Acer Iconia Tab - touch screen glitch?!

A couple years ago, my husband bought me a tablet for valentines. It worked great for a couple of months, then the touch screen started glitching. I could press an icon on one side of the screen and the tablet registers it on the complete opposite side. I've dug it out again in hopes of fixing it, but so far, nothing has changed. Does anyone have any idea how to fix this?

I believe there was a firmware update that fixes these issues as this was an issue on the w500's I know. If you go to Acers website and go to support. You should be able to choose tablets/your model and do a full update to correct this issue.

[SOLVED] Help needed with ACPI accelerometer - Acer Iconia Tab W501

Hi,
I am trying to get the accelerometer working on my Acer Iconia Tab W501
In windows, it reported as a BMA150 device, so I have that driver loading on boot.
After months of googling and making a mess in /sys, I still have not got the device working. I was working under the assumption that the device hangs off the i2c bus, but a "lucky google" today uncovered that it is showing up through acpi - acpid is present in my daemons array of rc.conf and the kernel module acer_wmi is also loaded.
The device is certainly sending signals to the kernel. Upon boot, dmesg ends up as follows:
[ 11.689709] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
[ 12.108374] EXT4-fs (sda2): re-mounted. Opts: commit=0
[ 12.148026] EXT4-fs (sda3): re-mounted. Opts: commit=0

[ 22.459133] wlan0: no IPv6 routers present
Now, if I rotate the device, and run dmesg again, I have the following:
[ 1255.189705] acer_wmi: Unknown function number - 5 - 1
[ 1257.363688] acer_wmi: Unknown function number - 5 - 1

[ 1308.653700] acer_wmi: Unknown function number - 5 - 1
[ 1308.784623] acer_wmi: Unknown function number - 5 - 1
acpi -V does not show the device:

[ 4.824909] ACPI: Thermal Zone [THRM] (61 C)
[ 5.220895] acer_wmi: Acer Laptop ACPI-WMI Extras
Yet, running acpi_listen generates the following when the tablet is rotated:
PNP0C14:00 000000bc 00000000
PNP0C14:00 000000bc 00000000
PNP0C14:00 000000bc 00000000
PNP0C14:00 000000bc 00000000
So, it would seem the device is working and sending data to the kernel/drivers, it appears some config is needed to get it properly recognised and an entry in /dev generated.
Really hoping there is an acpi expert around who may be able to help me get the device properly recognised and configures, ideally, as a /dev/input/js*
Cheers.

There is no need to patch the kernel anymore as current kernels have the acer wmi accelerometer patch merged.
Ensure you have the kernel module acer_wmi loading and then the events should be propogated. acpi_listen should show the events.
Using the code from here: http://www.jezra.net/blog/Python_Joysti … ng_Gobject i have written a little daemon that monitors the accelerometer and automatically rotates the screen based on it's position.
Cheers.
[EDIT] Being a laptop, I am guessing the accelerometer is possibly on the hard drive?? used for shock protection?? So if that is the case, I am not sure you will be able to utilise it in the same way as a tablet's accelerometer. There are articles on the web for setting up hard drive accelerometers in linux. The other consideration you need is that the accelerometer may not be on acpi. It could be on the i2c bus (commonly where sensors such as fan speed, core temps etc are located), in which case you will need the i2c driver to get the accelerometer events recognised in the kernel (ensure i2c kernel modules are loaded). So check exactly how the kernel detects the accelerometer, is it on acpi or the i2c bus?[/EDIT]

Facebook Messenger VIdeo call in acer iconia tab 840-FHD

Hi everyone!Just wanted to ask, has anyone tried video call using facebook messenger app in Iconia Tab 840-FHD?Thanks!

I have not been able to use my micro SD card that I bought for my Acer iconia tab 8 from day 1 as it is not functional due to whatever changes that were made prior to boxing and shipping out to the public. On the box and in advertising it is listed as a feature which constitutes fraud in my opinion. And if there is some round about way of using it that is not good enough. You should be able to utilize the card slot/function just as you would if it were a camera or a laptop computer. Even though I have not been able to use it I have left it in my tablet and when I turned my tablet on I got a notification that it was damaged and to try to reformat it. It's funny that I can't use it but the tablet somehow damaged it! Double whammy! So what is Acer going to do to fix this situation for all of us who have purchased tablets with useless card slots? No excuses or be either. Consumers, like myself, are tired of being lied to and taken advantage of. Yes laptops and tablets are more affordable then ever but that does not mean quality and customer service should be null and void because we are getting such a good deal.

Acer Iconia Tab 8 A1-840 FHDSD card mount problem

I bought the Iconia tab 8 (A1-840 FHD) and was disappointed. Due to incorrectly configured firmware - SD card when the device is connected properly mounted within the system (such as an external USB drive), there is no way to transfer files to it (the card is locked for writing applications) can not be set as a cache for Google Music, no connection mode as USB drive when connected to a computer. In fact, it is not working appendage and is not intended for storing information. When can I expect to fix this problem? Why was it decided to change the default for all other tablets on the market functionality?

Acer Iconia Tab A500 and UMW190 USB Modem?

Can the UMW190 USB modem be used with the Acer Iconia Tab A500, or is this tablet supposed to be compatible with Verizon 3G/4G?

I'm sorry but the Acer Iconia Tab A500 is not supported by Verizon Wireless. This tablet is not one of our devices.
Thanks very much for your posting!

Cannot transfer from ADE to Acer Iconia Tab a500

I have used my Adobe ID and password and installed ADE on my pc (XP), but ADE does not recognize my Acer Iconia Tab a500, which is listed as a supported device. I have registered the Iconia tab and also authorized it with the same Adobe ID and password. The installation instructions tell me that my e-reader device will appear as a new bookshelf in the library when the device is connected to my pc, but it does not, so I am unable to transfer from my pc to the e-reader. Any ideas?

I just got an Acer Iconia A500 for Christmas and was going through the same problems as "cantreadit". Since I'm not the most technically advanced person in the world (I'm an old fart in his 60's), I was panicking about not being able to use this part of my tablets capabilities, and started looking for a cure on the internet (Acer was almost no help). I couldn't get past the sign-on to Adobe ADE, and always got an error message. I saw a comment about a "time-expired" error being caused by the tablet and the computer mot having the same time shown, but my tablet was the exact time as my computer. When I went a little deeper, I found that my tablet didn't have the "TIME ZONE" marked correctly (mine was set off of GMT, the default). When I tethered my tablet and computer together and had both open to the time I reset my tablets time (the tablet doesn't set to the second, so I waited until the computers second hand got to the exact minute and clicked on the tablets clock - I don't know if you need to get that exact, but....). When I went to my tablet and signed in, this time my authorization was accepted.
Note: Adobe ADE still doesn't show my tablet as connected, and I can't download from Adobe directly, but (being an "old fart") I always save my books first to a folder on my computer before opening them to ADE. When I went to my tethered tablet and copied the folder with (the DRM protected) e-books on my SD card, then went to LumiRead, then settings, then to "manage my book folders" and added that folder to the folders that LumiRead looks at, ALL the books were there and readable. Saving the books to a folder first (which my Techno-Geek" son and son-in-law said was un-necessary) seems to have worked out good for me.
My last concern is that I don't know if Overdrive will also "see" the ADE authorization and let me download books from my local library on line (which I use a lot for my dedicated e-reader), but I'm going to check that out later today (here's hoping that works too).
This may not be the same problem that the rest of you have been facing (my problem may have been too simple for the rest of you guys to miss), and it may not be the complete cure (I still have the Library & Overdrive to checkout). Also, the rest of you may have trusted the system to work properly, and not "stupidly" saved the books you bought to a folder on your computer (like a skeptical "old fart" like me would do), but for the other "Old Farts" out there, this may be the cure your looking for (no matter how simple it may be).

Touch Screen Glitch

Hi there,
Last night my touch screen starting glitching. It is located where the C V B letters are on the pop up keyboard (but also affects the unlock swiper and general clicking in that location) I haven't dropped it, got it wet or any other kind of damage so i'm a bit confused as to whats happened. I've also cleaned it so there is nothing on the screen causing this. in fact if i hover my finger over the area it sets off the glitch, so i'm pretty sure this is a hardware issue. It may be worth pointing out that my home button has been unclickable for months now and i am using the home button you can find on the accessible settings. This now has a habit of zooming around the screen thanks to this new glitch. I am out of warranty so I can't even speak to the apple support about this without having to pay £25! Does anyone have any ideas?
I have been thinking about getting a new one but it would be nice to be able to fix it instead. I've committed to much of my life to Candy Crush to want to start all over!
Thanks,
Minnic!

S920 Touch screen glitch

Hi, I have an ideaphone S920, and I have a problem with the touch screen, when I playing a game, I am unable to perform a multi touch in a game example Shadowgun. The analog direction key reset (like not pressed) during I pressed action button.
Or maybe watch this as a sample

thank you
Moderator Note; subject edited; phone type added

I have same problem with my s920 and will be other people problem who want to buy this phone, this issue is suck... I can't play games, but this phone has high tech, so the conclusion: this phone is useless... I hope Lenovo can fix this, because I think this is only software issue, I have read some ppl use cusrom and this issue is fixed (Viberom), but this is not official and hard to do for ppl who don't know how to root and flash.
People will not buy this phone if they read this issue... this is a major issue for a phone which can play most latest games but you always lose because you can't control the game...

Acer iconia tab 8 w1-810 touch screen playing up

hii am new to here and to tablets. i was trying to get the screen to stay on longer, didnt manage it because the pc settings said it was longer. anyway, i think i callibrated the screen really wish i hadnt because now the touchscreen stopped working properly i couldnt even reset the tablet.it ended up getting switched off and now it wont let me put the password in.#does anyone know how i can fix it. i got it from the 3 shop 2 weeks ago so am thinking it still in guarantee.

The easiest fix for a screwed up screen calibration is to plug a USB mouse in and reset the calibration. That requires one of the microUSB to USB adapters though. If you don't have one see if you can borrow one to get it dealt with. In the long term you're probably going to want one of the adapters so you can plug something like a thumb drive in anyway...

Acer Iconia Tab 10 A3-A20FHD-K8KK

The tablet is frozen on the Language selection screen and won't go any further. The screen is unresponsive. I've done the reboot to wipe and reinstall to factory settings as well as "reboot system now" by holding the power and volume buttons. None of it works, it simply returns to the language selection screen with an unresponsive screen. The tablet is only 3 months old.

Acer wants me to send into their service center in Temple Texas for service. I would like to know if anyone else has experienced this issue with an Acer Android Iconia Model similar to this. Looking forward to comments or information relative to this issue.

Acer R7 571G touch screen with PhotoShop. Art Rage 3 works, but PS does not.

The title says it all. Does anyone have/had this problem?
I've been looking all over the place for a solution but nothing works. I tried adding the PSUserConfig.txt to the adobe PS CC 2014 Settings as mentioned on one of the websites but it still doesn't work.
My problem is that I can't draw using a brush with the pen provided with the laptop. I tried it with art rage 3 and it works. Am I missing a certain setting in PS to enable it?
If anyone can shed some light on my problem that would be great!
Thanks.

Iwhy can I not figure out how to view my I cloud account on my acer iconia tab? I need to be sure that all my pics are online so that I can delete them off my phone for the space. do i have to sign in on an actual computer first? I own iPhone

is there any way to sync all my pictures to my acericonia tablet from my iphone?

whichever app store you are connecting to, hyou need a credit card with an address in that country. Also, itunes gift cards must be in local currency too.
If you are in japan, you need to use the japan app store

Droid 2 global home screen glitching?

I recieved my first droid 2 global and after about an hour of using it, the home screen would start flipping to another screen about every 2 seconds. And it would always be the last thing I selected. For example, if I was looking at my contacts and hit the "home" icon, it would go to the home screen for a few seconds and then flip back to my contacts and continue doing this everytime I selected "home." It would also not let me get to the app screen at all.
I did run a virus scan, nothing came up and I didn't download a single app. About all I did was set up facebook for android and add a few contacts.
I took it to a verizon store and the man there had no idea what it was, so after putzing with my phone for an hour including doing a factory reset, he said they'd send me a new one.
BUT I had the same problem with the second phone and I'm completely frustrated and clueless. Anyone have any insight?
[removed unnecessary links]

ATT: NANCE, YOU SAID IT. I MEAN, YOU REALLY DID HIT IT RIGHT ON THE HEAD!!! "
My Droid x2 locks me out of my own phone, while in the middle of a text or phone call it just decides to lock itself.
Unlocking my phone is a pain because the touch screen glitches as I try to draw in my lock pattern.
My phone started muting itself on/off numerous times during a phone call with my boss >:(
If I am lucky enough to get my phone unlocked and get to my home screen sometimes it begins selecting apps
or m contacts or the dialer and then freezes.
It restarts maybe 2-3 times a day. The one time I drop it (it started doing this after it fell off my lap as I stood up from sitting at a restaurant.)
And finally just about a week ago it began to start deleting my own contacts..
I loved this phone until it decided to run itself? I Still likr it though,

Iconia Tab 8 W W1-810 suddenly stopped the auto screen rotation

Hi. I´m havving trouble with my Iconia Tab 8 W W1-810. It suddenly stopped the auto screen rotation and now I can´t find the "enable screen rotation" checkbox. I only get the chance to put it in landscape or portrait but not in auto rotation. How can I enable auto screen rotation again? I will very much appreciate your help.

Thank you, Justin! I tried that but, as I no longer had an automatic rotation checkbox, I couldn´t solve the problem. The solution came through the Acer Chat service. Acer technician Mukesh was very kind and patient, we tried every possible option but the auto rotation option was not available, the only way to get it back was to install the suggested drivers: http://global-download.acer.com/GDFiles/Driver/Platform%20Drivers/Platform%20Drivers_Intel_10.18.10.3643_W81x86_A.zip?acerid=635664922342452308&Step1=TABLET&Step2=ICONIATAB8W&Step3=W1-810&OS=ALL&LC=en&BC=ACER&SC=PA_6 After installing these drivers, I recovered the automatic rotation checkbox and could solve the problem. I am very happy that I could solve the problem and very pleased with Acer´s customer service. Thank you for your suggestion. Kind regards, María Inés.

Iconia Tab 8 W Touch not working after update to Windows 10

So, I have an Iconia Tab 8 W which came with Windows 8.1. I updated to Windows 10 but there seems to be some issue with the default graphic card driver since the touch doesn't work (works during the installation process so it's not a hardware problem). I managed to plug it into a powered USB hub and get a classic mouse-keyboard setup working but the touch is still dead. I found drivers on the ACER website but not only do they not have any sort of "setup" or "install" file, the Graphic Card doesn't show at all on the device manager. So, the "update driver" option is not an option. I've tried reverting to Windows 8.1 but the place where this option should be doesn't show it. I can only clean up the PC or boot into safe mode. Tried both, none works. As a last resort, I downloaded the Windows 8.1 media creation tool and booted into it to reinstall Windows 8.1 but now it asks me for the Windows key which is no where to be found. Anybody got any ideas?

IIRC the touch driver and te graphics driver are two quite different things. The touchscreen digitizer looks to the system like a USB device, so a problem would show up in Device Manager either as a USB problem or a HID problem. Try W10 again but this time look into the different secions of DM for the issue.
