[Q] Help Freaking Out

Have a major problem with my screen when turning phone on or rebooting the screen looks fine. But when I get to the actual home screen it's looks crazy with vertical lines on it like a white noise effect but when I shut the screen off and then turn it back on it's gone. It's freaking me the hell out what could be causing it? Is there something wrong with my phone? Is there a setting somewhere that's out of whack? Any advice would be greatly appreciated.

sounds like a hardware issue, which ROM are you using?

Try reflashing.

I had this problem right after I flashed a kernel. Try wiping your dalvik and cache and rebooting, thats what fixxed it for me.

I have this same problem, and it only happens with certain kernels. I think it's an Epson thing. My last phone was a Novatech and had no issues and my current one is an Epson. Sometimes it's that crazy vertical line garbage, others times it's horrible tearing. It only happens after a reboot and ALWAYS goes away after turning the screen off and on. I stopped caring about it a while ago because it always goes away.

Thanks guys I rest easy now I was worried I was going to have to deal with sprint.
_MetalHead_ You the man.

No prob man. With my last phone I was very limited with which ROMs and kernels I could run. It wouldnt run any AOSP ROM and most if not all HAVS kernels were a no-go. My current one will run anything I want it to run, and runs MUCH smoother and snappier than my last phone. So, I deal with the weird screen thing and I get a phone that blows the socks off my last one. It's a fair trade off IMHO.

Ya I got worried as I'm still at noob status with this whole rooting thing and thought I fried my phone. I tried searching the forums but couldn't find the issue anywhere I had talked to sprint and they told me that it was a hardware issue. Glad that its nothing to worry about. I'm loving the boosted speed that I get from my phone.

Are you running a custom ROM/kernel or are you still stock?

Running cm6.1

Yeah, definitely don't worry about it then. If that's the only issue you're having then let it go, it's not a big issue at all
Have you tried MIUI yet?

No not yet.
Sent from my PC36100 using Tapatalk

Well if you are a fan of AOSP then I recommend at least trying it. I thought I was going to hate it but tried it on a whim and have never looked back.

This is a fairly common issue with cm6.1 rc1.
There's a thread in the cm forums where multiple people are getting the same thing. I would post the link, but apparently I'm too new here.

When will the first update be out ?

Currently a Nexus-S 4G owner, thinking of getting the GS II, but keep reading so many issues with WiFi...Network/Radio...SMS text problems...I am scared to upgrade to the S II, until an update/patch is released to fix these issues I have read about.
Also my Nexus-S has pretty crap WiFi signal already, in my house with a great WiFi setup, it drops way too often, my EVO 4G was rock solid always connected.
Any news or opinions on this ?

Honestly, I haven't had ANY of these problems. Maybe I got one from a different batch because I was backordered.
My phone seemlessly goes from WiFi to 3G and back again without any intervention from me, in weak OR strong coverage areas. To my knowledge, all my texts have gone through.
I just rooted late last night (with the stock kernel), and so far I haven't had any issues, either.

No issues what so ever trust me. Ask stock phone. Always on wifi when at home. Wifi turns on and connects super quick. text calls come thru right away.

I agree 100% with your sentiment IRT the thread...but, I had 2 LOS in the 5 or 6 days I was rooted. I rooted and had another 2 over 2 or 3 days. Stock kernel reinstalled and I've been good so far, but, I think blaming the kernel is foolish. The problem occurred before I rooted and after I rooted.
Does the fact that I am now rooted with a stock kernel and haven't had the problem suggest to you that only rooted stock-kernels are without fault?

You guys know that you can have everything stock, including kernel/rom/recovery, except the rom would also be rooted by addition of su binary/apk/busybox?
I haven't had any los or any other severe issues before or after I rooted the phone.
It may be that since I live in a small university town, my towers aren't getting upgraded to rev b, but yours are. These issues may not have anything to do with the phone at all. Maybe it has something to do with the sprint maintenance timing.
Or maybe it's because some people bought their phones from third-party retailers, and the phones weren't properly activated.
Or maybe it's some commonly used app that people with problems have installed, and I and others don't have installed.

I've had minimal to no issues personally. And I've had none while using stock Kernel. Using i9000 kernel I had a few LOS, but infrequent.
I also owned the Nexus S...and this is BY FAR a better device from a connectivity comparison.
Remember that the complaints you see are misleading...in that people are more apt to post about an issue, versus those that don't. It's human nature.

rooting or not has NOTHING TO WITH THE ISSUES!!
- I have had a stock phone since the day it came out, and have "watchdog lite" installed, watchdog alerts me about 10-15 times a day that "suspend", "events/0", and "base system" in my phone are using over 50% CPU while the phone is sleeping... LOL, it JUST happened again while i was typing this...
- also had the LOS issues 2 times, has to restart the phone to get signal again
- once, i was in a call, and when i went to "end" the call, i could not click the end button... the other side wud NOT hang up because it was customer service, they r not allowed 2 hang up on a person... so i had 2 restart the phone to fix this
- sometimes i click the power button to wake the screen, n nothing happens for about 5 seconds... so i click the button again, and the screen turns on and back off right away... n den i have 2 click the button a 3rd time to wake the phone...
- sometimes app just close randomly, and if you try to open the app again, its begins from the VERY BEGINNING, so w.e. u were doing in the app is lost... this sucks for games, and if ur in the middle of something important
- when the phone is on charge, the keyboard sometimes acts weird, typing letters u never click... and also u have 2 touch the screen 2wice sometimes 2 make selections... only happens when on charge, u take it off charge, n its back 2 normal right away
cant think of anything else as of right now... but there are some issues in the phone that can most likely be fixed either via root, or thru a sprint update...

I had the nexus s 4g and due to the antenas that phone was practically unusable especially on wifi. The gs2 doesnt have any of those issues. This is the first phone since the evo 4g that has impressed me snd i have owned the evo 3d and photon as well.

I seem to be having an issue with battery draw whenever wifi is on.
I'm not rooted, my phone is 100% unmodded. I haven't even installed a different launcher.

Im hoping for an update so my games dont continue to crap the bed 10 mins into them. Nothing like trying to lvl up in nova and never finishing an online match.
Sent from my SPH-D710 using xda premium

LOS can occur with or without the root. I've only experienced it once but it was in an area with good coverage and no one else with Sprint phones at my office encountered it when I did. It only happened once but I do NOT have a modified ET4G - it is stock. There is a detailed thread on this on android forums and it can occur with or without a root. Apparently it was listed on android forums or android police that this is a known issue. I don't use wifi but it seems to be a common issue for people using wifi from what has been reported.
That being said, I would highly recommend this phone to anyone looking to get a phone.

Yeah... you would think that being unable to handle games for more than 10 minutes would have been something that the engineers would have caught during development...

I have had no issues either. I had one LOS after I flashed the rooted kernel. Went right back to stock kernel and no issues since. And none before the rooted kernel either.

My phone is messed up

About 6 times a day, the capacitive button on my phone will randomly get pressed by the phone. I'll be holding the phone, and the phone will go crazy. There is no rhyme or reason why it occurs; it just happens. other times, it will just vibrate, and menu items will open and close. I can also feel all the haptic feedback when this is happening.
Sometimes it ends calls, sometimes pushes the menu button like crazy, and eventually locks the phone up for 5 seconds. I can remedy the situation by turning off the screen.
I took the phone in, but was unable to replicate the issue for the rep to see. He tried for 10 minutes and gave up. I wanted to let him know I wasn't just making up stuff, so I tried in store for 75 minutes. (Just so you know, its not related to too many running apps. I have already tested this) He then told me on my way out to brick my phone so sprint would be forced to repair it, which I do not want to have to do.
So I called up tech support. and whats typical of Sprint is to find everything else to assign to blame so they can just call it a day and not have to do anything. The newest blame is being put on the Network Vision upgrade since I live in Chicago. I have 6 lines on my family plan, and none of the other 5 phones are having any issues. Now tech support is telling me to go back to the store. The phone is driving me crazy now. I've reset and reflashed the phone to stock EL29 numerous times and the issue wont go away. I've also deleted everything on the internal SD card. I've reset via ##786# too. The phone is just plain screwed up.
I have TEP. What should I do at this point? Is anyone here a tech?
Thanks.

I'm not a tech and not trying to be smart, but have you tried flashing non-stock EL29 based roms, like Calkulin's or Blazer's? I would try other roms Gingerbread or ICS, just to rule out any software issues.

yes. i used to be on Calkulin's when this started happening (about a month ago), so i went back to stock, and the problem persisted.

So you're saying this didn't happen before flashing Calkulin's rom? I would keep trying other non stock roms (even ICS roms) to make sure. To install ICS roms, you need to flash EL26 CWM5 kernel (Gingerbread), then the rom. Also flash Calkulin's format all.zip (you may have already done this), because it wipes data, cache, as well as system partition. Factory data reset does not wipe system partition, I believe (I might be wrong)

Happened to my old E4GT. Menu button kept pressing itself but then it got bricked and replaced ;p

Had something similar happen with my first Pre years ago. I'd get woke up in the middle of the night by my phone performing weird activities and then awoke one morning to find it stuck in airplane mode and unwilling to be coaxed out of it.
Took it to the local store (was a corporate store at the time) guy was super nice and swapped it out without any hassle. Man do I miss that store. :-(

I have the same issue with my phone. I thought at first it was some sort of corruption on my blazer Rom, so I flashed multiple other roms with the same outcome. I haven't tried taking it to a store yet, but if this problem gets any worse, I might just have to use my tep for once.

This was happening like crazy when I was on the latest Calkulin ROM. I switched to CM9 and it was still happening. Menu kept popping up, phone would randomly reboot and sometimes the screen would just go black without shutting the phone off and I could not wake it up without a manual reboot.
Today I used sfhubs One-Click for stick FD19 and haven't had any issues at all. So far my phones been rock solid for at least 12 hours, whereas before I would have seen these issues pop up several times within that time frame.
lets just hope it stays that way

I've heard this was happening in low signal areas. What was the signal like when it started?

Yup mine is doing this too. I bought this phone used on craigslist about two months ago and it started acting up about a week ago

Messed up
I am a lead tech at a corporate store fairly close to you (a few hours). If I find no evidence of corrosion or other liquid damage, I would be happy to order a replacement for you. Your disadvantage would be time to get here, and since seed stock is incredibly rare for this device, the trip would likely have to be made twice. PM me for further details.

This happens to me too on blazer 4.0 and blazer 4.1.... ITS very annoying

Just got mine replaced and the brand new one is doing it stock. Usually when the battery gets below 30%.

You beat me to the post. It still happens on ICS in low signal areas..on 3g and 4g. It must be a flaw. I have tried it in known dead spots on about every ROM since launch. As soon as you get on the edge of a dead or very low signal spot, a random vibration then menu Popup or recent tasks on ICS.. its frustrating

i am not in a low signal area at all, and I have tested this theory

My phone did this once a few weeks ago. It was only the menu button and I was on the main home screen so it kept popping up the menu options. Shut it down and restarted and it hasn't happened since.

I have the EXACT same problem! I have concluded that it only happens in low signal areas, and it only affects some phones. Its EXTREMELY ANNOYING! I mite get mine replaced, being that my sprint store is very reasonable. What I do is put the phone in airplane mode when I'm on wifi and use Google voice for texting. This fixes the problem immidiately but only works until you turn off airplane mode. Let me know if that works.

I'm pretty sure this is a Samsung phone issue in general. It happens in low signal areas. My E4GT does it occasionally, and my fascinate used to do it as well.
Though, I will say the e4gt is not nearly as bad as the fascinate was. If you were in a low signal area with that phone, it was literally unusable because it would back out of everything you tried to do, or the settings menu would keep popping up and closing.
I've had the menu button pop up on the e4gt and a few phantom key presses in low signal areas, but nothing near what I experienced on the fascinate.

Random reboot issues

Is anybody else getting random reboots on their SGS3 (AT&T)? A couple times a week I hear the SGS3 boot sound from my phone & find it rebooting. Maybe once or twice while I've been using it, but usually while it's doing noting sitting in my belt pouch.
Bone stock, I haven't rooted it or anything... yet (probably soon now that the IMEI issues or at least backups & restores are sorted out).

No random reboots here. Might want to exchange it.

when i first purchased my phone I was constantly having the same issue. by re-installing a couple of the stockish roms, i have yet to have a random reboot on the device.

Ya, that's kind of what I've been thinking about. Figured I'd post here and see if anybody else was getting similar results as I've been lurking for quite a while and haven't seen any other complaints about it.

No. Not lately. But I did have this happen. It could really be some of the applications/tweaks conflicting with each other. I also was not rooted when this happened. But one day it just stopped and has not happened in while. The only thing that changed was I started deleting apps because I had so many.

I have reboots. Discovered my power button occasionally sticks in the closed position.

I get occasional reboots. No where near as bad as my Captivate was,but I do get them without any kind of coherent pattern.

[Q] Epic Touch 4G will randomly reboot by itself as soon as I wake it up

Hello,
I have been fairly involved in following this forum, and I think it is undoubtedly the best resource for this phone on the internet. Take a minute to hear my plight:
I bought an ET4G the day it came out in the States. I have tried several custom roms and play with kernels all the time.
About, I'd say...2 months ago, the phone started rebooting itself once a day. Sometimes, the screen lights up by itself while the phone is sitting untouched! The problem got progressively worse, until the phone was rebooting 15 times a day. I installed a fresh stock ROM (rooted), a NEW battery, and the problem went away but started to slowly creep back. At this point, I went back to the stock kernel (was using Agat's), and the problem STILL HAPPENED.
So, I installed a fresh stock ROM, this time unrooted, kept TouchWiz instead of Apex, and did not install any freaking apps, except for the BARE minimum. This time the phone did not turn off. It seemed to have fixed my issue. My speculation was that my phone, for some reason, didn't take the voltage under load quite well. So, I spoke to my friend (who is a Store Manager at a corporate Sprint store,) and he was very kind to help me out in getting an exchange so that I could use the phone the way I was using it (after all, I was still within the 12-month warranty).
It's now been 1 week, and the only modifications I've made have been to install Agat's kernel. THE PROBLEM HAS COME BACK in the replacement phone. So, as a last resort, I undervolted the damn thing -50mV, and even went ahead to underclock it using ExTweaks to 1100 MHz. STILL HAPPENS. I go back to stock kernel, uninstall all tweak apps, STILL HAPPENS.
So, I install a fresh ROM, it gets fixed, gets progressively worse, and then THE PROBLEM COMES BACK.
I'm going crazy, XDA. I just want to have a working phone until July 1st when I can upgrade. Is there any way I can diagnose what exactly the phone is doing when it reboots by itself, and what it's doing when the screen wakes up by itself when untouched? Other tips, suggestions, or anything else that could lead to a resolution?
Note: The phone reboot slightly less often when using stock kernel vs. the latest Agat kernel (0.6.7). It also appears to occur less often when I use default touch-wiz. Lastly, the problem goes away after a flash for almost 24 hours, and then it starts creeping back.

Why did you use undervolting as a last resort if your phone had problems? It would only make things worse

I mean, I've had the new phone for a week. I haven't done anything crazy with it, and it's already doing weird stuff.
I never over-clocked either of the phones, and once I learned under-clocking was known to help, I tried that last.
There has to be a way to diagnose this thing:
I've been monitoring the last seen services before shut-down, and the last 2 active services on the last shut-down were:
1) [dhd_dpc]
2) system/bin/surfaceflinger

My phone did that and I ended up getting a replacment. Stupid referb had a problem with the CPU. New phone works perfect

I will return the phone to the store once again in hopes that a replacement gives me a better experience. I'll report with updates.
