Hahahaha how can u upgrade internal storage.It is as if you are new to smartphones. Please the internal storage is hardware and cannot be upgraded but you can help yourself by putting in a memory card. All the best.

rodgjer, 05 Oct 2015Hi every one...!! please I need urgent help my 640 keep on restarting itself wat exactly shoul... moreI had the same problem. Later, I realised it's because I pressed the POWER button to off the phone. To power off, we actually need to press the POWER button (without letting go), then after a second, instruction will appear to tell you to swipe down. Do so while pressing the POWER button. The phone will now shut down without re-starting.

I have the lumIa 640 lte phone. I use h2o service which is carried on att lines. When my phones shows in on 4g network my internet wont work. When 4g sign goes away and it only says lte my internet works. Unfortunately 99% of the time it says 4g. Tech support at company says it is a problem with the phone not their service. Can you help. I love the phone but the problem gettin data is so frustrating. Thank you.
