Hello friends, the Xelectron W99 is the tablet which is the worst in its perfomance. At the begining I was happy that this tablet works good but later the tablet is worst in its perfomance and is totally opposite in its function. This tablet has 512 MB RAM and 4 GB ROM and the memory is expandable upto 32 GB. Having a 512 MB RAM won’t make a processor to perform smoother. The tablet hangs a lot so that we get irritated too much. The inbuilt apps occupies 2.5 GB ROM space so that we cannot download many applications. The storage space becomes full faster because of lesser storage. It works on the built in processor of 1.2GHz cortex A8 with a chipset of Boxchip A13. This processor doesn’t perfom good in its function and this leads to get the tablet heated while charging and playing games and internet browsing. It has a rear camera of 2 MP and front camera with 1.3 MP. Both the camera quality is very poor. It has 3200 mah battery capacity though its stand by is very bad after few months it not even withstand for 2 hours. I suggest my friends that not to buy this tablet. Don’t waste your money buying this waste tablet.
