    Pros: Screen Clarity,Performance,Dual Sim stand by

    Cons: Have identified two cons so far

    Overall: Pros: -Clarity of the screen is very good and high quality pictures are sharp. -Its operating system is fast. -Good sound quality of music and videos. -Blutooth adds up as an advantage. -Dual sim works like a charm. -Well tuned mobile for budget people who dont want a camera. -Battery goes on and on and on without charging for days(tried max 4 days) Cons: -Cant change my screen saver from the factory default -A defect in my mobile it hangs for 10 secs after i end a call session..may be its my phone specific defect -I was able to read PDF files before adding my memory card but after adding my memory card i was unable to use ebook reader -Ear phones are plastic made so a liltle irritating for ppl with soft ears... get a good ear phone and flaunt 3.5 mm jack I face few issues of 10 secs hang period after call is completed... but i ignore it as i dont get disturbed in the middle of the call. I have doubled it as my music phone. I am very satisfied with this phone coz it didnt pinch me much in my budget.. Good for ppl who want a phone without camera and in low budget

  • awesome!!!
