[Q] The proper way to power down an epic

I've noticed with the new update that there is a haptic pulse after the phone finally shuts down. I have gotten in the habit of ripping out the battery to exchange it for a fully charged one before the phone does the final power down feedback.
So I guess my question is, what is happening from the point where the screen turns off until it actually powers down fully? Are there any negative consequences for pulling the battery prior to the phone fully shutting down?

If you shut down in the dark you will see that the screen is not actually off. In fact if you touch the screen before the vibration, the capacitive buttons will light up again. I would wait for the vibration before taking out the battery, but some people do a battery pull just to pre-odin shutdown... for what its worth.

I've noticed the haptic feedback at the end of shutdown.
I mean I would personally wait. Don't think it has ever been good to yank a battery on any device while it's shutting down.

Its been like that since dk28...I think its a froyo thing...
I've never pulled the battery while it was shutting down...that's like unplugging your computer while its shutting down..

uh oh. i have never shut down prior to removing the battery. when my batt gets low, i just flip it over and yank the battery while its still on. i would never do that to my computers, but i never gave it a second thought until i read the analogy above. crap.....

If you set your keyboard timeout to same as screen timeout then the capacative lights will stay on till it vibrates.
FROZEN EPIC

Pulling the battery during shutdown shouldn't effect anything major as long as you still have journaling enabled. Those running ext4 with the no-journal mod are the only ones that really have to worry about problems occuring because of pulling the battery.

I'm no developer/hacker, but I'm pretty sure DiGi is on the right track here. The only reason to worry about pulling the battery rather than "properly" shutting down would be if you have apps/utilities/settings that aren't saved yet. If you always ensure that your apps, games, etc. have saved anything "important"--or simply closed--then you shouldn't have to worry.
Conversely, if you pull the battery in the middle of an epic Angry Birds session, you'll probably lose that progress!
Comparing our smartphones--and most solid-state devices--to a computer is somewhat misleading anyway, because PCs often have data stored in caches on magnetic HDs that require some time to write the cached info to disk because of the moving parts (platters and read/write heads). Our Epics and the vast majority of handheld devices use only solid-state (i.e., no moving parts) electronics.
As for RFS versus EXT4, that's over my head. Thanks for the input, DiGi.
If anyone else can correct me or explain anything better or in more detail, please throw down! I'm all ears when it comes to geek knowledge...

DO NOT PULL THE BATTERY DURING SHUTDOWN AND BEFORE THE VIBRATION. Learned this the hard way as on three occasions I had to restore because of FC's of all of my apps. After finally retracing my steps, I realized that I was pulling the battery before the final vibration in the shutdown process. Haven't had the problem since I put two and two together.

Agreed, I've had significant data corruption (apps force closing, files that won't open) after accidental battery pulls on the dk28 roms w/ the no-journaling mod. It makes me wonder if the no-journaling mod is worth the slight increase in performance/less write usage. Speaking of which, does anybody know if cwm3 automatically removes journalling, o just specific roms?

[Q] Wildfire Screen Issues....HELP!!!

I have a weird problem with my Wildfire's screen after I did an OTA upgrade to Froyo.
First, the top of the screen stopped working. The taskbar wouldn't work and I the top wasn't responding. All of a sudden, after approximately a month or so, it started working again.
It worked fine for a few weeks and then the right side of the screen has a problem. All of a sudden it started automatically hitting the spot on the screen where the letter "P" would appear on the keyboard. When I was trying to type out a message, the letter "P" would get hit on its own over and over again. When the keyboard was not open, it would still happen.
I felt it might be a virus, so I did a hard reset. This still didn't stop. So I switched off my phone and kept it in a desk for 48 hours. When I switched it on again, this problem stopped, but the right side of my phone was not responsive (approximately 4 milimeters of it).
I can see that this is clearly not a hardware problem and has something to do with the firmware/OS. I'm not too sure what to do. I've tried flashing new ROMs on to my phone, but it remains the same way.
Incidently, when I tried flashing "TheNextSense" ROM on to my phone, the phone started hitting the portion of the screen where the "P" key would appear. When I switched back to CM7, it stopped, but the right side was unresponsive.
Is this something to do with the memory? Or is this a known issue with upgrades/certain ROMs?
Any help will be appreciated. This is driving me crazy

why do you think its not a harware problem ?
for me it sounds like it is one. (temperature or short circuit problem)

IANAHRM (I Am Not An HTC Repair Man) but I think the touch screen connector has just slightly worn loose, perhaps due to temperatures. It sits on the right side of the main board (left side of the phone itself). I know the Wildfire can survive quite a motion shock so that shouldn't be it (I hope).
Nandroid backup and restore jobs heat up my phone quite a bit, did this occur on your device as well while you were installing roms? That might explain the change in behaviour.

Nope. It's never heated up till now. This happened all of a sudden, and it gets worse with upgrades. It's like, for some reason, the phone isn't able to function properly with any ROM other than the stock ROM. I'm going to try to put back eclair on it today and see whether it works. Will keep you posted.

Because it doesn't always occur. It kind of gets fixed on its own after a few days. It's like my phone has a ghost in it

I put back the stock Froyo ROM and now the problem is 50% better - much of the portion of the screen that was dead earlier is now responding. But the rest still isn't. Any ideas? :-(

The problem that you are facing is a busted flex cable. I'm posting this thread because I have seen in the past week at least 5 people ask what the white screen is, and how to fix it. Here is a video on how to take apart your play: http://www.youtube.com/watch?v=-3n5ZfkqhzE and here is a link to where you can buy a new flex cable: http://www.ebay.com/itm/Flex-Cable-Ribbon-Connector-for-SONY-ERICSSON-XPERIA-PLAY-Z1-Z1i-R800-/180869752159?pt=LH_DefaultDomain_0&hash=item2a1cad655f#ht_1547wt_1185
The only way you can avoid the flex cable damage is to keep from sliding your gamepad in and out all the time. So basically, just try to do it if you are actually going to be playing a game, not just something you do because you are bored.
I hope this helps anyone with that problem!

Thanks. Does this mean sliding up slowly as well yeah ?

Not necessarily. Just don't do it too often. Mines lasted me since june 2011 so far.

Basically It's every time it slides. Just don't sit there rapidly opening and closing it.

I have that problem. It still works perfectly when I open the gamepad, so I don't care.

I'd order a new one soon, because eventually it breaks with it open too.

i have a different problem
first my screen would come on but the phone was on and working etc
but the screen stayed black
if i kept pressing power on button or the hardware keys it would come back on sometimes
or if i restarted the phone
but now the screen wont come on at all, i power the fone on and it vibrates
and then it vibrates again and power buttons goes blue for a short time i think to signal that doom kernel has loaded and that u can go to recovery
but that it.
phone is dead

Wow, this is a huge problem. Is this happening to a lot of launch-buyers?

I don't know what your problem is...It might be your LCD

Ah, I have this, but its only partially down the left side of the screen, about 20px

Thank you for the video, I just push the conection and works.
Sorry for my English

Sony repaired my flex cable for free, although i unlocked my bootloader with a key from their website. So if you still have warranty on your device you don't have to fix it your self and lose your warranty completely.

Using a broken phone, a life story

Hello, I've been best friends with my Atrix since a little over a year now. We have had many experiences together and our relationship has bloomed a lot with time. I confess I haven't completely looked after my phone, I'm a little clumsy, specially if I don't get to sleep enogh. So almost a month ago, after getting up very early, I was reading a notification when my phone fell. I tried to grab it but I pushed it even more. It went straight to a cornered tile on my bathroom. This was the result:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And trust me, it's much worst in person than you can see there. Surprisingly enough the touchscreen works just as fine as it always did, even the notification area works fine (the top of the screen has been the more affected area), although I can't use the front camera anymore because there's a big scratch on top of it. Also something happened to the headphone jack because I can't use it anymore. Regardless of all this, the phone itself keeps working like a charm. I have been unemployed for a couple of months now, have a couple of bad debts so I don't have any money to fix it for the time being, so I have no choice but to use it like this.
But I have two weird errors, which has caused me to write this. The first one is related to the proximity sensor. Everytime I answer a call, the screen turns off as it should, but after the call end the screen doesn't come back on and there's no way for me to turn it, so I have to pull the battery and reset it. I tried to mark the option for the screen not to turn off when I pick a call but it keeps doing it regardless, so I suppose what I should do is to try to take the phone apart and see what's happening on the inside.
This pulling of the battery has led me to the discovery of the second error which I think it's the most interesting: 1 out of maybe 20 times that I do that, for whatever reason, a random app gets uninstalled from my phone. The first time it happened I blamed the app (growlr was the first), but then I saw it happened to Twitter, then to Google Plus, then to Script Manager. And it's not like it gets deleted completely, if I go to the app manager I can see it on the list but not with the regular name (ie: com.twitter.whatever instead of just Twitter). I'm using Neutrino but I'm not sure if I could blame the system, I think it's caused from the battery pulling in the same way turning off a computer by force can produce errors on the file system.
So has any of you come across problems like these before? Do you have any suggestions?

Graphical Glitches .. !? (due to cold temperatures..?)

Hello guys , i would like to know whether anyone else has experienced any type of graphical glitches on their 6p.
the thing is , i had a Nexust 6 (Moto) last year, and during cold temperature it would get a split screen bug few times every few hours and it was very annoying.
the only fix for it was to use a custom kernel with 'interactive' governors.
the kernel that worked best for me to get rid of that graphical glitch was Lean Kernel.
but my 6p thankfully is not getting the splitting screen graphical glitch, but instead it just looks like the picture of whatever app i am in just gets smashed into each other (sorry i dont know how to explain!).
it basically glitches for a second and is back to normal , and it happens like a couple of times per day, happened only recently after the weather here got cold.
is this a common thing with the 6p? i am now wondering whether i should try lean kernel with it ,as i am currently using flash kernel.
hm, at first i thought it was because of a profile i used on my 6p so i disabled profiles, then i thought it could be caused by the theme (cm13) so i reverted theme to stock.
but the random occasional graphic glitch was still there.
hope someone can shed some light on this for me.

Only if you could explain it a lil more maybe a screenshot or something

What kind of temperatures?
Phones usually last fine till about -15 celsius, beyond that intense screen ghostings (maybe this is what you meant?) start appearing, phone turns slow in general and battery dies very fast also causing permanent damage to the battery.
If it is the screen ghosting then that is perfectly normal and usually dissapears when it gets warm again, but I can not confirm as I have no 6P nor have had any amoled phones.
Does the glitch show up on screenshots? Or is it only visible physically?

its only physically visible, i think it is because of the app Twitter..
when i open it up ,that graphical glitch appears for a split second, it looks like the app itself makes the screen shimmery? i dont know how to explain it, but yes i think it was twitter.
but then again, i think it is what you stated, screen ghosting.
and that stuff is normal ? if so then all is good, thanks!

@Prattham and @tauio111 sorry guys ,pretty late on providing screenshot.
i happen to have one where it took place, the graphic glitch.
it ocassionaly still does happen..
turned out it is not at all because of cold temp.
it is stupidly hot right now, haha.
and btw. it also happens more often when i go switching too fast between apps with the recents button.
and also at times when i scroll.(with scrolling happens way more rarely though).
here is the picture , look at how the picture in the youtube app (official one) mashes into each other.
