Durable phone but too many bugs and glitches that make the phone inoperable
It was very frustrating to use this phone. I have since stopped using it. I was very disappointed in its function. I thought that this phone was going to be hardy and serve my purpose . Endless problems with its use. The torchlight comes on on its own. Mobile data switches on without my knowledge and uses up my money. Random calls were made to my contacts at all hours of the day. I factory reset the phone and saw no improvement. I will not recommend this phone because of its endless problems.
