My criteria for a good Tablet
Monday 09th of July 2012
My criteria for a good Tablet, 7/7/2012:Must have:Android 4.0.3 or newer pre-installed.Google Play pre-installed by Manufacturer.Run latest Netflix downloaded from Google Play, not some hacked-up version of Netflix.Be easily root-able, not a 50-step process to hack and root.Have USB driver available from Manufacturer to allow Android SDK to access it as a device.Pass a significantly high percentage of Google's CTS tests.History of Manufacturer delivering software update(s) to customers, via their website.Android standard screenshot works (Power + Volume-down ?).Easy to get into stock recovery via key-combination on boot.English docs that are available and accurate.ClockWork Mod Recovery available, to allow nandroid backups.Nice to have:Large user base.Good support from Manufacturer.Device charging via USB port as well as power adapter.Not too expensive (subjective).Removable micro-SD card.7" size.Easy and inexpensive product return process (i.e. none of that $100 return-shipping cost BS).Nexus 7 tablet is pretty close. Any other tablet meet all of the above criteria?
Can USB charging (via mains adapter or from PC/Mac) of Android tablets be the main, primary method of charging? Or are there design issues?

Are there design issues with tablets being charged by USB not seen with Android phones?I saw this on another forum, what are your thoughts on this with regard to my question?http://forums.androidcentral.com/acer-iconia-a100/112270-charge-via-usb-port.html#post1696260 An important consideration in the design is the amount of current the usb connectors can handle. I figure the designers find that it is safer to design a separate charging and power connector because as the devices get larger they draw more current to operate and charge the battery. I think that is the reason they do that. Is there no 12 volt adapter for these devices? I don't own one yet, just leaning towards the acer 7 inch tablet.I would prefer charging via USB (via mains or PC) when considering a tablet so that I don't have to carry around a specific charger.Many Android phones use their micro USB port for charging - connecting the USB cable to a mains adapter or using the cable to connect to a full size USB port on a computer.I see that some major brand Android tablet manufacturers (Motorola, Asus) as well as some

I have an android cell phone, well its more like a cellphone/tablet. I was charging it via usb cord to computer and it shut off while charging. Now the device does not come on at all or will no longer charge through usb or wall charger. I have tried everything but the device still will not turn back on or charge at all. What may have caused this to happen and is it fixable?Already Tried: I have tried charging the phone with both usb charger and wall charger. Tried re-booting phone according to seller instructions. Looking for a repair place to take it to.
Charging tablet via USB
Monday 04th of June 2012
I just noticed my tablet charges slowly when connected via USB to a PC: it went from 15% to 80% in about 2 hours, even though it says "Not charging".I am quite happy about this because many people have said that tablets cannot be charged via USB and need the power adapter.See attached images:

Dear PeepsI brought my girlfriend a U30GT after reading so many good reviews from Android Tablet | Android Tablet PC | The Best Google Android Tablet UK Online Store and wanted to know if anyone had had the same experience, or could help me with my issues. I was told that they had the tablet ready to ship from inside the UK, mine was sent from China. They said that no extra taxes would be incurred, I had to pay extra to recieve it. I emailed them about it, but had no answer. So far, I wasn't overly concerned. After having very light use for 3 weeks (the protective wrapper is still on the tablet) the U30GT has stopped working. It just wont turn on. I've seen that a lot of people have had similar issues and perhaps it's the power cord. I've tried charging it via USB, plugging it into the PC to see if it recognises it's presence, but nothing. So I've contacted Android Tablet | Android Tablet PC | The Best Google Android Tablet UK Online Store via all means possible and still haven't heard anything back. Has anyone managed to get a hold of these guys in a similar situation? Such a shame

I am using the USB adapter, and this used to work on my galaxy note as of Tuesday.Tablet does not charge the battery via AC adapter or PC USB when the tablet is on. A red X Mark shows up over the battery indicator. Tablet will charge if it is turned offComputer makes the USB device connected noise, but says USB device not recognizedTablet recognizes that the USB adapter is connected, but not the dslr camera when the camera is plugged into the USB adapter. USB adapter: Galaxy TabTM Adapter (USB) (remove 10.1) and as I mentioned before, if I plug everything into the other tablet it recognizes the camera (usb device) immediately*although this is the galaxy notes and not the galaxy tab, all of the hardware in connections seem to be the same. Wall chargers are exactly the same, and the USB adapter works on both. Or at least it did until TuesdayWhat is not the problem:USB wire, charger – I am using the stock Samsung USB wire and wall charger. It

I've been having problems with connecting my TF101 ICS v 4.0.3 to my computer via USB. I've been using the charger cable and I have not been able to have the PC even recognize or see the tablet. I've tried all 8 of my USB ports on my PC and NONE have worked. I've also tried using a old Windows computer, a Window 7 labtop, and a Ubuntu. None have worked. My USB 3.0 cable works with charging my tablet. I was able to connect my Tablet to my PC without any problems before the ICS update, but now I am COMPLETELY unable to even remotely connect my tablet to my PC. I am running Win 7 Home Premium.I have tried:Different USB portsDifferent PC'sInstalling the ASUS_Android_USB_Drivers.zip (Even though you're suppose to use it to update the TF101's drivers AFTER your PC has detected the tablet.)Turning MBT off then onTurning on and off USB debuggingPlease help me, I've been trying to connect my tablet to my PC since last year in May.

New Tablet New Issue, Galaxy Tab S 10.5
Wednesday 18th of February 2015
I just purchased my tablet and received it yesterday. It had 20% battery life. I downloaded a few apps to start it all off, then after it had about 10% battery left I put it on the charger and let it do it's thing for about 4 hours. Ever since then it rarely gives me the battery with the lighting bolt, signifying it is charging with the 0% battery icon afterwards. I am charging it with the Samsung OEM charger to no avail. I've left it on the charger for 10+ hours and still nothing. Plugged it into my computer and it doesn't register as a USB device. What do I do next? Hopefully I didn't spend $400 on a busted tablet... In the mean time, I'll let it "charge" via USB from my computer while I'm at work. Heard the "trickle charge" may be what it needs.
