I am just sharing my experience regarding Samsung Galaxy Grand Quattro .it can’t satisfied me and it also unable to fulfill any customers criteria. I got some problems in this phone like hanging, shot battery life, touching delay. it’s processor is too poor to run large apps.
You can’t run 3 or 4 apps at a time and has lagging problem. multi touch didn’t work when touching delay occurred. camera quality is not that good, especially front camera really bad.battery is small for this big size phone, when surfing net battery drained fast.
that’s why I won’t suggest you this phone.
