Full brightness screen flicker

Recently I have been noticing vertical lines/interference when viewing a mostly white screen while on full brightness. Is this a sign my epic needs a visit to the repair shop?

I have the same issue, it happens a lot when I'm using the browser.

Sounds like screen burn in, a fairly well known issue.

Is that covered by the warranty cause the screen gets super hot as well I can't imagine what its doing to my battery life

If it was screen burn in you would get those lines all the time.

Its the only problem with Super AMOLED screens, and what is fixed in Super AMOLED Plus.
Sent from my Epic 4g thats perfect in stock form.

That's odd I don't remember it ever happening before recently oh well its still bright as hell on low anyways but it will suck outside as that's the only time I up my brightness I wonder if its a power issue with the cpu as it only happens most during processing market or web pages

This is an engineering flaw. When the voltage from the battery drops, when it is not fully charged, and the screen brightness is at maximum, and the screen has a lot of white pixels drawing power, the display controller loses power, and has trouble with sync.
The battery will also drain slowly, when the brightness is set at max, even when plugged in and supposedly charging. This is even more critical on USB charging.
These problems are hidden most of the time, with the Display/Power saving mode, and dimmer screen settings.
It seems the full brightness is not properly designed and powered, and this is a shame, because it really makes the Epic 4G's display stand out.

Lol! I just had this problem crop up on me today for the first time, and I thanked this guy because he described it exactly, low battery and all, but it was his one and only post from a year ago. Well, still, thanks. I hope you read this someday.

Maybe there was a reason for it. Maybe it saved a new thread being created that didn't need to be created. Maybe there was humor in it. You never know...until you read the thread.

Well, I wouldn't be surprised if lowering the voodoo rgb settings worked. It just wasn't the answer I was looking for.
I like my screen colors the way they are.

Its most definitely a hardware issue. My last epic didn't do it. But this refurb does. Either way, we should stop posting in here I guess lol. Let 'er sink.

Capacitive menu button activating by itself

So a few times a day my phone will start bugging out, vibrating and the same menu that would pop up if you pressed the menu button would come up. I find it pretty weird, I can't reproduce it but it comes and goes.

This kinda sucks because I have a feeling it's a hardware issue, I'm over my 14 days and I'm scared that I might get a phone with LOS. Damn I thought I almost got away with a problem free epic.......
Sent from my SPH-D710 using Tapatalk

Same is happening to me, I made a thread about it and no help, might be a hardware issue.
Sent from my SPH-D710 using xda premium

tonight mine freaked out a little bit but not exactly the same as yours. My phone appeared to freeze up for a few seconds and then anytime I pressed any of the capacitive buttons the voice talk app would say "what would you like to do?" I had to reboot it to get it to stop.

I Google's it a bit and it looks like others have this issue as well. It used to only happen once a day but lately it's more often. Issue seems to be getting worse. I know for sure tho when I bring it to sprint it won't happen at all and I'll have to argue with them.

sorry for ressurecting an old thread. but anyone with a fix for this? i swear this hasnt happened untill like my 15th day lol..
someone help!

Im having the same problem.. But I can watch my menu open and close on its own. I cant figure it out to save my life. I got this oct 15th its now nov 4 th.. If I go to our sprint store & get a hassle, someone will be eatin this phone..

Well front desk girl almost ate this phone.... I felt kinda bad abt it afterwards.. Repair guy stayed behind the glass window... So after some pressure, they decided it was a hardware issue with the touch screen, an replaced the phone.

Yea, I get this issue every now and then. Some of the ROMs give me less frequency, but it always seems to happen again.

congrats on getting a replacement. unfortunately, im outside my 14- and 30-day period so i suppose im stuck with this issue

anyone with any more info on this? Mine starting doing this recently.
Factory Reset was a no fix.

This started happen to me too, my home button gets "stuck" when i press the power it would take a screen shot. I hope its not a hardware issue, i really baby my phone. I am calk rom 2.0. Also i belive samsungs warrenty should cover it for free.

Call screen going black

Just a little heads up, I don't know if anyone has faced similar problems, but I just had to replace my phone on warranty, because as soon as i place a call, the screen would go black, and never wake up, leaving me unable to hang up or work automated systems
If I was helpful, give thanks

That would be my guess. The phone goes black so you don't press buttons with your face and is supposed to come back on when pulled away...for those that were not knowing what the issue was

It indeed is. As I noticed that the screen will come on if I put the sensor right next to a light bulb, but goes dark the second its even 4 inches away from the bulb

Phone won't boot, vibrates

I cannot turn on my phone at all, the Samsung logo comes up, screen blacks out and the phone just vibrates once every couple of seconds. If I'm lucky the phone will sometimes boot up but freezes and turns back off. It's nearly impossible for me to boot into recovery and do anything as the phone shuts off seconds later. Anyone have any advice, I've looked all over and only found one other person with this problem and no fix

Are you doing the combo correctly, release power after vibrate continue holding volume keys? Did you drop the phone causing this? Try pulling battery first then try recovery

yeah, that thread had helpful info. i tried the one guy's suggestion of gently working a tiny flat-head screwdriver around the power button, and it fixed my issue.
hopefully it won't come back too often, but at least i know what it is (faulty power button) and can send it in for repairs if need be. at this point, i'm just relieved i have another chance to backup my data!

well, the issue came back, and working a screw driver around the button isn't solving the problem. it'll go away for a very short period of time, and then come back.
more recently, i've started losing settings for open apps when the phone reboots randomly. freaking awesome. just lost my handcent settings, and can't figure out where the config file/db is so i can restore it from a backup. looks like i'll have to spend another hour or more fully customizing the blasted thing again.

Its gotta be a bad motherboard I had same issue and Samsung warranty it out and fixed it for free or you can find em on eBay i just bought a used one for 90 and works perfect
Sent from my SAMSUNG-SGH-T989 using xda premium

Power button could be stuck again. I fixed mine my flicking it with my finger every second and finally my phone would start up again. Guess screw driver would have been easier, haha. Would work for a month then the same issue would start again. Do you happen to use a D30 case?

Its in apx mode, full on brick. Needs a new motherboard or repaired by Acer.

The person who I got it from advised it has already had its motherboards replaced by acer... I don't believe they tried to root or flash anything... It belong to a middle-aged wife... Is there anything that could have caused this

Read through the brick thread, its exactly what happened to yours. In short, Acer uses a faulty memory module and it dies at random. Some say even out of warranty it may be possible to get Acer to repair it, the case needs elevated, but as you didn't originally purchase it, that wouldn't be particularly ethical, but worth a try if you want.
