Hello Everyone, I am writing this difference between the three phones i.e Samsung Epic 4g, HTC Evo 4g, and HTC Incredible as this question has been asked by a few fellow members and non-members. I will only list the major differences and not similarities/minor difference for the sake of shorter post. Display & Display Size : Epic 4g & Fascinate : Super AMOLED, 16M colors, 4.0" Incredible : AMOLED, 16M colors, 3.7" HTC Evo 4g : TFT, 65K Colors, 4.3" Remarks : SuperAmoled consumes less battery but TFT has more natural colours.SuperAmoled is most vibrant and sharp but at times colors feel unnatural. Dont get me wrong here, but this is of personal taste and you may not even notice a difference. Both Samsung Wins Camera, Secondary Camera, Flash : Epic 4g : 5 MP, VGA , Yes Dual Incredible : 8 MP, - (None) , Yes Dual HTC Evo 4g : 8 MP, 1.3 MP , Yes Single Fascinate : 5 MP, - (None) , Yes Single Remarks : One should not go on specs and see the actual picture to judge the camera rather than mega pixels. It also depends on sensor size which is not listed on any site. I have not compared the cameras myself. EVO Slightly Wins but all have good Performance Processor : Epic 4g & Facinate : ARM Cortex A8 1GHz (45nm dye size Hummingbird eats less power) HTC Evo 4G & Incredible : Snapdragon QSD8650 1 GHz (65nm dye size eats more power) Remarks : Samsung processor is considered best here as it is stated on some sites that it has better graphics acceleration and performance. The actual proccessor performance may be marginaly better but it is considered that graphic acceleration is significantly better. Both Samsung Wins Other Minor Differences : Dimensions & Weight : Epic 4g : 124 x 65 x 14 mm, 155 g Incredible : 117.5 x 58.5 x 11.9 mm, 130 g HTC Evo 4g : 122 x 66 x 13 mm, 170 g Fascinate : 125 x 64 x 10.5 mm, 116 g Fascinate Wins User Interface : Samsung Epic & Fascinate : TouchWiz 3.0 with Built in Swype As per Guarang (Touch Wiz have Better App Drawer where we can make Grouping of Applications, Folders, Quick On Of Button in Task Bar, In build Task Manager Task Killer, App Manager is Breeze), Built in Widget in Samsung is Better Except Clock, 5 Good Live Wallpaper in Samsung EVO & Incredible : HTC Sense (Look Good, Good Clock Widgets) Both Ties Battery : Samsung Epic & Fascinate : 1500 mAh Incredible : 1300 mAh HTC Evo 4g : 1500 mAh Personal Remarks : To me Dimensions and weight hardly matter with such minor differences. UI is a personal preference. I have heard that TouchWiz 3.0 is as good if not better than HTC Sense. Though personally I have just used it for 10 mins. I would personally say that both UIs are having very marginal difference which should not be a major consideration while choosing your phone. Battery life of Samsung Epic 4G will clearly be the best here due to SuperAmoled, though by how much I cannot say. Both Samsung Wins EPIC and Fascnate Gives almost Same life Sound : As per post by Muffy Bhai(mentioned below), Samsung Epic 4G contains wolfson audio chipset with Virtual 5.1 Ear Phones, so audio should be much better than the other 2. EPIC Wins Misc : HTC Evo 4G has mini HDMI Port (used to connect it to a TV/Projector to view the output) Fascinate has Bluetooth v3.0 but no Secondary Call Cam or wiMax (4g), DLNA: Fascinate and EPIC have allShare (Advanced DLNA) so you can Stream Music Phones Audio across Wifi Network, i can Open File Stored in PC on Phone and vise versa, I can play Video Stored on Phone Directly to Samsung or any DLNA Compatible TV EPIC: Yes Incredible: No EVO : No Fascinate : Yes Samsung Wins Scratch Resistence Glasses : EPIC : Yes Incredible : Yes EVO : Yes Fascinate : Yes Scratch Resistence Back Panel: EPIC : Yes EVO : Yes Incredible : Yes Fascinate : No CDMA Radio Throughput EVO : 4.5 Star Incredible : 4.7 Star EPIC : 3.9 Star Fascinate : 4 Star HTC Uses all in one MSM Chipset (CPU(Snapdragon)+Modem+GPS) Samsung Uses Slight Older QSC Chipset (Modem+GPS) HTC Wins in EVDO Speed and overall Radio Performance WiFi EPIC : WiFi N Incredible : WiFi G / (N Disabled to Conserve battery) but Using Custom ROM its Possible EVO : WiFi G / (N Disabled to Conserve battery) but Using Custom ROM its Possible Fascinate : WiFi N Samsung Wins (WiFi N uses less power in Idle Mode and give better Range and Error Corrections) Bluetooth Headset : HTC Wins (Better Reconnection and Reboot Detection) Polished ROM and Custom ROMs : HTC Wins Recovery Process : Samsung Wins ODIN is Simplest (Dont Mess with this though) Overall Looks : EPIC : 3.9 Star Incredible : 3.5 Star EVO : 4.5 Star Fascinate : 4.2 Star EVO Wins Video and Multimedia Performance Samsung WINS - it can play MKV DivX AVI MP4 all using GPU Accelaration, HTC only plays MP4 using GPU Accelaration and all other with CPU Bluetooth File Transfer Samsung Wins Remarks entered above are opinions based on reading a few websites, as I have not got a chance to test the phones personally. They may differ and if you find any remark incorrect, please notify me so that I can correct it. Furthermore, I advice people to read reviews before making a decision. Thanks ! Gaurang
