I've bought Lenovo A850 from China 9 months ago.
It was working fine, but now it may work for minutes (sometimes for a hour) then it's turned off suddenly (no messages, no vibrations, nothing). when I try to turn it on, it may be off again on lenovo startup logo, or startup music, or after many seconds from the android system start. After many trials it will not be on normally, I have to wait for minutes then it may be turned on but it will be off again after few minutes.
I flashed the phone with many different roms and all of these roms have the same problem?
I think this may be a hardware problem!!! (I can't ship it back to China)
Any help please?
No one have an Idea?!

Hi to all, I have recently bought a this phone and from the second day of life sometimes when a call is incoming (or a message) the phone freezes and reboot. Sometimes it happens also when I connect the phone to charger or when I press the button for turning on the display.
Phone is not rooted, rom is original.
I have already upgraded firmware to the latest version from Lenovo, but the problem still presents.
Model: Lenovo S820_ROW
Android version: 4.2.1
Baseband version: S820.V21, 2013/08/07 15:14
Build number: S820_ROW_8G_S121_131128
I've seen on Lenovo forum that there are others in my situation.
Does anyone have a solution or a workaround for this issue?
Thanks

After about 20 days of experiments, I noticed that the reboot issue was often connected to the screen lock part.
I have turned off this feature for one or two days, remembering to push the power button before putting in the pocket...
I now can say that this bug is extremely decreased, and it doesn't happen anymore during a call or a message.
I have downloaded a different screen lock app from market and disabled the internal.
It happened just a couple of time but I'm not sure that is connected to the lock screen app (Iphone5s Lock), I will try other apps
Just a few ago a call AND a message arrived in the same moment and the phone did what was supposed to...
Hope this helps
Bye

First sorry for my english
My note edge turns on and restart or freeze and then i had to take the battery out to turn it off.
Thought it is a software problem and have updated to Marshmallow 6.0.1 but still the same problem. Some days just 1-2 on offs with freeze... Some days 8 times one after the other. When it Charge there are often freezes.
I have 2 note edges. On the other i updated Marshmallow too. This edge has had never problems.
When i compare the two device information in android menu the edge which runs perfekt has never se for android. Could this be something why it turns of...
And why one is never...
You could try wiping the cache, or wiping the data (resetting your phone) and starting over with a fresh system.
It always restart when android made automatic updates. Now i disabeled autimatik updates and since 2 days no problem with restarts.
But now have another problem.... When i play musik with the musik player or hear voicemail via whattsapp there is sound for 3-5 seconds and then you can't hear anything. The musik in Player goes on but you cant hear anything after 3-5 seconds.... Grrrrr

Hi guys! A few months ago I bought Mi4c and got one little but very annoying problem: whenever I turn off the screen and ~1 minute passes its just reboots itself. Sometimes it goes to Sleep of Death(state when phone have no reaction on anything and can be rebooted only by 10-seconds power key hold). I tried everything: flashing latest MIUI from miflash and even from edl_download mode, its has no affect so I unlocked bootloader and tried to flash custom rom I've tried cm12, 13 by Teamsuperluminal, Ressurection Remix M, Mokee, etc. but problem still exists.
Now I'm use CPU Awake from Google Play to avoid my phone go to sleep mode, but it's not a solution.
Anybody know how to fix it?
I'm pretty sure that's a defective unit honestly. Have you tried contacting your reseller?
Hello everybody! My phone (SM N915F) has a problem of stuttering/lag spike. Every 7 to 15 seconds phone gets stuck for about 1 second. When using an app (say, camera) every 4-6 seconds I get a lag spike. I tried to solve this myself, I checked if this is a software problem (changed rom, 3 different roms), tried in recovery if it lags (it does not), tried other apps etc. I checked logcat to see what happens when phone gets stuck, I saw a service(?) choreographer says "choreographer skipped N frames", which as I searched on internet, choreographer syncs apps with display, so actually screen does not gets rendered for N frames for no reason. Did anybody ever had this issue? I have assured there is no storage problem.
Hello,
got my Note10+ and installed exactly the same apps as in my Xiaomi Mi Mix 3.
During several days and several phone calls the Note10+ freezes during the calls. No UI possible. Black Screen. Sometimes reboots automatically. Sometimes i had to interact.
Update:
i resetted the phone and result the same. Call is running 2-3 minutes and screen goes black. The call is still running. Few seconds afterwards nothing works anymore. Phone freezes.
Anyone similiar problems?
thx
