I buy cheap ebay cases. Works for me. Not buying a slim case this time. There's one i like but the seller only posted photos for older G and other brands, not g3. Waiting for more sellers to post. These cases are cheap on alibaba ~$0.70/each minimum order 100 pieces )))) so i won't be getting a good deal on a case. Ordered cheap screen protectors like i always do for all my devices. They work the best and make the screen usable when i wear polarized sunglasses. The screen is weird with all the lines and dots reflecting in sunlight. Hope a protector will block the glare and digitizer reflection.
update: not buying a cheap case this time. One POS case looks good in picture, turned out to be crap. I'm spending a little more money this time.
