Now, I know this is not the ideal place to post this kind of issue. I have already posted a thread on the Yarvik Support Forum, but I have also read (on their and on this forum) that their support can be a bit... unsupportive. So I would like to repost the thread I have created there, here.
Dear Yarvik Support Team,
My sister and I have quite recently each bought a Yarvik Xenta TAB10-201 tablet. My sister purchased it first, and I, being the forever criticist I am, followed a week later.
In general I am impressed with the tablet. It provides good quality for its price, and while it obviously cannot be compared to 'main brand tablets', it still is a very good tablet.
However, there have been a few things that bother me about the tablet and prevent me from really enjoying it, and I wonder if you could be able to help me.
The tablet sometimes has the issue that it does not register the touch inputs correctly. I mainly notice this while browsing the web (using Chrome & Stock webbrowser);
it can be very hard to open / close tabs, and when I am scrolling the tablet often opens links that I wanted to scroll past. It then can also be hard to open the links I did want to open.
Now, the problem described above is not that big of an issue. It can be an annoyance and I would like to see it fixed, though. The bigger problem is that when I hook up my tablet to the provided charger, and I want to browse a few webpages and / or want to play a game on the tablet, it does all kind of 'phantom touches'. What I mean by that it is that while I do not press on that particular area (or do not even press at all), the tablet still seems to think I have touched that particular area and thus unwantedly launches an app, or unwantedly closes a webpage I was still browsing. It even gets so bad that when I try to unlock the tablet while charging it jumps to the camera app unlock and takes a bunch of pictures. Now, the weird thing about this is that it only happens on my tablet; my sister's tablet (as I mentioned earlier, exactly the same) does not have this problem with either her or my charger. My tablet does have it no matter which charger is used.
I have already looked for a solution on your forums, but have not found a sufficient solution. Some people did provide a solution in the form of 1. Reflashing my firmware, or 2. Installing a custom ROM. I would like to know which solution you can provide for me. It could also be that the touchscreen is simply damaged; I would then like to send in my tablet for repairs.
If any of you would be able to help me, or have had a similar issue (and preferably fixed it), that would be great. Thanks in advance!

Guys, first of all great forum, excellect tools (like entons rootkit for A71 acer tablet) and splendid advices on many problems. I´m confident to find one for my current problem. If this is the wrong thread, please excuse but I haven´t found one for the Acer A71, so I went to the Android-Thread.
Okay, here´s what happened: I have a rooted (Entons rootkit) A71. Worked perfect for month now. Yesterday I unplugges it after charging. When I switched it on, the screen showed inverted colours. When I try to look at a picture or to watch a video, everything is inerted, too. . I allready unrooted it, made a factory reset, wiped the cache. I have digged into tons of threads in different forums. All that I have found was, that there is a switch you can find in accessability for changing from inverted to normal and back. But this one I do not find on my tablet. I ´m desperate now since I use my tablet for reading (which is still possible), for typing (which is no longer possible) and for videos (which is not longer possible). What to do now?
Datas: Acer iconia B1-A71, Android 4.1.2, Build Acer_AV051_B1-A71_1.25800_WW_GEN1, Image:Acer_AV051_B1-A71_RV05RC05_WW_GEN1, Image-P/N: FM.NLCAO.01Y, Kernel 3.4.0
Would be greatful for any answer.
Thanks a lot in advance.
I have just received this same tablet to repair with the same problem.
Mine would seem to have a damaged screen as its even inverted when in Recovery mode.
Maybe this is the same with you?
A quick google shows a handful of people with the same problem.
The device has some really poor design with the ribbon that connects the screen as some components rest against the quite flexible back cover.
So either one of these tiny components has been damaged or the device dropped and the screen has actually cracked along one of the edges.
What a pity the "invert colors" option is not enabled in the settings app as manually inverted images display fine.
If this was a high end device i'd unlock it and install a custom ROM and have a look into enabling colour inversion somehow but alas i'm not sure this little sucker is worth my time especially as the battery is on its way out now too.
Good Luck.
[EDIT] SOLUTION; it would seem my hunch regarding the crap placement of components on the screens ribbon cable was accurate.
Just found this page: http://forum.xda-developers.com/showpost.php?p=56422766&postcount=220

It works!
Normskilight thank you very much. It works perfectly!!. I could fix my tablet. For my it was a kind of miracle, jaja.
Thank you again!
Hello there.
I'm having problems with my Android device and I'm very frustrated with it so far...
My device is a Motorola Moto G. I've updated it to the latest Android version available (4.4.2), however, I'm experiencing some serious problems; the most important atm is the alarm.
I am using the volume button to snooze the alarm, because imho it's more convenient. However, yesterday the volume button just didn't work for some reason. I had to unlock the screen for it to work, then it started working again with the screen locked. Today the same thing happened, I had to unlock the screen to snooze the alarm using the volume button, then I could snooze it again without unlocking, however, it just 'stopped' by itself, I don't know if the volume button somehow turned the alarm off. I didn't even touch the screen, so it's a bug or something. I've always been using a cell/smartphone to wake up and never had any problem.
Also, this device freezes a lot and I've never experienced that before in any cell/smartphone. It also seems the device must be turned on for the alarm to work; it's not that important for me, but still a 'downgrade' from my previous device. Another thing that really annoys me is that you can't even change the volume without playing the sounds... if you want to set a very loud volume in the middle of the night there's no way other than waking everybody up. Additionally, I would like to be able to somehow record a call, but none of the apps works with this device.
I don't think the alarm problem is a hardware fail or defective device, it seems to me the software is somehow bugged. There's no Cyanogenmod for this device yet (mine is dual chip) and even if it were available, It seems some apps doesn't work with it (like Sygic).
I don't know how I should proceed and I apologize in advance if my question is too 'basic' for a developers forum, but I didn't want to post on the other popular 'user' forums because I've seem many threads where the moderators were just talking nonsense proving that they don't even know how to turn on an Android device, including the extreme case of a newbie asking about some permissions who was somewhat 'burned at the stake' by the moderators and veteran members while he was right all the time, so if the moderators and veterans don't have a clue on what's an Android device I'm surely not reliant to post there. On the other hand all the (/most) posts here on XDA Devs always get correct and helpful replies.
I don't know if I should try downgrading the OS to 4.3 or if there's something else I could try. I don't know if it's possible that the latest update was somehow 'badly flashed'. It doesn't seem very likely to me.
Any help is appreciated.
Thank you in advance.

Thank you for your reply,
However, after Googling and contacting motorola, it seems there's no way of downgrading (without rooting the device) .
The alarm problem is getting worse, today for some reason when the alarm was ringing, instead of the alarm screen, the default lock screen appeared, the volume buttons didn't work also, so there was no way to snooze the alarm, I had to turn it off in the configs and get out the bed like 1 hour earlier than usual.
Isn't it possible that the problem is some kind of flashing fail when I've updated the OS? I highly doubt everyone is having this problem... Isn't there a way of reinstalling the OS?
Also, the hardware isn't very good. It seems of good quality in appearance but after only a couple of months the battery isn't lasting as it used to. motorola support is simply horrendous in my country, there's no support at all. I don't even know why there's a warranty if in practice that means absolutely nothing.
I'm thinking about buying an alarm clock, preferably a german-made one that I can trust... It's outrageous though. I never thought I would need an alarm clock again.
Worst purchase ever. I'm thinking about getting back my cheapo Samsung Galaxy Pocket Plus that I gave away. It wasn't as comfortable as this motorola but it surely did work and the apps were much better, I thought they were all standard Android apps but it ended up they are from Samsung, in 99% of the cases you can long hold the stuff to pop a menu of actions, for example, hold a contact for a menu on editing/deleting/etc. hold a number on a message for a menu on adding-contact/adding-number-to-contact/etc. It was very intuitive and straightforward. The apps in this motorola are exactly the opposite, holding the finger on stuff never do anything and most times not even tapping stuff does anything. It's a pain to use its cumbersome and confusing interface. Only for adding a simple contact I take more than 10 times the time I've used to take to add a contact on my cheapo Samsung phone.
I thought the phone would be good specially in terms of software because motorola is "a Google company" but I was completely wrong. It seems Google is going to sell motorola, perhaps not even they were believing the products were good after all. In any case, I'm never buying motorola again.
Also, there are lots of topics on the poor quality/limitations of stock Android apps and the unanimous solution is to install better apps from Google Play, in the end it's quite a mess because most/some stock apps can't be disabled and their services will continue to run, along with some others from 3rd party that should in fact substitute them. If the stock apps are so poor, there should be a way to completely disable them all imho, or even better, perhaps they could just ship high-quality opensource apps instead of the terrible stock ones.
So far I'm very frustrated. If I could get my money back I would surely get a Blackberry or Samsung device. I don't really care about games and it seems that's what made android so popular, the cornucopia of awful (seriously, 99% of the games on Google Play are of extremely bad quality) games full of sneaky ads and that needs every permission possible to run. That permission thing is another one that doesn't really works. It should work but most apps ask for a lot of permissions that doesn't make any sense and the users don't seem to care much.
Sorry for the rant, thanks for your help.
Hello there.
I'm just posting here to let you know that I've unlocked the bootloader, downgraded to 4.3 and now the thing works perfectly. Plus I've discovered the battery problem AND a poor signal AND cal recording not working were because of the faulty update also! I must inform also that it seems the problem only occurs in dual chip versions and I've already downgraded the system for a friend of mine who was having the same problems, so, if you have the dual chip version, please don't upgrade it to kitkat! You'll get a nonworking OS and will be forced to ditch your warranty to use your phone in a sane way again. It seems the support for the dual chip version was dropped already because the single chip one (which was usable after the update) have received other updates after 4.4 to fix minor bugs, but the dual chip which is totally broken and unusable didn't receive any.
Having to circumvent the normal conditions and lose your warranty to have an usable device proves that motorola (and google by consequence) have the responsibility of a kid.
The downgrade didn't fix the problem with browsing files from the computer though, for that specific problem I'm going to open another thread as it seems android related.
In general the Android community is not very good, it's full of what I suppose are kids, wanting to help but only disrupting any chance to solve the issue. The IRC channel is specially unhelpful. Unless your question is "where do I plug the other end of the cable" or "how do I turn on my device" chances are you won't get any actual help and by the answers you can see the people there don't have a clue on anything. Probably it's full of <10yo kids. At least in mental terms . The XDA however, seems to be an exception, actually standing out from the lots of unhelpful forums and chats out there. In this topic I didn't receive many replies, but it's better this than receiving a lot of moronic replies like I would have received in IRC or other forums.
Thank you.
For lack of a better place to put this, I decided the Android Q/A was probably best. Anyway I'll get straight to the point. I'm attempting to create an HMD using an old Android phone. The problem is, even on a local network, all of the possible Remote Desktop apps seem to have unbearable lag. I cannot fix my network. I'm using Powerline Adapters. I put a WiFi router directly in the room I want to use the phone as an HMD and I've got a direct connection to the main router via Powerline on my PC. It's really as good as it's going to get. And yet I have noticeable lag even just moving my mouse around. So I don't really want suggestions on how to get wireless working better.
What I really want is a true one to one display. Almost like the phone is acting as a secondary monitor to my PC. So whatever my PC is displaying, my android shows with zero lag. That means directly connecting the device I'd imagine. The problem is, EVERY single possible way of wording this in my research seems to provide the exact opposite results of what I'm looking for. Google loves doing that to me. I say "Use Android as PC Monitor" and I get "How to display your Android on your PC monitor". That's just one example of the many different ways I got those same exact results.
So anyway, I would appreciate any direction someone could give me to figure this out. Thanks.
As an update, I just wanted to say I've found two apps that seem to do what I want, but they seem a little iffy. The first Twomon USB - USB Monitor, claims it does precisely what I want. However, the reviews are mixed with some saying it doesn't work. I'd rather not spend almost $10 on something iffy. I'd rather read things like "It connected with no problems and there's NO LAG."
Then the other one is ExtDisplay extend via Wifi/USB. This time it has a free version ExtDisplay Extend PC Display, but I hesitate to try it because of it doesn't have good reviews. I guess I'll try it and come back to this, but I just figured I'd give a little more details on what I'm looking for. These apps claim to be exactly what I'm looking for. Just don't seem to deliver.
How did it go ?

I ended up switching over to a program I'm sure all have heard by now. Trinus Gyre. Well now it's called TrinusVR. At any rate, it worked very well for a while, but my android phone's display is terrible. Trying to play anything is extremely pixelated to the point that I can't read text. I have however been looking out for a program with the same functionality for my iPhone because it has a much higher resolution. I did find one called KinoConsole. It works great and while currently I will use it from time to time for movies, I still can't really use it for gaming because again, text isn't easy to read. At this point I'm just holding out for a professional headset that won't break the bank. I kinda have my heart set on PlaystationVR because of the specs, but still don't know how much they're going to try to sell this thing for.
But, if you're still set on using an Android device, definitely try out TrinusVR. It's worth the money especially if you have a decent resolution.
Folks,
I'm not sure if this issue occurred during 4.4 Kit-kat, but it definitely has happened on Lollipop.
I purchased a 612 in Japan a few months ago. The Lollipop update wasn't coming through for me (and I had some Wi-Fi frequency issues), so when I finally saw an apparently official 612 American (I'm American) ROM to flash, I diligently followed instructions and successfully installed 5.0. I've since upgraded to 5.1.1 using Sony's PC Companion.
Anyways, onto the issue, which I believe this is the ONLY community on the net that could possibly help me with.
In Netflix, and seemingly ONLY on Netflix (as in, not via the Videos app, YouTube, etc), when a movie has high speed panning/action, there is a tear in the first 1/3 of the screen (a vertical one), toward the SONY logo. When I flip the tablet 180 degrees, it's on the opposite 1/3 of the screen!
The ONLY thought I have is that maybe the Japanese models physically have a different refresh rate than the US ones, and in flashing my unit, I managed to run into that issue? And perhaps Netflix is one app that doesn't VSYNC properly? I've tested every thing under the sun and while I originally thought it was happening only after I pulled the notifications tab down from the top, I recently had it happen without touching anything after a fresh restart.
I LOVE this tablet, but honestly, Netflix in bed is a HUGE use case for me. I'd LOVE to solve this issue. If anyone can help (and please let me know if more info is needed btw), I'm exceedingly grateful.
Just noticed the same thing on my UK sgp612 running lollipop. Dud you find any solution?
Hi people, sorry if my english is not good.
Hi, thanks for reply me (and sorry if my english is not good)
The problem is LIKE this:
youtube.com/watch?v=iMnaUsH_Wfg
I went where i bought the mobile to repair it and they said "now all is OK, We change the display". But when I was come back to my home, the problem start again.
I come back to the shop again and they change me for other mobile but the same model.
3 hours all was perfect, but then, has started the problem again with the new mobile!!.
I read a lot of posts in Internet but i don't have any solution.
Someone can help me??
Thanks for all!!
Hello, I've tried in vain to get rid of this horrible flicker by flashing various ROMs. Sometimes it helped for a while, but the flicker always came back. Zopo seems to completely ignore this issue. So better don't expect to get a solution for this device ever. As PWM-dimmed monitors and TVs have become standard, unfortunately, it also seems to me that many people have become unresponsive (or rather dull) to this dramatically technical aberration, so the complaints are rather limited. At least some PC monitor vendors like BenQ have become aware of this impairment and offer flicker-free monitors (DC-dimmed instead of PWM). But, actually, PWM doesn't seem to be the issue here...?! I've tested with my DSLR and there are no PWM-typical hard light on-off cuts. Regardless of that, the flicker is visible and is more than disturbing. I've now switched to a flawless Moto G4 Play and will never ever buy any of Zopo's junk.
