Htc desire 820 is a flagship phone from htc.
it comes with kitkat android but recently it got an update of android Marshmellow & htc sence 7.
I am an avid HTC Fan and I have used HTC One and HTC One M8 and I must say that HTC makes great smartphones. Here I ll give pros and cons.
FEATURES:
PROCESSOR: This is an octa core device clocked at 1.5 GHz(4 cores), 1 GHz(4 cores) and which makes the phone really smooth to use.
DESIGN:Design is again a plus point. No one designs phones like HTC, period. The white color looks stunning with double tone colors.(Look at samsung devices, they are pathetic)
CAMERA: Desire 820 sports an 8MP camera which takes great pictures. There are some software features which make it stand out from others.
SOFTWARE: HTC sense is the smoothest bloat UI in market, dont belive me? Google the reviews.I have been using their smartphoens for 3 years now and They are super fast without any lags.
DISPLAY: Display is not full HD(They have to cut the costs somewhere) but its good. It has 5.5 inch sceen which is great to watch movies.
SOUND: BoomSound, need I say more? for those who do not know, BOOMSOUND is absolutely killer and the best sound system you will find on any smartphone. They are loud, crisp and the lows, mids and highs are perfect.
CONNECTIVITY: 4G at this price? unbelievable for an HTC device. It supports all other connectivity options like WiFi, 3G, Bluetooth etc
BATTERY: 2600 mAh seems small but M8 has the same battery with full HD screen and lasts for more than 1 day. So this device will give you good backup as it has only 720P screen.
RAM: 2GB RAM is great. good for multitasking.
PROS: BoomSound, Sense 6 UI, Design, Performance, 4G
CONS: 720P screen(but they have to cut the costs)
So go for it, Only issue is heating. If you are one of those guys who compare Xiaomi, Huawei to HTC then this might not be the phone for you. Its costly but hey, its HTC. HTC is a better brand than these brands, they are with us since 1997(they made the first android smartphone, first Microsoft powered phone, first windows 3G phone, first 4G android phone, first nexus phone, first FB phone and the list goes on) so dont do that please. Go and buy it and support a brand which is struggling even after making the best devices.
