[Q] Forcing screen rotation - HD2 Android Q&A, Help & Troubleshooting and Genera

Hi all,
If this is in the wrong place, i apologise unreservedly. It's really a question about android generally, but it's a question which has arisen specifically due to the behaviour of many of the various android builds available for the HD2, so i figure this is a sensible enough place to put it.
Enough waffle; the question:
Given the screen freezing issues associated with the gsensor/autorotate (i know this is at least relatively widespread as it's mentioned in many of the rom threads, and at least one dedicated thread), is there a setting/widget/app that can be used to force-rotate the screen and lock it in that orientation, if auto-rotate is disabled? For example, if i know i'm about to launch my browser or texting app, i can flip to landscape.
Many thanks all!

1. That is a very good idea and might fight the freezes caused by autorotation.
2. I want this anyway, because I want to be able to force a specific orientation when lying in bed. With autorotation the screen usually rotates the wrong way...
So any help would be appreciated!

I have this problem also
I've tried googling for an app of this sort, but so far no joy. Might try and create one myself. Never written something for android before, but software development is my day job, so i'd be willing to give it a crack. Crazy-busy at the moment though, so not sure when i'd get time

how about assigning a longpress-homekey something like rotate by 90° each time it is longpressed?
something like longpress-endkey menu in windows mobile devices.
shouldn't be that much of a problem to write such a program with appinventor?

I have Switch Pro Widget (it's a customizable energy control widget). One of the shortcut buttons enables/disables auto-screen rotation, so that does the trick for me.

Tmobile USA 1st day minor problems

So far, mostly a positive experience switching from my HTC Advantage. As expected, the capacitive thing will take a few days/weeks to adjust to, but I've found that a light touch does wonders.
Thanks to the xda-people & searching, I've found solutions to many problems I had (like tcpmp crashing till I got the correct cab). A do have a small list I'm looking for help on that I have not found a solution for.
(if I missed it in searching, sorry - please send me a link!)
- Automatic Phone profiles. I used to use SPB's Phone Suite, which isn't compatible with 6.5. I tried Phoneweaver last night and it worked very well - but is crashing all over the place today. Just sent them an email. Is anyone using an automatic volume adjuster with no problems?
- Speaking of crashing, getting the &*@%& battery lid off is a problem. Probably needs to work in a bit, but I can't do it without a mini-flat screwdrive, and I already put one scrach into the back of the case They just couldn't put it someone more accessible?
- Mentioned in another thread, but I can't seem to find any software that remaps any of the buttons (especially volume buttons). I've read that Voldpad & AEButtons work for other people, but nothing working here yet.
- My other big crashing problems seems centered around contacts. Adding them to my favorites is causing lock-ups about half the time, but when I reboot the changes took. Editing a contact (say adding a ring-tone) is also locking up the phone when I save/go back.
- Synching: probably related to contacts above. 1st synch works well. Afterwords, it is getting hung on contacts as well. If I delete the partnership is synch ok again the first time.
I think that's my big ones for now. I'm only 1 day in, and yesterday was pretty busy so I hope to have more time today to do some installs & play more.
Thanks for any help!!
Phil
PS - I didn't install any Freecell or Sudoku yet. I'm used to VGA. Anyone have a recommendation on ones that work very well with the HD2 (I didn't even google this yet, but thought I'd ask)

I hated the battery cover, until I found an easy way of lifting it up without tools.
use your right hand, and place your index finger to leverage the phone (face down) at the bottom of the phone near your buttons. (make sure you grip the back of the phone too just in case it tends to fly off)
use your left hand and have the thumb push up against the battery cover on the side with the indent in it. you should be able to lift your battery cover off without problems.
after 1-2 tries, it should be easier to lift off. I like the security knowing that it's not going to fall off, but it's really tight to get off at 1st.
Sounds similar to the video I saw on youtube. Time permitting, I plan on opening & closing the lid many times today (using screwdriver if needed) to loosen it up so I can take it off when needed.
----
In other news, I'm not using a screen-protector (yet) - need to read the thread on the protectors. I'm not too worried about scratches, but the fingerprint on the screen is worse then I thought it would be.
I'm carrying around a small microfiber now. Might have to find a small one in a sleeve or something to carry permanently. I have glasses, so I probably should have one handy anyway.
---
Next, a minor problem with Resco Pocket Player that I just read a solution to, but thought I'd post it for anyone else - you can't click on the screen to change settings in options. To get around it, bring up a keyboard with arrows & use those and enter keys instead.
--------
Finally - on the Sense Photo & Music tabs - is there an easy way I'm missing to specify and/or limit directories to look at? For now, I disabled both tabs in favor of Resco Photo Manager & Conduits Pocket Player. I did read about a hack to make Resco Photo work in sense, but haven't tried it yet.

Thats got to be one of the best typos' I've seen, I'd rather not shove my HD2 in someone though!
I'm currently reading on the Tmobile US forums about the problems with Messaging causing problems (although I've only seen it with Contacts so far). But I don't use email messaging much, just SMS (don't know if it's the same subsystem).
Anyway, going to try the suggestions of switching from HTC messaging to standing messaging (http://forum.xda-developers.com/showthread.php?t=556614) and see that is my contacts/synch problem. I wanted to post it in case any lurkers have a similar problem. Will try to post later if this helps.
yes sense messaging causes lots of freezes if you get lots of texts saved and having swype enabled agravates the problem.
ive had no issues anywhere else or with contacts

As for your last point: At least on the Photo tab, you can specify the Folder shown up: Open up HTC Album and go to the folder you want. Then hit Menu and select as Favorite. Then this folder will only be shown in Photo tab.
Just saw this: http://pocketnow.com/software-1/bug-hd2s-sense-may-freeze-with-contact-favorites
Sure enough, one of my favorites (ie, my wife) has a lot of notes & doesn't have the xml stuff. Will try the fix tomorrow.
auto speaker?
anyone else having their speaker turn on automatically during a phone call
That is one I'm not having, HectikDroid.
I did reply to another thread about calls that went straight to voice mail.
Still not connecting to weather serivce either (yet another thread with little replies).
Actually, most frustrating part is trying to find out if others are having similar problems or it's it me (either bad phone or accidental messed up setting or the like).
Glad to see pocketnow posting about the big contact problem I had.
Speakerphone turns on if you lay the phone down on it's face....

setting up Droid 2 for my blind sister

My sister lost her vision last year at the age of 24 due to diabetic retinapothy. She is missing be able to text message, facebook, celeb gossip... you know, the important things in life We initially bought the Droid X for her, but It's going back in exchange for the Droid 2, which should be here on 9/9/10.
Problem with the X is the Android Eyes Free Shell and the Talking Dialer make use of either a trackball or a directional pad. The Droid X has neither. It's also difficult to navigate pretty much everything blind without a d-pad. Should of thought of that earlier. Oh well, the exchange process is very easy. The Android Eyes Free team developed the software around the Nexus one i assume, which has a trackball. Personally i think a d-pad is better for a blind person, as you can press down once to go down once. A trackball you might go down 2 or 3 depending on how much you rotate it.
I'm going to be updating this thread with our progress as well as what steps we took along the way. Hopefully this will end up being helpful for someone else in a similar situation. Blind people DO use the internet (even youtube!).
Here are the initial changes I want to make:
Locating Touch Sensitive buttons
I will go to a craft store and find something to put below the 4 touch sensitive buttons on the front of the phone, this way she will be able to find them. Im thinking 4 drops of some puffy glitter glue or something to that effect. Being diabetic she's also lost somesensitivity in her fingers, so something with texture will be needed.
Removing the Lock Screen
Slide to unlock is basically an impossible task for a blind person. The Droid 2 uses the stock vanilla lock screen I believe, does anyone know how to remove it? I could potentially replace it with a "shake to unlock" or whatever, and ideas here are appreciated.
Answering the phone
Again, here slide to answer isn't going to fly. Does anyone know: If you slide the keyboard out while the phone is ringing does it answer the call? Most slider phones I've seen operated like that, I'm hoping the Droid 2 does too. She will also have a bluetooth headset which should make it easy to answer, but if your blind trying to find your bluetooth headset in time to answer the call can be a problem, so i'd like her to be able to answer the phone without a headset as well.
Hanging up the phone
Can you slide the keyboard shut to end a call? What happens if your on a call and you slide the keyboard out and then closed, does that hang up the call? Another solution would be to make it so the power button hangs up the call, surely it can be remapped do that. Or is there an end call button somewhere on the hardware qwerty?
Ok, those are the first major things. Actually dialing a call is no problem once we get past the lock screen issue. She can double tap the home button to launch the voice dialer, or she can use the Android Eyes Free "Talking Dialer" to dial a number with her finger using swipe motions. It's pretty neat actually, give it a try if you haven't already. The Eyes Free Shell and the Moto Voice Command will take care of pretty much everything else.
Thanks in advance for your help!
I can confirm that the Droid 2 does NOT answer when sliding the phone open and does NOT hang up when sliding closed. Just tested this.
Edit: forum.xda-developers.com/showthread.php?t=762101
View that thread and search the app "no lock" in the market. Seems to do what you are looking for in the marketplace. You may also want to contact the developer to see about source code or see if it was a .apk that was removed.
Also in response to the glue idea:
I would test on another device because the screen has to be able to sense your impulse as well because it wont trigger unless it has a touch by a human hand. My guess it it reads the electronic pulse by the skin and that is how it picks it up.
about the unlock screen, I can say is once you do it enough times you know where is on the screen, I usually unlock mine while its not even all the way out of my pocket, also it vibrates when you touch the unlock area and it vibrates again as you pull it to the right...hope this helps
I don't have an Android phone yet, but I've seen a nice replacement for the stock locker, called WidgetLocker. You can modify it a lot (add your own apps, widgets etc.) but the most important thing for you is that you can move the unlock slider down to the bottom of the screen so it would be easier to unlock it.
Of course, the best solution is to remove completely the locker, but I don't know whether it's possible, so I'm just giving you another option

This page has been a big help: http://eyes-free.googlecode.com/svn/trunk/documentation/android_access/basics.html
Above link talked about No Lock, an app on the market that removes the lock screen. Although it turns out she is actually able to unlock the phone blindly, but it usually takes her a few tries. For now we are going with no lock...
Also the Droid 2 has an option in the Accessibility page to enable "use power button to end call" so that has been a big help.
So far the biggest problem with the Droid 2 is the keyboard really sucks for a blind person. The navigation keys are kind of awkwardly placed, and the keys are very flat. I wish I would of known about the LG Ally, as the appears to be the best Android phone for a blind person. Has physical buttons on the front to start/end calls, and the keyboard is WAY better (for a blind person anyways). Unfortunately Verizon only lets you exchange a phone 1 time, and we already bought the Droid X. So looks like I'd have to sell the Droid 2 and buy the LG Ally on eBay. Not sure if we are going to go that route.. might just try and make the best of it with the Droid 2.
I have a LG Ally wits a protective rubber case, invisible shield screen protector, and 2 batteries which I'm not currently using. I'll do a straight up trade for your Droid 2.

Made my account to reply to this (And because I got my Droid 2 2 days ago). Will be watching this thread. My son is 2 and nearly blind. We are exploring any and all ways to work around it. I'm currently learning braille so I can teach him, and looking into how to make phones and computers more usable for him. Hopefully your sister handles what's happened well and finds ways to keep up her life, goals, and hobbies
Thanks for posting this. Good luck with the project and keep us updated, please!
Need some help here too
Hi there,
This seems to be the only forum that I can find on this subject. I will definitely be checking out the LG Ally but I'm also looking at the Droid 2 Global (which my partner has bought for himself and I have been testing out).
I am a blind person with little vision and I have to find a smart phone that works for me, as I have hit the point where I need to access my work email, work calendar, and browser functions do be more efficient and effective.
The blackberry is out, as it doesn't work for blind people through Verizon.
The IPhone, though just coming out from Verizon, does seem to have a great VoiceOver application which works great for a blind person. However, I'm not sure I'm patient enough to type without a keyboard--though it is possible for a blind person to use it.
Your points about the LG Ally are helpful for me. Does it have an accessibility application like the Droid 2 Global?
In testing out the Droid Two Global, I have enabled the "accessibility application" and checked the read out checkbox in the settings. It has abled me to see most stuff and some of the pieces you put up on the post will help. What I am struggling with is the following:
When I access any part of the browser application, it doesn't read the page of the web site or any of the links. I'm wondering if there are key combinations I am not femiliar with that would make this work or does it do it at all?
Also, the calendar is not reading things to me as well. Any ideas?
In general, is there a button that I can press, that will get it to repete something or to read a screen. I currently am just arrowing back and forth to choose something. I also can hit the OK button when typing a message to read what is in the edit box.
The last issue, though I think it would get much easier as I used it, is that to dial just a phone number seems to take a bit longer. But, I just tried using the voice dialer and it quickly got much easier. lol
I also wonder if the Accessibility application is the only one you are installing. Should I be installing something else to give me more functionality
Sorry for the long-winded questions but I really can't seem to find other assistance on this.
Thanks,

Hi Jeremy,
I think you will get the best answers to your questions on Google's eyes-free group (I'm not allowed to post outside links on this forum, or I would have given you the URL).
On that list many blind Android phone users report accessibility issues and workarounds, and the list is monitored by Google's Android accessibility developers. Android web accessibility is indeed still very limited, as is text editing support.
Best regards,
Posted my question also to the eyes-free group
Thanks for the reply. I did post my message to the Google eyes-free group, but felt I would get a fuller response here as well.

HTC Messaging jumping and keyboard shortcut

I don't know if anyone of you guys here have experienced screen jumping around the conversation thread while texting, but I've seen pretty much elsewhere. I haven't seen any similar thread around, so just to share it.
According to my interpretation, it is both a feature and a bug.
As for the feature part, the T, B and Backspace buttons are actually keyboard shortcut in a conversation thread. Once you've selected an sms with the trackpad, pressing T will get you to the top of the thread, vice versa for B and Backspace is for deleting.
What bugs me badly is that these things happen right when I was texting. Once or twice, I thought I was accidentally touching the trackpad, but considering my hand positioning and the cursor was still in the composing box when it happened, it was rather impossible.
It seems to be an universal Sense problem as well, since I came across this in multiple Sense Rom.
The best workaround I could come up with was to press B to get it back to the composing box, and use the trackpad to reposition the cursor. Nevertheless, it was still disruptive and annoying as hell.
Please share in the thread your experience/workaround/solution regarding this
Wish I could help more than to say you're not going nuts, it happens. it's incredibly annoying, i have no idea what does it. I don't use the roms that it happens in. If you like sense roms, but hate that try out myVision, I haven't seen that happen at all. Only downside I've found to myVision is the 'favs' crap that I'm amazed tmobile still tries to call a feature.
myVision is still in RC, that's the main reason why I still haven't tried it yet, but thanks for letting me know, will see how it works then
I think they only things keeping the dev from calling it complete are:
wants to add:
Will be adding 4-way reboot (when I figure out how to do it)
Will be editing updater-script so that you aren't just looking at a blank screen while it is installing (again when I figure out how to do it.)
And there is one bug:
HTC FM radio is not working on RC3.1 - working on a fix now.
I've been using it since for a few days now and have had no problems at all (I don't use the radio because I don't carry around headphones). It seems to get good battery life for a sense rom also. I think the only thing that could get me away from this rom is a Doubleshot rom with the lock screen app shortcuts like in Unity... couldn't hurt if it were updated to the newer doubleshot base either.
This is one of the many things that drives me away from Sense.
It's pretty, but I do 10,000 texts a month, and less than 100 minutes. So little things like this kill me.

[appIdea]smart sense

Thinking of what I can keep improving of this phone is becoming quite hard
just cause all developers or modders are doing such an incredible job.
However I was yet able to find a tremendous annoying issue, that could make things more pleasant if resolved
One word, auto-rotation..
the screen turns when you don't want too
the screen turns to slow
the screen get flipped upside/ down
…
So I was thinking if it wouldn't be use full if we made a smart control center
Where you can for example disable auto-rotation but still enable it for some apps
What do you think? Xd

[Q] Laggy screen response/sensitivity on T280

Is there any way to increase the screen sensitivity on the T280? I've only found one mention of the issue after thoroughly searching Google, with no suggested fix.
I'm comfortable with modifying system files such as build.prop and such, I just have no idea where to start!
The issue:
This screen is really slow to pick up touches, especially from a stylus.
When swiping (eg for pattern unlock) contact is often broken.
Even using my finger, when selecting text it's difficult to move just one letter at a time.
In handwriting/drawing apps, resulting text is extremely angular and jagged.
Here's what I've tried:
Changed "mouse sensitivity" in the settings (minor improvement)
Used 2 different screen calibration apps (minor improvement)
Installed debloated ROM (only one available; no improvement)
Removed some unnecessary system apps (will be removing more to free up space....)
Disabled settings that affect device speed such as animations
Several different stylus types (the most expensive work worst )
So, is anyone else finding this an issue? Is there a fix I don't know about? Is/are there a kernel tweak or something that will speed up screen response time?
I bought this tablet in part so I could use it for handwriting input using a stylus on a larger screen than my teeny S5. Unfortunately, the screen response is far too inconsistent and ...well, slow than I'd expected.

Unfortunately the drivers or the touchscreen hardware itself for the T280/T285 is not that good. I have a drawing app that I created myself and the touch event update rate is so slow it creates jagged lines. Best case is that it is a driver issue and we can fix it in the kernel, worst case the hardware just sucks and it is what it is. On my OMNIRom 6.0.1 SM-T285 device touch response is actually ok, it is the update rate and precision of the touch which is a problem.
Thank you so much for the quick reply, and for understanding what I mean.

Congrats on getting most of the bugs out of that ROM! It was SO disappointing to read the "fine print" on your OMNIRom and discover I couldn't use it, as it looks pretty sleek, but you're helping others immensely with your work.

Hooray for drivers being a possibility! There's something can be done about that!!
Do you find that the lines aren't quite as jagged running OMNIRom as with stock?
How would someone find out whether it's the hardware or the drivers?
Are the differences between 280/85 so extreme that I can't try anything on my own?
Is there anywhere I can "sign up" for testing any new tweaks or ROMs or kernels?
(Update on the issue: I ran the "screen calibration" test again and it says it's taken another 10ms off the response time. Not sure if I'm imagining it but it feels as if it's actually faster...)
I was also thinking, would the DPI have anything to do with the jagged appearance? Between this tablet and the 2 others I was looking at (both Galaxy - previous 7-inch and 9-inch) those had much better DPI ...or am I thinking of resolution? Those aren't the same thing, are they? In any case, it's worth checking into whether fiddling with the DPI might do any damage.

We will need someone to tinker with the kernel sources to found out. For the SM-T280 someone is working on making the kernel sources work. Unfortunately, though annoying it isn't really on the top of my list right now.

In any case, it's worth checking into whether fiddling with the DPI might do any damage.

Based on the software codepath, DPI shouldn't really affect touch performance.
I wound up returning it and picking up the 7" Galaxy Tab E Lite (SM-113), which seems to suit my needs much better. While it's much more limited in some ways - no custom ROMs, limited to KK4.4.4, same small internal storage issue - the screen response is WAY better and I can get around the annoyances (largely - no, SOLELY - due to all the things this forum has taught me over the years. :highfive:

You were right. But it was fun to play around with! And I learned a few things in doing so.
We will need someone to tinker with the kernel sources to found out. For the SM-T280 someone is working on making the kernel sources work.

I sure hope that someone figures this out soon because it's a pretty sweet little tablet, otherwise, and I can't be the only one for whom this is a deal-breaker.
Unfortunately, though annoying it isn't really on the top of my list right now.

I totally appreciate that your time is valuable, and thank you immensely for taking the time to respond.
Similar issue
Hi,
Was wondering if anyone with these issues also experienced this: While the tablet is on, when watching something for instance, if the touch screen isn't used for a bit (say over 30 seconds) when I first press it it doesn't respond at all, to get it to wake up I have to press quite firmly, usually several times, before it starts working. Once it does respond I can use a much lighter touch so it doesn't seem like a screen protector or overall sensitivity problem, it's as if the screen goes into some kind of sleep mode becoming much less sensitive.
Anyone know about this/how to fix it?
Much love,
Tom
