[Teclast X98 Air 3G] articsilverfox:
OK I have installed your Lollipop v4 rom, before I was in Mirek190 Kitkat, and have just been installing all my apps from the google play store, everything so far is rocketing along fine.

I will update this post to see if I kill freeze my tablet so far its been working fine.

I am installing Asphalt Airborne 8 at the moment, will have a play and see how it goes...

I will edit this post on the updates....

*UPDATE*.

So far its been really solid.. On my very first boot at first after installing like 30 apps and running them and then finally installing and starting up Asphalt Airborne 8 it came across a little choppy when loading up so I restarted it first thing and it was fine. I recommend you do a reboot after your very first boot and installation of apps etc (this should be a no brainer)

I tested the front and back camera via the Google Camera app and that works fine...

I played Asphalt Airborne 8 for about 30mins and it ran perfectly fine nice smooth and solid...I recon its running faster on this Lollipop ROM then it did on the Kitkat..

Here are some benchmarks.

http://browser.primatelabs.com/geekbench3/3184237

34479 on Untutu, it doesn't make a URL any more in the new app?

I just tried to take a snapshot of my Untutu screen as there is no URL to paste, I actually did kind of make it freeze I think.. I forgot how to take a snap shot so I was hitting the volume up and down and power buttons etc at the same time and the tablet stopped responding to touches, I could still see the Antutu score green circle logo thingy shineing/moving animation but the tablet as a whole wasn't responding to input..

*edit* I worked out how to take screenshots by just clicking on the little icon on the bottom left of the screen....

Update 2...

OK I ran Untutu again after a reboot and during the end part where it was about to finish it closed away to the default Android home screen with this message "Unfortunately, AnTuTu Benchmark has stopped."

Then with the "Report | OK" buttons but I they don't respond to screen touches, looks like this is a real freeze...

OK I constantly started to get the freeze at the end of every Untutu benchmark run but it stopped once I did the following list of things which may or may not have anything to do with it.

I turned off my TV as it was bluring away loudly (maybe google voice search is listening)

I unplugged the USB power cable.

I decreased screen brightness.

Changed my default desktop background to animated bubbles.

I loaded a few ups in the background (normally I kill apps before a benchmark)

I went into settings and disabled USB Developer mode access.

In security disabled "Allow installation of apps from unknown sources".

Changed "Screen lock' to "Pattern"

Disabled "Make pattern visible"

(Also changed screen settings from auto rotate to landscape mode at this time I think)

I changed my default sleep mode from 2 mins to 10 mins (maybe its that simple)

Updated 3....

I completed a Untutu test with USB cable plugged in (for power) with no issues.... I am choosing to believe that maybe its merely the auto sleep function kicking in at perfectly the wrong time during the benchmark test...

All up I don't think I am going to have any problems using this ROM and am now going to immediately give a paypal donation to Mirek190.

Update 4...

Completed Untutu benchmark with FULL brightness and USB cable powered.

Update 5...

Completed Untutu benchmark with FULL brightness and USB cable powered + I killed all background apps including Untutu, then ran the Untutu benchmark suite with just Untutu loaded.

Update 6..

Completed Untutu benchmark with FULL brightness and USB cable powered + I killed all apps and rebooted the tablet fully then started Untutu benchmark...

Update 7...

Completed Untutu benchmark with FULL brightness and USB cable powered + re-enabled auto rotate mode and picked up the tablet and started rotating it around during the benchmark..

Update 8..

Completed Untutu benchmark with FULL brightness and USB cable powered + left TV blurring away (watching a two and a half men episode)..

Update 9...

Well I don't know why Untutu benchmark was crapping out before but the only other things to try and recreate the problem is to re-enable USB developer mode, change auto sleep back to 2 mins and the other little bits listed above....

Seems stable enough for me anyway.
