Lenovo A6000 was the best phone while ut was realising.Its having 1.2ghz quad core snapdragon qualcom processor, Adreno 306 gpu, 1gb ram, android 4.4.4 which can be upgraded to 5.0.2 lollipop, 5 inc. Screen, 8mp back and 2 mp front camera, with hd display, 8gb internal storage.But as I mentioned it was the best phone. I purchased this phone mad played many games without any lag like NOVA 3, modern combat 4 and 5, real racing 3, asphalt 8, The dark knight rises and many more heavy games.it was costing 6999/- but after some time lenovo realised A6000+ which had 2gb ram, 16 gb rom and was only 500 rs more costly than A6000 So I felt a little bit cheated.
However, The sound quality is very very good becuse its having Dolby digital plus sound, sound effects are best.but updating it to 5.0.2 lollipop will kill the phone.from the time I updated the phone it lags, hangs very much, many apps do not install, camera quality has become a bit bad, and games also lags a little bit.so if you are buying the phone its my request to you please dont update it.thanku!
