I've had an O2 XDA Orbit for about a month. It's my first Windows mobile product. I love the range of functions. I like being able to use CoPilot with the GPS. I really like being able to sync my Outlook address book.
BUT... the thing hangs ALL THE TIME. Sometimes it hangs for a few seconds. Other times, it locks up completely and I've got to take the battery out to reboot because even the power button doesn' work.
Last week, it hung during a re-boot, I tried the PIN number a few times and it locked me out for a full day. O2 tech support didn't have a clue what was going on. I sorted it myself. (I've now disabled the PIN).
It's really annoying when you have to wait a full minute before you can make a phone call because it is hanging whilst opening up your contact list.
How do I make the thing stop hanging?

Put either the HTC or DOPOD rom on it, the O2 one is crap.

I don't know about the O2 model but I believe the HTC model already has such a function, it just needs to be turned on. It should be in settings and titled Task Manager.
Download "Audacity" and it comes with a free sd card speed test.
See it it's the speed of the sd card.
If it is then read through the "corrupt card" thread >> you will see the recommendation -- set the power turnoff time to say 2 minutes and never use the on/off switch.
You will need a soft reset in between to reset the speed of the card.

Here is my personal experience on the link I gave you:
Before I installed it - I would click the OK button in the upper right hand corner. The application would only be MINIMIZED. After a while, all the minimized programs eat up so many resources that it bogs down the phone.
After I installed it, the OK button was replaced with an X and it would actually CLOSE the applications freeing up the resources.
It is a small free program that can be uninstalled if you do not like it - so there is nothing to lose.
Now what I don't understand is why didn't WM5 give the choice to either minimize or close applications like they do with PCs

I reckon the reasoning is that if people minimize applications (which they will do to avoid launch lag) and forget to close applications (which they will do ) the device will definitely crash.
For an insight into WM5 memory management read this:
http://blogs.msdn.com/windowsmobile/archive/2006/08/16/702746.aspx
Incidentally, the O2 Custom Today plugin included with the O2 UK Orbit rom allows you to actually close an application.
in the bottom right of my o2 device is a little o2 logo that allows me to close programs manually, works a treat
Thank you
Thanks so much to everyone who has responded to my (desparate sounding) post.
I use the O2 button to close applications routinely. I don't leave them open because I know this slows things down and (presumably) increases battery usage. I don't think that is the cause of the problem.
I've already been through the routine with the SD card. I don't think that it the problem either.
The only suggestion here I haven't tried is overclocking it. How do I do it? Does it invalidate my warranty?

Same as mine. It's pretty good.
yup, it will invalidate the warranty so just hope you can take it off before it goes back if it has to, I work for o2, the people in the shop wont know that youve overclocked it and I wouldnt tell them, the repairers on the other hand might spot it so be careful
tou can get the overclocking program here: http://www.chi-tai.info/cs_BatteryStatus_XDA_Neo_WM5_iM_cs.htm
theres full instructions, read before you start tweaking it on your own. I have mine overclocked to 260mhz and I noticed the difference immediatley, it reverts back to 201mhz in sleep mode and jumps to 260 when I power it up.
hth
Do you have a skin? I downloaded a nice AppleMac style skin and everything slowed down - took me 2 days to realise the cause.
Also, the o2 icon does not always close programs. Use it then go to Settings/System/Memory , have a look in the Running Programs tab and you sometimes see something still in there that should have closed with the o2 icon!!

Not sure if this is a design function but everytime I turn the device off it returns to Today's screen.
Actually even when I toggle to screen in WMP and turn the screen back on the PPC throws me back to Today.
I initially thought it was a problem with my ROM (LSG then Custel 1.3) but after flashing to VP3G 3.0 on my 8525 (I have both an 8525 and TyTN) and without anything else installed it does that.
Any ideas if this can be changed? I'd like to open app to stay visible.
Thanks in advance for the help.
I really don't have this problem on my ROM, see signature. I have especially tested it for you to be sure.....
Perhaps flashing 1 device to a different ROM. Can you see it yourself.
that's what i figured so I had my 8525 that was running WM5.
I HardSPL, SuperCID it then flashed it with VP3G.
There is nothing else on the phone but my exchange and pop account setup, owner info and basic stuff like this.
I also have the clock shown on every apps and the extended rom unlock/mounted (though it does it with or w/o).
My TyTN is running Custel 1.3.
I just can't think what could be causing the device to always minimize open apps when the phone is turned off (standby).
It seems that some plugins force a redraw of the today screen when coming out of stb. Nothing much to do but turn off the offending plugin.
Go to settings/today and on tab for objects remove the flag for timeout. Problem gone.
Nice try, no prize - problem not gone.
This appears to be a WM6 "feature".
This discussion exists in another xda thread here, and in a Microsoft forum here.

This is a really annoying "feature" of WM6. So far no answer in the Microsoft forums regarding this. Would be glad if i could return to exactly the screen where i switched off the device or in which the timeout forced it to suspend.
If it is not possible to fix this with a registry hacking, would it be possible to develop a small helper application which saves which application was open before the atual suspend takes place and upon a wakeup reads this information and switches to the last active window ? The app itself is still active, isn't it ?
Regards,
Secuspec
Wait. So what exactly happens? I also used vp3G 3.0 and let's say I have Resco File Explorer open and my phone sits idle for 1 minute and goes into standby mode.. when I press the power button to make the screen turn on again, it still shows Resco File Explorer for me.. Is the bug causing it to go back to the today screen every time the phone goes into standby mode?
if a program is left open when the device is turned off (or screen "muted") the program will be minimized when you turn the Pocket PC back on (you're kicked back to Today).
Glad I'm not the only once having issues. Thought it may be a design (flaw) but IMO it's a crappy one. Wish someone can find a fix.
interesting, it looks like if you remove the device password it doesn't minimize the apps. kinda weird IMO.

Isn't that what you would expect if you have a device password set!?

ericc - that's exactly the problem. Are you sure you're really going to "sleep", and you aren't just seeing your backlight turn off? (you should have to hit the power button to wake it back up).
Especially annoying when driving with navigation software - I want to just turn it on and see what I saw before it went to sleep.
MikeC - that's a very interesting point. I have exchange push email going, and my system administrator pushes restrictions onto my phone... I use Zenyee Stayunlock to allow me to change the ridiculous 5-minute lockout to something more reasonable.... perhaps either the device lock or Zenyee is the culprit.

Actually not really... my Windows workstation locks I expect to see the program I had maximized still on screen not all down in the toolbar minimized. IMO that doesn't make much sense (and even if it did they should have an option to select the default behaviour).

Works fine on my Tytn with WM6 official Swedish. I don't have a device lock enabled btw.
yes if the lock is turned off the programs will stay open and full screen on resume/screen toggle.
Problem seems to only take place when the device lock is enabled, no matter how long the lock period.

Thanks for the hint samw52000! That perfectly worked for me And it also sped up a lot of programs directly after wake up -what makes perfectly sense since no other program is interfering anymore.
Long time after last reply, but still no solution.
I notice if time in suspend mode is longer that programmed in settings/Lock/Prompt if device unused for... (if you have to tap your password) then screen is same as before suspend.
I think this issue has been addressed before but I can't seem to find a good solution. Anyway here is my problem...
Some applications prevent the device going into standby. For instance a gps application (and others). Is there a way to manage which programs do this?
I would like that when Total commander runs in foreground the device stays on.
This way I can just leave it lying around when it is copying files over wifi.
I found an application which comes close to what i want. Yishins powercheck today plugin allows you to quickly turn off the power save mode. The problem is that it is a today plugin and i'm already using TouchFlo 3D. So they aren't combinable.
I'm looking forward to hearing your suggestions on this topic...
Just noticed this is posted in the wrong group. @admin pleas move this to where it belongs
I had one before, dropped it a few times.. I wrote it off as that being why, well I just got a replacement one sent.. haven't dropped it once, it's been here only about 2 weeks
Randomly sometimes it won't respond to almost anything.. I'll be trying to slide the screen, it either won't at all or will go halfway like I barely touched it. I'll try clicking on things, programs, start, whatever... it'll not respond at all, I end up having to press with way more pressure than I should have to, way more.
Then sometimes without even a reset it'll start working just about normally again.. but that's rarely, usually I'll soft reset or pull the battery for a second and then it'll be fine.. for days even.. then I'll run into it again..
I noticed 2-3 times it was because I had **** updating at the time (motweets) or was receiving email.. but I've since made everything manual regarding email, and motweets updates once every 15 minutes and the amount of tweets is limited so it's not a lot..
Still, I run into this problem, and I've made sure it wasn't a program updating but I can't think of what else would make this happen, am I the only one??
Is it because there's a way to clear cache on internets and other programs and I have no idea how? (I fully close them, that's not the problem, I know my Vogue I just can't figure this out an it seems nobody else has this problem).. Not to mention I have my internet cache's directed to my storage card so as to keep my phone memory as free'd up as possible
If anyone can help..
mine is unresponsive sometimes and i have to tap on the back of the phone to get to work again. i thinks its going out soon
That's what I thought about my old one, I figured I had dropped it to much.. because I did lol but now I got a new one 2 weeks old and I'm running into the SAME problems.. I'm assuming I must be doing something wrong with how I've got **** set-up

j18yo i think that your problem might be that to many programs run when you start your vogue that happened to me before and i hated it but then i heard of a program named "Space Reclaimer" FREE and it made my vogue much more responsive because the program stops any programs that start when you turn on your vogue or any windows mobile phone
I have the same problem usually under the same conditions. Mostly happens in the morning after the device has been off. Works fine for a few seconds then stops responding correctly i.e., the D-Pad stops scrolling correctly with a lag on touch response. I use CleanRAM and it still doesn't fix the prob once it occurs. Sometimes when I run CleanRAM it will occur. I've tried putting biotouch.exe and everyting BUT the kernel processes in the exceptions list and a Level 1 clean. Hard reset yesterday and haven't had the problem yet. If it continues to work, I'll post my settings.
BTW, I'm on a stock 6.1 ROM with a few apps.

What ROM are you running? I asume that wehn your new device came you loaded it the same as the old one. It has to be something with the ROM you are runnning or a problem with a program causing your issue.
My phone would do this periodically too, with Vin's latest ROMs. I turned off Manila and am running Titanium now. Interestingly - no lags when unlocking since. I'll keep Titanium on for some time to see if that makes it go away. I had an issue with both his current v2 and v4 (which I am running now).
Ive had to replace my screen twice and the whole phone once because of touch screen problems. Thank God for the insurance.
Ah yes... to what OP mentioned:
I do not beleive it is a more pressure thing. I do not think it is more pressure that is required but rather that the phone is non responsive. If you are unlocking and typing a PIN, it takes the PIN and all but it takes perhaps one digit every 5 seconds. That's my experience anyway. So it is just slower, as if something was consuming the CPU and UI is not responsive.

THIS..
It has to be the problem.. I have CleanRAM run every 12 hours or 6 hours because I figured it would help.. lol but now your saying sometimes it happens WHEN you run cleanRAM.. Im assuming it does something, or erases something it shouldnt?
This is like the 1 sole thing I have run on a schedule, I've turned off my email and everything to manual, I went into my startup folder and there was about 4-5 things I didn't need which made the battery 100% better than it was in terms of how long it lasts.. and I set-up this CleanRAM schedule on my last phone I THINK I forgot but I do know as soon as I got this 1 going I did it and I'm bout to delete the program completely and see if it'll help, I have speedbooster too which does a cleanup too I'm curious if it would have the same result..
I'll let everyone know if this ended up being my problem incase anyones in the exact same boat with the same apps
PS: I was doing level 3 cleans

Update: I don't think CR erases things as much as it kills processes that won't restart. Thru trial and error, I've adjusted my CleanRAM settings to where I haven't had the problem for a couple of days. I'm able to do a Level 3 cleans on a once a night schedule and during the day if need be. In settings, I have it to close all apps, launch startup progs, and display today screen. I have no exceptions listed for either running progs or startup progs. I have the most up to date version from the OTA update in the program.
The program links in my StartUp folder are: poutlook (original on ROM), sddaemon (original on ROM), WLMUpdate (original on ROM), Glossybars.exe (I added this), biotouch.exe (I added as I thought CR killing this was the source of the problem), pocketwit.exe (I added), and SIPChange (I added).
One thing I did do was delete the link for TouchPal from the Startup folder. I did this for other reasons (I use FingerKeyBoard). Not sure if this was part of the problem.
I can scroll with d-pad and no touch lag.
On a side note, can I delete any of poutlook, sddaemon, or WLMUpdate from the startup folder to save battery power?
I'm probably just a bit above a newb so sorry if I don't make sense.
Update: Just for kicks, I deleted the links for glossybars.exe and pocketwit.exe from my StartUp and it started locking again after running CleanRAM. I put them back in and it works again even after running CleanRAM. Maybe someone with more knowledge can explain this. I'm just keeping it the way it is now...
Hmm weird that you removed something not very important like pocketwit an cleanram caused problems again.. someone has to have some info on this??
I deleted everything from my StartUp folder but my SPB Mobile Shell.. I didn't have sddaemon, but I did have poutlook and WLMUpdate both of which I deleted.. then I had some other programs that aren't necessary for the phone.. I have no problems on restart or anything, and the % showed being used is stays around the 30's now instead of 40s/50s.. and when I run programs it usually reachs 50% tops now instead of 60/70% I used to get.
PS: Pocketwit isnt bad I used to praise the program but now I've tried MoTweets and.. I can't think of the other one now.. ****.. it's really good though but it seems to use a lot more phone power than MoTweets so I went back to that.
Pocketwit kept giving me problems, started saying I need to install that NET 3.5 or whatever but when I try to it says I have a later version already so it won't install, then other times it'll work completely fine.. but MoTweets I like better anyways
Ok, I give up. I restored everything to the way I had it when it was working and now I'm having problems again. After the screen turns off and I turn it back on, it locks up and won't scroll and has the touch lag issue.
Hope someone figures this out. Shouldn't have messed with success. Good luck.

This was happening with Vin's Rom for me as well. I was tripping out pressing ON so many times with no screen showing up but phone light on! I believe it could be the power settings. I disabled the "Turn off device" which I believe was mentioned in his notes about the rom.
I gave up on this problem for a while but found something when researching how to disable to cube. I used the registry edit in this thread to disable to cube post #69. I didn't do any of the other steps because I'm not having memory probs (42% with pocketwit in the bckgrd).

I noticed that biotouch.exe never shows up in the running processes menu in CleanRAM and I don't have the "lock/freeze" scrolling problem any longer and I can run CleanRam without the problem occurring. I can press any item on the screen as well with no delayed response.
However, this stops you from being able to finger scroll and do the "side to side" scroll in Messaging. I never really finger scrolled and prefer using the d-pad for scrolling so losing that functionality isn't a big deal to me.
If anyone can figure out how to keep this working so smooth and have the option to finger scroll, I'd be much obliged. It just seems that biotouch.exe craps out sometimes and locks up the d-pad. If they could both work equally well....
Hello everyone, i've been experiencing this problem for a while now: every time i put an app in the background (swipe up on gesture / middle button in traditional), Android immediately closes it for me. I keep seeing in the list of open apps (long swipe up on gesture / square key in traditional) the apps I should have in the background but as soon as I open them it's like I'm starting them for the first time, not saving anything I was doing before. So far i've been able to live with it, but now I can't postpone this problem anymore.
What i tried so far:
Restarted the phone several time
Turned off adaptive battery and battery optimization
Turned off energy saving
Didn't touch anything in the developer settings
And i got another issue probably linked to this one: in the GMail app, the notifications for multiple accounts only works to the account you are viewing, not to the others. (Example: If i'm connected to two accounts, A and B, and i'm viewing B's emails, if i receive an email on A's account the notification won't work. If i receive the email on B's account while i'm viewing A's emails, it won't work either).
Thanks in advance!
EDIT: Just in case you want to know i'm currently on 11.0.5.0 build.
EDIT 2: Link to my reply with a possible solution to the application issue: LINK

Xiaomi team for our device is at fault. If you want the best android experience you should buy Pixel phones.
I'm also having this problem. Seems that restart helps a bit for some time but not for long. It is really an awful experience to use the phone like this. Having the 4 GB version.
It's the first time that I'll complain about this phone! But the use is unbearable now! I have the 4gb version too! I hope the next update fixes things
As far as I know, this problem is common on our device. If the next update isn't going to fix it, then I'm switching to a custom ROM. HavocOS, RebelOS or LineageOS 17.1.
Never had this problem before but is indeed the first time I'm also considering a custom Rom too!
If you're rooted you can fix this using LSpeed app
Hello again, i apologize for being away for a while, but i had personal problems.

(other than June Security Patch). I'm reading the replies now, and i have to tell you that (currently) i can't root or install a Custom Rom because it would conflict with my bank's application.
So, once again, no support from Xiaomi... but the great news is that i may have found a solution for the application problem! I will link this reply to the main post, so you can find it more easily, let me know if it works for you too!
What i did:
Disabled Adaptive Battery under "Settings -> Battery ->Adaptive Battery"
Disabled Night brightness (also the plannings)
Disabled Do Not Disturb (also the plannings)
Disabled Rest mode (if any)
Rebooted the phone
Try it out with two application, and if you want to reactivate some features after the reboot, i discovered that "Adaptive Battery" creates problems only after some days since it's turned on, so i suggest to keep it disabled. For the other settings, i can't confirm anything because i haven't tried yet, so let me know.
Thanks
Finaly it worked. :good:
I was searching for this problem for a long time.
Your solution worked with me.
I want to say:
I already jave disabled adaptive battery, Night brightness and Don't disturb mode. But only Recovery mode I needed to disable it, then I rebooted the phone.
