I would suggest you to go to service center

My device dosn't have grantee.

How did oil get under the display?

if ur device was under warranty as well then also u will have to pay for it as it will not be covered under warranty

Oild case fall out and drop into phone via calling speaker.
I have not any money to pay for it.please guide me

1- Turn off your phone and remove sim card tray.
2- Put uncooked rice in a deep bowl or small bucket.
3- Put your phone in rice while sim tray is out. Your phone should be fully inside of rice.
4- Wait at least 48 hours, then check your screen
This is the best way to remove oil, water from cellphones

I use heater but oil doesn't get out.please help me

Any updates? My screen have the same problem after using cafele's oil to remove airlift.

[Q] What phone is this?

All I'm able to tell is that it's a Samsung device, and it may be GSM because of the microSIM slot I see on the back. The back had no battery, no cover, no SIM, the screen is clearly decimated, two capacitive buttons missing (it takes talent to break capacitive buttons) and most buttons are pretty much loose.
I may spend a little money to get this thing fixed up, assuming it even turns on. I planned on getting a battery to test out first, then if it worked, fixing up the phone and keeping it or selling it. Not anytime soon, since I just bought a Nexus 4 while already low on leisure money, but it would be nice.
From the picture you provided and the detailed description it appears to be a Samsung Epic 4g.
If your interested in some replacement parts for the device I would recommend taking a look at these parts www.globaldirectparts.com/Samsung-Epic-4G-Replacement-Repair-Parts-s/6425.htm.

Then I warmed the back of phone and suprisingly it worked. I installed the new rom with native sd and start to working used some application. Than when I plug the battery door Screen goes away. Phone and digitzer are working.
I unplug the battery and searched for anything anormal but there is no bad looking. Than I give my phone to repairman. It warmed and and make it runnning screen. But this time upper part of screen is looking bad. There is lines and blue colors in mglrd mode.
Also Afterthis workings magldr not running. It is opening the menu but any of the loodings not working only say 1234 go go go and freezing.

What area of back did you warm up & was the back cover & battery off when doing it ?

Severe Drop/Fixed my device

Was testing out my Desire X's camera and my butter finger'ness came back and it slipped, smashed the ground. The screen looks fine, it just smashed open st the bottom. The battery doesn't really fit in properly, but if you push it in hard it fits in properly, but the device doesn't turn on.
There is also this two clips, does it have anything to do with proving battery power?

My question is, can this device still be recoverable as its not as bad. And I had paid money for it. Cheapest way to fix this? I've tried pushing everything into place but it just flings out.
When connecting the device to the PC it has a blinking led at the top which is red. Which blinks on and off.
Edit - the device turns on just fine oo freaking strong device.
Yeah, should be fixable. I think you'll need this as replacement and hopefully it will work fine then. Didn't test myself, I only had to replace screen assembly some time ago, but this part is easy to replace, provided that you've got the right screw driver available.

Water damage; Only charging seems affected. How to check/repair?

My so left it on the kitchen dresser. When I picked it up (because it was bootlooping) the water came dripping out. I think most of it was in the seams between the cover, but there were some substantial drops in it, but only on the plastic parts.
I placed it immediately in rice to dry with the back removed. It still booted afterwards, and everything seemed to be functional (wifi, rotation, camera etc.). Only charging doesn't work. Ran battery endurance test to heat it up a little extra, but charging still doesn't work.
I see some corrosion a little above and to the left of the battery. Other than that I cant spot anything unusual. How do I check which part is the problem?
Yikes.
You could... send it back to HTC, and let them tell you what is wrong with it, then perhaps buy the part yourself and install it.
With any electronic, I would disassemble it and assure that every part is clean & securely fit.
Maybe the smart chip in the battery shorted? Maybe only the battery needs replacing. I have no idea how to confirm that.
Good luck, man.

Busted Screen Replacement Question

Hey all, so this happened earlier today.

}
And it got progressively worse and now I can't see anything. Was looking at replacements and was wondering if I needed the replacement screen and digitizer with or without the frame assembly?
Anyone deal with this before?
Thanks!
Not familiar with that phone but any impact great enough to break the display can cause internal damage. Direct contact isn't necessarily needed as high G loading can damage chipsets internally by breaking bonds.
In the future use a good case to help lessen the G force loading when dropped. Urethane/polycarbonate cases like the Zizo Bolt do well and can even enhance usability.
Use -all- OEM parts, and replace the battery if older then 6 months or if it shows -any- sign of damage. Best to use a ESD mat/wristband and observe all ESD handling protocols especially room RH ie >40%. Once the individual assemblies are out of circuit they are much more vulnerable to ESD damage.
