S3A Stability Update and USB Cable Charging Problem

My S3A seems a little more stable but still acts a little flakey. The Google PlayStore app usually installs new apps and updates existing apps without crashing. However, I still get occasional PlayStore app crash notification screens. Once the crash is acknowledged the PlayStore app always restarts fine.

The AnTuTu benchmark still hangs on the 3D part or "pauses" during the 3D benchmark. If the 3D benchmark hangs for a second or two the overall AnTuTu benchmark value for the 3SA goes to ~38,000. If the 3D part of the benchmark completes without a pause then the best I have seen for the S3A is ~40,500. If they solve&improve the 3D values in the AnTuTu benchmark the S3A values would be world class.

The S3A seems to charge the battery A-OK but the phone cannot be operated with the charging cable (jiayu provided) plugged into the S3A and a power source (USB p/s, PC USB port, etc.). When plugged into the charging port the touch screen of the S3A goes haywire. The phone can be unlocked but the keyboard will show six characters or more typed before you touch the keyboard. Buttons on the current screen are "touched" even before you can touch the screen. Unplug the S3A micro-USB cable and the S3A returns to normal.

This means that one CANNOT use the S3A while you are charging the battery ! 

Wondered if anyone else has seen this issue with the touch screen and the charging cable??

The jiayu.es app is useful, but it is entirely in Spanish. So it seems we have only Chinese and Spanish language supplied tech support. :(

The jiayu.es app says the following about my S3A:

- Model: S3A

- Compilation: S3S 20150324-194940

I did the ROM update from the jiayu-store website and the install Google PlayStore app&procedure from the "News" tab on the jiayu-store website. Wondered if what is noted above means I have the "best" ROM for my hw and uses (i.e. want Google PlayStore, English, etc.).

Several posting says that http://www.needrom.com/download/s3s-nfc3gb-ram-2015-02-13/ has the best ROM (ROM1) for the S3A that wants Google PlayStore and English. The details of this ROM are below:

ROM1: RC_mt6752_h560_s3sw_jyt_cc_128-24_kk_lte_5m-cs_mul_tphone_20150213-171816_songlixin_PC

–> this ROM you have to flash via FlashTool (PC)

–> GooleApps are included

Wondered if this is the "better" ROM for my S3A? I wonder as the version #'s are LOWER than what I have installed and therefore not as new with all the bug fixes needed?

I installed the CWM boot backup/restore app from jiayu.es download and the cool Flashify app (obtained from Google PlayStore) which does not require a cable&PC install requirement (requires root though). CWM seems to work fine and allows full backup of ALL sw/data to SD card.

The S3A does an excellent job casting Spotify over DNLA. The CPU utilization (supplied by AnTuTu) seems to peg out around 25-30% while the S3A just does audio casting. I can bring up several apps, read Flipboard etc. and play the music without a problem or pause in casted sound. The Spotify and BubbleUPNP apps also seem to run fine and don't lock up or otherwise misbehave. :)

All feedback is welcome.
