Yes, it's like your PC. Basically, if the virtual memory is use more, then you phone will start to face some performance issue.

Sometimes, some process might have "hang" and hogging the processor or ram, best is to install the "System Info Widget" which allows you to monitor the processor and ram usage in percentage in your Desktop. You can also use "Conky" to view in details. If you know how you can manually kill the process or use HTOP app. Basically if you're using Windows, it's like killing monitoring and killing processes in the Task Manager (CTRL+ALT+DEL).

For easier way, just restart the phone.

Added on May 7, 2010, 12:14 pmThe DC-11 description/manual mentioned it can only fully charge a 900mah battery. So, it cannot fully charge the N900.

Source from the web mentioned that the DC-11 is packed with a 1500mah battery.

MY personal advice: Try NOT to drain the DC-11 battery completely. Let's say you know the DC-11 took about 2 hours before it run out of battery, try to stop using it earlier. It should be a Li-Ion or Li-Poly battery, so it's safer not to drain it completely, altough I think it should have some prevention in place (e.g. will not charge if the battery is below say 10%?). Just my personal advice to be safe.

There is reason:
1. Still under testing
2. Claimed by some that the leaked version is old, there is already updates. However there's no source to back it up.
The HK firmware seems to be same version as the leaked version.
3. Some sites mentioned Nokia claims it may cause damage to the N900; not exactly sure how? Probably it mean data damage. But not sure if it's official Nokia statement, and if true, what about HK version?
4. Some owners claims after updating, there's problems with Conversations, not sure what happen to theirs; Mine is doing fine, or even better? Still can apply the customization as before.

Anyway, for anyone who cannot wait anymore, make sure you backup your data, and make sure the firmware source is from reliable source that those flash have no problems with that source.

Overall, current leaked PR1.2 isn't what expected and is disappointing, feels like minor updates instead. Hope the actual official will be a lot different. I mean, there's still sooo many things to be improved on the N900....

Recent interview from Nokia CEO posted in maemo-talk, it's even more disappointing; Seems there's still no plans to include contacts grouping, individual ringtone assignment and all those common phone functionality....

Added on May 7, 2010, 4:29 pmIs it really from Nokia? Or someone impersonate as Nokia? As I know from maemo-talk, some of the members are anti or against this leaked PR1.2

The HK N900 already release with PR1.2, as previous picture posted, it's the same version as the leaked. So, if there's really problem, why Nokia release in HK? I have no idea
Funny HK gets PR1.2 first, this is same scenario with Motorola Milestone... HK gets Android 2.1 first hand... while others have to wait weeks... Will this PR1.2 suffer the same?

Even for this leaked PR1.2, the built-in Facebook Chat plugin recently receives updates.

I've mentioned before, it's better to install the "System Info Widget". Sometimes, some processes may "hang" and hogging your CPU resources to 100% usage. Your battery will be drain in no time. I've experience few times, usually it's the browser, have to manually kill it X-Terminal or HTOP app.
The easier way would be restart your phone.

Turning on Wi-Fi shouldn't drain your battery so fast, even on GSM mode (2G/2.5G). With Wi-Fi, I have no problems connecting it whole day, with GSM (2G/2.5G) mode, from morning around 9am till afternoon around 3-4pm, still got about 40%~50% depending on usage.


Actually, even before the lower voltage is used, OC have also claimed to have better battery life.
I believe it depends on situation, if using at 100% for long time, surely OC will consume more battery life. But for normal usage, OC actually might give better battery life.
If you notice, once we go online with the N900, the processor will use up to 100% for a few seconds, mainly because of connecting to the accounts (skype, etc). Now, with OC, with the extra processing power, it might use less time to complete similar task, thus possibility of consuming less power. Some goes for other processes. Most probably that's why many previous OC without ULV claims to have better battery life than stock.

Install "HTOP", this app is pretty easy to use, just see which process is running at 100% all the time or high processor usage, select the process ( by touching or use the keyboard arrow keys), there's option at the bottom u can select an choose kill.
Make sure you know what you're using, some process are system process like hildon-desktop, etc. usually what I encounter is browserd hongging the processes, even tough I have no browser running.

The simple way is to restart the phone, if you aren't sure.

Yes, the leaked PR1.2 data counter has some changes, it added roaming counter, thus the current Personal Dataplan Monitor widget will not work.

Might need to wait for official update so the author of the program will update it.

For now, you can view it via Settings manually or if you know the "command", you can use "Desktop Execution Command" widget to do it.

Slide your finger/stylus from OUTSIDE the viewing/display area towards or into to display area, a cursor will appear. (There's space where there is no display).

For more information, see the below video (last part):

I tested this and it works in the leaked PR1.2.

Currently need to activate it everytime, possibly in the final version it will provide it as an option, like the web browser.
Problem:
1. Viewing contacts sms/conversations, the alignment seems not aligned properly. The avatar at the bottom, not in-line with the message.
2. When touch on the input textbox, on screen keyboard activate, but it is Landscape on-screen keyboard.

Anyway, great to see they're planning to do one official vertical SMS now.

As for the Media Player orientation, personally, I feel it doesn't look nice in Portrait mode due to the design. Based on the designed, it should be in Landscape mode. For Portrait mode, porbably they need to show 2 rows, with 2 icons each... or probably they need to change the design.... I like the current lanscape design, hope they won't change it...

This is the beauty and advantages of resistive touch screen, the ability to use stylus!
Even the original sketch app is very good! Choose fine pencil and you can do nice sketching.
Only problem is the display area and cannot rest your other part of your hand on the screen, else it'll messed up your drawing because it actually sort of "supports" multi-touch.

With whatever touch screen phones, it'll be harder to sms compared to normal phones with keypad, mainly because you cannot feel or know if you have press successully without looking at the screen. With phones with keypad, I can sms while walking and looking at the road, even at busy shopping malls, there's no need to look at the screen because you know if the key is successfully pressed and so on. So, I just need to glance at it once in a while or read it at the end, etc.

With touchscreen, it'll be a problem even on normal texting, you need to really see/look, else you'll do much more mistake, more so if it's qwerty on screen with is smaller buttons. And for sensitive touch screen, it'll be more problematic because you'll easily accidentally hit a few words, and worst, for those phones without arrow keys for your to move the cursor around.

If truly want to SMS, just get another cheap phone for texting mainly, lol

Ya, but what I mean is it can never beat the good 'ol keypad.

Besides, the biggest problem is there's no FEEL whether you have press the key, so if you don't look, you can't be sure. For not sensitive keys, you might face problem not pressing the key although you have press it.
For too sensitive keys, you might accidentally pressed a few keys.
For balance in sensitivity, there might be less problem, but still you're not sure unless you look at it.

So, you might need to look at the screen more often compared to good ol' keypad which you can even NEVER look at it and be quite sure you make no mistake.


Plus, if it's on-screen keyboard is qwerty, it pose another problem due to the buttons are smaller and close to each other, hardly anyone can touch correctly without seeing the screen.
Q W E R T Y
Imagine hitting the button correctly without seeing, and this is only 6 buttons, actual "on-screen" qwerty keyboard is different, and also depends on the screen size and so on.

For numpad version of onscreen keyboard, it's far easier as there's only 3 buttons in a row. But still, there's no feel whether you have successfully press the button, unless you turn on LOUD volume for button press and possibly vibrations to help you feel more.

Nonetheless, for on-screen or virtual keypad/keyboard, it'll definitely interrupt the person more and requires more checking compared to good 'ol keypad.

What video are you referring to?

I don't think the size matters so far, I've played over 3GB videos and I don't notice any difference during normal playback.

Probably some process hogging your N900, running at 100% all the time, or some process is on the Virtual/Swap Memory (which is super slow). If an app is loaded into swap/virtual memory, you'll notice great performance issue and possibly the screen will stop responding and you'll need to wait very long for something to happen. If your hildon-desktop has stop responding, you'll also face this issue or the desktop may have no respond. The leaked PR1.2 seems have better management on the hildon-desktop hang issue.

Tips:
1. Try open your camera latch, and give it some time, the camera app will launch.
2. If you're stuck in an app, use CTRL + BACKSPACE to switch to multi-tasking screen, it may take a long time if the virtual/swap memory is used up and is trying to load from there.
3. Press the power button once and wait for some time might have some respond.

If you just cannot wait, the last resort would be to take out the battery, but becareful as there is risk of data damage in case it's writing data.

You mean your screen is still black even after restart? No display at all, even the Nokia Handshake logo?

If yes, then it might be your display issue, possibly loose connection or worst case, LCD problem.

Anyway, if it's not display issue, then software issue still fixable. Worst case also, just do a re-flash of the firmware.

Added on May 12, 2010, 12:32 amNSU download until 455MB? Are you sure? If I remembered correctly, previous PR1.1.1 update is only about 200mb++

Or just use the flasher tool, download the firmware to your PC. You can re-flash anytime you want, easily, and fast (less than 5 minute (actually less)).

From what I know, you're the second; The first one was someone from N900 Facebook Fan Page.

Maybe it's just the connection loose (if lucky).

Don't worry, these are all software issues and can be fixed easily, just a matter of when?

Another great thing is open source and openness of this phone. The community can easy develop app for this phone to support whatever missing in this phone in terms of software until Nokia official provide it in their OS.

Example: MMS, because current version does not support MMS, the community has develop a software for it and it's called fMMS. Currently it's already in version 1, stable version.

I find the n900 Wifi receiver is quote good/strong. So far have no problems compared to other device, better than all other phones I have, even better than my old laptop.

The "i" on the other hand, have very bad/poor receiver, keep getting weak signal or no bar.

Added on May 12, 2010, 11:24 amThere is a known bug for PR1.1.1 or older firmware with Wi-Fi, which you need to manually edit some file.
Only affect certain Access Point, not sure why.

The problem is sometimes it is not able to obtain DNS, even tough it shows connected and able to obtain IP Address.

http://forums.internettablettalk.com/showp...96&postcount=56


Sometimes, it also depends on the DHCP settings or maybe other settings. One of the WiFi I tried to connect, able to obtain IP, but the IP is the Gateway? Wierd, then later found out need to set manual IP and DNS.

Also, take note of the Wi-Fi icon, if there is a "dot" on top, it means ad-hoc connection.

It can happen due to other app as well, sometimes probably cause by swap/virtual memory, but I don't think hildon-desktop and other core processes should be transfer to swap/virtual memory as it will cause real problem.

If you wait long enough, it might start responding again but the phone might be laggy or have performance issue, best to restart. I've also seen before 2 processes of hildon-desktop and hogging on memory and processing power. Manually killed it in HTOP.
Sometimes, hildon-desktop will reset itself as well, probably due to some widgets.

Flash games might take up lots of memory and processing power. Don't forget N900 processor is 600Mhz and actual memory is just 256MB (OS processes itself already took up quite an amount of the memory); As for the 768MB Virtual Memory, it is slow so don't bother.

Plus, current Flash 9 as I know, isn't utilizing the GPU. Maybe we might see a difference in Flash 10 later.

Anyway, you can't compare it with PC performance. Possibly you can compare it with a low spec netbook and see if the netbook can play smoothly?

For farm game, perhaps you can consider playing Harvest Moon using SNES Emu, and possibly the PSX version using PSX Emu.

Nah, majority won't choose to disable flash and would actually prefer to have Flash, hence why all the fuss with no Flash. It's a feature NICE TO HAVE. providing extra is not a bad thing, but not being able to provide IS a weakness. Giving excuses is far worst. Steve argument is not valid, he's simply denying or covering up his own weakness, having his way around with words that only his fans would believe.

Skyfire browser will provide Flash experience for Symbian and Android, and it's also coming to N900.

Flash 10 will be officially available for N900 and Android OS. Not able to provide flash is a weakness, don't blame Flash when it's not supported. For those who doesn't want Flash, can choose to turn it off, or just go mobile version webpage.

What about Theme Hospital?
It's ported but the loading is super duper slow and not yet fully functional.

I didn't remove it. Not sure what happen. I reply to another post, which is added to my previous post, that's why it shows edited.

Anyway, I use the history and add it back. Hmm...
