I am using HTC Desire 826. The quality is good and it is easy to use, but there is high problem of battery backup. Battery discharge so early and also it heats while charging. if you use 3G internet the battery get discharge so early. The sound quality and style is good. HTC service center is not providing 1 year warranty and if you buy from online sites, they will not provide you the proper warranty. Be Careful before buying.
