I recently got a tablet rk3026. His intended use was as a ebook reader for my nephew, no internet, no facebook, some wifi to access my server.

Problems: 

1. after 3..5 minutes, from 100% battery, it shuts down. Checked the battery voltage, is ok, the tablet reported it bad (cpu-z, android battery info). The true capacity may not be 2500mAh but, anyway....

2. the screen ratio is wrong. A circle (the analog clock) is a ellipse. Both on portrait (more visible) and landscape mode.

I rooted with the tutorial on this blog http://galindaines.blogspot.co.ke/2015/02/tutorial-root-y-flasheo-tablet.html, was ok

Calibrated the battery with this app https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=es

specs: model rk3026; Android 4.2.2; kernel 3.0.36+ yudongsheng@ubuntu#435 Fri Aug 22 13:49:45 CST 2014

compilation rk3026-eng 4.2.2 JDQ39 eng.yudongsheng.20140905.164945 NTP

On his back: model no:759 and states that the battery is Li-ion 3.7V 2500mAh

Cpu-z tell me that the screen is scaled at 800x480, 140dpi, 6.66inch

It have 1G storage and 512M RAM (on the board is a free place to solder another flash. What if...?)

So, my question is: Is there a rom that I can flash to fix the battery and screen issues?

If needed, I have the backup (dump) the original system images, and I may post fotos from the inside of it.

Let me have a dmesg log.

Is this one?

While the battery was able to power the tab 44sec from 100% to shutdown, I change it with a new huawei 2400mAh. Now, after I charge to full, the tab take almost 24 hours to shutdown (no wifi, medium light). 

The screen is a 773PTG700V65001 device, listed to have 960x640 native resolution. The CpuZ say that the resolution is 800x480. 

Is there a way to send installed apps to external_sd intsead to the sd? Because the sd is internal flash storage and external_sd is the sd card.
