What's the budget? There are a bunch of xperias with ics (some even upgradable to jb).
[Android Q&A, Help & Troubleshooting] xudsa II USERT:
There are plenty cheap stock ICS phones, built by LG and Samsung, such as the Galaxy Ace. Look around for the best value for money.
[Android Q&A, Help & Troubleshooting] mdfzhi:
lulz. bad advice. the galaxy ace came default with froyo, upgradeable to gingerbread, but if anyone buys it now it'll came default with gingerbread.

but definitely not came default with ics and not upgradeable to it either, officially.

i own one previously.

imho ace is not what op is looking for. by todays standard, amv6 phone is a big no-no.

[Android Apps and Games] thepenguin77:
I've held out on posting this app here for 6 months so that I could make sure I give you guys the best app possible. Here's the market description, and enjoy.

The first legitimate strobe light / stroboscope app for Android. This app allows you to flash your flashlight or your screen at whatever frequency you choose.

Features include:

- Flashing frequency adjustable from .05Hz to 100Hz in .05Hz increments

- Adjustable duty cycle (ON/OFF proportion)

- Optional RPM units as well as multiplier

- Torch mode

- Continues to flash even if screen is off

- Adjustments specifically for use as as stroboscope

- Burst mode

- Adjustable screen flash colors

I made this app after searching the market for a strobe light that I could fine tune. Most of the other apps either only flash the screen or simply give a slider that changes the flashing frequency in an unknown fashion. This app allows very precise control over the strobe light and is accurate enough to approximate the RPMs of a spinning fan or a turntable just like a stroboscope. You can even slow the strobe low enough to use this as a blinker for your bike at night.

One of the best parts of this app though is that you can change the duty cycle of the flash so that the flash will be turned on for, say, 10% of the cycle rather than 50% of the cycle. While this may seem trivial, at a strobe frequency of 4Hz, 50% is simply a light flashing ON/OFF while 10% is a strobe providing quick bursts of light.

Give it a try! It's a high quality strobe light and is way more fun than using a flash light.

A quick note about different phone hardware:

This app works flawlessly on some phones and pitifully on others. Before you say "this app is crap" send me an email and I'll see if I can get it working on your phone.

Updates:

v1.1.2

- Improved strobe consistency

- Improved strobe timing

- Added burst mode

- Added adjustments for better stroboscope operation

- Added x2 and x½ buttons

- Added lag detection

Best strobe app.

You can control just about everything. It is the most detailed app and it's free. This is how other strobe apps should be.

- Improved strobe consistency

- Improved strobe timing

- Added burst mode

- Added adjustments for better stroboscope operation

- Added x2 and x½ buttons

- Added lag detection

This update actually greatly improves the quality of the strobe light. I did a lot of tweaking with the LED and now my phone can consistently put out 3 ms flashes.

This update fixes a lot of problems there used to be. I can't find anything wrong with this version.
[Android Apps and Games] asim.sidz:
Hey

Hi,

i've tried your app and it works fine. Does exactly what it is meant to do. What i'm looking for is to adjust my flash's intensity while i'm capturing photos/videos with the camera. I know that it is very much possible but i've no idea about how to go around that myself. I'm okay even if i could permanantly change the value of the maximum ( Or maximum threshold value) brightness to some other lower value.

Any kind of help or guidance regarding this will be highly appreciated.

P.S. You can make another app out of this and put it on the Play Store.

As per thread title, I want to buy a replacement of the vibration motor for the GSM Galaxy Nexus because mine started making weird noises then it simply dies out. After disassembling the phone, I took out the motor and it made rattling noises when I shake it.

Can anyone recommend some good places to find one? I've looked at Rounded and Stellatech but I'd like some more alternatives.

Thanks in advance.
[Kindle Fire Q&A, Help & Troubleshooting] Arananthi:
Everything was finally just like I wanted it on my rooted Kindle -- had Google Store running just fine, loved it. Then along comes an update pushed out by Amazon that unroots my Kindle. Now about once every 5-20 minutes it pops up with "Application Vending stopped unexpectedly." Whatever; I re-rooted it no problem (Thanks KFU!), reinstalled GoogleServicesFramework.apk and Vending.apk -- but the Google Store ('Vending') still force-closes every time I open it and occasionally at random.

Any ideas on how to get Vending to work properly again?

Thanks!!

aluminum frame with flip.

i haven't seen this here yet so i thought i'd do the combination myself.

aluminum frame with oem flip, frame locks with slide which is tight with flip in grooves.

CONS

no all the way flip.

have to take out of bumper to change battery.

this http://www.ebay.com/itm/Metal-Aluminum-Frame-Bumper-Case-Cover-For-Samsung-Galaxy-Note-2-II-N7100-Silver-/281022281700?pt=PDA_Accessories&hash=item416e3bb7e4

with a flip

frame has good cut grooves for grip. ultra thin.

(i took these photos with my gn2)
[Galaxy Note II Accessories] twe90kid:
Can you comment more on the alu bumper?

I like to know how's the quality, fitment... Sturdy? Worth the price?
[Galaxy Note II Accessories] ilandboi14:
The fit is very snug, I was worried about the back of the flip battey cover since it is thicker than the original but good fit and I may try an extended battery when that arrives.

The quality is top notch for 18 usd the frame has minute details of how it was once a solid block. And it has this coating which I think really helps to prevent oxidation and it gives the metal a more soft feel.

One con I noticed was that I have a snug fit aux plug but it works.

[Galaxy Note II Accessories] Jim Dead:
Anyone know of a bumper case that bolts together for the Note 2 (I have one for my Note 1)?

I have had a the 2 part slide together frame on my Note 1 but when I dropped the phone, the frame would pop off. Also there was some movement which caused a corner of the phones chrome frame to rub off. Because of my experience, I would recommend some foam tape in all 4 corners to prevent this on the Note 2 with these frames.

[Sprint Samsung Galaxy Note II] wittmannj:
i think im out of luck here and this is the first time this has happened to me. i recently rooted my note 2 using the toolkit that was in the thread for all variants. i used the mack rom with the perseus kernel. then i recently read that they recommend updating the kernel. i downloaded the kernel and for got about clearing the cache and dalvic cache before flashing. i rebooted and now stuck in bootloop with no backup. i just want to get it to work again but i got a bad feeling that there is nothing i can do about this since i can get anything to my internal memory. twrp is my recovery and they dont mount the sd card yet. any suggestions?
[Sprint Samsung Galaxy Note II] kingdazy:
I might suggest holding vol-down/home/power together while b-looping, see if you could get into DL mode, flash something in odin to get back to stock at least, start over. or try to see if that will work with recovery, reflash the kern. but you may be SOL on your current data.

and there's always batt pulling before trying to get to recovery/DL mode, but i try to avoid it when possible. but sometimes that's all ya get. ;)

[Galaxy Note II General] watsa:
It is for india too. There is no branding here
[Galaxy Note II General] victorator:
If you look at the 2nd segment of the filename, in this case - N7100OXADLL4

This signifies the CSC, which in this case is for a couple countries (multi csc) and means it's unbranded. If you would have a branded rom like the last Play rom for example, the 2nd segment was N7100PRTDLK5, and it meant that this was solely for the polish operator Play.

OXA is unbranded. OXX also. If you see firmwares for a couple countries using the same code, it means it is unbranded.
[Galaxy Note II General] DanDroidian:

Will I lose my root privileges ??
[Galaxy Note II General] victorator:
Answers:

No, you don't need to do anything after you flash this, even if you have a different csc, nothing bad will happen. It's just for Kies app compatibility reasons.

Yes, you need Odin to flash this firmware (standard procedure, select the .tar file for the PDA section).

No, the exynos mem bug is far from being fixed (just rooted my phone with exynosabuse).

For the modem you need to extract it first and flash it with odin (needs root + some console command knowledge, not advisable for newbies until someone creates a cwm update package)
