes to sleep while the screen is off and wont wake back up, this requires a battery pull.
