[Android Q&A, Help & Troubleshooting] jacopoL:
I brought this second defective phone to the store and they gave me another GT-S5570 (different colour this time! :D).

On this third phone I did not install any of the apps I had installed on the previous ones and I didn't even put my SIM card in. I just configured a wi-fi connection and set the Wi-Fi sleep policy to Never.

Here we are again. I just found it like this: black screen, no response to keypresses, completely dead until I press the power button for 10 seconds.

Is the Samsung Galaxy Next/Mini GT-S5570 a broken phone? Am I missing something?
[Android Q&A, Help & Troubleshooting] juancollado2003:
Hi, if you have warranty just change your phone but I believe you are having problem with your OS I mean is a soft problem

[Android Q&A, Help & Troubleshooting] jacopoL:
I did it. I already changed three different GT-S5570s and they all had the same problem. They all had the stock OS.

I tried with two (very different) wi-fi access points. In the last phone I did not install any app.

are you successfully using the wi-fi connection always on for many hours?
[Android Q&A, Help & Troubleshooting] juancollado2003:
Yes I am I'm using emanon rom and I'm not having any problem
[Android Q&A, Help & Troubleshooting] skew4:
Jacopol, you made my day. My phone used to crash the same. I stopped setting the wifi-policy to "Never" and it does not crash any more! Thanks for a great workaround.

The ar6000/ar6k does not look reliable in Gingerbread Galaxy; you can find plenty of other people on the web complaining about it. I personally have experienced another problem with it: sometimes it just refuses to load. When trying to enable wifi the on-screen button turns green for a split second and then grey again. alogcat displays: "INFO: ar6000.ko failed to load" (yes, at the "INFO" level...)
[Android Q&A, Help & Troubleshooting] jacopoL:
It was incredible for me to find a hardware/driver problem like this in a production device from a quite big brand. I tested three different phones and they were all affected: no always-on wi-fi connection was possible.

I ended up asking for my money back and I bought another phone.
[Android Q&A, Help & Troubleshooting] skew4:
I unfortunately have to take some of that back. Thanks to this workaround it crashes... LESS OFTEN :(

It also seems to be highly environment/AP-dependent, roaming across APs making it worse.

I guess many people are not affected.

Looks like gingerbread fixed this... crossing fingers.

[T-Mobile Samsung Galaxy S II SGH-T989] 513263337:
The only problem is that this phone probably doesn't support HSPA 1700 band, so can't be used on T-Mobile, Mobilicity, Wind.

Althought it uses AWS, but that's LTE AWS, not HSPA AWS, not the same AWS that T-Mobile/Mobilicity/Wind uses.

as mentioned earlier it's the same Hercules design, just using a different radio

so, yes you can get it SIM unlocked
[T-Mobile Samsung Galaxy S II SGH-T989] 513263337:
My understanding is that this phone has:

GSM: quad band

WCDMA: 900, 1900, 2100, (no 1700)

LTE: 800 (AWS)

So it means it can't be used on T-Mobile. Am I right?

[G2 and Desire Z Q&A, Help & Troubleshooting] Keynot:
Hello,

well, I think I did a mistake... Yeah, my Desire Z (Germany) does not turn on anymore. Everything that happens is if the USB cable is inserted and then I insert the battery, the red LED turns on.

I tried starting it with power button, holding Vol Down, etc. But: the device is dead. No vibrating, no screen, no light.

The procedure was the following: I had DoubleShot before, but because the keyboard is creaking, I wanted to let it be repaired, so I wanted to set it back to defaults for warranty.

The standard ROM didn't want to load as PC10IMG.zip and CWM said that this file would be bad. I tried several original ROM's.

I had the flashed hboot for DoubleShot, so i thought, this could be the reason and tried to set hboot back.

I followed this guide:

http://xdaforums.com/showthread.php?t=999796

I dunno, I used the tutorial for the Desire Z, not G2. I had ENG S-OFF before, 100% sure.

The thing worked, so I tried to reboot.

Shut it down. Power on. Nothing happens.

Nice... I think this is a hard brick, isn't it?

Does anyone has an idea how to fix it? Only possible per JTAG and losing warranty?

Greets and thanks,

Keynot
[G2 and Desire Z Q&A, Help & Troubleshooting] Keynot:
Well I found a very annoying new thing.

If I hold Vol up+down, then plug in the USB cable, the Vision vibrates 3 times and the GREEN LED has now turned on!

Ehm, I think this is called the "Download mode". Is this unknown till now? I only found one member who has written that, no tutorial or similar.

Using Zadig, attached for Heimdall, I can now see my Desire Z as USB Device!!

It's called "Qualcomm CDMA Technologies MSM".

But.. I have the problem, that I cannot flash the Desire Z using Heimdall, because it cannot find compatible devices (well... it was programmed for Samsungs, so no wonder about it). Do you know any other programs that could do the trick?

The RUU doesn't detect the device neither. But I expected that too.

Any possibility now to flash a new hboot on the device?

Would be sooo nice!

Greetings,

Keynot
[G2 and Desire Z Q&A, Help & Troubleshooting] viper2097:
You can try it via fastboot if you still have the eng hboot on it and then flash the boot again, but when you cannot acces the device via fastboot or adb, i think you have a problem...
[G2 and Desire Z Q&A, Help & Troubleshooting] Nipqer:
The download mode is useless to us, you need to use a Qualcomm tool, with signed data, so we can't use that.

Sorry to say, but if you can't get to hboot anymore it seems you are fully bricked.

-Nipqer
[G2 and Desire Z Q&A, Help & Troubleshooting] Keynot:
Thank you for your answers.

I can't access HBoot or fastboot.

But isn't there any Qualcomm tool that lets me flash a new hboot on it?

And if not: I still have warranty, couldn't I send it back to HTC and let it be repaired? Can they see that it was my fault?

Thanks,

Keynot
[G2 and Desire Z Q&A, Help & Troubleshooting] Nipqer:
There is a Qualcomm tool, but as I said its useless to us because we need certain keys.

Your best bet is to send it in to htc, it should still be covered.

[Atrix 4G Android Development] jasonwalker1980:
YES.. AFTER UNLOCKING AN ATRIX YOU CAN NOW MAKE IT WHERE IT WILL NOT SHOW UNLOCKED ON BOOTUP.... Instructions below...

After receiving my warranty phone I was desperate to make it not show the unlocked symbol where they would see it.. so what I did is research first.. I had remembered a team called M3 here while back make a bunch of unlocked stock SBF files. I specifically downloaded the newest Gingerbread SBF file. I then rooted and flashed Alien #4 on it as well. Well need to say the least my digitizer went out. Don't really know how that worked but anyways I called AT&T and got it under warranty then I realized OH SH*% I have it unlocked. so what I did is I went and grabbed a STOCK NON UNLOCKED SBF GINGERBREAD file and flashed it. THEN WALLLA it was gone and back to stock.. NOW HOW DID THIS WORK? How did it bypass the fuse from the boot loader WHY did it not brick the phone.. My thinking's is that it is still unlocked but just using a locked boot loader software. hmm maybe someone here can find that out.. I was just doing anything I could to make it not show that symbol so needless to say I was a brave mother F'er So I would be COMPLETELY enthused to how this worked and how it still loaded the phone..
[Atrix 4G Android Development] g33k3r:
Umm, this information has already been known. Also, you shouldnt be using SBF anymore.
[Atrix 4G Android Development] jasonwalker1980:

[Atrix 4G Android Development] roughriduz:
I have seen this same thing happen before while just using an sbf on my phone,but the unlocked symbol usually came back after the next restart... I would restart a couple times before getting too excited
[Atrix 4G Android Development] Sinful Animosity:
You can use SBF's. It's just not recommended anymore.

[HTC Wildfire S] playagiron:
Apparently, the battery life and the low internal memory are some major drawbacks of this otherwise great handset, so I though of putting up some experiences of what users report from their experiences with internal memory and battery life.

(After installing all programs and under normal usage)

ROM:

System 260MB => 32MB free

Data: 150MB =>32.7 free

Strategy: rooted, uninstalled htc stuff.

Battery Life:

24-36 hours

Remarks:

I feel the battery behaves rather strange, think there is definitively room for improvement. Some days, it hardly uses 5% over 12 hours!! Then, on others, without touching it, it looses over 50%!!

I am currently playing around with the Network settings and will see what I find.

Underclocking on demand should further alleviate the problem I hope!

With the original WF I easily got 4-5 days and the battery is only marginally smaller so should be possible to get closer to this range
[HTC Wildfire S] Henry_1:
Here my results:

About 50 MB free of ROM.

About 100 MB free of RAM.

Stock ROM, S-ON (waiting for htc unlock and cyanogenmod:D)

Battery lasts under normal usage 2 days, light usage 3 days. (When i sleep phone is in fly mode and there's no battery drain)

Normal usage: little browsing, messaging, mailing, music listening, checking news and weather, maybe a phone call.

Light usage: messaging, mailing, a bit music listening, calendar checking, very very little browsing

The biggest battery drain is the screen, especially when playing games (15 minutes dragon fly gives 10 % battery drain) and browsing, market checking/updating.
[HTC Wildfire S] ZeDWeB:
Everything stock:

free ROM: 47

free RAM: 122

Around 2 days battery use if I don't play too much Airport Mania 2, or else 10 minutes play equals minus 5% battery
[HTC Wildfire S] playagiron:
UPDATE:

I changed some settings to maximize battery performance, notable

Location => Disable "Use Wireless Networks" (battery eater!!)

Wifi&Networks: Mobile Network Settings:

Network Mode: GSM only (OK I don'T need the fast one)

Enable Always-On: DISABLED

Plus I set it on Flight Mode during night (I used Gentle Alarm to do it before, but apparently there is a bug where it makes it consume engergy nevertheless so do it manually now for the moment)

Results:

For now, 3-4 days!

Will continue trying out (but now it will take a week or two to finish some cycles ;-) )
[HTC Wildfire S] hypercode:

[HTC Wildfire S] CitizenLee:
Sure you can kill 3G, WiFi etc but then why have smartphone and dumb it down?

Here are a few battery saving tips I've learned from owning a GSM Hero and Desire HD (my gf has WFS which is why I'm lurking here... just ordered a XTC Clip for it).

Unfortunately when the green light says you're phone is fully charged this isn't always the case. The battery is likely to be mis-reporting its capacity and % used, this can cause your phone to die when the battery still has remaining charge. So, we're going to fix that.

Assuming you have already rooted your phone, download Battery Calibration tool and CurrentWidget.

Place a CurrentWidget widget on your home screen and charge your phone until the widget says 0mA. This means it has reached fully capacity.

Once it hits 0mA on the widget, open Battery Calibration and wipe battery stats.

Reboot your phone whilst still plugged in and upon reboot it will recreate a new battery stats file, however now it will know the battery's max capacity and will correctly report battery % used.

I do this about twice a week. Maybe once a month I will also let it completely die and then fully recharge whilst off, before powering on and repeating the above steps.

Other things you can do to increase battery life are:

Change the sync interval of apps like Facebook, Weather etc. I usually set most things to every 3 or 4 hours, with Flickr only being once a day.

Don't run the screen at full brightness if you don't need it. On my DHD I find 40% to be best for most conditions, with only really bright sun making it hard to read... in which case I bump it up to around 75%. Auto-brightness if ok but it tends to be on the bright side on most Sense ROMs so hopefully someone will work out a way to tweak the values for WFS. I had a play about with custom values on DHD but after testing for a while I still prefer to control it manually. It's a personal thing though.

Remove crap you don't need. Stocks, News, eReader, Twitter etc are always the first to go when I install a new ROM. I use Root Explorer to delete them but there are various ways to do this including Titanium Back-up or by using ADB. You can find everything in /data/app & /system/app. Just be sure to do a nandroid backup in case you delete any system critical apks.

Change Wifi sleep policy to Never.

Limit your homescreen widgets to only ones you really need. Having 7 screens packed with widgets and apps will cause battery drain.

Turn off Power Saving mode. I tend to find it doesn't really help and just makes your phone quite useless when you hit the pre-set % where it activates.

Never use Task Killers. This link gives an excellent explanation.

Finally, wait in hope for an overclocked and undervolted kernel, different radios and custom auto-brightness values ;)

If I can think of anything else I'll post it here ;)
[HTC Wildfire S] methadron:
don´t know why so mutch people get worried about the battery. for me the only thing that counts is that the battry takes me over the day. i mean i go out an seven am and get bat at 5pm, so thats the time i need my battery to hold. maybe i need some backup to get until 22 pm and everything is alright.

for me i doesnt matter if i´ve to recarge after one day
[HTC Wildfire S] CitizenLee:
Yeah, for some people it can become a bit of an obsession. However, it still think it's worth taking a few simple steps to get the best out of your device ;)
[HTC Wildfire S] thehumble1:
For some people 8 hours between charges is fine. For me, I like a phone that can run for 8 hours between charges, but also run for 48 hours between charges (without having to go to dead mode by turning on airplane). I go camping, stay the night someplace else, forget my charger while going on a trip or just want the freedom of not having to find an outlet and drag my charger with me if I want to have a phone run for more than 8 hours. So I get off work, change my clothing and run out the door to my after-work sporting event, then head out for a few beers afterwards with the team and I barely have enough juice left to call my wife or check on a few game scores.

It's important. Not having it be important means your phone is running your life or you just always have the same routine, which is fine for you maybe but I like to head out.

I dont know why, but cyanogen, and sense roms, still sloow and unresponsive, compared to the Optimus 3D, the optimus 3D its super fast and fluid...

Someone can tell me why?...

And better dont set the HTC Sensation at 1Ghz, still slower than at 1.5Ghz...

My old HTC HD2 stills smoother...
[HTC Sensation] moshe22:
I think is because of the way the processors are setup. They don't seem to be optimize 100% possibly because is a new way of building phones. Two cores instead of one and that might make it harder to optimize and build drivers.

However on the latest ruu with sense 3.5 people are reporting that everything seems smoother.
[HTC Sensation] |ErosizeD|:
Optimus 3D stills on 2.2 Froyo, and runs super fast... i mean, the sensation runs good, but isnt fluid at all, and not as fast as the O3D, and other devices. ( SGSII, O2X...etc )

And this CPU is suposed to be the best of all those CPU outhere, because its the most powerfull of adreno, and runs by default at 1.5Ghz, consuming small amount of power.

[HTC Sensation] moshe22:
I concur with you because I had the G2x which flew through everything, sadly it didn't work the way it is suppose to most of the time even after update and LG support is horrible, no communication with their customers whatsover, which is what made ne switch to the Sensation. Even though the Sensation is not as fluid I really much enjoy it much more than my G2x.

So I'm not sure what is it that makes this phone stutter.
