Been spending a lot of time searching for a fix to this. I'm sure its been covered before but I can't find anything specific to my problem.

android.process.acore has stopped unexpectedly. Force Close.

This is on the viewsonic gtablet, Tnt root I believe it was called. Worked fine for a week or so and then all of the sudden I can't do ANYTHING without this force close coming up. When I say I can't do anything I don't mean I get this annoying message I have to x out of, I mean I can't do a god damn thing. Can't open settings, can't open the internet, can't open my contacts to delete them as I heard that might be the problem and I don't need them on my tablet as I them on my droid X. Just about the only app that I can get to work is Kindle.

Any ideas? If somebody can just tell me how to do a factory reset by pushing X Y and Z buttons that would be great, i'm about to throw this thing out the window.
[Upgrading, Modifying and Unlocking] Joekak:
Power and Volume + will do a recovery key reboot... Otherwise, check out the gtablet forums
[Upgrading, Modifying and Unlocking] bigtex06:
Sounds like it is time to put a different rom on there. I would suggest vegan tab rom get his latest . Vegan tab ginger edition. http://vegantab.gojimi.com/

You will have to install it through clockwork mod , which you should have if you already put a different rom on it. Follow his instructions. I have tried just about all of the roms that I could find . This one works . Good luck . If you hit a bump message back.
[Upgrading, Modifying and Unlocking] bigtex06:
I just found this rom and it works great . Very smooth and everything I tried so far works. http://xdaforums.com/showthread.php?t=1119888

[Epic 4G General] capt_peo:
I wanted to update to CM7, once it rebooted into recovery mode it gives me an error. I got the official Sprint update and the same thing happens. Once it verifies the file, something happened and it says there was an error and does not update. I did a factory reset on the phone, got the official sprint update and the same thing happened. The error is always "signature verification failed" on both roms.

What can I do?

Thanks.
[Epic 4G General] decalex:
When flashing a rom, are you selecting 'install from SD" then find where you saved the zip, etc?

It sounds like you're trying it thru the update.zip option (don't do that). Also, when you reboot into recovery, you should be seeing orange type clockwork 3.0.0.6 (not blue or green).

Ask if you have any other questions.
[Epic 4G General] silver03wrx:
Are you using cwm 3?
[Epic 4G General] capt_peo:
Thanks for the replies guys.

I am using clockword mod 3, with their option on updates.

I don't know how to do the "update from sd", haven't seen that. I'm not sure if I am seeing the orange you mention...I just go to restart in recovery mod from CM3.
[Epic 4G General] 063_XOBX:
If you don't see orange text you're not on CWM3, you are either on CWM 2.5 or stock recovery and neither of those would be used for what you want to do.
[Epic 4G General] decalex:
Ya, check out the development section on getting the latest clockwork, if you don't have it already. And just in case, first, try powering off your phone, then hold camera button, volume down and power (after device is completely shut off). If you don't see orange text, you should update to the latest clockwork.
[Epic 4G General] capt_peo:
I turned off the phone, turned it on with the vol down/camera button and it automatically booted on CM recovery 3.0.0.5. Doing a rom backup. Then I see the orange text with several options but I can't pick any of them...I'm hitting the "home" button but nothing.

The phonr wont respond...I can toggle between the options but thats it.
[Epic 4G General] capt_peo:
I turned off the phone, turned it on with the vol down/camera button and it automatically booted on CM recovery 3.0.0.5. Doing a rom backup. Then I see the orange text with several options but I don't know where the hell CWM downloaded the file!!! I cant find it, or the official 2.2 one...

And now the phone is stuck in the SAMSUNG screen...
[Epic 4G General] capt_peo:
Bricked...tried factory reset and nothing. Tried restore through CWM and nothing...
[Epic 4G General] JPhantom95:
If you are able to get into CWM or download mode then your phone is not bricked. It sounds like you will have to use ODIN to restore your phone back to stock.
[Epic 4G General] arashed31:
ClockworkMod 3 automatically converts your phone's filesystem from RFS to EXT4. You need a ROM that supports EXT4 or else it won't boot.

You wanted CM7 so go ahead and flash that if it's on the sd card. If you don't have it on the card it's easy to fix. Just turn off your phone and plug your memory card into a computer and copy a ROM that supports CWM3.

Once you flash a ROM your phone should boot normally.
[Epic 4G General] decalex:
Bro, when u boot into clockwork (orange) are u opening the slider and using the arrows and enter key. ? You shouldn't be using the home key.

Don't be so quick to "I'm bricked" .. cuz that's rarely the case. And annoying when ppl are trying to help.
[Epic 4G General] capt_peo:
K, thx for being patient. I did Odin and its again working.

Now the phone updated to 2.2.1

For future reference, can this Odin method be used o update to a non official rom (like CM7)?

Thanks for all the help.
[Epic 4G General] decalex:
I wouldn't rely odin for that, and as far as I know, no. For frame of reference, I've probably flashed epic roms over 100 times, and have only odin'd 5-- Used mostly to return to stock/update a modem. So, odining probably wasn't necessary for you. Do what arashed says a few posts up.
[Epic 4G General] capt_peo:
I'm using SRF 1.1.0/Twilight Zone and its amazing. Battery lasts a lot longer too.

I can access the Android Market, but it will not download any apps. It starts to download for half a second but then stops. I have used the "BOYPPC-SHIFTPDA GINGER 2.3.3 V5 " and "AmeriCanAndroid" ROMs and have the same result.

I have deleted cache and data from all the programs that start with Google and Market but I still cant download any apps. Any tips on what I can do to fix this?

[Xperia Arc General] kiwi45:
Just got the phone 2 days ago and the battery life does not look very promising. Phone can only last about 15hrs after a full charge with light wifi/3g usage and no auto sync. Quite disappointing.
[Xperia Arc General] mith500:
I remember my X10 having the same problems when I got it, give it a a few weeks and it should start giving you better battery life. If that doesn't solve it, I remember a firmware update for the x10 that came out that improved the battery life a lot, so maybe they could do that for the Arc.
[Xperia Arc General] Focal86:
The battery should improove, I got mine on Monday.

I charged mine on Wensday morning and it lasted until Friday morning, with backround

sync on, 2G the first day, 3G on all second day, some sms, listning to music and a call

both through skype over WiFi and normal, both calls lasted over an hour.
[Xperia Arc General] syl0n:
I read somewhere this phone doesn't have "Auto brightness"? maybe this is why battery is poor.
[Xperia Arc General] Shutterspark:
It does, it's just subtle. You have to actually be looking for it, and there's no way to disable it.
[Xperia Arc General] Retrosid:
Does anyone know if there gonna be released a battery for arc with higher mAh?

Which battery does the model includes?

Also I saw BA750 with 1500 mAh.
[Xperia Arc General] r1200gsa:
I'm having a similar problems with Battery life, gets to 7% within 14 hours - not what I expected since the battery seems fairly large.

I have wifi on, GPS off, bluetooth off, Push email on, a number of calls through the day. Very disappointing at the moment.

I remember somewhere reading about how to charge the battery properly, I did it on my HTC Desire, it probably gave me like another 20% after doing it - if anyone knows please let me know... I think it went something like:

1. Charge the phone whilst the phone is off

2. When fully charged pull the power and turn on

3. connect the power again until fully charged

4... can't remember the rest or even if the above was correct?
[Xperia Arc General] refract:
If you want longer battery life for the times when going near a electric socket is not an option, just do what I did whenever I went travelling somewhere - buy an additional battery, charge it and keep it in your bag or whatever, and then just pull it out when your battery dies.

As for battery life of smartphones in general, I had pleasure of toying around with x10 and my x8, the battery life fluctuated at times. In the start it barely lasted a day or two without usage, now my x8 can usually go for like 5 days without charging.

It's deffo very weird, but whatever.
[Xperia Arc General] r1200gsa:
That's a good suggestion - however it isn't really what I am after, I need my phone to last until bed time before I charge it.

Now I know this is a new phone and we all go a bit nuts when we get them, using them heavy, seeing what they can do etc - buy yesterday I made a point of using my phone exactly how I normally use my phone (once the novelty has worn off) and the battery life is POOR! :(
[Xperia Arc General] refract:
Yeah well, in my experience, battery tends to start being a lot better after a week of owning a device, at least when it comes to mobile phones.

I'm not the type of guy who acts like a little child when he gets his new toy ( in this case, a mobile phone :D ), so I'd like to believe my experiences can be used as sort of a benchmark in these cases.

As I said, both x8 and x10 batteries lasted very little for me in the beginning, gradually expanding later on - x10 could last 2-3 days without charging with just moderate usage ( SMS, maybe a bit of web browsing + few phonecalls ), while x8 would last 3-5.

Just report back a bit later if the battery life improved a bit.

When I get my Arc after it gets released here in Croatia, I'll do my own review of it.
[Xperia Arc General] kiyu727:
Im usually really positiv about anything I buy (since I inform myself about possible disadvantages) but the battery life sure is not good at all.

Its ok, but cant call it good.

Still the device itself is quite astonishing.

Edit: switching to GSM only has given me quite a boost in stamina !
[Xperia Arc General] xilw3r:
and that my dear friends is another reason why i want a neo :) 23% smaller screen ... more pocket friendly lol.
[Xperia Arc General] kiyu727:
and thats the reason why I got myself an Arc, larger screen and not chubby ;-)

Sent from my Xperia Arc.
[Xperia Arc General] DaddyDan:
I'm finding the battery life better than my X10 so I'm more than happy with it!
[Xperia Arc General] xilw3r:
touche.

that chubbyness of neo aint no chubbyness :P its 13 mm thick in the fattest place which is still not much. my mom uses P1, now THATS chubby xD
[Xperia Arc General] kiyu727:
Well compared to the Arc, it feels chubby in my opinion. Im very sensitive about that ;)
[Xperia Arc General] DaddyDan:
I've got 35% battery after 13 hours use. Thats texting, few phone calls, fb, twitter and a few games and wifi. I'm more than happy about that.
[Xperia Arc General] Gavilaaar:
I can't complain about battery life. I've had wifi on since I turned it on, data on, skype on, bin on fb and twitter, internet etc, played a few games and still battery is on 51%. Considering the phone is brand spanking new, I am very happy with it.

Btw, has anyone else noticed the stream of iphone apps now appearing on android. Back in the day when I had an Ipod touch, I had a game called Tap Tap Revenge. N you'll never guess what I just found :)
[Xperia Arc General] PollPixx:
Like the x10 it would take some time for the battery to work well, as the phone is quite busy in the background when you start using it for the first time. Give it a couple of days and report if your lifetime starts improving.
[Xperia Arc General] MJ_QaT:
I agree with everyone here.. even with P1i being chubby :p ( I miss those days :( )

as everyone said give it some time and it will improve a lot...

at first my battery lasted like 14 hours ( constant usage everything on, 3G, auto-syncing... you name it )

However, I tested my phone yesterday and found out that for the first two hours it lost 2 percent with just 10 minutes whatsapp chatting, everything on, GPS wifi... etc.... So its stand by is very good.... 9 hours chatting using whatsapp, browsing and checking XDA app and I still got 60% to go
[Xperia Arc General] Gavilaaar:
To be fair, that looks very promising.
[Xperia Arc General] Retrosid:
Did you charge the phone when you got it or you're waiting to get on 10% to re-charge it back to 100%?
[Xperia Arc General] Blomkungen:
there is no need to do that anymore....

And my battery life has improved alot

First day it lasted like 7 hours before I felt the need to jolt it up again

Saturday I got 15 hours

Yesterday I got 17 hours and still had 50% left, Had browsed alot that day, BT on, Blocket app

Some facebookchatting

Well moderate to heavy usage
[Xperia Arc General] wardy:
Looking at the Nexus S forums , seems latitude in maps is a culprit . I had it on all the time but now I've signed out my battery life is fantastic considering its not even into its first week
[Xperia Arc General] hnupek:
Blomkungen, how did you charge the phone on the first go ?

When you got the phone, did you charge it first ? Or you used stock battery and charged it after it went down? For how long ? thanks
[Xperia Arc General] im_iceman:
I've had similar experience with mine too.. got mine on Thursday and the battery didn't make it through the day.. yesterday it was draining at about 6% an hour.. so got about 16 hours out of it.. and today, so far.. 17% used in 5 hours.. and I've used it a fair bit this morning too..
[Xperia Arc General] SE-Naz:
I get 2days easily... Especially 3G is always on and PUSH email...

Very happy with the battery performance...
[Xperia Arc General] ronniecross:
I've spent most of today in bed, asleep, with tonsilitis.

At 7am I woke up to my phone's alarm. I then unplugged it, at 100%.

I phoned my manager to tell him I wouldn't be in work today.

at 1:30pm I woke up to see my battery was down to 31%.

So whilst I've been asleep for 6.5 hours my battery has gone down by 69% :-( I've had the phone since Thursday, so I'd expect based on other peoples stories of waiting a few days before the battery gets better for my phone to be ok by now, but it isnt :/
[Xperia Arc General] Rashkae:
That's not right... I left my phone unplugged last night at about midnight at 62%. It woke me up this morning at 8am and was at 57%.

I suspect you have some app in the background that's running.
[Xperia Arc General] Cim_XII:
My battery life is much better than with the X10.

only drained 5% in 11 hours of idle during the night.

And I've been able to get about 1-1,5 day of life with my normal use - compared to the X10 when I could get at most 1 day.
[Xperia Arc General] MJ_QaT:
nope, as soon as I got mine I turned it on and plugged it to charge, it was 56% already, so I kept playing with it till it reached 100%. Unplugged it and went out to enjoy my day.. used it a lot and for 12 hours of usage it went from 100 to 20%
[Xperia Arc General] tasgr86:
Mine arc drained 8%(from 33% to 25%) during night on flight mode.Too much for airplane mode ,and too low to have some app draining my battery.Any idea;
[Xperia Arc General] commodoor:
My first day with a full charge lest only 7 hours. And i'm certain it will get better.

But people who are saying that they have good battery, how do you use your phone?

3G uses more than wifi. so being connected to wifi instead of 3g would have 2~3x better battery. i know some people who don't have any data connection than the battery goes 1% per hour or two. Also if you have low 3G coverage try to use 2G mode only this would also improve the battery life, because 3G would always try to get the best connection and keep scanning.Screen also uses a lot of juice, so how many times is your screen on and at what percentage is the backlight.

The only thing that i want is better battery life than my NexusOne and this should be easy, i get minimum 12 hours and 16 hours max with my nexus (heavy usage). I use gtalk (total time: 1~2 hours), listen to music (45 min), gmail sync, tweetdeck (FB & Twitter every 30 min), whatsapp is on.

I will do little more battery testing with my Arc. right now i'm fully charging it en draining it again, and charging it again and counting how many times it's needs to get the best results.
[Xperia Arc General] NeidRider:
Similar story here; just lost 55%over night, autosync off, wlan off, bt off, just 3g... As there's no proper way of determining what drains the battery on the phone I just installed system panel app, maybe that will show something...
[Xperia Arc General] terroj:
I've had arc three days. During night with normal syncs etc battery dropped 6% in 8 hours. With active usage battery lasts about one day. With very heavy usage it lasts 8-10 hours.

I haven't had any normal usage so far but I think battery could last about two days with mild usage.
[Xperia Arc General] kiyu727:
The first time I didnt recharge my Arc overnight, now during my 9 hours sleep the battery fell from 95% to 55% which adds up to 40% drain in 9 hours while doing nothing.

I had wireless and Data turned off, used taskkiller after I set up my alarm so only a self starting app could be the reason for such drainage :( maybe I'll sleep with airplane mode next time -.-
[Xperia Arc General] olipheus:
I've read reviews from journalists that has the same problem as the OP. It has to be some kind of malfunction or something. Most users seems to have a great battery time.

Personally I managed to get 37h out of it, before it reached 10%, with moderate use. I didn't use it for music or film clips during this time tho, but I did surf alot, I have push in 2 e-mail accounts and FB + Twitter and I played games quite alot.

I've never had a smartphone with a battery time like that. I'm very impressed actually!
[Xperia Arc General] commodoor:
How long do you have your phone? i have almost the same setup as yours.

tommorow i will try to wipe everything and make a fresh start.
[Xperia Arc General] x9745:
Mine at night drop around 8%,( as a lot of people said) but charge up very good. Around one hour plus gets almost full bar!!
[Xperia Arc General] kiwi45:
After using ATK on aggressive setting my battery life has gone back to an acceptable level. It can easily lasts 2 days before requiring a charge. Not really sure which app is sapping the battery life though. :confused:
[Xperia Arc General] olipheus:
I got it 5 days ago.

I didn't charge it after unpacking it, just started it and drained it until it turned off, then charged it over night.

I've heard alot of people saying that the FB app drains a huge amount of battery. I havn't noticed that, but I don't use the app that much, so I'm not sure if it runs in the background all the time.

You might want to check that out.
[Xperia Arc General] commodoor:
I have my arc for 2,5 days now and the battery got a little better. fist day it was 10%+ per hour now i have 80% left in 3,5 hours, still not good but it's getting better. i also monitor everything an taking notes what i did and how long. so i will report back end of the day with all my statistics (also what i did and how i charged it)
[Xperia Arc General] im_iceman:
Mine seem to settle after 4 days.. standby seems to be draining at c.3-4% per hour and obviously active use is dependent on what I'm using..
[Xperia Arc General] commodoor:
So you can get max 24 hours and this if you don't do anything. what is your setup?

I'm still not impressed
[Xperia Arc General] im_iceman:
I don't think it's reasonable to expect any high end smart phone to give you much more than that.. If I didn't use the phone I'd probably get 2 days out of it..

set up wise.. using FB app - syncing hourly

using Gmail - push email

news and weather widget updating 6 hourly.

That's about it.. occasional task killing.. but not regularly at the moment as I'm not seeing any issues with it... old habits really!
[Xperia Arc General] commodoor:
No i know that battery life isn't good on smartphones. (not to sound like a fanboy) but the iphone can get better battery life than android phones. So the question is, is the hardware faulty or the OS?? btw i will never buy a iphone.

The only thing i want is that with average use to get trhough the day. and right now it looks impossible. 5,5 hours and used 40%, everage battery use is like 8% per hour, standby ~4% phone using ~14%.

I can start diabling all syncing etc but why do i want a high end smartphone if i don't gonna use the sync and push.

I think it's time to invest in battery life than in Hardware. to be honest a singlecore 1Ghz is more than enough for a phone.
[Xperia Arc General] MJ_QaT:
that's because iphones don't have real multi-tasking, once you switch off the screen almost everything sleeps. But android always applications to work whenever they want to, so it depends on programming and developers

My Xperia Play went 16 hours on idle and only lost 8%, 3G is on but don't use it, played for half an hour with Asphalt 6, and now after 20 hours I'm down to 83%
