These days it's so hard to find a smartphone that does it all meaning call reception a big #1, battery life #2, 3G & 4G(some areas) data speeds, web browsing, speaker volume & email accounts...The Photon 4G has all this working flawlessly for me unlike the Evo 3D I had and sold to get this AMAZING well built speed machine.
I live in a bad signal area where getting 4 bars at home will be a miracle :) I had the Evo 4G, Epic 4G & Evo 3D all failed to get even 3 bars in my home all I got from them was 0 to 2 bars. When talking to family over the phone I get disconnected all the time and be forced to stay by the window with my head almost sticking out just to get a strong signal...this happened on all prior phones I had, now with the Photon 4G I get an unbelievable 4 or 5 bars sometimes full with absolutely no disconnects while talking which never happened with any smartphone I purchased living here.
Everyone that I talked to hears me loud & clear and vice versa using either the bluetooth earpiece or phone itself, some say I sounded clearer when using the speaker. At work I get to test 3G & 4G where 4G towers are close by and I get very fast data speeds on 3G and of course even faster speeds on 4G, I browsed youtube, fox.com and downloaded apps with no issues at all. Web browsing on this phone is the best I ever experienced, Adobe Flash works flawlessly with the Photon 4G, flash sites that didn't work on the 3D worked perfect on the MoPho( I did not come up with this nick) lol...Wifi is very strong and downloading apps or browsing has never been faster.
Speaker volume is loud and clear unlike the 3D which was very low and sounded very cheap, battery Life is by far the best on a smartphone to date. Camera takes some nice quality pics although I think the 3D's cam was slightly better...only thing I miss from the 3D was Sense 3.0 UI which was amazing, the Photon has Motoblur or Ghostblur not sure what is called either way htc Sense 3.0 was better and I was forced to download a Launcher from the Market which made me feel a lot better not having Sense. NVIDIA Tegra 2 Dual Core processor makes this phone very snappy with no lag...If you want a smartphone that does it all well the Photon 4G should be your choice! Oh and to end my review its also a World Phone, I call that doing it all :)
