I purchased a ICOO D70 Pro II. Ordered on March/1, shipped Mar/8, and arrived Mon Mar/18.

Bought this since it was pretty inexpensive - but seemed to get good benchmark scores
and as this was my first tablet - I thought I stay low priced - to see what I may or may not like about them
Since I have an Android phone I was relatively familiar with the tablet operation. The main difference for me was the on screen "soft" keys/icons for Home, Return and Menu which are hard keys on my phone - sometimes some apps take the full screen and those soft keys are not shown - I haven't found out how to get them to show yet.....

Version -


Size:
I do like the size - I know 10" tablets are far more popular - but this 7" tablet fits my needs fine - even if it is only around the house - the size is right.

Screen and Viewing Angles:
Then there is the screen - straight on it is fine - a bit garish in colors as I normally work on an sRGB space AH-IPS monitor and here the tablet colors are overly saturated - well garish, is probably the best word.

Then there is the viewing angle - not horrible - but "bothersome" - held in the hand one can vary/tilt the angle to get good view - but say placing on some variable surface like cushion/couch etc. and the tablet can move, then the viewing isn't that great - then the very prevalent black background screens sometimes makes viewing difficult - in some ways I sort of wish I got an IPS screen, where this probably would not be a problem. But then again I only saw ips tablets at about 50% more in cost than this cheapo (* see later) - so not really "regretting", but more "longing". My phone (LG Optimus T) probably is IPS because its viewing angles are a lot better than this tablet.

I figured out a partial reason for my viewing angle difficulties - I usually use the tablet in landscape orientation - but find it difficult to view if I just put it on a surface like on the seat next to me - I seem to have to hunch over the screen to get a more or less straight on view - hence my "complaint" - this is somewhat mitigated if handheld - where I would just adjust the angle to suit.

However after having this for a few days I thought the view from the other side of the tablet seemed better - this was almost revelationary.

I had been using the tablet with what I thought the obvious orientation with the On/Off switch and volume control along the top edge - the volume control would be + to the right and - to the left.

However flipping the tablet around so that the switches were on the bottom gave much better angles - I know it seems obvious now that the orientation would make a difference - just didn't figure it until a few days later.... so how much difference? I used the bubble level on Swiss Army Knife app - then viewed directly over the screen then tilted the tablet to see the angles where the view would still be acceptable - I'm sure this is not definitive - but close enough for me:


This shows why I was having problems with the screen. Now having the edge with the switches along the bottom has improved the viewing by quite a bit.

The viewing angles when the tablet is in portrait mode is better, I can almost believe the specs of 150º. Of course any tilting side to side would still result in poorer viewing - but this is fairly unlikely when held in the portrait mode. Initially I thought perhaps they had mounted the screen "upside down" as far as the landscape mode was concerned - BUT if one were to prop the tablet up on a stand or keyboard case - then the screen orientation does make sense as we are more likely to view it a little more from the above.

So for casual landscape mode handheld, or simply putting it horizontally on the surface on table/chair/couch/bed - then I feel it's better to have the tablet with the switch edge at the bottom. But on a stand tilted then probably better with the switch edge along the top....

Portrait/vertical mode doesn't make much difference whether the switches are to the left or right - except if the tendency is to tilt it more to the right then have switches on left (and vice versa)

7" screen and 1024x600px are more than adequate for most of my browsing. I'm not too sure if I'd want to go as low as 800x480px - I think 1280x800px IPS would look stunning - but not really necessary for my usage - remember the image and text font sizes are going to be the same - just more pixels packed into the same size area - but IPS would still be nice - even if I have now got used to my non-IPS screen - but to hold 1024x600 on a 7" screen is still pretty amazing - my old crt monitor was 1024x768 and that was 15"!!

Apps
The ICOO D70 Pro-II does have Google Play/Store installed and I was able to download most of the apps I thought were useful (my phone experience) a few apps were not compatible - surprisingly like Viber. But other free WiFi calling apps were compatible Groove IP Lite and Talkatone definitely can make phone calls even with my preference of using a headset - so the headphone socket does have the 3 connection for a headset - although in Groove IP Lite the earphone volume seemed a bit low - haven't figured yet whether I was adjusting the correct volume....

Benchmarks -
It is not all negative - the performance is outstanding - Antutu benchmark scores - close, but not quite as fast as the Google Nexus 7 - 12,726 faster than the Acer A110 - 10,606 - this ICOO D70 Pro II clocks in at over 11,000 -

comparison ranking -


Vellamo benchmarks:
HTML5 -


Metal -


This is pretty impressive for a tablet that costs significantly less than half of the Nexus 7

WiFi
WiFi is good - I connected fine in my living room - the gateway/router was in the basement - then even upstairs - one more floor up.

Battery
The battery specs are 3000mAh - from 100% charged to 0% shutdown seems to last barely about 2 hours in use, with sleep/idle it can last over a day:
.




Overall I am quite pleased.

* IPS screen -
Non-IPS screen is for me still the biggest drawback - especially as I have found an IPS tablet with similar specs for just $5+ more. I can live with non-IPS - but wish I knew about the IPS screen tablet -

AMPE A78 7" IPS L-142718

Ampe A78 IPS Antutu score on YouTube = 12,541

Google Translation of Ampe A78 IPS Review Antutu = 12,378; Vellamo HTML5 = 1390; Metal = 499

Seems like about the same performance as this ICOO D70 Pro-II, and like a pretty competent tablet.

Hi UkVT - your name rings a bell - puppylinux? Tinycorelinux?

Good, no, excellent review. The battery is crap, I think below 1000mAh. A fair few have replaced the battery with a 5000mAh. Well worth the effort.

Thank you jured-

Moniker is just unknown VT (latter my initials)

I had a bit of a scare yesterday while charging the tablet -
as my normal practice I allowed the battery to reach shutdown -
then I placed the battery on charge -
all seemed well
the tablet seemed to indicate charging with the initial battery charging icon
after a couple of minutes I was able to boot the tablet -
to the home screen.

I then proceeded to do things like check apps updates etc while charging.

Everything seemed quite normal - then I noticed the charge status notification icon showed 0% while on the charger.
That didn't seem right - so I disconnected the microUSB plug of the charger, and the tablet immediately shutdown.

Plugged the microUSB of charger back in and instead of the battery charging icon I got:

this did not look good.
Unplugged the charger from the wall and moved everything to a darkened room so I could take the photo above -
the same icon continued.

Figuring perhaps it was the charger or cable - as I was using a different set up -
I unplugged everything and used the known good charger and cable (used for my phone).

Thank goodness after a few minutes - of holding my breath -
the normal initial battery charging icon came up,
and waiting a few more, I was able to boot up the tablet.

Since then things seemed OK.

I did a bit of recording -
battery history showing the time of starting the charge
and when I first unplugged the charger to get that battery problem icon:

12:18PM would be start of charge. About 12:43PM was when I unplugged the charger (as I saw 0% while charger was plugged in)
So from 12:43 to 12:57PM was when that battery problem icon was shown, if I plugged that charger in.

12:57pm was when I plugged in the known good charger and cable. Phew!

Here's the graphical record - it's all toward the right end of the graph:

notice the two sections of 0% toward the right end - with a tiny step up to 2% (as given by the battery history figure) in between.

The tablet was saying between 1:36 to 1:43pm that it was at 0% despite the charger being plugged in and obviously powering the tablet, since I was working on it -
it was only when I noticed the 0% that I unplugged the charger and that's when the battery problem icon showed......

Today, April/3 - the battery seems to be working well and short WiFi usage did not seem to deplete it as quickly as before - it used to be quite alarming how quickly the battery would run down.

Perhaps it's because the battery has had a few full charge/discharge cycles to reach better working capacity.

It appears that using Airplane mode conserves the battery better - even though there is no 3G networking capability on the tablet.

I cannot say definitively - but the battery seems to be lasting better today including some quite intensive usages - like telephony.

Headset/phone Volume -

I have also figured out why the volume in the earpiece was so low,

It was the headphone socket - if headset plug was pushed all the way in - then I'd get low volumes and the receiving end has also complained the voice quality wasn't that good -
but pulling out the headset I noticed a momentary increase in volume
light-bulb
moment!

If the plug was only partially in, the volume was loud! -
since I had adjusted the volumes up in all the phone apps -
quickly turned them back to normal -
I now can easily make free calls using the those apps and get pretty good audio quality

I received my icoo d70pro II two days ago, and I agree that viewing angles and battery life are the main drawbacks, Ive had 3 tablets before (2 ainol´s and 1 "no brand", neither had IPS screen) and the icoo has the worst viewing angles and battery life of all.

I just tried the hdmi out and it doesnt work, the cable works fine because I used it with my previous tablets, Ive tried to change some hdmi settings and used 2 different TVs, but still no image. I might try the darkwater rom because I really need the hdmi out.

I can just manage to live with the viewing angles - although I'm sure that ips screen Ampe A78 would have been better for all of $5+ more.

I think battery life may be improving marginally - of course, this could my optimistic view, or I may have learned to conserve battery better -
it is obviously still no where near great - but just about liveable.

All this may be moot -
and I think my idea of starting with something cheap just to try out - was probably the right move -
since there is very likely to be a Nexus 7 replacement in July and priced either at $149 or at the same $199 (but dropping the price of the current version) - if so, announcement at Google I/O May/15-17.

New Nexus 7 reportedly gets Qualcomm chip, better screen, and lower price

The Nexus 7 has always been my benchmark for 7" tablets - it certainly addresses both issues of better ips screen viewing angles
as well as really good battery life.

Very good review indeed. I just wanted to add that hdmi works for me perfectly, also the earphone plug, i have the same tablet with earlier dated rom (1203).

Battery Life -
I could not find any battery testing apps that would run on this Icoo D70 Pro II tablet - neither Antutu Tester or Nova Battery Tester were compatible with this tablet.

So I devised an ad-hoc test similar to the rating for the Nexus 7 -
played a 720p movie/video (using MX Player) with WiFi On

Running both Battery Monitor Widget and Battery Log in the background to log the battery usage.

I managed a screenshot of the video moments before the tablet shutdown:


shows the time of 3hrs 43mins - with remaining 1% battery charge - WiFi On -
tablet shutdown 3mins later at 1:18.

Both logs agree with each other -
Battery Monitor Widget History -

and
Battery Log -


The graph from Battery Log:


I'll use the battery log figures - 100% at 21:32:40 - started the movie about 1/2 minute later (21:33) - shutdown was about 1:18:19 -
total time on battery = 3hrs 45mins.

This seems pretty respectable, as the load was pretty heavy.

The straight drain seemed promising at 3hours 45mins playing a 720p video (at about 75% brightness) and WiFi On.

Also wanted to record my typical usage. I am now turning the tablet Off at night when I sleep - it seems sometimes there is no drain, others quite high drain and, even an increase in remaining capacity.
Using Battery Monitor Widget (BMW) and Battery Log to record this - but the remaining % levels are basically what Android is reporting.

Battery Log -


Using the BMW figures - Unplugged at 100% charge 4:42am 4/09 - actually turned the tablet Off shortly after (that's why BMW reports 87 records missing)
- notice that when I turned it back On the level was 93%.

Battery Log records differently - logs only at % change so it went from 100% at 4:42am to 94% at 10:39:15am (when I turned the tablet back On) and very quickly to 93% just 4 secs later!

0% shutdown was reached about 8:36am 4/11 - so this is almost 2 days 4hours - but I am pretty miserly with battery - as mentioned even turning the tablet off at night when I sleep.

Android Settings for Battery Usage -

reports a total On time of 1day 10hours -

BMW can show the apps usage too -


After this charge I will leave the tablet on to see total elapsed time - no turning off at night, just the regular Sleep mode.

FWIW - I have read of cases where the Icoo D70 Pro II battery does not seem to get above 4V (4000mV) at end of charge.

Mine has reached above 4100mV from the start -
Only once did it just reach 99% and stayed there -
but that was with a different charger and cable -
since then I have only used the charger and cable for my phone.

Max and min voltage levels:

as reported by BMW -
min: 3490mV
max: 4160mV

Straight battery usage without turning off at night - ie: the Icoo D70 Pro II was On throughout - mostly in sleep/standby mode.

That's from Apr/11 15:42 to Apr/13 21:16 = 2days 5hours 34mins on battery with my miserly usage -
mostly in mornings Wifi On - browser - checking e-mail and weather etc. very light surfing - check Google Play for any updates.
Then occasional phone calls.

Apps battery usage as reported by BMW -


So battery life is not exactly sterling -
but tolerable for my usage -
I can get basically two days between charge (without having to turn off at night)
and a good two full mornings' worth of usage -
and depending on when I have to charge - perhaps even three mornings.

You must've lucked out with that original battery. I don't think I came close to your operating time with mine.

Did you play the 720p video with HW+ ? I'm running a 480p MPG file in HW mode (won't run in HW+) and it's chewing up ~40% CPU.

I'm at 4 hrs playing time with 26% left (I'm using a 5000maH battery).

EDIT: Just finished at 5hrs exactly. I would say with HW+ on an x264 video it might go a bit longer.

I used the Android App: MX Player
This is their blurb:
" a) HARDWARE ACCELERATION - Hardware acceleration can be applied to more videos with the help of new H/W decoder.
b ) MULTI-CORE DECODING - MX Player is the first Android video player which supports multi-core decoding. Test result proved that dual-core device's performance is better up to 70% than that of single-core devices.

Hi,

I have also ICOO D70 Pro II tablet. I think it is a good tablet. Only thing that is bad is when I move finger slowly on screen scrolling is very jerky. When I slowly scroll screen f.e. in browser screen takes big jumps very fast. That is very annoying. Has anyone else noticed this same problem? Is the screen so poor that it can not handle slow scrolling or could this be a software problem? I have tested many other 7" tablets and I haven't noticed same problem.

Hello guys!

I don't have the scrolling bug, but I have 1 cm insensitive zone in the touchscreen (top side, in landscape mode, when the power button is on the top).
As seen on this video from 1:40
I have the same problem..
Is it hardver or software issue? Anybody have the same problem?
In 3 side I have 0.5 cm dead zone and 1 side have 1 cm. The 0.5 cm is ok, but the 1 cm causes problems..
Thank you!
Andrew

Not so good.... A few days ago my Icoo D70 Pro II developed a problem -
a line right across the screen - started off as a blue line - then changed after about 1/2-1 hour to a red line - then a few days later another line appeared this time it's green.
Not just a dead pixel - but a two whole lines of inactive pixels:


It doesn't stop me from using it - but it certainly is not good.

Hello jktla, I am sorry to say that I also have the "scroll bug". In the begining I thought that it was a matter of responsiveness of the tablet, like CPU/display. But now I have compared with other tablets, using touch monitoring tool like z-device test, and one can see that the response of the touch screen is very un-even, like jumping as you said.

I don't know if this is a HW or SW/driver issue. What I can say is that I have stock ROM 20121220.

Good luck!

I also have the D70pro II for about 3 months now.
Ok it is not an iPad but for a little surfing at the couch and things like that it is quit ok.

Unfortunately it does not start up correct no more. It keeps hanging at the "android" writting.
If somebody has an idea how to fix it, just let me know.
The data which is currently at the tabelt is not relevant.

Greetings,
Jo
