[Galaxy S 4 Q&A, Help & Troubleshooting] ianbbaa:
Also sold my first S4 2 months ago cause of - weak 3G signal, camera was not that great inside (outside was great), battery was not best and not bad. I sold it still on 4.2.2 and didnt know about planned ANT+ support which i personally can use. (I am also using ANT+ on some devices via OTG + SUUNTO ANT+ ministick - works great!)

So i was 2 months, sweating with my old XPERIA NEO rocking CM10 considering HTC ONE, LG G2.

pros/cons of HTC ONE for me - my friend has it so i ve used it quite often when i could.

cons - wake up button at the TOP for my small hands, build in battery!!! I had bad experiences with previous HTCs - 1year and battery is dead, i do not want to send it for service, NO SD CARD, camera - less details in sunlight....

pros - display, 32GB (when no SD - 32 is better than 16), camera - yeah, also in cons but low light pics are very good, build quality and feel in hand,

G2 cons/pros had it for one day and also done a lot of research over the web:

cons - build in battery, no SD, 16GB only (16GB only available in my country), knock on unstable, more bloat than S4, so far bad name in updates for LG (when those bugs will be fixed???!!!! Camera - yes, in cons, it is great camera but i d say the same as in S4. Focus hunting bug was in present at my device!!! G2 is a bit sensitive to falls, if i accidently drop my device and crack the screen - i want at least to use it - G2 can not be operated anymore even a small crack appear - that means no call even you are somewhere and need your phone for urgent case. Bad resale value!!!

pros - battery life, display, Knock ON (when it works),

So i got back to S4 - currently on 4.3 and i have - no problems with 3G as on my previous S4 (might be firmware issue), battery life is definitelly better, ANT+ build in.

So pros of S4 - camera sun light, battery life not as on G2, but definitelly good one for me - and easily replaceable when needed, SD card 9built+64gbSD!!!, ANT+, good base of development - if i mean SAMSUNGs updates or XDA comunity, best EAS i quess, when you drop S4 - still can be operated even on full spiderwebbed screen - easily replacaple front glass, not the case of those 2 above. Perfomance boost on 4,3 over 4.2.2 (same antutu on S4a S600 4,3 than G2s S800 - but i do not play games at all, do not need thar power anyway and believe G2 will smoke them all if upgrade will come)

cons of S4 - camera low light can be better - but is better than 4.2.2, not easily handling root and things after 4,3 - KNOX 0x0 etc...display - i thing LCDs on those 2 above are a bit better. not as good build quality as HTC ONE but i do not squeeze it for fun to reveal some cracking anyway. S4 is solid, but i like that all "plastic" parts can be easily replaced - full chassis after 1 or 2 years for cheap (anyway do not keep device for 2 years long)

So S4 is to time best device out there, for me at least.

I had also quick look at SONY Z1 (has also ANT+) - no, no SONY at all...huge as NOTE 3, bad battery life, my friend has Z and it is worst phone i ever hold in my hand for that price. Very expensive at launch, resale value bad, heating, camera not as good as promised....

I was also NOTE 1 user, so N3 might be it but i find S4 the perfect size for pocket and work. And for S-PEN use i have NOTE 8.
