Connectivity issues as in randomly dropping data? Every 4g device that me and my girlfriend have had including stratosphere, thunderbolt, rezound, have all had data connectivity issues. My stratosphere was replaced by the D4 i am using now. Ive had it for about a month and ive had data drop once. Every time i tried to open the play store my data would drop. I have read this has something to do with how the devices switch from 4g/3g. I was in an area that does not have strong 4g. I rebooted to fix the problem and it hasnt happened since.
However. With the other 4g devices that I have had they all started off working great then a few months down the road I get a few data drops even when I was not using the phone. After awhile it became very frequent the data would drop countless times within an hour. factory reset did everything I could think of and it didnt solve the issue.
To be honest it think it is something to do with the verizon network or something with the sim cards, I really dont know since it seems to me its all the 4g devices having problems. I called verizon and asurion enough times in one night they finally sent me a replacement phone.
My uncle has also gone through 3 droid 4 phones because the ear piece always burned out of them. He finally complained enough they gave him the razr maxx.
in my opinion, complaining enough works
