E7 was good mobile In the beginning but as time passes by, like every other Samsung phone, the phone starts to lag every here and there. Apps like whatsapp loads only after 8-10 seconds. Also one major problem after 1.5 year is usage is that the phone always shows memory full even if the phone is almost free and all applications are installed in memory card. You need to flash the phone to get rid of the problem but it is only for 10-12 days when it again starts showing memory full. Also dust entering into the screen through the speaker grill. Don’t buy
