YESTERDAY I DOWNLOADED A THEME FROM GO LAUCHER AS SOON AS I INSTALLED MY TAB AOTMATICALLY RESTARTED BUT NOT SHOWING MAIN SCREEN INSTEAD CYNAGEN MOOD RUNS
AT TIMES MAIN SCREEN COMES AND BEFOR I COULD LOOK ONTO IT AGAIN CYNAGEN MOD COMES AND DISPLAYS ITS ICON
PLZ HELP ME
- There is no punctuation whatsoever
- While there is lower-case and upper-case text, there's no mixture. It started out all lower-case and then became all upper-case. (Too tired to press the CapsLock key, I guess)
- Obvious spelling errors
- Concludes with "PLZ HELP ME"
Surely our quality standards filter is better than this?
