Which Android tablets have an NFC reader on the FRONT (screen) side? - NFC Hacking

Hello all, I found a thread on stackoverflow which turned me on to getting a used Nexus 10. All was great, until it turns out the Nexus 10 drains battery faster than it charges when the screen is on / in use, making it useless for my application as the screen needs to stay on.
Does anyone know of any other Android *tablets* that have the NFC reader on the FRONT (screen) side? Thanks in advance!

Now that you had the A100 for a while any problems

Now that I have had this tab for a month. Its now starting to act up. Browser force closing, touch screen can be difficult to navigate (too sensitive) it will often open apps when swiping through screens, and overall performance is getting really slow. I have added a memory card to free up some memory but doesn't help. So I'm wondering what the community experience for us that has had the device for awhile.

I really like my A100 overall. Three things that are starting to kill me about it are:
1: Battery life; I've attempted to remove all/some/certain apps, turn off syncing, set sync long, turn wifi/gps off, remove "bloat", turn screen brightness low etc.. For the last two weeks I've tried a lot of different methods to save battery. Still, last night I went to sleep with it at 60-70%(on my latest method to save battery) and woke up with it completely drained. Might need to exchange it I guess.
2: Viewing angles. Thought I could deal with it no problem. However, when I use it as an e-reader (or anytime is portrait) the viewing angles make it difficult to look at the screen for extended periods of time. I have to tilt the left side back more so I don't strain my eyes.
3: Live wallpapers; Many are unusable. I have 4 widgets total and only use 3 home screens. On many of the live wallpapers I use, the swiping of screens either is very laggy, or has a very obvious delay in the time I swipe to the time the screen actually moves.
Performance has started to get slightly worse, not too bad though. I have started to get force closes on some apps and the browser. May end up returning / selling this and get something else. Pity, I really like it other than the first two annoyances..I can live without live wallpaper.
Battery life is a sore point for me as I'm sure it is for everyone. The screen isn't great, but it's not bad enough to bother me much.
I haven't had any software problems fortunately, or at least not any that aren't common with the whole Honeycomb live beta that Google has been running all year. Hopefully ICS will fix a lot on the software side.
That being said, I'm coming from a Nook Color(with a Kindle Fire also considered). Since I paid in the same price range for this($189 on Black Friday) the trade offs as compared to the Nook/KF aren't too bad and at the end of the day I do like having a full tablet with out having to turn it into an ugly hack job(I'm especially looking at you Nook Color)
For $200, I'd say I got my moneys worth, and I might even say it's worth it for the $260 BestBuy is still selling them for, but anything higher, and I'd say it'd be too much to pay for this thing. It's not a high quality tablet, the screen and battery life seal the deal on that one, but it's definitely not the worst tablet I've seen out there. It's miles better than all the cheap Chinese crap tablets, but it doesn't to much to exceed the standards of the "upper crap" brands like Archos.
I'd say the thing is worth about $250.
For now, I think 7" is the sweet spot for tablets. (I previously owned a 10.1" Asus Transformer, which had great battery life and a beautiful screen but was awkwardly big/heavy).
And that said, the A100 is the best 7" tablet currently available (including the new 7" Galaxy Tab, simply because it lacks a microSD slot. I wouldn't trade my microSD slot for 3 more hours of battery life and an IPS screen, especially if the deal added $100+ bucks to the price.)
- I give the screen a B+ (I do wish it didn't solarize from the bottom viewing angle, but it's otherwise bright and clear.)
- Real world battery life, C+ (6 hours is fine enough in practice because I charge nightly, but it'd be awesome to have 12 hours--save me from bringing the charger on short trips, etc.)
- The industrial design I don't care at all about. I have it in the phenomenal Blurex leather case, so the lame blue plastic/silver swirl thing on the back is a non-issue to me.
Really, Acer made all the right compromises. My next tablet will probably be the Transformer 3 when it comes out in a year, hopefully it'll have 300 ppi screen and will dual boot Jelly Bean and Windows 8. If Windows developers embrace ARM , I think a Transformer 3 + laptop dock will mean I'll never buy another PC.
Until tablets can replace laptops (early 2013), a cheap but fullspeed 7" is a great device.
I've had mine for about 2 weeks and I have seen some slowdown when booting up and scrolling in the app drawer from time to time but most likely due to having installed so many apps. Battery has been better for me. I have my wifi to turn off when screen is off and also have a wifi toggle widget to turn off wifi when I'm playing a game or sometimes I just turn off wifi completely when I'm not using the tablet which only drains my battery about 1-2% per hour. Overall usage I would say I get the normal 5 hour mark. Viewing angle is not much an issue for me as I always look at the tablet straight on and its much sharper than my older Samsung tab 7. The only issue I still have is the screen not being responsive or some are saying too sensitive. There's a thread on this already. I'm hoping this will be fixed via software. This is my 3rd one however since my other 2 had wifi issues. I fixed one but it still had screen touch issue so I exchanged and all 3 was the same. So far I'm happy for the $248 I purchased it for. I bring this thing everywhere i go since it fits inside my jacket pocket.
Mainly battery life is the sore point for me.
The screen is more sensitive than my iDevices but nowhere as bad as my LG Evo phone was. A bit more sensitive than the Blackberry Playbook.
Disabling the capacitive home button was a must for me. I would hit it so many times when holding it in landscape view, it drove me crazy.
The screen, I agree with everyone else about the viewing angle from the bottom not being good.
Of course, there is always room for improvement. The hardware in the PB is great, especially the screen and battery life but the software is way lacking in comparison to Android.
At $250, it is a good tablet. I wouldn't pay more for it than that.
It's the perfect size and I take it almost everywhere.

I bought one.for my daughter and have been playing with it for 2 weeks now..Rooted it as soon as.I took it out of the box and installed a few root apps like ad free to keep her from clicking on ads.
For $250 I have to say I am pretty impressed. I have loaded it up with a bunch of educational apps as well as games. So far I have not had one force close on any app. Battery life is ok and WiFi is fastest device off same router as my dinc and t60.
I am not sure what you guys expect for 250, but if you can find any Android device that doesn't need.to be charged daily, then you aren't using it.
Just my opinion

My thoughts exactly for the price it cant be beat. Very happy with the purchase. here is a screen cap of my a100 i never turn off wifi, this was with light usage. with regular use gaming/browsing for me I still get 8hrs.
For personal use the A100 is the perfect tablet, it easily fits in the inside pocket of a jacket, and despite complaints from others that the screen and battery life is not ideal, I think the screen is adequate and after 7 weeks I once had an empty battery. It is complete with Android 3.2, HDMI (works great as HTPC), 3.5mm audio connector, GPS, dual camera (not its strongest point), micro USB slave (missing USB host), Micro SD slot, and replacable battery. Upgrade to ICS is available next month. Moreover, it is much more affordable as similar products from its competitors.
Has anyone tried to use the tablet with it lying on any surface. Recently i discovered that with it on a bed or table lying flat the touch screen is practically unusable. Using a stylus for note taking is useless, it doesn't register every stroke and writing is broken up.

Yeah the touchscreen has some issues. If you lightly swipe the touchscreen on the browser it will zoom in I dunno why
@qhinton:
If you must use the A100 while it's lying on a table or a bed, try turning it upside-down first. There is no backlight on the bottom edge, only on the top edge. Viewing from above the top edge, or flipping the A100 upside down and viewing from below, is much better that way. Not perfect, but better.
Another remedy is to get an easel case, so you can prop the A100 at a comfortable viewing angle.

Thanks I found that trick out from using a Viewsonic GTab. What I was explaining is that the tablet needs to be grounded to work properly. So basically if your not holding it the tablet struggles with registering your gestures. Whem laying it on a bed or table the tablet touch screen would be very sporadic.

If you have major sensitivity issues try my fix posted here:
http://forum.xda-developers.com/showthread.php?t=1347123&page=6
This has mostly fixed the issue for me, still shows up every once in a while but after doing this fix there was a huge improvement for me.
WiFi keeps turning itself off every few minutes. checked all the settings and it still does it. none of my other Android devices do this, only the Tab 7"
after two months of use.
I'm very satisfied of this tab. No "problem" at all.
Battery life: is good if used well. Obviously could be better, but with a double core and a so large display is very good. It surprises me when i play HD games for long and i see almost no change in battery life.
Wifi: signal reception is good, no problem. Connection speed at my home is almost 1Mb/sec checked on tablet.
Display and touch: angle of sight is small for a tablet, but colors and luminosity is very good. Touch screen is very very sensible but i like it. With the screen saver the touch is perfect.
Performance: I'm agree with my colleagues about the live wallpaper. Sometimes they are too slow. The computing speed of this tab is very very good. Opening apps, photos and hd video is vey fast. It's definitely a fast tab
Camera: Is good enough. I've recently bought a Galaxy S 2 with a 8mp camera and I see the difference from the 5mpx of the A100 but is still capable of very high detailed photos.
Voip and VideoCalls: I use this two features a lot since I'm often away from home and both are very good. No lag at all. Video is clear and fluid, audio too. The microphone volume is low I think, but is not a problem if you can hold it closer to you.
Handling and Style: I can bring it inside a pocket and go wherever I want. Is not heavy, it doesn't need a separate bag to be kept with you. Is the perfect size in terms of mobility. The shape is cool and can be handled easily. Maybe the back of the cover would be better completely gray or black.
No problem apart from the fact that i cannot delete bloat cuz i dunno which system app will brick if i delete em, weight since i hold it in portrait mode often, FCs, lastly screen ratio. Prefer it wider and shorter.

If you mess up you should be able to just flash any of the update.zip in the rom thread to bring those files back. You will need to reroot if were already rooted.

[App Req] Proximity Sensor Screen Off for Flip Covers

hey guys!
I am using a flip cover from Rock for HOX. I love the app called Smartcover which let's me use my cover just like the smart cover of ipad using the proximity sensors.. but, I am getting a feel that it drains my battery like anything..
now, I wanna know if someone can suggest an app which is low on battery drain for using this amazing function.. Also, wanna know other's take on the battery performance using this app..
Hi there! You could try Proximity Screen Off from Google play. I had it and it didn't seem to eat lots of power.

If you have a look at the permissions required for that application you can see it has permissions to keep your phone awake.
The proximity sensor is off when the phone is in standby, I suspect this is a hardware limitation, i.e. the proximity sensor isn't it's own independent hardware device but is partly software driven and requires the phone on to work.
For your application to work, it has to stop the phone sleeping in order to get a readout from the proximity sensor, and so your battery goes flat quicker.
I doubt there is any application that can change this behaviour as that is how the proximity sensor works, it needs the phone on.
Regards
Phil

I tried using this app.. this helps in switching the screen off but it wont switch the screen on once I flip the cover.. so doesn't work exactly how I wanted..
while browsing through XDA, i found that ppl have developed apps for the same purpose & those are really battery drain free.. so was wondering if the same was possible with HOX too...

I use Smart Screen Off, you may try it. Prefer over Proximity Screen Off. It don't lock the screen if you have security lock on.

[Q] What's the main reason for you to choose the Sony Smartwatch 3?

In my case,
1. Battery life: I wake up at 6 and go to bed at midnight. The bigger battery, and the transreflective display gives me some peace of mind that I'll not worry that my smartwatch will die when I need it. Also, love the idea of monitoring my sleep and setting an alarm to wake me up at the ideal time (instead of being in the table recharging).
2. Square display: Although round watch faces look classy, I don't like the idea of wasting screen real state for a fancier look.
3. Android Wear: Definitely Google got it right (Unlike Samsung or Apple). A smartwatch complements the smartphone (not replace its features). Simplicity to dismiss discretely notifications, or get directions while using the smartphone for other purpose, or keeping it in your pocket whithout the hassle of picking it up every time I get another notification.
4. Display: As an Ingress player, I'm frequently outside. Sunlight can make most screens difficult to read, or waste too much energy to give maximum luminosity. Transreflective display uses the ambient light, making it perfectly readable at direct sun light and saving energy.
My reason is the mix of fitness watch for running + multimedia (music) without the phone. If that is a BIG YES, all the other features for the rest of the day are welcome but not the main reason to wear it.
For me it would be:
The builtin GPS: ability to hace mapa on the watch even without a phone, or with the phone in a bag or somewhere else with poor reception
Reflective LCD: The benefits of a color screen without the disadvantages of a backlighted one (e.g. no always on, too-bright in the dark, etc.)
microUSB port: no stupid dock that breaks/get lost easily, no proprietary magnetic charging, no fiddling required to get a USB console.

[Q] S-pen switch fell out, always showing as detached

Hi all, had to disconnect the battery on my Note 8 to fix the drain problem.
After putting the case back on and seeing a great improvement I also see the s-pen shows as detached even when it's in.
Opened it up again and a small leaf switch has fallen out can anyone tell me / share a picture showing where it goes.
Thanks

Moto X like Ambient display?

I have a Moto X 2013. It doesn't have all the fancy features of the Moto X (2014) or even the Nexus 6, but I believe it made use of its sole proximity sensor to perform a really slick implementation of Moto Display. It used the proximity sensor to identify when you are picking up the phone or when your hand is close to the phone and accordingly show the time on the screen. It also pulsated the notification on screen when there was a notification. Very responsive and efficient. Is there some app that can emulate this for the Nexus 5X? Why not use the Nexus's proximity sensor all the time like the Moto X to identify when we are picking up the phone? What is the limitation here?

since Moto X 2013 used an Amoled display. It could turn on few pixels on the screen to show you pulsated notifications and not drain the battery or heat up the device, Nexus 5x unfortunately uses a LCD screen so turning on few pixels on the screen is out of the question even if someone force the feature onto N5X it'll led to Huge battery drain + Heat up so in short ITS NOT POSSIBLE.

The 2015 Moto X has a LCD display and functions just as the 2013 Moto X did with an AMOLED display. The '15 didn't heat up and the battery drain wasn't as bad as you would think. However, the whole display turning on was annoying and one of the reasons I turned Moto Display off and eventually sold the phone.
I wasn't even talking about '15 version. Though you answered it yourself.

That does not answer my question. I am fully aware that due to the LCD screen, it cannot just turn on some pixels. But, what I want is an app that can use the proximity sensor to identify when we are using the phone or picking up the phone and then turn the screen on for displaying the notification. That should be doable right?

You suggested that the 5X would heat up and it would kill the battery because of the screen tech. You are wrong. The 2015 moto x is the proof. RIF, princess.

You might want to take a look at Gravity Screen, from the Play Store.
I use Dynamic Notifications on my old GNex that I have lying around. It works pretty much like the moto x's active display. There are options to have it sense when its pulled out of your pocket or picked up off a table, but I don't remember if those are only in the full version or the free one as well.

Thanks, I tried it and seems to work. But also, it seems to be a little aggressive with the turning the display off thing that my display seems to turn off very very quickly even when I am using it.

@PiousInquisitor I assume you haven't tried Tap2wake feature on ElementalX ? It eats alot of battery life hence heating up my device not that much but still. Do your research before you reply kid
BTW With Moto X 2014 there is something with the Display that doesn't cause it to heat up. Just like on G2,G3,G4.

Tap to wake and Moto Display are two different things, tiger. Try again.

Is Ambient display like on stock marshmallow what you want then?
Lights up the screen in a sort of monochrome to display time/notifications only on lock screen when you pick up the phone.
"AC display" app is a great substitute for moto display. Combined with double tap2wake when phone is out of pocket and you're all set.

It does not eat *a lot* of battery, just a tiny bit. And does not heat your device at all.
