[Q] HID Device Latency, can anyone confirm? - Galaxy Tab 7.7 General

I also placed this in the accessories forum, but it is more related to the actual Galaxy Tab.
Can anybody confirm that they are having the same problem on their Galaxy Tab 7.7? If I use a bluetooth keyboard, it pairs and sets up and works fine, but if I don't press any keys for exactly one second, then press a key, there is a latency of about 0.5 seconds for the key press to register. If I continue pressing keys there is no latency, as long as I press at least something without letting one second elapse. As soon as I have pressed nothing for a second, I must wait a second for the keypress to register. I don't have this problem on my Galaxy Nexus, and I can recreate it with both a bluetooth keyboard and a wiimote connected through bluez ime. However, if I connect the wiimote as a non-hid device through wiimote controller, there is no problem whatsoever. I believe there must be some latency setting to save power, but am not sure. Can anyone advise? Perhaps there is some way that I'm not aware of as an alternative to pairing HID devices without this problem? I play games with an external keyboard, and it really messes me up. Thanks! I should note that I am running the stock rom and my galaxy tab is Hong Kong version (I live in Mongolia).

confirmed
...and it indeed is anoying.

o2 XDA IIi & Power Save & Keyboard

I've been experiencing some strange problems with the power save/ auto power off functionallity. I'v experienced a couple of issues with my XDA IIi not powering on due to a flat battery.
I have since identified the cause of the flat battery, the IIi fails to power off after the set time of 2 minutes. If I do a soft reset then the power off functionallity works correctly. I'm not sure if this is a IIi ROM bug, or caused by software I've loaded, the problem normally occurs after using TomTom for a few hours with the IIi connected to the car charger. The on/off works perfectly.
Final question when using the keyboard mode of input should there be a '£' symbol instead of the '$'. I'm sure on other pocket PC's the keyboard shows '£' by default. I've checked the regional settings and these are set to UK, I can select '£' by using the symbols layout. Just seems strange.
Don't know about the rest but the missing £ symbol on the on-screen keyboard does my head in as well. @ and : symbols on main keyboard be nice as well!
Anyone know a piece of software that allows you to Choose custom keyboard maps?

reboot problems

Haven't noticed- but has anyone else reported reboot problems?
I find that sometimes i have to do several (soft) reboots before it will allow either the hardware keyboard or the software keyboard to function at the enter password stage. Alternatively if i wait for what seems like an eternity the option might or might not appear. It seems as though the machine is busy trying to do something else.
my machine is branded as the Ameo. I did contact HTC via email but they told me to go to t-mob....
I also notice that when i am using media player and turn the backlight off using the button on the side rather than the light button on the h/w keyboard the unit locks up. i only use the media plyer because my sony bt headset is unable to control any of the 3rd party players that i have tried.
Has anyone got a newer rom that has resolved this problem- don't care too much if i lose the t-mob branding cab files.
thanks in a advance

Didn't find that kind trouble with my dopod u1000

Bluetooth keyboard tip.

I purchased a Logitech bluetooth keyboard for use with the Note 10.1. Initially I was excited, but that excitement turned to irritation when I realized that my typing experience would be constantly interrupted by the words "English(US)". After some trial and error, I quickly found out that it was cased by pressing the key combination Shift+Spacebar, which activates the Samsung Keyboard's language switcher. Apparently, I hit this combo every time I capitalize an "i" when typing quickly.
After some trial and error, I found a decent solution. I downloaded the 4.2 Google keyboard, and problem solved (Initially I tried a number of other virtual keyboards, but each of them didn't play well with the quick FN options of this keyboard, and I was searching for full functionality). This also removes the full word deletion feature of Sammy's keyboard, which begins deleting entire words when the backspace button is pressed for X-amount of seconds), which I find to be very annoying.
The only problem left happens when reconnecting my bluetooth keyboard, which causes TouchWiz to default back to Samsung Keyboard. Fortunately, the virtual keyboard can be switched back to Google's with just a couple taps.
Anyways, hope this helps.

Keyboard issues

Hi all,
so I have my Yoga Book - Windows version - for several days now. I am very happy with this device however there is one issue with the keyboard I just do not know how to solve - except for connecting external keyboard.
In general use its fine but it does not cooperate with games - you can not use key combinations (wd;wa,sa;sd) to move. As soon as you press "D" while holding "W" the keyboard stops sending continuous imput data. You can hold "W" and tap "D" to move right strait right (not forward/right) but it is a single imput... you can not hold "D" for continuous imput while holding "W" at the same time as in normal keyboards.
This seams very strange to me as you in fact CAN hold several key for continuous imput just not the character keys. For example: shift+W (2 keys) will give you continuous imput of capital "W" and crtl+alt+v (3 keys) will give you continuous imput of "@" sign. Clearly the technology supports multiple simultaneous "key" press, it just does not behave like regular keyboard.
I believe that this is an issue of halo keyboard's drivers but I might be wrong. Anyone have any glue how to solve this?
You can use the micro-usb port and bluetooth to connect an external keyboard

Well........ obviously. I know that, but you certainly do not have external keyboard all the time. I mean... it kind of negates the point of having 2v1 tablet/notebook if you have to have external keyboard anyway.
Hey,
so after few more test I found out that the same issue applies to arrow keys as well - meaning no diagonal navigation in file explorer, table documents or navigation services (google maps). So I have contacted customer support - long story short I should do factory reset or send it to service centre.
I am still convinced that this is the issue of drivers so I was wondering... could anyone with Yoga Book test this issue?

This is indeed an issue, exactly as you have indicated. Factory reset / sending it to the service centre will almost certainly be a waste of your time.

Thanks for the info.
Anyone else? The more the merrier

That sounds a like reasonable problem to me, I am guessing that this is not a real keyboard and they probably tried to make it simulate on screen keyboards which most of them do not properly support multiple modifier keys thing. I do not have a way to try this on the android keyboard but the ctrl modifier seems to work.
I just wished that the pen and the keyboard worked at the same time. So I do not have to constantly switch.
Please, take a look at my post, I list a few files you can modify to change the behaviour of the keyboard/touchpad:

Nvidia Shield TV (2015) random problems with Apps,Leanback UI and Controller buttons.

Hi Guys, After a random problem one day that included missing apps on the home screen and controller not functioning at all -- I did the following:
Memory card in card slot removed and re-inserted (32gb set as storage and many apps transferred to it freeing up the first 16gb). Rebooted shield and could now find apps , but controller was still only working via USB lead connected to Shield TV. Previously i had experienced similar problems and this had worked before, along with holding controller buttons for 20+ seconds to reset it.
Next step was:
I fully charged the controller as this had proved to be a problem a few times before when having strange controller issues. THIS WAS WHEN I REALISED the following also;
1) Had to input all account details again for Google account, Nvidia Account, You tube account, Steam account etc.etc..
2) Home button no longer works as the home button and also cannot double click to get the screen showing all open apps. It does make audio clicks as normal AND does show the streaming options/picture saving options when you long press it, (so the button is functioning of sorts.) I have since realised that the back button next to the Nvidia light button now works like the home button but you cannot double click it to show all open apps.
3) When I click on the google icon at the top left of the home screen next to the KB icon for voice searches. It does not work. ( though you tube speech searches work fine) It does accept searches after pressing the Nvidia button though when on the home screen.
4) The developer options in the settings menu were always on previously but, now it says that these options are on but "unavailable for this user" when pressed and are greyed out.
5) on/off sensor button on the top of the shield no longer works. (this is very similar to my wife Shield upstairs but hers is a 2017 model. She uses the remote or controller to turn off via the settings menu.
So......thinking of just resetting the Shield to factory settings and starting again but wanted advice before doing this and perhaps adding to the issues???
It seems to me that given all the different problems this is the only way??? My gut is actually telling me that it's an update that has happened and it has confused the 2017 model with mine???? or am I just seeing GHOSTS???
Any constructive advice would be appreciated.
