I have a restarting problem with my 620 as well...
I have narrowed the problem down a little... I simply need to shake the phone and it restarts. The phone can be in any initial (turned on) state and moving it around will trigger a restart.
I tried the reset, essentially putting the phone back to 'out of the box' state... gave it a little shake and it reset.
Got the phone from an online Hong Kong store... its unusable in its current state so am working on returning it for repair/replacement (or refund if necessary).
Hope the additional info helps you out.
Thanks for the info redkrispy,
Looks like I'm not the only one with the problem. I can't believe that I bought a new phone that is most of the time in the Care Center! What up with that?
Hey, I have the same problem. Infact I've searched the internet and almost every lumia, even the 920, seems to have this problem. This problem has been here for long time since the start of the lumia series and nokia has not found a solution to it yet!! come on nokia..do some thing or else you'll lose one more nokia loyalist..
i bought a lumia 620, price reasonably ok. It was the start of my frustration, the most stupid unexpected answer I got from nokia service center personnel. Buy phone on Saturday .....4 days later got new micro sim card inserted, the next day sent to service center...... they say my phone microphone cannot work ! ask me to wait 2 to 3 weeks, wait for spare part...idiotic answer.
Will never ever buy nokia ! Pay money now but to use phone maybe 2 to 3 weeks later, real stupid !
You guys out there better be very sure to test new phone before payment, if they allow you, or else buy those brand that allow testing and if cannot better don't buy. You 'll end up like me.!
hi.i bought lumia 620 two days ago.first time using windows phone.i v installed 5 or 6 small apps.now it takes aprox.4 min to switch between portrait and landscape views.rest functioning perfectly.any one can help why it is gotten so slow?
See if your phone works while using multitouch, for one point it's ok, but for 2 or more points it doesnt work, i tested it on 3 lumia 620 and all had this problem, for example, when zooming do it slowly and you will see the screenin "shaking", try a game that require 2 points, for example "rizing". Or just download this app multi touch test or hardware tests, and you can also see this video of one lumia 620 with this problem! http://www.youtube.com/watch?v=_8qL8uaTLac
All lumia 620 users, see if youhave this problem! thanks
My 620 has been restarting ever since I got it. Last night I switched it off. Then this morning switched it back on. Have seen it do 8 restarts since switching on. The only solution I have found is to take off the back, remove the battery, replace the battery, put the back on. This seems to work for about 18 hours. Very annoying. Nokia - PLEASE take note. At least acknowledge the problem
I am having the same freaking problem here........... my Lumia 620 keeps on restarting by its own. with a slight movement, BOOM....... it restarts......... if the phone is put on the table, without any movement or shakes...... it works fine............ but when it is inserted into my pocket...... it restarts. really frustrated with it!!!
I'm facing the same problem with my Nokia Lumia 620 (bought about a month back). When I took the camera back to the dealer, he reset the phone (Settings > about > reset your phone option). This fixed the camera, but the problem cropped up again in another 4-5 days. I have to keep resetting the phone but the problem is this restores the phone to default state each time. What's the permanent fix for this?
