I have a softwinners A20 7" tablet with. Initially it worked great with no issues. Now, however, when I plug in a mouse or 3G broadband dongle via OTG, the touch screen functionality on my tablet freaks out (i.e. touching on location causes one or two other locations to be touched as well). Is there an app that can fix this, is there a setting I need to adjust?

I have a Lenovo IdeaTab S6000 and I recently purchased the Red Samurai/GameStop V2 branded Bluetooth controller and I'm finding that when I connect the controller, a mouse cursor appears on screen that can be semi-controlled via the analog sticks. This essentially causes none of the compatible games for the controller to improperly function. Within my tablets setting menu is an option to change a mouse's cursor speed (something not present on my HTC One, which the controller works perfectly on) and I was wondering if this option could be a factor in the overall problem and if disabling this option is possible. I have spent the past two days trying to remedie this problem and have had no luck so any kind of support would be greatly appreciated.
Also, this being my first post, I apologize in advance if this was posted in the wrong area.

Necroposting, but I figured I'd add to the conversation:
The only gamepad that I've gotten to work with this device (as a gamepad) is the Moga Hero. Connecting was always finicky at best and would require a full reboot, and immediately connect when it powers up. Otherwise it wouldn't pair at all.
I've tried the Red Samurai v2, the Nyko Playpad, and most recently the Mad Catz C.T.R.L.R. Invariably, the mouse mode works and works very well, but the gamepad mode always does what was written above.
In trying the xbox 360 gamepad, it blinks but doesn't connect.
As a lark, I purchased a Asus MeMo 7" HD tablet which has the same MediaTek chipset (8125) and the same exact problem exists with that device too (mouse mode works, no gamepad). Both the Memo and the Lenovo tabs are on the same version of Android (4.2.2) and the same kernel (3.4.5) on the stock rom. I assume it's Mediatek's fault, in which case HID gamepads are a no go on these devices.
Unless someone has other information, which would be much appreciated.
Oh, wanted to add something: when the C.T.R.L.R. connects in gamepad mode, you get only a cursor. When I connect my bluetooth keyboard, the multimedia controls start working. Not sure why that is.
HI! I have a problem with the wifi hardware apparently. When I try to enable it after a few seconds returns to the Off position The problem occurs after replacing the touchscreen with a non-original even if it works perfectly. Do you think there may be a relationship between the replacement of the touch screen and the problem of the wifi? I had thought of using an external usb wifi adapter for Android but I have not found anything. Can you recommend some other device to use the wifi except the 3G dongle? The tablet is a Mediacom M-MP1010i.Thanks.
I'm finding the pairing of the Folio Keyboard with my Nexus 9 to be problematic. I'm not sure if this is because there's an issue with NFC on either device or I'm just doing it wrong.
Pairing the keyboard using only bluetooth works but needs to be triggered by selecting the already paired with keyboard in bluetooth settings and can take 10s of seconds before it is connected. I expected that the keyboard would connect as soon as it came in range of the NFC chip, but it doesn't. I think NFC at least partially works as the keyboard is detected by the tablet as a trusted device via NFC. When I follow the directions to pair the keyboard via NFC by placing the tablet on it in the right manner it does not pair though I hear a tone when the doing it, that doesn't happen when I change the orientation of the tablet. From this I conclude that the NFC hardware works but something in my use of it, the configuration of the tablet or a system bug is stopping it working properly.
1) Is it a reasonable expectation that I can be expect once pairing has been completed that placing the tablet on the keyboard will be recognised by NFC without having to lay the tablet in the manner described in keyboard documentation?
2) Assuming the desired outcome as described above is possible will this trigger the tablet to turn on bluetooth (if it is turned off) or is it necessry for bluetooth to be either manually turned on, left on or find some other mechanism that triggers bluetooth to be turned on in order to connect the keyboard?
3) Is it a reasonable expectation that keyboard and tablet to be quickly connected (in a second or so) via bluetooth?
1. Once they're paired. They're paired, no need for nfc.
2. It will not turn on bluetooth automatically. Just leave bluetooth on at all times.
3. Mine connects pretty quickly once I learned the proper method to do it, that being with bluetooth on, slide the camera portion of the table slowly over the portion of the folio just above the number row. And visa versa to unpair.
The only annoying thing about this keyboard folio is the fact that I need to turn back on the "hardware input" to either see the on screen keyboard when not using the tablet, and turn off the onscreen keyboard when using the folio keyboard. I wish it did that automatically. I'm either missing something, or need to figure out a way to do that with tasker, via touch imputs or something.
Yeah, once you connect via bluetooth, NFC is no longer needed.
The frustration I am experiencing is that once the keyboard is paired and connected...if I turn bluetooth off or it disconnects, it won't automatically reconnect the next time BT is turned on. Am I missing something here? It's like the keyboard is asleep and the nexus can't find it to connect to.

I generally just touch an input then hit a button on the folio keyboard. In about 1 or 2 seconds the letter will show up and the on screen keyboard will disappear. From there I just type normally.
I was using my wireless Logitech desktop set but I noticed some lag after not using it for some seconds. When I keep using the mouse or keyboard there is no problem and everything works fine. But when I stop typing or stop mousing for longer than three seconds, the tablet doesn't recognize any input anymore. When I move the mouse or use the keyboard, nothing happens, but after two seconds any input is recognized again.
So I have to keep typing or else I have to wait some seconds to let the tablet recognize any input. This is unworkable.
I tested it with two desktop sets with two different Unifying receivers. When I use a corded mouse or keyboard, everything's fine. It seems to me that there is some sort of logitech standby mode which the tablet can't handle or something.
What can I do abaout this?
Added logcat of connecting usb, a freeze moment, and the disconnection. But I see nothing wrong there...

I bought an other Logitech Wireless mouse (standard receiver, no Unify) and that one works perfectly. So it looks like it has something to do with Unify, not wireless in particular.
Anyone?!
The Shield tablet has the same issue:

Maybe it has something to do with the Tegra K1?

It is really annoying. My Shield Tablet is fantastic, except for this issue with the keyboard/mouse. Sad panda.

And no solutions yet. Maybe a different kernel will work, but I like to keep my N9 stock (the first months hehehe)
Any solution?
Has there been any solution to this issue yet? I too am having the same problem.
Work Around
I have a work around that seems to fix this issue. For this to work you will need to be root. Also note that this solution will cause all USB devices to remain on at all times and will not survive a reboot. My experience is mostly with linux and very little with android. I expect someone should be able to modify the following script fairly easily for a more permanent solution.
Open your favorite terminal emulator and type the following four commands pressing enter after each:
su
for i in /sys/bus/usb/devices/*/power/control;
do echo on > $i;
done
This script toggles the power control setting for all usb devices from the auto state to always on. Hope this helps!
I have a slight lag with my logitech controller through USB OTG. It's just a split second lag, but it's there right from when you plug it in. Makes it unusable for gaming. No issues whatsoever with my Logitech bluetooth keyboard however.
Recently I got myself a Sculptor 16.1'' external portable monitor that has multi-touch and gravity sensors. The monitor claimed to support many smartphones including ours as well as some others like ROG Phone 1/2. While most other functionalities work (screen outputs at 1920x1080 @ 120Hz, USB-C Power Delivery works), touch and gravity sensors don't work as expected. Haven't tested about audio, but at present I'm not able to redirect audio to the monitor at the moment (the monitor seems to use HDMI for audio).
I'm currently on Havoc 3.5 GSI, with Trinity kernel and MR3 vendor. Can confirm that hid_multitouch is built into the kernel according to the kernel config. However, I couldn't find anything about how to configure the external touch panel and gravity sensor, despite both of them have been properly detected by the system:
1. A CH340 USB-Serial port (1A86:7523) which I believe is the gravity sensor. This device can be picked up by apps like Serial USB Terminal.
2. A Silicon Works SW4101C (29BD:4101) which is most likely the touch panel.
Some information online suggests me to create an IDC for the touch panel's device ID (at present it's identical to that of qwerty2.idc, except I now specified the device is an external device), and some even suggested to patch the kernel's hid-multitouch.c to add the device's ID and information into it, but hid-multitouch.c suggested otherwise, that a default method would be used for unspecified HID devices (that only devices known to have some quirks should be included along with the code for the quirks). I checked the stock ROM's /system/usr/idc and found nothing about external touch panels, either. (If anyone has experiences with such on stock ROM it'd be appreciated)
The gravity sensor is not really working at all (maybe this requires a specialized USB serial app). For the touchscreen part, I could at best get working touches from upper-left part of the screen (about 2/3 of total screen, I think), and only when the phone is in landscape mode (in portrait mode the touchscreen does not function at all). However, it seems sliding works on the entire screen as long as the touch is started from the area that has working touches. Touch is still unstable as some incorrect touches may occasionally occur (probably cable/power related). Also, my phone would generate a tremendous amount of heat when the monitor is attached, and doesn't seem to be able to boot properly if it's been overheated (like about 60-70 celsius).
Not sure if external touch panels are still new, or that such is not really practical for Android smartphones to use (compared to desktops and laptops), the information I could find about this is very limited (that it might require some vendor-specific system modes to function properly, which Huawei and Samsung phones seem to provide). I intend to use this panel as a substitute for my Pixel C which is now showing its age, as it could not handle certain recently released games very well anymore.
After some research it seems setting the phone's screen size to 1920x1080 will make the touchscreen work on the entire screen, although one may need to set the density as well to keep the size of items the same as before.
Code:
wm size 1080x1920
Please note that you'll need to manually revert the resolution later on. The resolution you changed here persists across reboots!
Code:
wm size reset
However, the touch panel is still erratic and can cause issues with games where touches may not work as intended (multi-touch does work). Not sure if using a different cable/adapter might help, as similar issues can happen on phone's own screens as well. The use of such monitors may be limited for now as I cannot find any way to enable things like desktop mode, or get the touch panel to work when the phone is in portrait mode.
EDIT: Not sure about the monitor itself, but even with some better cables and adapter the touch panel is still not in a good conditions (either it would stop responding, or it generates unexpected touch signals). A 65W power adapter connection is required to properly function (30W connections is not enough). Guess I'll just use it for other non-Android purposes and get a real tablet (like Galaxy Tab S6) instead...
I did try searching about similar topics regarding external touchscreens on Android. However, the ones I could find were mostly quite old, dated when Android was still at around KitKat or even earlier.
As for audio, I couldn't find anything about it anywhere in the settings. And I only just realized some Type-C cables are rated only at USB 2.0 speed (which is the case for most charging-oriented cables, despite them being rated 65W or even 100W).
I didn't know there is such a touch screen portable monitor. Is it convenient?
