Okay, So i have Bold 9900, from about 5 months now
The thing that was so annoying was since i upgraded to OS 7.1.0.342, I was facing this weird issue about space bar if i write lets say
hello. how are. you ?
I was getting this full stop for no reason, and i knew it its a software thing because when i was on OS 7.0 (that was shipped with this phone) i never had this issue i wasn't even aware of it cause i never had it
So all i have done is (uninstalled all everything all the OS's) and installed 7.1.0.523 (even tho i was on it and i had this issue) i installed it through DM (it recognized it as a new upgrade) and that was it and i only got that (.) period, once and i have noticed it was my fault i did double clicked it
Hope this helps for those don't have the hardware issue.
