I had one of these, became unusable (due to ghost touchscreen inputs) unless the brightness was turned right down to the minimum, both when on charge and when not.
Can't understand why this is getting any heat.... old phone now with widespread ghosting issues, not even the Plus version.
G4 was sent back after 6 months due to ghosting, annoying.
No ghost touches on my g4. Great phone, only changing it (after 10months) because it's too large for me, and I've got big hands! The g4 is not waterproof, the G3 was. Mine has recently in the last couple of months started to screen burn, but it's not permanent. The burn goes away completely in a few mins with either the phone screen off or just by watching a few YouTube clips.
A good price for a very good phone. My wife and I both have the G4 and never had the ghost touch issues. However mine has developed screen burn in. Apart from that, it's a really good phone for the price.
