  1. voyteckst has the patience of a saint. Those two questions have been discussed several times in this thread and also have their own threads in this sub forum. How hard is it to use the search box on the right? -----------------------------------> You know, the one that says "Search" with a pulldown box for options for "This Topic/This Forum". Try it - just type one single word in there. It really works, you lazy bastiches.
  2. Someone posted in an earlier message (on this thread) that it was taking 2 minutes and 50 odd seconds to start CM6 Beta 1 from Haret to Lock Screen. Just for comparison, I get 1 minute and 35 seconds (class 6 SD card install) from clicking on Haret until the Lock Screen is first seen. Regarding the camera, add me to the list of people for who it doesn't work (I get Forced Close). When I first installed clean, it was working (button did not work, but the camera could be started from shortcut, or gallery). Now that I have installed additional apps (nothing unusual; angry birds, gmail and a couple of other things) it no longer works. The device can see the SD card and the Internal Storage OK. I might have to try uninstalling stuff again and see if the situation changes, otherwise I'm not sure what could have made it stop working. Good job on CM6b1 devs. Thanks.
  3. Yes, yes, yes. I have been programming for over 35 years and I started in 8080 machine code, without even an assembler. But you missed my point. How does this change the real world result of the benchmark? Answer, it doesn't. It takes the time it takes. Yes, agreed; parallel transfers are faster than serial (I think I agreed with this on my last post), but the magnitude of the time difference between the transfer of the data and the access (actually getting, or putting, the data word from the memory array) makes the transfer time insignificant. For example, if it takes 1 second to transfer some data serially, 0.1 seconds to transfer in parallel and 100 seconds to access, then it is 101.0 seconds versus 100.1 seconds. The difference is neglible. No I am not confirming that (and I did not do so in may last post), but see above as to why it does not lead to your conclusion. And this is what my benchmark demonstrated; that the access time of higher speed SDHC flash memory cards is less than that of the internal flash memory. Less access time = faster access, since the transfer time is neglible in this situation. Anyway, I feel we are going a little off-topic here, so if you want to continue the discussion please PM me ;)
  4. Or maybe leave the guy alone to work (or even have some time off)? :P He already knows about all this stuff and the stuff where "almost everything is working" but isn't; like the front cam, the FM radio, the other bugs people have already reported (some can't get normal camera working at all, slow gps fix, etc.) ... and I am especially sure he knows about battery life - in fact I know he does, since he said (a few pages back) that he was already working on an issue related to it and the magnetic sensor ;) Besides, Winter is coming and it is good to be able to use the O2 as a hand warmer :D
  5. You are assuming I didn't do my homework :P I looked at some technical documents on the S3C6410 (ARM11) chip beforehand, as well as some other datasheets. What you say is true, to an extent. The internal DRAM, NAND ROM and Flash memory do have parallel paths, whereas the external (SD) flash memory has a serial one. All memory access paths have a related memory controller together with associated overheads (part of the reason as to why the processor needs cache DRAM). However, the limiting factor here, in both cases, is the actual speed of reading and writing flash memory at the memory chip level, since (if you look at the specs for current technologies) flash memory access is still relatively slow compared with accessing say DRAM. Transferring the data is a relatively small part of the total access time. The 2GB/4GB/16GB "internal" storage (My Storage in WinMo) is definitely flash memory (and 3 year old memory tech at that). I'm not sure why you deemed my simple benchmark as too "high-level", since it uses pretty much all the same mechanisms that the operating system would use to, say, write to the swap file. The relative results aren't going to change much irrespective of the underlying hardware implementation. The first test to the SD card is still going to run faster than the second test to the "internal" storage, however much you talk it down :D Of course, to be fair, the read test (which I didn't post) is much closer and there is the fact that internal storage probably uses (I do not know for sure) less juice.Given the rate at which the battery runs down, it would be useful to test internal versus external (using small and large capacity cards) to see if there is a dramatic effect on battery life.
  6. Yes, that was my point and why I posted the simple benchmark. It is worth noting that class 6 SDHC cards must be able to sustain a write transfer speed of 6 MB/s and in practice, all the different makes that I have tested are at least 10% faster (some more). Class 10 SDHC cards, iirc, must also meet the minimum of 6 MB/s sustained write transfer speed during random access, but they must also achieve 10 MB/s during sequential writes. So class 10 is not quite as big a jump as it might seem, from class 6.
  7. As said in an earlier post, GPS is a lot slower (to acquire a fix) because they are not using the native mode phone access like in beta 2. they said they are working on it. Mine always charged to 100% with beta2 and beta3. Maybe it is related to the condition of your li-ion battery. What does it say in WinMo? Earlier in this thread someone posted an alternative Calibrator.apk which solved the same problem under beta2. I downloaded the HTCCalibrator.apk file (google for it) which is better because it uses offset points around the screen and not points that are right at the edge and that you can't actually hit. No they won't. See what I did? It is not faster than a even class 6 SD card and unlike you, I will provide you with my proof. People need to question things they read on the internet and not just accept them. Thinking for yourself is a good thing. If you can show me proof to support your statement, you might convince me, otherwise ... First run of DD (below) is writing to a class 6 Micro-SDHC card, second run is to the internal storage: # cd /sdcard # dd if=/dev/zero of=test.empty bs=1024 count=500000 500000+0 records in 500000+0 records out 512000000 bytes (488.3MB) copied, 67.996479 seconds, 7.2MB/s # cd /storage # dd if=/dev/zero of=test.empty bs=1024 count=500000 500000+0 records in 500000+0 records out 512000000 bytes (488.3MB) copied, 80.422052 seconds, 6.1MB/s
  8. Why? It's crazy to risk internal storage rather than a decent SD card. I would say SD card install is easier,faster and safer until one day we can get a NAND ROM stable release. Besides, a lot of people have internal storage used with WinMo related stuff and are still using WinMo. o2droid is still beta.
  9. I checked the differences as well when I first saw the post and I agree that what voyteckst says is correct. I am of the opinion that you should always double-check what people suggest, since circumstances may have changed, or not apply in your particular case and it is better to make a more informed decision as to whether to apply a change than to just do it parrot fashion. From what I have read on the subject, it seems that INTERMEDIATE_POS=1 will give you a quicker fix, but not necessarily a very accurate one. It will still take as long as it takes with INTERMEDIATE_POS=0 to get the same accuracy. Still, for some it may be better to get a rough fix, faster, than no fix at all for longer.
  10. What is the obsession with My Storage installs? Ok, maybe if you don't have an SD card (Why not? They are so cheap now), or if the SD card you have is as old as the hills, but class 4 SD cards have been around for ages and you can buy class 10 SD cards really cheap nowadays. IMO, a class 4 or better SD card is as fast as My Storage and it has the big advantage that you can easily replace it. If I'm not mistaken (maybe I am), "My Storage" is NAND ROM flash and that has a useful lifetime of 100,000 writes (could be as little as 10,000 if earlier technology). So if you put a swap file on there and perform 1,000 writes a day; your My Storage is going to last less than 4 months before pages start going bad. Well, maybe I am mistaken, but I'm not going to take the chance personally.
  11. If you're worried about beta3 not being quite ready for prime-time, or simply want to install beta 2, but you haven't yet been able to because you need some more detailed step-by-step instructions, then you may find this post useful. If not, or you're messing with beta3, then move right along please :P I used these steps to install Froyo beta 2 (and then reinstall it several times): Assumes: Samsung Omnia 2 GT-i8000SD Card with primary FAT32 partition (optionally ext4 partition of previous install as second partition)\My Storage is as per factory configuration (i.e. unmodified) End Result: WinMo (in ROM) untouchedSD Card FAT32 partition shrunk to SD Card size - 1GB (Make sure you have the free space and maybe defrag or wipe FAT32 partition)\My Storage is as per factory configuration (i.e. unmodified) Remove Previous install: Connect phone via USB to Windows PCOn PC browse to \Storage CardDelete Folders: .android_secure, AndroidDelete Files: ext4.tar.gz, haret.exe, o2b2update.tar.gz, o2b3update.tar.gz, startup.txt, zImageDelete Folder: 02betaOn PC browse to \My StorageDelete any of the files specified in step 4 that may be there on \My StorageDelete o2beta folder on \My Storage if found Prepare for install: Download Froyo beta 2 manual install from http://87.229.73.80/...manual_inst.zip to your PCExtract single file ext4.tar.gz (154,357,856 bytes) from zip in step 1 to a tmp folder on PCDownload Froyo 2 beta auto installer from http://o2droid.phj.h...2_auto_inst.zip to your PCExtract all files from zip in step 3 to tmp folder on PCSearch for and download o2b2update.tar.gz (460,140 bytes) and o2b3update.tar.gz (1,670,874 bytes)Copy/Move two files in step 5 to the same tmp folder on PC as in step 2.Check tmp folder on PC has the following files and sizes: o2beta <DIR> ext4.tar.gz .............. 154,357,856 haret.exe ................ 182,272 o2b2update.tar.gz .. 460,140 o2b3update.tar.gz .. 1,670,874 README.txt ........... 510 zImage ................... 2,505,044 6 File(s) 159,176,696 bytesCheck tmp\o2beta dir (on PC) has the following files and sizes: androidinstall.exe .... 193,024 sd.cpio.gz ................ 8,672,084 startup.txt ................ 184 zImage .................... 2,464,452 4 File(s) 11,329,744 bytes Install: Copy contents of tmp folder on PC (from previous steps) to phone's \My Storage (151MB Free space needed)Using phone File Explorer, navigate to \My Storage\o2beta\ and run (double click) androidInstall You will see a "haret Booting Linux" popup with a timer bar, then a black and white screen with very small writing, then after about 30 seconds scrolling Linux startup text messages. You might notice the following: "mounting internal SD memory as mmcblk1p5" and "cannot bind tcp:5037", then: "... Done. Rebooting now ...." You might also see "Kernel panic - not syncing ..." and "Rebooting in 30 seconds..". You may hear a crackle from the phone's speaker, then the Samsung boot screens will appear, followed by the WinMo boot screens.Wait for WinMo to come up, then open File Explorer and navigate to \My StorageDouble-click haret You will see "Haret boot ..." text, then 30 secs later a pink screen. After 30 secs into pink screen you will see USB device recognised by windows if the phone is still connected to the PC. Approximately 1 minute later the pink screen will disappear and the "android" logo screen with the "cylon-like" effect appears. Approximately 3 to 4 minutes later the phone may vibrate slightly, then approximately 30 seconds later the android PIN screen should appear.You can now delete o2beta directory, ext4.tar.gz, o2b2update.tar.gz and o2b3update.tar.gz from \My Storage. Note: Check file sizes (in bytes), on Windows PC, with property page size: value or using command window and dir command. The above are the steps that worked for me. The only thing I'm uncertain off is whether both o2b2update and o2b3update files are needed. I looked inside them and they look like they address two separate issues that are pertinent, so I used them both.
  12. I agree with this sentiment. If you think it's slow, stop trying to run stupid live wallpapers and every shiny piece of crap and apps (:D) on your home screens and concentrate on what is important - phone, contact, messaging, browsing and GPS performance. Being able to play around with other Android stuff is just that and a bonus. If you want the shinies then it looks like you're going to have to pony up the dosh for a new phone. We can also wait and see what beta3 brings. I expect it will be better, but it is still unrealistic to expect the same from our Omnia2s as a Galaxy S2. I think this is a great project because it lets us mess about with Android to see how we can get the same things (functionality) out of it that we have on WinMo and decide on whether to spend the money on an up-to-date Android phone, or not. I think I will even be able to use it to give my O2 to my wife (she only wants to make calls and send messages) with a little more customisation than I could perhaps get from WinMo thus allowing me to buy a new phone for myself without getting a lecture on spending all that money on a new toy :D
  13. I would like to know the answer to this question as well. Also do people notice a worthwhile speed difference using a class 10 (10 MB/s) SD card versus say a class 6 (6 MB/s) SD card, or does the O2 phone SD card hardware/processor bottleneck after a certain transfer speed?I noticed that class 10 32 GB Micro SDHC cards are cheaper (than they were last time I checked) these days.
  14. I have the same problem too. USB works for a while, then stops being recognised. I have to reboot (Vista 64). Rebooting the phone does not fix it - so I'm not sure how much is a problem with Windows versus a problem with o2droid. Using WinMo it does work fine all the time, though.
